BEFORE YOU START!! READ, UNDERSTAND, and FOLLOW the information provided in this manual, the AEM Mower Safety manual and the tractor operator's manual carefully to learn how to operate and service your machine properly. Failure to do so could result in personal injury to you and bystanders. All implements with moving parts are potentially hazardous. Every effort has been made to ensure that the machine is safe but operators must avoid engaging in unsafe practices and follow the written instructions provided. The manufacturer has designed this implement to be used with all its safety equipment properly attached to minimize the chance of accidents.

SAFETY FIRST. Completely read and understand the safety section of this manual before operating this equipment. Do not allow anyone to operate this equipment who has not fully read and understood this manual. Contact your Dealer to explain any instructions that you do not fully understand.

The care you give your Rhino Implement will greatly determine your satisfaction with its performance and its service life. Carefully read and follow the instructions in this manual to provide you with a thorough understanding of your new implement and its intended use and service requirements.

All references made in this manual to right, left, front, rear, top or bottom are as viewed facing the direction of forward travel with the implement properly attached to the tractor.

Replacement Parts information is located in a separate Parts Manual. Rhino mowers use balanced and matched system components for blade carriers, blades, cuttershafts, knives, knife hangers, rollers, drivetrain components, and bearings. These parts are made and tested to Rhino specifications. Non-genuine "will fit" parts do not consistently meet these specifications. The use of "will fit" parts may reduce mower performance, void warranties, and present a safety hazard. Use genuine Rhino mower parts for economy and safety.

For future reference, record your Rhino product model number and serial number.

In order to reduce accidents and enhance the safe operation of mowers, Alamo Group Ag Division, in cooperation with other industry manufacturers has developed the AEM/FEMA Industrial and Agricultural Mower Safety Practices video and guide book.

The video will familiarize and instruct mower-tractor operators in safe practices when using industrial and agricultural mowing equipment. It is important that Every Mower Operator mowing equipment and be able to recognize the potential hazards that can occur while operating a mower. This video, along with the mower operator’s manual and the warning messages on the mower, will significantly assist in this important education.

Your Authorized Rhino Dealer may have shown this video and presented you a DVD Video when you purchased your mower. If you or any mower operator have not seen this video, Watch the Video, Read this Operator’s Manual, and Complete the Video Guidebook before operating your new mower. If you do not understand any of the instructions included in the video or operator’s manual or if you have any questions concerning safety of operation, contact your supervisor, dealer or Alamo Group Ag.

If you would like a VHS video tape of the video, please email AEMVideo@alamo-group.com or Fax AEM VHS Video at (830) 372-9529 or mail in a completed copy of the form on the back of this page to AEM VHS Video 1502 E Walnut Street, Seguin, TX 78155. and request the VHS video version. Please include your name, mailing address, mower model and serial number.

Every operator should be trained for each piece of equipment (Tractor and Mower), understand the intended use and the potential hazards before operating the equipment.

INTRODUCTION SECTION

Introduction Section 2-1

INTRODUCTION

We are pleased to have you as a Rhino customer. Your Rotary Cutter has been carefully designed with care and built with quality materials by skilled workers to give maximum service with minimum down time. This manual is provided to give you the necessary operating and maintenance instructions for keeping your rotary cutter in top operating condition. Careful use and timely service saves extensive repairs and costly downtime losses. Please read this manual thoroughly. Understand what each control is for and how to use it.

Rhino typically offers three types of shielding to protect the operator, passerby, livestock, and property from thrown objects... deflectors, single chain guards, and double chainguards. Shielding should be selected based on the intended use of the mower. Double chainguards or deflectors should be used for highway, right-of-way, parks or greenbelt mowing or all other mowing where human dwellings, vehicles, or livestock could be within 300 feet of the mower. Chainguards are more durable, provide a longer service life and require less maintenance and replacement than deflectors. Single chainguards may be sufficient for agriculture and other mower use only where passersby or property are not within 300 feet of the mower during operation.

No shielding is 100% effective in preventing thrown objects. The possibility of injury and property damage from this hazard can be substantially reduce by selecting proper shielding, maintaining the mower and shielding in good operational condition, inspecting the area for foreign debris before mowing, operating the mower at a minimum cutting height of 4", and keep unprotected persons at a minimum distance of 300 feet from the

INTRODUCTION

mower at all times during operation.

Safety is of primary importance to the owner/operator and to the manufacturer. Observe all safety precautions decaled on the machine and noted throughout the manual for safe operation of implement. If any assistance or additional information is needed, contact your authorized Rhino dealer. The owner/operator/dealer should know and understand the Safety Messages before assembly and be aware of the hazards of operating this cutter during assembly, use, and maintenance. The Safety Alert Symbol combined with a Signal Word, as seen below, is intended to warn the owner/operator of impending hazards and the degree of possible injury faced when operating this machine.

Indicates an imminently hazardous situation that, if not avoided, WILL result in DEATH OR VERY SERIOUS INJURY.

Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH OR SERIOUS INJURY.

Indicates an imminently hazardous situation that, if not avoided, MAY result in MINOR INJURY.

Identifies special instructions or procedures that, if not strictly observed, could result in damage to, or destruction of the machine, attachments or the environment.

INTRODUCTION

The Rhino 260/272/284 Rotary Mower is designed for medium duty applications such as weed, grass, corn stalks, and light brush to 2" diameter. These mowers are single spindle with two free-swinging blades. Free swinging blades reduce the shock of impact when a stationary object is hit. Additional protection is provided by a slip clutch on the gearbox input shaft. A round blade holder allows the mower to “ride over” stumps and similar immovable objects. These Mowers are attached to the tractor using 3-point Cat II or III standard or quick hitches or pull hitches. Standard equipment includes driveline shields, clutch shields and front and rear discharge shields.

KEY OPERATION POINTS

• Cutting performance and distribution are best when cutter is level from side to side and front to rear.

• In extra heavy material, rear chains will allow better discharge and better distribution than solid rear bands.

• Never operate the Mower below full PTO speed of 540 or 1000 rpm.

• Corn should be cut at 5 to 6 mph. If full PTO rpm cannot be maintained, use one lower gear.

Operating Noise Level/Sound Pressure

The sound levels at the operator's ear from the attached machine (rotary cutter) are at least 10 dB(A) below the levels from typical Agricultural tractors used to power and transport this machine. Therefore, the Noise emission values given by the OEM of the Agricultural tractor used to power and transport this machine would be valid when this machine is attached to and operated by that Agricultural tractor in all OEM recommended applications.

OPERATION

2.2 Tractor Safety Devices

If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped with proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of the unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor warning signals are obscured.

Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were removed for access to connect, service, or repair the tractor or implement. Never operate the tractor PTO with the PTO master shield missing or in the raised position. OPS-U- 0004

Tractor Horsepower

The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing conditions, the 260 mower requires a tractor with at least 35 HP, the 272 mower requires a tractor with at least 45 HP and the 284 mower requires a tractor with at least 65 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine. Exceeding 90 HP (Model 260) and 100 HP (Model 272 & 284) may cause mower damage by overpowering the unit in heavy cutting conditions.

2.3 3-Point Hitch

The tractor 3-point hitch must be rated to lift at least 1000 lbs. (Model 260), 1200 lbs. (Model 272) and 1500 lbs. (Model 284). The Model 284 is designed to be mounted on a tractor with CAT II or CAT III 3-Point or CAT II Quick Hitch.

Refer to the tractor operator’s manual for the category of the tractor being used. If the hitch does not conform to ASAE dimensions, the mower may not fit or raise properly. Consult an authorized dealer for possible modification procedures to mount non-conforming hitches.

Depending on the hitch category, certain size pins are used to attach the mower to the tractor. CAT I hitches require 7/8” lower and 3/4” upper diameter hitch pins. Quick Hitch requires 1-7/16” diameter lower pin and 1-1/4” diameter upper pin. CAT II hitches require 1-1/8” lower pins and 1 inch upper pins. CAT III hitches require 1-7/16” lower pins and 1-1/4” upper pin diameters.

Our 3-Point Quick Hitch is designed to connect to a Quick-Attach coupler making mounting and dismounting your mower easier. The 3-Point Quick Hitch is also designed to connect the mower to a tractor’s 3-point linkage without the use of a Quick-Attach Coupler.

OPERATION

260/272/284 01/11 Operation Section 4-5

OPERATION

2.4 Front End Weight

A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005

2.6 Power Take Off (PTO)

This mower is designed to operate at a PTO speed of 540. Most tractors operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft. Those operating at 540 RPM will have a 6-spline shaft and those operating at 1000 RPM will have a 21-spline shaft. Note: Only the 284

mower can be ordered to operate on tractors equipped with a 1000 RPM 21-spline shaft. Refer to the tractor owner’s manual for instructions to change PTO speeds on models that operate at more than one speed.

If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an over-running clutch must be used between the PTO output shaft and the driveline of the mower. An authorized tractor dealer can provide the over-running clutch and its installation if needed. OPS-R- 0066_A

2.5 Drawbar-Pull Type Mower

For equipment operating at 540 RPM, the tractor drawbar must be positioned at a 14” distance from the hitch point to the PTO shaft end for proper operation and minimal wear to the driveline. 1000 RPM 284 Models require 16 inch drawbar length.

If attaching the mower tongue clevis to a 3-point hitch

OPERATION

drawbar supported by the lower lift arms, the attaching point must be extended past the main bar to allow for turning without binding the clevis and bar. Lift arm stabilizers must be used with this type of drawbar to prevent the mower from swaying from side to side.

OPS-R- 0061_I

260/272/284 01/11 Operation Section 4-6

OPERATION

DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor

PTO. Use of an adapter can double the operating speed of the Implement resulting in excessive vibration, thrown objects, and blade and implement failure. Adapter use will also change the working length of the driveline exposing unshielded driveline areas. Serious bodily injury and/or equipment failure can result from using a PTO adapter. Consult an authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.

(S3PT-14)

Never operate the Tractor and Mower if the Implement input driveline is directly connected to the Tractor transmission. Tractor braking distances can be substantially increased by the momentum of the rotating Mower blades driving the Tractor transmission even though the Tractor clutch has been disengaged. Install an over running clutch between the Tractor PTO and the Mower driveline to prevent this potentially dangerous situation.

(S3PT-16)

3. GETTING ON AND OFF THE TRACTOR

Before getting onto the tractor, the operator must read and completely understand the implement and tractor operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for a complete explanation. OPS-U- 0007

Do not mount or dismount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completelystopped.

(SG-12)

3.1 Boarding the Tractor

Use both hands and equipped handrails and steps for support when boarding the tractor. Never use control levers for support when mounting the tractor. Seat yourself in the operator’s seat and secure the seat belt around you.

Never allow passengers to ride on the tractor or attached equipment. Riders can easily fall off and be seriously injured or killed from falling off and being ran over. It is the operator’s responsibility to forbid all extra riders at all times. OPS-U- 0008

Never allow children to operate, ride on, or come close to the Tractor or Implement. Usually, 16-17 year-old children who are mature and responsible can operate the implement with adult supervision, if they have read and understand the Operator’s Manuals, been trained in proper operation of the tractor and Implement, and are physically large enough to reach and operate the controls easily.

(SG-11)

4. Turn off the tractor engine and dismount.

5. One lift arm at a time, align arm end hole between the set of A-frame lift lugs. Insert hitch pin through the lug and arm holes and insert retaining pin into hitch pin.

6. Walk around to opposite side and repeat procedure for remaining lift arm and hitch pin.

7. Extend or retract 3-point top link to align its end hole with the holes of the mower’s top link. Insert the top link hitch pin and insert retaining pin into hitch pin.

8. Adjust any lower link check chains, guide blocks, or sway blocks to prevent the mower from swaying side to side and possible contact with tractor rear tires.

NOTE: Offset Adaptor Hitches are available to position the mower to the left or right. Mowers with Offset Adaptor hitches connect to the 3-Point hitch the same way as the mower A-frame. See Offset Adaptor Hitch in the Assembly Section for details to equip the mower with this feature.

OPERATION

5.2 3-Point Quick Hitch

Our 3-Point Quick Hitch is designed to connect to a Quick-Attach Coupler making mounting and dismounting your mower easier. The 3-Point Quick Hitch is also designed to connect the cutter to a tractor’s three-point linkage without the use of a Quick-Attach Coupler.

260/272/284 01/11 Operation Section 4-10

OPERATION

5.4 Safety Tow Chain

If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the gross weight of the mower must be connected between the tractor and mower. This will help control the implement in the event the tongue becomes disconnected from the drawbar. Make sure the chain is attached to a secure location on the tractor and not to an intermediate support.

After connecting both ends of the safety chain, drive the tractor to the right and left to check for proper chain length. Adjust length as necessary and allow only enough slack in the chain to make a maximum turn in both directions. When not in use, store the safety chain to protect it from mud or standing water by wrapping the chain around the tongue. Replace the safety chain if one or more links or end fittings are broken, stretched or otherwise damaged or deformed. OPS-U-0039

5.3 Connecting Mower - Lift Type (Quick Hitch)

Crushing Hazard between Quick-Hitch and Implement. Do not allow anyone to stand between the Quick-Hitch and implement during hook-up operations. Never operate the hydraulic 3-point lift controls while someone is directly behind the tractor.

1. Make certain the implement’s upper and lower hitch pins are secured.

2. Lower the tractor’s 3-point lift until the three Quick-Hitch hooks are lower than the implements hitch pins. Carefully back the tractor to align the Quick-Hitch hooks under the implement’s hitch pins.

3. Slowly raise the tractor’s 3-point lift until the lower Quick-hitch hooks lock into place over the implement’s 3-point hitch pins.

IMPORTANT: Make certain the implement’s top 3point hitch pin is captured by the Quick-Hitch top 3point hook. If not consult your Quick Hitch manual for required adjustment.

IMPORTANT: The Quick Hitch will more mower further from tractor which will require checking the following:

1. Driveline length

2. Tractor stability

NOTE: Offset Adapter Hitches are available to position the mower to the left or right. Mowers with Offset Adapter Hitches connect to the 3-point hitch the same way as the mower A-frame. See Offset Adapter Hitch in the Assembly Section for details to equip the mower with this feature.

260/272/284 01/11 Operation Section 4-11

OPERATION

6. SETTING THE MOWER

Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of uneven terrain. NOTE: Avoid very low cutting heights, striking the ground with the blades gives the most

damaging shock loads and will cause damage to the mower and drive. Blades contacting the ground may cause objects to be thrown out from under the mower deck. Always avoid operating the mower at a height which causes the blades to contact the ground. OPS-U- 0010

Never work under the Implement, the framework, or any lifted component unless the Implement is securely supported or blocked up to prevent sudden or inadvertent falling which could cause serious injury or even death.

(SG-14)

6.1 Setting Mower Height- Lift Type - (Standard or Quick Hitch)

OPERATION

1. Park the tractor and mower on level ground.

2. Using the 3-point hitch control lever, position the front of the mower with the side skids 1” less off the ground than desired cut height. For example, for a 3” cut, position the skids 2” from the ground. Set the 3-point control lever stop at this position to maintain this height when raising and lowering the mower.

3. Shut down the tractor and remove the key.

4. Adjust the mower deck front to rear by extending or retracting the 3-point top link. Always set front of deck 3/4” lower than rear for best performance.

5. Level the mower side to side by manipulating one lower lift arm length. On most tractors, at least one of the lift arms is designed to allow for manipulation of its length. Shortening or extending will allow for deck leveling from side to side.

6. Securely block up the mower at this height.

7. Remove the bolts securing the tailwheel beam in position and allow the tailwheel to rest at ground level. Align tailwheel beam between nearest sets of holes in beam support brackets and reinstall support bolts on each side of beam. Tighten all bolts and nuts.

260/272/284 01/11 Operation Section 4-12

OPERATION

8. Extend the tractor’s top 3-point link so that when lifting the mower, the front of the deck will raise 2 to 2½” before the tail wheel leaves the ground. This will allow the mower to follow the contour of uneven terrain.

OPERATION

NOTE: Install optional check chains when there is a problem with the hydraulic 3-Point lift maintaining a set height or when a constant pre-adjusted cut height is required. See Check Chains in the Assembly Section for this accessory.

260/272/284 01/11 Operation Section 4-13

OPERATION

6.2 Connecting the Mower-Pull Type

1. Make sure the tractor is equipped with the correct PTO shaft and the drawbar is extended 14” from the end of the PTO shaft to the hitch point.

2. Block the mower wheels in place and use the attached parking jack to raise or lower the tongue clevis to the height of the tractor drawbar. The parking jack can be rotated 15 degrees in each direction to obtain a near vertical position. Note: Always place jack foot on firm surface or place board under jack for support.

3. Board the tractor and start the engine. Back the tractor to the mower aligning the drawbar hitch hole with the mower hitch clevis. Turn off the engine, secure the tractor in position, and

OPERATION

dismount.

4. To attach the mower, place two 1” flatwashers (1) positioned under top lip of tongue clevis and to the top of drawbar. Add additional 1” flatwashers (2) between the bottom of drawbar and bottom lip of clevis to fill open space. Insert a 3/4” x 4-1/2” grade 5 or 8 bolt (3) through clevis and drawbar and retain in position with a 1” locknut (4). The bolt and locknut should be tightened securely to support the tongue properly without springing of breaking the clevis. Never attach mower to the tractor with a pin not having a nut.

5. Securely attach mower safety chain from mower tongue to tractor drawbar or drawbar support frame.

6. Lower the jack until the tongue is completely supported by the drawbar. Remove jack from the tongue and place on storage bracket of mower main frame.

7. If using a hydraulic cylinder, connect hydraulic hose ends into tractor hydraulic ports. Pressure may need to be relieved from the system to allow for ease of attachment.

8. If the mower has been attached to a 3-point hitch drawbar, adjust any tractor equipped lower link check chains, guide blocks, or sway blocks to prevent the hitch and mower from swaying side to side.

NOTE: Never raise the 3-point lift with the mower attached as catastrophic driveline damage will occur.

6.3 Setting Mowing Height-Pull Type

1. Park the tractor and mower on level ground.

2. Using the tailwheel ratchet jack or hydraulic cylinder, position the mower so the skid shoes are 1” less off the ground than the desired final cut height. For example, if a 3” cut is desired, raise or lower the mower until the skid shoes are 2” off the ground. If a hydraulic cylinder is used, stroke control spacers can be placed on the hydraulic shaft to maintain a set cutting height each time the mower is raised and lowered.

3. Adjust the mower leveling rod so that the front of the mower is approximately 3/4” lower than the rear.

4. If the mower is attached to a 3-point hitch drawbar, adjust any tractor equipped lower link check chains, guide blocks, or sway blocks to prevent the hitch and mower from swaying from side to side. Never raise the 3-point lift with the mower attached as catastrophic driveline damage will occur.

260/272/284 01/11 Operation Section 4-15

OPERATION

6.4 Setting Deck Pitch

Lower Horse Power - Better Fuel Efficiency

To increase fuel efficiency and lower horsepower requirements for mower operation, the mower should be operated with the deck approximately 3/ 4" LOWER IN THE FRONT THAN THE REAR. Operating the mower at this pitch will allow the mower to cut the grass only once and requires less work from the tractor.

Increase Mulching

To increase mulching of the grass or crop material during mower operation, the mower should be operated with the deck approximately 3/4" HIGHER IN THE FRONT THAN THE REAR.

Operating the mower at this pitch will allow the mower to cut the grass twice and can result in a more even cut and improved distribution of the cut material.

IMPORTANT:

Adjust the leveling rods the same amount and maintain equal tension in the rods. Improper adjustment may cause rods to snap or bend. Retighten the jamnuts after the deck pitch has been set. OPS-U-0041

7. DRIVELINE ATTACHMENT

The driveline yoke and tractor PTO shaft must be dirt free and greased for attachment.

To connect the mower driveline to the tractor PTO output shaft, pull the driveline yoke collar back and align the grooves and splines of the yoke with those of the PTO shaft. Push the driveline yoke onto the PTO shaft, release the locking collar, and position the yoke until the locking collar balls are seated onto the PTO shaft. Push and pull the driveline back and forth several times to ensure a secure attachment. OPS-R-0003_A

OPERATION

260/272/284 01/11 Operation Section 4-16

OPERATION

When attaching the Implement input driveline to the Tractor PTO, it is important that the connecting yoke spring activated locking collar slides freely and the locking balls are seated securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth several times to ensure it is securely attached. A driveline not attached correctly to the Tractor PTO shaft could come loose and result in personal injury and damage to the Implement.

(S3PT-17)

Before operating the Implement, check to make sure the Implement input driveline will not bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and through the support bearings or downward onto the PTO shaft, breaking it off. A broken driveline can cause personal injury.

(S3PT-18)

“Bottoming Out” Check Procedure

• Disconnect driveline from the tractor and slide the profiles together until fully compressed.

• Place a mark on the inner shield 1/8” from the end of the outer shield.

• Reattach the driveline to the PTO Shaft.

• Raise the mower. Drive through a typical ditch which the unit may encounter and watch marks on the driveline. If the distance between the mark and the outer shield becomes less than 2” at any point there is a potential problem bottoming out the driveline and the driveline should be shortened. OPS-R-0004_F

7.1 Driveline Length Check

When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most compressed position, the profiles do not “bottom out”, and when at its farthest extended position, there is sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least a 1” clearance between each profile end and opposite profile universal joint. At its farthest operating extension, a minimum profile engagement of 9” must be maintained.

OPERATION

260/272/284 01/11 Operation Section 4-17

OPERATION

Shorten the driveline profiles as follows:

• Remove the driveline from the tractor.

• Raise and lower the mower to find the position

with the shortest distance between the tractor PTO shaft and cutter gearbox. Shut down the tractor and securely block the mower in this position.

• Pull driveline apart and reattach yoke to PTO

shaft.

• Hold driveline sections parallel to one another

and measure back 1” from yoke of each shaft and place mark on opposite section. Cut this length off with a saw.

• Round off all sharp edges and debur.

• Thoroughly grease then reinstall the driveline.

• Recheck for proper operation.

Engagement Check Procedure

• With the driveline attached, raise and lower the mower within its operating range. Position the mower to

the point where the telescoping driveline is at its maximum extension. Completely shut down the tractor and secure in position.

• Mark the inner driveline shield 1/8” from the end of the outer shield.

• Disconnect the driveline from the tractor and separate the two driveline halves.

• Measure the distance from the mark to the end of the inner profile. This length is the amount the driveline

profiles were engaged.

• If the engaged length is less than 9”, the shaft is considered too short and should be replaced with a longer

shaft. Consult an authorized dealer to purchase the required driveline length.

NOTE: When raising the mower, at least 1” clearance must be maintained between the driveline and the

8. PRE-OPERATION INSPECTION AND SERVICE

Before each use, a pre-operation inspection and service of the implement and tractor must be performed. This includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped and functional, and performing needed repairs. DO NOT operate the unit if the pre-operation inspection reveals any condition affecting safe operation. Perform repairs and replacement of damaged and missing parts as soon as noticed. By performing a thorough pre-operation inspection and service, valuable down time and repair cost can be avoided. OPS-U-0029

Always disconnect the main PTO Driveline from the Tractor before performing service on the Implement. Never work on the Implement with the tractor PTO driveline connected and running. Rotating Parts, Blades or Drivelines could turn without warning and cause immediate entanglement, injury or death.

OPERATION

Never run the Tractor engine in a closed building or without adequate ventilation. The exhaust fumes can be hazardous to your health.

(SG-23)

Transport only at speeds where you can maintain control of the equipment. Serious accidents and injuries can result from operating this

equipment at high speeds. Understand the Tractor and Implement and how it handles before transporting on streets and highways. Make sure the Tractor steering and brakes are in good condition and operate properly.

Before transporting the Tractor and Implement, determine the proper transport speeds for you and the equipment. Make sure you abide by the following rules:

Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly to determine the stopping characteristics of the Tractor and Implement. As you increase the speed of the Tractor the stopping distance increases. Determine the maximum transport speed not to exceed 20 mph (30 kph) for transporting this equipment.

Test the equipment at a slow speed in turns. Increase the speed through the turn only after you determine that the equipment can be operated at a higher speed. Use extreme care and reduce your speed when turning sharply to prevent the tractor and implement from turning over. Determine the maximum turning speed for you and this equipment before operating on roads or uneven ground.

Only transport the Tractor and Implement at the speeds which allow you to properly control the equipment.

Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance increases: use extreme care and reduce your speed. When operating in traffic always use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you and watch out for the other guy.

(SG-19)

9. DRIVING THE TRACTOR AND IMPLEMENT

Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the weight of the implement and the tractor operating controls are set for safe transport. To ensure safety while driving the tractor with an attached implement, review the following. OPS-U- 0012

OPERATION

260/272/284 01/11 Operation Section 4-29

OPERATION

9.1 Starting the Tractor

The procedure to start the tractor is model specific. Refer to the tractor operator’s manual for starting procedures for your particular tractor. Consult an authorized dealer if the starting procedure is unclear. Ensure the 3-point control lever is in the lowered position and the PTO is disengaged before starting the tractor. OPS-U-0033

9.2 Brake and Differential Lock Setting

Make sure the tractor brakes are in good operating condition. Tractor brakes can be set to operate independently allowing single rear wheel braking action or locked together to provide simultaneous rear wheel braking. FOR MOST DRIVING AND OPERATING CONDITIONS, THE BRAKE PEDALS SHOULD BE LOCKED TOGETHER TO PROVIDE THE MOST EFFECTIVE BRAKING ACTION.

Always disengage the tractor differential lock when turning. When engaged the differential lock will prevent or limit the tractor from turning. During normal cutting conditions, locking the differential provides no benefit and should not be used. OPS-

U- 0013

Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.

When operating down a hill or on wet or rain slick roads, the braking distance increases; use

extreme care and reduce your speed in these conditions. When operating in traffic, always

use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around

you and watch out for the other guy.

9.3 Raising the Mower

Using the tractor 3-point hitch control lever, raise the mower off the ground about 6”, or just high enough to clear any ground obstacles. When raising the mower, make sure all connection points are securely attached and at least 1” clearance is maintained between the driveline and the deck. If necessary, place an upper lift stop on the 3-point hitch control lever to limit the height the mower can

be raised to avoid driveline damage

. OPS-R-0042

9.4 Driving the Tractor and Mower

Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the tractor and mower. Moving slowly at first will also prevent the tractor from rearing up and loss of steering control. The tractor should never be operated at speeds that cannot be safely handled or which will prevent the operator from stopping quickly during an emergency. If the power steering or engine ceases operating, stop the tractor immediately as the tractor will be difficult to control.

Perform turns with the tractor and mower at slow speeds to determine how the tractor with an attached mower handles a turn. Determine the safe speed to maintain proper control of the tractor when making turns. When turning with a towed implement, the overall working length of the unit is increased. Allow additional clearance for the mower when turning.

To avoid overturns, drive the tractor with care and at safe speeds, especially when operating over rough ground, crossing ditches or slopes, and turning corners. Tractor wheel tread spacing should be increased when working on inclines or rough ground to reduce the possibility of tipping.

Use extreme caution when operating on steep slopes. Keep the tractor in a low gear when going downhill. DO NOT coast or free-wheel downhill.

OPS-R-0019

OPERATION

260/272/284 01/11 Operation Section 4-31

OPERATION

When confronted with an incline or ditch, do not approach from an angle which is perpendicular or straight on as damage to or over-collapse of the driveline may occur. OPS-R-0021_A

9.5 Crossing Ditches and Steep Inclines

When crossing ditches with steep banks or going up sharp inclines, it is possible that the main driveline inner profile will penetrate into the outer housing to its maximum depth until the assembly becomes solid (driveline is at its extreme shortest length). This type of abusive operation can cause serious damage to the tractor and mower drive by pushing the PTO into the tractor and through the support bearings or downward onto the PTO shaft, breaking it off.

Damage resulting from over-collapse of the driveline’s inner profile and its outer housing may allow the driveline to come loose from the Tractor which could cause bodily injury to the operator or bystanders and/or extensive damage to the Tractor or Implement. OPS-R-0020

OPERATION

260/272/284 01/11 Operation Section 4-32

OPERATION

Inclines and ditches should be approached along a line which is at an angle as shown. This type of path will reduce the possibility of over-collapse of the driveline and resulting damage. If the gradient is so steep that such an approach increases the possibility of a tractor roll-over, select an alternate crossing path.

When operating the tractor and mower across slopes and inclines, through ditches, and other uneven terrain conditions, it is important to maintain sufficient deck to ground clearance. Blade contact with the ground may cause soil, rocks and other debris to be thrown out from under the mower resulting in possible injury and/or property damage. Ground contact also produces a severe shock load on the mower drive and to the mower blades

resulting in possible damage and premature wear.

OPS-R-0022

10. OPERATING THE TRACTOR AND IMPLEMENT

THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and

understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These manuals must be read and explained to any operator who cannot read. Never allow someone to operate the implement and tractor without complete operating instructions.

Before starting any operation, the operator must become familiar with the area to be worked in and any obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.

OPS-U- 0015

Extreme care should be taken when operating near loose objects such

as gravel, rocks, wire, and other debris. Inspect the area before

mowing. Foreign objects should be removed from the site to prevent

machine damage and/or bodily injury or even death. Any objects that

cannot be removed must be clearly marked and carefully avoided by the

operator. Stop mowing immediately if blades strike a foreign object.

Repair all damage and make certain rotor or blade carrier is balanced

before resuming mowing.

(SGM-05)

OPERATION

260/272/284 01/11 Operation Section 4-33

OPERATION

Many varied objects, such as wire, cable, rope, or chains, can become entangled in the

operating parts of the mower head. These items could then swing outside the housing at

greater velocities than the blades. Such a situation is extremely hazardous and could result

in serious injury or even death. Inspect the cutting area for such objects before mowing.

Remove any like object from the site. Never allow the cutting blades to contact such items.

(SGM-06)

10.1 Foreign Debris Hazards

Before mowing, inspect the area to make sure there are no foreign objects that the mower blades could hit or become entangled with. Remove all foreign objects and debris. If objects are too big to remove, mark them clearly and be sure to prevent the mower blades from contacting them.

If you hit a solid object or foreign debris, stop the mower and tractor at once. Immediately idle the engine speed and disengage the PTO. Wait for all mower rotating motion to stop, then raise the mower and move the tractor and implement off the object. Inspect the area and remove, or mark the location of the debris. Inspect the condition of the mower and make any needed repairs immediately. Make sure the blades are not damaged and the carrier is balanced before resuming operation.

Always wear your seat belt securely fastened and only operate the tractor and mower with the ROPS in the raised position. If the tractor or mower hits a tree stump, rock, or bump, a sudden movement could throw you off of the seat and under the tractor and/or mower. The seat belt is your best protection from falling off the tractor and the ROPS provides protection from being crushed during a tractor roll-over. OPS-R-0023

Remove Foreign Material

Raise Mower over solid objects

10.2 Bystanders/Passersby Precautions

If a bystander comes within 300 feet of the tractor while the mower is being operated, stop the tractor at once, idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past the 300 foot distance. OPS-R-0024

OPERATION

260/272/284 01/11 Operation Section 4-34

OPERATION

Rotary Mowers are capable under adverse conditions of throwing objects for great distances (300 feet or more) and causing serious injury or death. Follow safety messages carefully.

STOP MOWING IF PASSERSBY ARE WITHIN 300 Feet UNLESS:

-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition;

-Mower sections or Wings are running close to and parallel to the ground without exposed Blades;

-Passersby are outside the existing thrown-object zone;

-All areas have been thoroughly inspected and all foreign material such as rocks, cans, glass, and general debris has been removed.

NOTE: Where there are grass and weeds high enough to hide debris that could be struck by the blades, the area should be: inspected and large debris removed, mowed at an intermediate height, inspected, closely with any remaining debris being removed, and mowed again at desired final height. (This will also reduce power required to mow, reduce wear and tear on the Mower drivetrain, spread cut material better, reduce streaking, and make the final cut more uniform).

(SRM-01)

10.3 Engaging the Power Take Off (PTO)

Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement must be completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with the implement in the raised position.

Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to the on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the implement to determine the cause of the noise or vibration and repair the abnormality. OPS-U- 0027

Do not let the Blades turn when the Mower Deck is raised for any

reason, including clearance or for turning. Raising the Mower deck

exposes the Cutting Blades which creates a potentially serious hazard

and could cause serious injury or even death from objects thrown from

the Blades.

(SRM-07)

Do not put hands or feet under mower decks. Blade Contact can result

in serious injury or even death. Stay away until all motion has stopped

and the decks are securely blocked up.

(SGM-09)

OPERATION

260/272/284 01/11 Operation Section 4-35

OPERATION

10.4 PTO RPM and Ground Speed

Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Recommended speed for efficient mower performance is between 2 and 5 mph(3-8 kph). Operate the mower at its full rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or the tractor instrument panel for the engine speed and gear to provide the required PTO and desired ground speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut. If it becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually.

Ground speed is achieved by transmission gear selection and not by the engine operating speed. The operator may be required to experiment with several gear range combinations to determine the best gear and range which provides the most ideal performance from the mower and most efficient tractor operation. As the severity of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to maintain the proper operating PTO speed. OPS-R-0025

Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause

Implement driveline or blade failures resulting in serious injury or death.

(SG-26)

Mow at the speed that you can safely operate and control the tractor and mower. The

correct mowing speed depends on terrain condition and grass type, density, and height of

cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds

when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power

lines, or when debris and foreign objects are to be avoided.

(SGM-07)

10.5 Operating the Mower

Only operate the mower from the tractor operator’s seat with the seatbelt securely fastened. The tractor must be equipped with a ROPS in the raised position or a ROPS cab.

The mower is designed to cut vegetation up to 2-1/2” in diameter. Sharp blades will produce a cleaner cut and require less power. Travel at a speed that allows the mower sufficient time to cut through the vegetation and maintain the PTO operating speed to prevent overloading the mower and tractor. Choose a driving pattern that provides the maximum pass length and minimizes turning.

Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the same height as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining the operating speed of the mower. A slower ground speed will permit grasses to at least partially rebound and be cut. Taking a partial cut and/or reversing the direction of travel may also help produce a cleaner cut.

Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to access areas to be cut, make sure there are no persons or other foreign debris behind the mower before mowing in reverse. When mowing in reverse, operate the tractor and mower at a reduced ground speed to ensure tractor and mower control is maintained. OPS-R-0026_F

Do not mow with two machines in the same area except with Cab tractors with the windows

closed.

OPERATION

Mow only in conditions where you have clear visibility in daylight or with adequate artificial lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least 300 feet (90 m) in front and to the sides of the tractor and mower. Make sure that you can clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions, power lines, debris and foreign objects. If you are unable to clearly see these type of items discontinue mowing.

(SGM-1)

Avoid mowing in reverse direction when possible. Check to make sure there are no

persons behind the mower and use extreme care when mowing in reverse. Mow only at a

slow ground speed where you can safely operate and control the tractor and mower.

Never mow an area that you have not inspected and removed debris or foreign material.

(SGM-08)

Follow these guidelines to reduce the risk of equipment and grass fires while operating, servicing, and repairing the Mower and Tractor:

-Equip the Tractor with a fire extinguisher in an accesible location.

-Do Not operate the Mower on a Tractor with an underframe exhaust.

-Do Not smoke or have an open flame near the Mower and Tractor.

-Do Not drive into burning debris or freshly burnt areas.

-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.

-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes. Periodically shut down the Tractor and Mower and clean clippings and collected debris from the mower deck.

(SGM-12)

When you get to the end of a pass, slightly raise the mower (2-4”) before turning. Never raise the mower entirely while the blades are turning. If the mower must be raised higher than 12” from ground level, disengage the tractor PTO and wait for all mower rotation to come to a complete stop before proceeding to raise the mower. OPS-R-0027_B

12. MOWER STORAGE

Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance and to help ensure years of dependable service. The following are suggested storage procedures:

• Thoroughly clean all debris off the mower to prevent damage from rotting grass and standing water.

• Lubricate all mower grease points and fill gearbox oil levels as detailed in the maintenance section.

• Tighten all bolts and pins to the recommended torque.

• Check the mower for worn and damaged parts. Perform repairs and make replacements immediately so that the mower will be ready for use at the start of the next season.

• Store the mower in a clean, dry place with the mower housing resting securely on blocks or at ground level.

• Keep the driveline yoke from sitting in water, dirt and other contaminants.

• Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the mower.

It is critical that driveline clutches slip when an obstacle or heavy load is encountered to avoid mower and/or tractor damage. If the mower sits outside for an extended period of time or is exposed to rain and/or humid air, the clutch lining plates must be inspected to ensure they are not frozen together from rust or corrosion. If the mower has been exposed to such conditions, at the start of each mowing season, and any time it is suspected that the slip clutch plates may be frozen together, readjust the slip clutch as detailed in Seasonal Clutch Maintenance of the maintenance section in this manual. OPS-R-0032_A

Never allow children or other persons to ride on the Tractor or Implement. Falling off can result in serious injury or death.

13. TRANSPORTING THE TRACTOR AND IMPLEMENT

Inherent hazards of operating the tractor and implement and the possibility of accidents are not left behind when you finish working in an area. Therefore, the operator must employ good judgement and safe operation practices when transporting the tractor and implement between locations. By using good judgement and following safe transport procedures, the possibility of accidents while moving between locations can be substantially minimized. OPS-U- 0017

OPERATION

260/272/284 01/11 Operation Section 4-42

OPERATION

Before transporting the tractor and mower, idle the tractor engine, disengage the PTO and wait for all mower moving parts to come to a complete stop. Once all mower parts are completely stopped, raise the mower to transport height. NOTE: When

raising the mower, maintain 1” clearance between the driveline and mower deck. If additional mower deck height is needed for safe transport, disconnect the driveline from the tractor and secure its end to the mower deck. The mower can then be raised to the maximum lift height. OPS-R-0033_A

If the tractor’s hydraulic pump is not independent of the tractor PTO, or if the tractor PTO has to be run to have hydraulic power, disconnect the mower driveline from the tractor PTO output shaft. Secure the driveline to the mower deck to prevent driveline damage or loss during transport. OPS-R-0034

13.1 Transporting on Public Roadways

Extreme caution should be used when transporting the tractor and implement on public roadways. The tractor must be equipped with all required safety warning features including a SMV emblem and flashing warning lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them. Check your side view mirrors frequently and remember that vehicles will approach quickly because of the tractor’s slower speed. Be extremely cautious when the piece of equipment that you are towing is wider than the tractor tire width and/or extends beyond your lane of the road.

Make sure that a proper size safety tow chain is secured between the tractor and implement before entering a public road. OPS-U- 0019

Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in such a way as to be clearly visible and legible. When transporting the Equipment use the Tractor flashing warning lights and follow all local traffic regulations.

(SG-6)

OPERATION

260/272/284 01/11 Operation Section 4-43

OPERATION

The SMV (Slow-Moving Vehicle) emblem is universal symbol used to alert drivers of the presence of equipment traveling on roadways at a slow speed. SMV signs are a triangular bright orange with reflective red trim for both easy day and night visibility. Make sure the SMV sign is clean and visible from the rear of the unit before transporting the tractor and implement on a public roadway. Replace the SMV emblem if faded, damaged, or no longer reflective. OPS-U- 0020

Make sure that all tractor flashing warning lights, headlights, and brake/tail lights are functioning properly before proceeding onto public roads. While newer model tractors have plenty of lighting to provide warning signals and operating lighting, most older models are only equipped with operating lights. Consult an authorized tractor dealer for lighting kits and modifications available to upgrade the lighting on older tractor models. OPS-U- 0021

When operating on public roads, have consideration for other road users. Pull to the side of the road occasionally to allow all following traffic to pass. Do not exceed the legal speed limit set in your country for agricultural tractors. Always stay alert when transporting the tractor and implement on public roads. Use caution and reduce speed if other vehicles or pedestrians are in the area. OPS-

U- 0022

OPERATION

260/272/284 01/11 Operation Section 4-44

OPERATION

Reduce speed before turning or applying the brakes. Ensure that both brake pedals are locked together when operating on public roads. OPS-U- 0023

13.2 Hauling the Tractor and Implement

Before transporting a loaded tractor and implement, measure the height and width dimensions and gross weight of the complete loaded unit. Ensure that the load will be in compliance with the legal limits set for the areas that will be traveled through

Use adequately sized and rated trailers and equipment to transport the tractor and implement. Consult an authorized dealer to determine the proper equipment required. Using adequately sized chains, heavy duty straps, cables and/or binders, securely tie down both the front and rear of the tractor utilizing the proper tie down locations as specified by the tractor manufacturer.

Arrange the chains so that when tightened, the chains are pulling downward and against themselves. Carefully tighten the securing chains or other fasteners using boomers or binders to apply maximum tension. Use extreme care when attaching and removing the securing devices as the extreme tension involved when released has the potential to inflict serious injury.

While hauling the tractor and implement, make occasional stops to check that the tractor and implement have not moved or shifted and that the securing chains have maintained tension. If during transport a hard braking, sharp turning, or swerving action was performed, stop at the next safe location to inspect the security of the load.
