In order to reduce accidents and enhance the safe operation of mowers, Alamo Industrial, 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 be educated in the operation of their 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 Alamo Industrial 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 Indus- trial.

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.

Operator Safety Instructions and Practices

The rotating parts of this machine continue to rotate even after the PTO has been turned off. The operator should remain in his seat for 60 seconds after the brake has been set, the

PTO disengaged, the tractor turned off, and all evidence of rotation has ceased.

Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch. Release of the control lever or mechanical failure will result in the Implement falling and possible injury or death. Always securely block up the Implement before crawling underneath to perform repairs and service.

you have read an completely understand this Manual, the Tractor Operator’s Manual, and each of the Safety Messages found in the Manual or on the Tractor and Implement. Learn how to stop the tractor engine suddenly in an emergency. Never allow inexperienced or untrained personnel to operate the Tractor and Implement without supervision. Make sure the operator has fully read and understood the manuals prior to operation.

(SG-4)

The operator and all support personnel should wear hard hats, safety shoes, safety glasses, and proper hearing protection at all times for protection from injury including injury from items that may be thrown by the equipment.

(SG-16)

PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PERMANENT HEARING LOSS! Tractors with or without an Implement attached can often be noisy enough to cause permanent hearing loss. We recommend that you always wear hearing protection if the noise in the Operator’s position exceeds 80db. Noise over 85db over an extended period of time will cause severe hearing loss. Noise over 90db adjacent to the Operator over an extended period of time will cause permanent or total hearing loss. NOTE: Hearing loss from loud noise

[from tractors, chain saws, radios, and other such sources close to the ear] is cumulative over a lifetime without hope of natural recovery.

Equipment Operation Safety Instructions and Practices

Never leave the Tractor and Implement unattended while the Implement is in the lifted position. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop

of unit with injury or death by crushing. To properly park the implement when disconnecting it from the tractor, lower the stand and put the retaining pin securely in place, or put a secure support under the A-Frame. Lower the implement carefully to the ground. Do not put hands or feet under lifted components.

se extreme care when lowering or unfo

ng the implement’s wings. Make sure no bystanders are close by or underneath the wings. Allow ample clearance around the implement when folding or unfolding the wings. Use extreme caution around buildings or overhead power lines.

(S3PT-5)

This Implement is wider than the Tractor. Be careful when operating or transporting this equipment to prevent the Implement from running into or striking sign posts, guard rails, concrete abutments or other solid objects. Such an impact could cause the Implement and Tractor to pivot violently resulting in loss of steering control, serious injury, or even death. Never allow the Implement to contact obstacles.

(SBH-6)

Do not operate Mower if excessive vibration exists. Shut down PTO and the Tractor

engine. Inspect the Mower to determine the source of the vibration. If Mower blades are missing or damaged replace them immediately. Do not operate the mower until the blades have been replaced and the Mower operates smoothly. Operating the Mower with excessive vibration can result in component failure and broken objects to be thrown outward at very high velocities. To reduce the possibility of property damage, serious injury, or even death, never allow the Mower to be operated with blades missing.

even death could result from falling off the tractor--particularly during a turnover

when the operator could be pinned under the ROPS.

(SG-7)

BEFORE leaving the tractor seat, always engage the brake and/or set

the tractor transmission in parking gear, disengage the PTO, stop the

engine, remove the key, and wait for all moving parts to stop. Place the

tractor shift lever into a low range or parking gear to prevent the tractor

from rolling. Never dismount a Tractor that is moving or while the engine

is running. Operate the Tractor controls from the tractor seat only.

(SG-9)

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

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.

Do not mount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completely stopped.

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 100 yards(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.

There are obvious and hidden potential hazards in the operation of this

Mower. REMEMBER! This machine is often operated in heavy brush and in heavy weeds. The Blades of this Mower can throw objects if shields are not properly installed and maintained. Serious injury or even death may occur unless care is taken to insure the safety of the operator, bystanders, or passersby in the area. Do not operate this machine with anyone in the immediate area. Stop mowing if anyone is within 100 yards of mower.

(SGM-2)

(SGM-1)

SAFETY

The rotating parts of this machine have been designed and tested for rugged use. However, the blades could fail upon impact with heavy, solid objects such as metal guard rails and concrete structures. Such impact could cause the broken objects to be thrown outward at very high velocities. To reduce the possibility of property damage, serious injury, or even death, never allow the cutting blades to contact such obstacles.

(SGM-4)

reme care should be taken when operating near loose objects suc

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-5)

any 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-6)

ow 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.

The M

ifi

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-8)

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

closed.

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.

(SGM-11)

SAFETY

-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)

ower is designed for certain mowing applications and is rated to cut up to a spec

size vegetation (see Mower Standard Equipment and Specifications). DO NOT use this mower to cut vegetation above the Mower’s rated capacity or to cut any type of non-vegetative material. Only operate this Mower on a properly sized and equipped Tractor. Operating this Mower in an application for which it is not designed and/or operating the Mower with the wrong size Tractor can cause Mower component damage and equipment failure resulting in possible serious injury or death.

(SGM-14)

Do not operate or pull the mower into standing water. When uplift or fan type mower blades contact water they can be severely deflected downward causing possible failure of blade

resulting in serious boldly injury to the operator or bystanders.

(SGM-15)

Use extreme caution when raising the Mower above ground level. Stop the Blades from

turning when the Mower is raised and passersby are within 100 yards. Raising the Mower exposes the Cutting Blades which creates a potentially serious hazard and can cause serious injury by objects thrown from the Blades or by contact with the Blades.

(SPU-1)

A60/A72 01/08 Safety Section 1-9

Page 16

SAFETY

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 100 YARDS 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

SAFETY

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-1)

Do Not attempt to raise or lower the implement wing unless the Implement tongue is securely attached to the Tractor drawbar. The Implement could tip over and cause equipment damage and possible serious injury or death. Raise or Lower the mower wing only while seated in the Tractor operator’s seat with the seat belt securely fastened.

Do not turn so sharp or lift mower so high to produce a severe "knocking" of the Driveline

which will cause accelerated wear and breakage of drive train components and could result in possible injury from the separated Driveline sections.

(SRM-4)

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-7)

Connecting or Disconnecting Implement Safety Instructions and Practices

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.

Always shut the Tractor completely down, place the transmission in park, and set the

parking brake before you or anyone else attempts to connect or disconnect the Implement

and Tractor hitches.

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.

mportant 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. 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)

Transporting Safety Instructions and Practices

Be particularly careful when transporting the Implement with the Tractor. Turn curves or go

up hills only at a low speed and using a gradual steering angle. Rear mounted implements move the center of gravity to the rear and remove weight from the front wheels. Make certain, by adding fron ballast, that at least 20% of the tractor’s weight is on the front wheels to prevent rearing up, loss of steering control or Tractor tip-over. Slow down on rough or uneven surfaces to prevent loss of steering control which could result in property damage or possible injury. Do not transport unless 3-Point lift lever is fully raised and in the latched transport position. Dropping implement in transport can cause serious damage to the tracto and/or Implement and possibly cause the operator or others to be injured or killed. (S3PT-2)

Allow sufficient clearance for the Implement to swing outward while turning. Implements

carried behind the Tractor will swing outside the tire path when making turns. Contacting a

solid object while turning will cause equipment damage and possible injury.

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.

SAFETY

Only t

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

SAFETY

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)

Be particularly careful when transporting the Implement using the tractor. Turn curves or

go up or down hills only at a low speed and at a gradual steering angle. Make certain that

at least 20% of the tractor’s weight is on the front wheels to maintain safe steerage. Slow

down on rough or uneven surfaces.

ransport the Implement behind a properly sized and equippe Tractor which exceeds the weight of the Implement by at least 20%. DO NOT transport the Implement behind a truck or other type of vehicle. Never transport the Implement and another Implement connected in tandem. Never transport the Implement at speeds over 20 MPH.

INTRODUCTION

These mowers are available in lift-type models only. These rugged Mowers are designed for heavy-duty work. They can mow pastures, cut brush up to 3" in diameter, and control grass and weeds on highways or industrial sites.

For Non-Agricultural use, OSHA, ASAE, SAE, and ANSI standards require the use of Chain Guards or Solid Skirts at all times. The Cutter manufacturer strongly recommends the use of Chain Guards or Solid Skirts for Agricultural purposes as well, to reduce the risk of property damage, serious bodily injury, or even death from objects thrown out by or from contact with the Cutting Blades.

The A60 requires a tractor with a minimum of 30 HP and the A72 requires a minimum of 40 HP with adequate front end weight.

At least 20% or the tractor’s weight must be on the front tires with the implement lifted to provide adequate traction for safe steering under good conditions. Slow down on hills, rough terrain, and curves.

Front and rear, and left and right are determined by the normal direction of travel (the same as on your automobile).

A60/A72 01/08 Operation Section 4-5

Page 92

OPERATION

4. Tractor Horsepower

The horsepower required to operate the mower depends on several operating factors including the vegetation to be cut, terrain condition, operator experience, condition of the mower and tractor, and others. For most mowing conditions, the A60 mower requires a tractor with a minimum of 30 HP and the A72 mower requires a tractor with a minimum of 40 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine. Exceeding 75 HP may cause mower damage by overpowering the unit in heavy cutting conditions.

4.1 3-Point Hitch

The tractor 3-point hitch must be rated to lift at least 850 lbs. if attaching an A60 and 1050 lbs. if attaching an A72 mower..

A60/72 mowers can attach to tractor’s with either a CAT I or II hitch. Refer to the tractor operator’s manual for the category of the tractor used. If the hitch does not conform to ASAE Cat I or II

OPERATION

dimensions, the mower may not fit or raise properly. Consult an authorized dealer for possible modification procedures to mount nonconforming hitches.

Use the correct hitch pins for the hitch category being used. For a Cat I hitch, 7/8” lower and 3/4” upper diameter hitch pins are used and Cat II hitches require 1-1/8” lower and 1” upper diameter hitch pins.

4.2 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

A60/A72 01/08 Operation Section 4-6

Page 93

OPERATION

4.3 Power Take Off (PTO)

Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. 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 or a 1-3/4” 20 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-U- 0006

(S3PT-14)

OPERATION

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)

5. 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 the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completely stopped.

(SG-12)

A60/A72 01/08 Operation Section 4-7

Page 94

OPERATION

5.1 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

(SG-11)

OPERATION

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

(SG-10)

5.2 Dismounting the Tractor

Before dismounting, park the tractor and implement on a reasonably level surface, apply the parking brake, idle the engine down, disengage the PTO, and lower the implement to the ground. Shut down the tractor engine according to the operator’s manual, remove the key, and wait for all motion to completely stop. Never leave the seat until the tractor, its engine and all moving parts have come to a complete stop.

Use hand rails and steps when exiting the tractor. Be careful of your step and use extra caution when mud, ice, snow or other matter has accumulated on the steps or hand rails. Use all handrails and steps for support and never rush or jump off the tractor. OPS-U- 0009

BEFORE leaving the tractor seat, always engage the brake and/or set the tractor transmission in parking gear, disengage the PTO, stop the engine, remove the key, and wait for all moving parts to stop. Place the tractor shift lever into a low range or parking gear to prevent the tractor from rolling. Never dismount a Tractor that is moving or while the engine is running. Operate the Tractor controls from the tractor seat only.

(SG-9)

A60/A72 01/08 Operation Section 4-8

Page 95

OPERATION

6. STARTING THE TRACTOR

The operator must have a complete understanding of the placement, function, and operational use of all tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized dealer for tractor operation instructions if needed.

Essential Tractor Controls:

• Locate the light control lever.

• Locate the engine shut off control.

• Locate the brake pedals and the clutch.

• Locate the PTO control.

• Locate the 3-point hitch control lever.

• Locate the hydraulic remote control levers. Before starting the tractor ensure the following:

• Conduct all pre-start operation inspection and service according to the tractor operator’s manual.

• Make sure all guards, shields, and other safety devices are securely in place.

• The parking brake is on.

• The PTO control lever is disengaged.

• The 3-point hitch control lever is in the lowered position.

• The hydraulic remote control levers are in the neutral position.

• The tractor transmission levers are in park or neutral. Refer to the tractor owner’s manual for tractor starting procedures. Only start the tractor while seated and belted in the tractor operator’s seat. Never bypass the ignition switch by short circuiting the starter solenoid.

OPERATION

After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden and unexpected tractor movement. OPS-U-0028

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

Start tractor only when properly seated in the Tractor seat. Starting a tractor in gear can result in injury or death. Read the Tractor operators manual for proper starting instructions.

(SG-13)

(SG-23)

7. CONNECTING THE MOWER TO THE TRACTOR

Use extreme caution when connecting the mower to the tractor. The mower should be securely resting at ground level or setting on blocks. Keep hands and feet from under the mower deck and clear of pinch points between the tractor hitch arms and mower pins. OPS-R-0001

A60/A72 01/08 Operation Section 4-9

Page 96

Always shut the Tractor completely down, place the transmission in park, and set the parking brake before you or anyone else attempts to connect or disconnect the Implement and Tractor hitches.

1. Make sure the tractor is equipped with the correct PTO shaft. Change shafts if needed.

2. Shorten or remove the tractor drawbar to avoid interference when raising and lowering the mower.

3. Board the tractor and start the engine. Position the tractor to the mower with the 3-point lift arms positioned between the respective set of mower A-frame lift lugs.

4. Turn off the tractor engine and dismount.

5. One lift arm at a time, align arm end hole between the set of holes of A-frame lift lugs.

OPERATION

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 lift lugs.

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.

(S3PT-15)

OPERATION

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.

8. 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

A60/A72 01/08 Operation Section 4-10

Page 97

OPERATION

8.1 Setting Mower Height

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. Level the mower deck front to rear by extending or retracting the 3-point top link.

(SG-14)

OPERATION

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.

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.

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.

ng Deck

To facilitate safe and efficient operation, the mower should be operated with the deck approximately 3/4” LOWER IN THE FRONT THAN THE REAR. The correct deck pitch is obtained as follows:

1. Lower the mower until the rear of the mower is resting securely on its tail wheel.

2. Then slowly lower the 3-point lift arms further until the front of the mower is at least 3/4” lower than the rear of the mower.

3. Place the tractor’s 3-point control lever stop at this position so that each time the mower is raised and lowered the deck pitch will be maintained.

Operating the mower with the front of the deck slightly lower than the rear allows the mower to cut the grass only once and requires less work from the tractor. In addition, a more even distribution of the clippings from the rear of the mower will be achieved with this

OPERATION

angle. OPS-R-0002_B

9. 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

en attaching the Implement input driveline to the Tractor connecting yoke spring activated locking collar slides freely and the locking balls are seated securely in the groove on the Tractor PTO shaft. A driveline not attached correctly to the Tractor PTO shaft could come loose and result in personal injury and damage to the Implement.

9.1 Driveline Length Check

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)

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.

ng 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 and watch the driveline as it

approaches the mark. If the distance between the mark and the end of the outer shield tube becomes less than 2” at any point, the driveline must be shortened. OPS-R-0004_A

OPERATION

A60/A72 01/08 Operation Section 4-13

Page 100

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

OPERATION

• 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 mower deck. If necessary, place an upper lift stop on the 3-point hitch control lever to limit the height the mower can be raised. OPS-R-0005_E

10. 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.
