Important Safety Information

Listed below are common practices that may or may not be applicable to the products described in this manual.

Safety at All Times

Careful operation is your best assurance against an accident.

All operators, no matter how much experience they may have, should carefully read this manual and other related manuals, or have the manuals read to them, before operating the power machine and this implement.

 Thoroughly read and understand

the “Safety Label” section. Read

all instructions noted on them.

 Do not operate the equipment

while under the influence of drugs

or alcohol as they impair the ability

to safely and properly operate the

equipment.

 The operator should be familiar

with all functions of the tractor and

attached implement and be able to

handle emergencies quickly.

 Make sure all guards and shields

appropriate for the operation are in

place and secured before

operating implement.

 Keep all bystanders away from

equipment and work area.

 Start tractor from the driver’s seat

with hydraulic controls in neutral.

 Operate tractor and controls from

the driver’s seat only.

 Never dismount from a moving

tractor or leave tractor unattended

with engine running.

 Do not allow anyone to stand

between tractor and implement

while backing up to implement.

 Keep hands, feet, and clothing

away from power-driven parts.

 While transporting and operating

equipment, watch out for objects

overhead and along side such as

fences, trees, buildings, wires, etc.

 Do not turn tractor so tight as to

cause hitched implement to ride

up on the tractor’s rear wheel.

 Store implement in an area where

children normally do not play.

When needed, secure attachment

against falling with support blocks.

Look for the Safety Alert Symbol

The SAFETY ALERT SYMBOL indicates there is a potential hazard to personal safety involved and extra safety precaution must be taken. When you see this

Be Aware of Signal Words

A signal word designates a degree or level of hazard seriousness. The signal words are:

DANGER

Indicates a hazardous situation that, if not avoided, will result in death or serious injury.

Safety Precautions for Children

Tragedy can occur if the operator is not alert to the presence of children. Children generally are attracted to implements and their work.

 Never assume children will remain

where you last saw them.

 Keep children out of the work area

and under the watchful eye of a responsible adult.

 Be alert and shut the implement

and tractor down if children enter the work area.

 Never carry children on the tractor

or implement. There is not a safe place for them to ride. They may fall off and be run over or interfere with the control of the power machine.

 Never allow children to operate the

power machine, even under adult supervision.

 Never allow children to play on the

power machine or implement.

 Use extra caution when backing

up. Before the tractor starts to move, look down and behind to make sure the area is clear.

symbol, be alert and carefully read the message that follows it. In addition to design and configuration of equipment, hazard control, and accident prevention are dependent upon the awareness, concern, prudence, and proper training of personnel involved in the operation, transport, maintenance, and storage of equipment.

WARNING

Important Safety Information

Listed below are common practices that may or may not be applicable to the products described in this manual.

Tire Safety

 Tire changing can be dangerous

and must be performed by trained personnel using the correct tools and equipment.

 Always maintain correct tire

pressure. Do not inflate tires above recommended pressures shown in the Operator’s Manual.

 When inflating tires, use a clip-on

chuck and extension hose long enough to allow you to stand to one side and NOT in front of or over the tire assembly. Use a safety cage if available.

 Securely support the implement

when changing a wheel.

 When removing and installing

wheels, use wheel handling equipment adequate for the weight involved.

 Make sure wheel bolts have been

tightened to the specified torque.

Transport Safely

 Comply with federal, state, and

local laws.

 Use towing vehicle and trailer of

adequate size and capacity. Secure equipment towed on a trailer with tie downs and chains.

 Sudden braking can cause a towed

trailer to swerve and upset. Reduce speed if towed trailer is not equipped with brakes.

 Avoid contact with any overhead

utility lines or electrically charged conductors.

 Always drive with load on end of

loader arms low to the ground.

 Always drive straight up and down

steep inclines with heavy end of a tractor with loader attachment on the “uphill” side.

 Engage park brake when stopped

on an incline.

 Maximum transport speed for an

attached equipment is 20 mph. DO NOT EXCEED. Never travel at a speed which does not allow adequate control of steering and stopping. Some rough terrains require a slower speed.

 As a guideline, use the following

maximum speed weight ratios for attached equipment:

20 mph when weight of attached equipment is less than or equal to the weight of machine towing the equipment.

10 mph when weight of attached equipment exceeds weight of machine towing equipment but not more than double the weight.

 IMPORTANT: Do not tow a load

that is more than double the weight of the vehicle towing the load.

Use A Safety Chain

 A safety chain will help control

drawn machinery should it separate from the tractor drawbar.

 Use a chain with the strength

rating equal to or greater than the gross weight of the towed implement.

 Attach the chain to the tractor

drawbar support or other specified anchor location. Allow only enough slack in the chain to permit turning.

 Always hitch the implement to the

machine towing it. Do not use the safety chain tow the implement.

Practice Safe Maintenance

 Understand procedure before doing

work. Refer to the Operator’s Manual for additional information.

 Work on a level surface in a clean

dry area that is well-lit.

 Lower implement to the ground and

follow all shutdown procedures before leaving the operator’s seat to perform maintenance.

 Do not work under any hydraulic

supported equipment. It can settle, suddenly leak down, or be lowered accidentally. If it is necessary to work under the equipment, securely support it with stands or suitable blocking beforehand.

 Use properly grounded electrical

outlets and tools.

 Use correct tools and equipment for

the job that are in good condition.

 Allow equipment to cool before

working on it.

 Disconnect battery ground cable (-)

before servicing or adjusting electrical systems or before welding on implement.

 Inspect all parts. Make certain

parts are in good condition & installed properly.

 Replace parts on this implement

with genuine Land Pride parts only. Do not alter this implement in a way which will adversely affect its performance.

 Do not grease or oil implement

while it is in operation.

 Remove buildup of grease, oil, or

debris.

 Always make sure any material and

waste products from the repair and maintenance of the implement are properly collected and disposed.

 Remove all tools and unused parts

before operation.

 Do not weld or torch on galvanized

metal as it will release toxic fumes.

Important Safety Information

Listed below are common practices that may or may not be applicable to the products described in this manual.

Prepare for Emergencies

 Be prepared if a fire starts.  Keep a first aid kit and fire

extinguisher handy.

 Keep emergency numbers for

doctor, ambulance, hospital, and fire department near phone.

911

Use Safety Lights and Devices

 Slow moving tractors, skid steers,

self-propelled machines, and towed equipment can create a hazard when driven on public roads. They are difficult to see, especially at night. Use the Slow Moving Vehicle sign (SMV) when on public roads.

 Flashing warning lights and turn

signals are recommended whenever driving on public roads.

Avoid Underground Utilities

 Dig Safe, Call 811 (USA).

Always contact your local utility companies (electrical, telephone, gas, water, sewer, and others) before digging so that they may mark the location of any underground services in the area.

 Be sure to ask how close you can

work to the marks they positioned.

Wear Personal Protective Equipment (PPE)

 Wear protective clothing and

equipment appropriate for the job such as safety shoes, safety glasses, hard hat, and ear plugs.

 Clothing should fit snug without

fringes and pull strings to avoid entanglement with moving parts.

 Prolonged exposure to loud noise

can cause hearing impairment or hearing loss. Wear suitable hearing protection such as earmuffs or earplugs.

 Operating equipment safely

requires the operator’s full attention. Avoid wearing headphones while operating equipment.

Use Seat Belt and ROPS

 Land Pride recommends the use

of a CAB or roll-over-protectivestructures (ROPS) and seat belt in almost all power machines. Combination of a CAB or ROPS and seat belt will reduce the risk of serious injury or death if the power machine should be upset.

 If ROPS is in the locked-up

position, fasten seat belt snugly and securely to help protect against serious injury or death from falling and machine overturn.

Avoid High Pressure Fluids Hazard

 Escaping fluid under pressure can

penetrate the skin causing serious injury.

 Before disconnecting hydraulic

lines or performing work on the hydraulic system, be sure to release all residual pressure.

 Make sure all hydraulic fluid

connections are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system.

 Use a piece of paper or

cardboard, NOT BODY PARTS, to check for suspected leaks.

 Wear protective gloves and safety

glasses or goggles when working with hydraulic systems.

 DO NOT DELAY. If an accident

occurs, see a doctor familiar with this type of injury immediately. Any fluid injected into the skin or eyes must be treated within a few hours or gangrene may result.

Keep Riders Off Machinery

 Never carry riders on tractor or

implement.

 Riders obstruct operator’s view

and interfere with the control of the power machine.

 Riders can be struck by objects or

thrown from the equipment.

 Never use tractor or implement to

lift or transport riders.

To avoid serious injury or death:

• Do not use a tractor that is too small or too large. Small

tractors can be pushed around and flipped over. Large tractors can damage the attached implement.

• Do not use a power take-off adapter. The adapter will

increase strain on the tractor’s power take-off shaft causing possible damage to shaft and driveline. It will also defeat the purpose of the tractor’s power take-off shield.

• Power take-off damage may occur if distances “A” and

“B” are not properly maintained.

Hydraulic Set-up

The number of tractor hydraulic duplex outlets is dependent upon how the Rotary Cutter is set-up.

• Two duplex outlets are required if the wings are raised

and lowered simultaneously. (Factory standard)

• Three duplex outlets are required if the wings are

raised and lowered independently. (Requires “Hydraulic Wing Control Kit” on page 38 to raise wings independently.)

• If the tractor does not have the necessary number of

duplex outlets, there are control valve kits available to add outlets. See “Selector Control Valve Kit” on page 38 for a complete description of the kits.

Torque Requirements

See “Torque Values Chart” on page 58 to determine correct torque values when tightening hardware. See “Additional Torque Values” at bottom of chart for exceptions to common torque values.

Before You Start

Read and understand the operator’s manual for your cutter. An understanding of how it works will aid in the assembly and setup of your cutter.

It is best to go through the “Assembly Checklist” below before assembling the cutter. Speed up your assembly task and make the job safer by having all needed parts and equipment readily at hand.

Assembly Checklist

Check Ref.

Have a fork lift or loader with properly sized chains and safety stands capable of lifting and supporting the equipment on hand.

Have a minimum of two people available during assembly.

Make sure all major components and loose parts are shipped with the machine.

Double check to make sure all parts, fasteners, and pins are installed in the correct location. Refer to the Parts Manual if unsure. By double checking, you will lessen the chance of using a bolt incorrectly that may be needed later.

NOTE: All assembled hardware from the factory has been installed in the correct location. Remember location of a part or fastener if removed during assembly. Keep parts separated.

Make sure working parts move freely, bolts are tight & cotter pins are spread.

Make sure all grease fittings are in place and lubricated.

Make sure all safety labels are correctly located and legible. Replace if damaged.

Make sure all red and amber reflectors are correctly located and visible when machine is in transport position.

Make sure all tires are inflated to the specified psi air pressure and all wheel bolts and axle nuts are tightened to the specified torque.

Hitch Types

The cutter is factory supplied with the standard clevis hitch. Other optional hitches are available. They include Land Pride Performance Hitch, bar-tite hitch, ball hitch, and pintle hitch. See your nearest Land Pride dealer should you want to change your hitch set-up.

Standard Clevis Hitch

Refer to Figure 1-2:

A clevis leveling rod attached to the underside of the clevis keeps the clevis parallel with tractor drawbar at all cutting heights. Cutter rotation about the tractor drawbar is limited to slots located in the clevis’ upper and lower plates and drawbar hole size.

Land Pride Performance Hitch (Optional)

Refer to Figure 1-3:

The LP Performance Hitch is a drawbar friendly, self-leveling hitch that pivots up and down and side-toside. It is held upright with customer-supplied hitch pin to allow single-person hook-up.

Bar-Tite Hitch (Optional)

Refer to Figure 1-4:

The bar-tite hitch functions similar to LP Performance Hitch except it clamps directly to the drawbar. The bar-tite hitch is sandwiched between hardened steel plates to eliminate drawbar wear. It has a bushing in the tongue to extend hitch life. Bushing and hitch swivel are greasable.

Driveline Hook-up

Refer to Figure 1-15:\

DANGER

To avoid serious injury or death:

• Do not engage power take-off while hooking-up or

unhooking the driveline, or while someone is standing near the driveline. A person’s body and/or clothing can become entangled in the driveline.

• Tractor power take-off shaft shield, driveline shields, and

gearbox shaft shields must be installed and in good working condition to avoid driveline entanglement and projectiles flying off of the driveline.

• Make certain driveline yokes are securely fastened at each

end. A loose yoke can work free allowing the driveline to rotate uncontrollably causing implement damage and bodily injury or death to anyone nearby.

WARNING

To avoid serious injury or death:

• Do not use a power take-off adapter. The adapter will

increase strain on the tractor’s power take-off shaft causing possible damage to shaft and driveline. It will also defeat the purpose of the tractor’s power take-off shield.

• Always shut tractor down using “Tractor Shutdown

Procedure” provided in this manual before dismounting tractor.

Driveline Clearance Check

Check driveline for adequate clearance under all ranges of cutter height.

NOTE: The lift cylinders should raise the cutter up while pushing the control lever forward and lower while pulling the lever back. Switch connections at the duplex outlet if lift control lever works opposite.

1. With driveline attached to the tractor, slowly raise and lower cutter to its upper and lower limits while observing clearances between hitch and driveline.

2. Adjust tractor drawbar height and length if driveline interferes. See “Drawbar Set-up” on page 13 for correct placement of tractor drawbar.

3. Cycle hydraulic lift system several times to purge hydraulic lift system of trapped air. See “Purge

Hydraulic System” on this page.

Purge Hydraulic System

Refer to Figure 1-22:

DANGER

To avoid serious injury or death: Never remove or install a folding wing cylinder with cylinder

rod r etracted and wing folded up. The wing is unstable without its folding cylinder and can suddenly fall. Also, air trapped in a new or repaired cylinder will drop the wing suddenly when lowering the wing. Either situation can render the cutter inoperable and cause serious bodily injury or death.

WARNING

To avoid serious injury or death: Be sure center and wing decks are lowered to the ground and

all hydraulic pressure is relieved before disconnecting any hydraulic lines or fittings to purge the hydraulic system.

Be sure tractor reservoir is filled properly before operating hydraulic cylinders. If tractor reservoir is low on hydraulic fluid, there is a chance of drawing air into the system causing jerky or uneven cylinder movements. The wing deck lift cylinder may be purged as follows:

1. With wings lowered to the ground, shut tractor off and move hydraulic control lever for the wings back and forth to relieve all hydraulic pressure.

2. Loosen hydraulic hoses (#3) slightly at each wing cylinder elbow (#2) to allow air and fluid to escape.

3. Restart tractor. Slowly activate tractor control lever to retract wing cylinders and to purge trapped air.

4. Once air is purged from the hydraulic system for the wing cylinders, tighten hydraulic hose fittings. at elbows (#2).

Safety Information

DANGER

To avoid serious injury or death:

• Do not walk, stand, or allow anyone else in the area wher e

a raised wing will fall unless the wing is securely locked in the raised position with its transport lock.

• Rotary Cutters have the ability to discharge objects at high

speeds; therefor e, the use of front and r ear safety guar ds are required with this cutter. Specifically, double row chain guards should be used when cutting along r oadways and in areas where people may be present. Stop blade rotation if bystanders are in or around the area.

• Tractor power take-off shaft shield, driveline shields, and

gearbox shaft shields must be installed and in good working condition to avoid driveline entanglement and projectiles flying off of the driveline.

•

Always disconnect driveline from the tractor before servicing the drivetrain and components powered by the drivetrain. A person can become entangled in the drivetrain if the tractor is started and the power take-off is engaged.

• Always secure equipment with solid, non-concr ete supports

before working under it. Never go under equipment supported by concrete blocks or hydraulics. Concrete can break, hydraulic lines can burst, and/or hydraulic controls can be actuated even when power to hydraulics is off.

• Do not operate a broken or bent driveline. Such a driveline

will break apart while r otating at high speeds and can cause serious injury or death. Always remove the implement from use until the damaged driveline can be repair ed or replaced.

• Do not raise one or both wings up with power take-off

engaged or drivelines rotating. Objects can be thrown by rotating blades. Always keep people away fr om a cutter that is operating.

• Do not use cutter as a fan. Cutting blades are not properly

designed or guarded for this use.

• The cutter must be operated with both wings attached.

Removing one wing will increase risk of r ollover. Removing one or both wings will expose blades. Blades rotating at high speed will cut body extremities and throw objects.

• Do not engage power take-off while hooking-up or

unhooking the driveline, or while someone is standing near the driveline. A person’s body and/or clothing can become entangled in the driveline.

• Never place hands or feet under the deck or attempt to make

adjustments to the cutter with power take-off engaged. Cutter blades rotating at high speeds cannot be seen and ar e located close to the deck sides. Body extremities will be cut off instantly.

• This cutter is equipped with free-swinging cutting blades to

reduce shock loads. However, it is best to avoid striking solid objects for your safety and to protect the cutter from damage.

• Keep everyone away from the cutter when folding or

unfolding the wings or when raising or lowering the cutter. The cutter can pinch or crush a person when performing these operations.

WARNING

To avoid serious injury or death:

• Allow only persons to operate this implement who have

fully read and comprehended this manual, who have been properly trained in the safe operation of this implement, and who are age 16 or older. Serious injury or death can result from the inability to read, understand, and follow instructions provided in this manual.

• Do not operate and/or travel across inclines wher e tractor

and/or implement can roll over. Consult your tractor’s manual for acceptable inclines the tractor is capable of traveling across.

RC3620 & RCM3620 Rotary Cuters 330-841M 9/25/18

Section 3: Operating Instructions

Table of Contents

Perform scheduled maintenance. Check for loose

•

hardware, missing parts, broken parts, structural cracks, and excessive wear. Make repairs befor e putting implement back into service. Serious breakdowns can result in injury or death.

• Never carry riders on the implement or tractor. Riders can

obstruct the operator’s view, interfere with control of the equipment, be pinched by moving components, become entangled in rotating components, be struck by objects, be thrown or fall from the equipment, etc.

• Always shut tractor down using “Tractor Shutdown

Procedure” provided in this manual before dismounting tractor.

• Do not raise the wing off the ground when mowing across

an incline. The weight of the wing will increase the risk of a rollover.

• Operate only power machines equipped with a certified

Roll-Over Protective Structure (ROPS) and seat belt. Keep folding ROPS in the “locked up” position when appropriate. If ROPS is in the locked up position, fasten seat belt snugly and securely to help protect against serious injury or death from falling and machine overturn.

• Clear area to be cut of debris and other unforeseen

removable objects before cutting. Mark non-removable hazards such as tr ee stumps, post stubs, pr otruding objects, rocks, drop-offs, holes, etc. with a visible flag.

• Watch while making tight turns to ensure that the rear

tractor tires and lower 3-point arms do not make contact with cutter hitch, driveline or deck. Keep lower 3-point arms raised at all times when hitched to a pull-type cutter.

• W ait for blades to come to a complete stop befor e accessing

blade bolts through blade bolt access hole.

• Do not use implement to lift objects; to pull objects such as

fence posts, stumps, etc; or to push objects. The unit is not designed or guarded for these uses.

• Do not use implement to tow other equipment unless it is

designed with a tow hitch. Doing so can result in loss of control and damage the equipment.

• Do not operate a cutter with a hitch or hitch pin that is

excessively worn, bent, broken, or has structural cracks. The hitch and/or hitch pin can break apart separating cutter from tractor.

• Do not use a power take-off adapter. The adapter will

increase strain on the tractor’s power take-off shaft causing possible damage to shaft and driveline. It will also defeat the purpose of the tractor’s power take-off shield.

•

Avoid catching hydraulic hoses on brush, posts, tree limbs,

and other protrusions that could damage and/or br eak them.

• Buildup of debris around moving components and

gearboxes is a fire hazard. Keep rotating parts and gearboxes free from debris to avoid serious injury and property damage.

• Improper oil level can cause bearing failure and be a fire

hazard. Maintain proper gearbox oil level to avoid serious injury and property damage.

• Do not exceed rated cutting capacity of your cutter. See

specifications & capacities for specified cutting capacity. Exceeding rated cutting capacity can damage drive components, cutter blades, and deck components.

CAUTION

IMPORTANT: Maintain correct power take-off speed. Loss of power take-off speed will allow blades to swing back and result in ragged, uneven cutting.

IMPORTANT: If wing driveline profile is bent or twisted, disconnect that driveline from the wing gearbox before folding the wing up. This will protect both the wing and divider gearbox. Repair driveline before putting cutter back into service.

transporting from one work site to another and before traveling on public roadways. The wings can fall if not secured with transport locks.

• Select a safe ground speed when transporting. Never travel

at a speed which does not allow adequate control of steering and stopping, and never exceed 20 mph (32.2 km/h) with attached equipment. Rough terrain requir es a slower speed.

• When traveling on public roads, use LED lights, slow

moving vehicle sign, clean reflectors, and other adequate devices to warn operators in other vehicles of your presence. If implement blocks visibility of slow moving vehicle sign, relocate sign so it is visible fr om the back at all times. Always comply with all federal, state, and local laws.

• Watch while making tight turns to ensure that the rear

tractor tires and lower 3-point arms do not make contact with cutter hitch, driveline or deck. Keep lower 3-point arms raised at all times when hitched to a pull-type cutter.

1. Select a safe ground speed when transporting from one area to another. Maximum transport speed for the Rotary Cutter is 20 mph. DO NOT EXCEED.

2. Be sure to reduce tractor ground speed when turning and leave enough clearance so the cutter does not contact obstacles such as buildings, trees or fences.

Field Set-up

WARNING

To avoid serious injury or death:

• The following operational procedur es should be carried out

by the tractor operator. Other persons should not be in the area. All cutter operations including field set-up should be stopped when other persons are in the vicinity.

• Clear area to be cut of debris and other unforeseen

removable objects before cutting. Mark non-removable hazards such as tr ee stumps, post stubs, pr otruding objects, rocks, drop-offs, holes, etc. with a visible flag.

IMPORTANT: Cutting should not be done in wet conditions. Wet material will build up on the deck underside creating need for additional horsepower, high wear, and poor discharge.

Field Inspection

Thoroughly inspect area to be cut for debris and unforeseen objects. Remove all potential hazards and mark any that cannot be removed.

33869

Wing Deck Blade Positioning

Unfold Wings and Set Deck Cutting Height

Refer to Figure 3-5:

IMPORTANT: Cutting blades may become locked together (overlapped) when the wings are raised for transport. Operating cutter in this condition will result in severe deck vibration. Inspect wings for locked blades prior to power-on operation.

Blade Carrier

Cutting Blades

Figure 3-5

Refer to Figure 3-4 on page 33:

4. Remove hairpin cotter (#1) and transport lock bar (#3) from cylinder pin (#4) on both wing sections.

Refer to Figure 3-3 on page 33:

5. Rotate end of transport lock bar (#3) up to storage lug (#2). Secure with hairpin cotters (#1).

6. Start tractor and lower both wings down.

7. Adjust cutter to field cutting height. See “Adjust Deck

Cutting Height” on page 29.

Set Wing Folding Lever In Float Position

IMPORTANT: The wing folding levers should be in

float position to avoid damage to the wing hydraulic cylinders and axles while cutting on uneven terrain.

Use the float position of your tractor’s hydraulic system to provide automatic floating of the wings for varying terrain conditions. This will ensure that the wing gauge wheels are in continuous contact with the ground at all times.

Rephasing Lift Cylinders

The rephasing lift cylinders will not function properly if they are out of phase. This will be noticeable when one deck is higher or lower than another deck. Retracting one lift cylinder, more than the other, can cause this situation.

Some tractors with pressure detents will not allow the hydraulic systems to rephase automatically. To manually rephase lift cylinders, raise cutter completely up and hold the tractor hydraulic lever on a few more seconds to give the cylinders time to rephase. Do this each time you raise the cutter and when the decks are uneven.

Momentarily reversing the hydraulic lever immediately after rephasing the lift cylinders allows the cylinders to retract about 1/2" and will help maintain a level cutter during transport.

Select Gear Range

Optimum ground speed depends on density of material being cut, horsepower rating of tractor, and (in some cases) terrain. Always operate tractor at the cutter’s full-rated power take-off speed in a gear range that allows the cutter to make a smooth cut without lugging the tractor down, usually between 2 to 5 mph. Loss of power take-off speed will allow the blades to hinge back and result in ragged, uneven cutting.

1. Inspect blade carriers for locked blades prior to lowering the wings. Separate locked blades.

2. Start tractor and raise both wings up to release any tension on the transport lock bars.

3. Without lowering the cutter, shut tractor down before dismounting. Refer to “Tractor Shutdown

Procedure” on page 17.

Table of Contents

Engage Blades

IMPORTANT: Cutter blades can lock-up against

each other during start-up and shut-down, especially if tractor’s power take-off engagement is “INSTANT ON” and/or “INSTANT OFF”. Follow Blade Engagement and Blade Disengagement instructions to help eliminate blade lock up.

1. Select a gear range that will allow the cutter to make a

smooth cut without lugging the tractor down. See “Select Gear Range” above for detailed instructions.

2. With wings lowered, increase throttle to a speed just

enough to get the cutter started without stalling tractor while slowly engaging power take-off. Use tractor’s power take-off soft start option if available.

3. Visually ensure that all power shafts are rotating and

that the cutter is not vibrating excessively after ramping up to power take-off speed for at least 3 seconds. If excessive vibration continues after 3 seconds at full power take-off speed, disengage power take-off immediately, shut down tractor and remove switch key. Wait for blades to come to a complete stop before dismounting tractor.

4. Investigate cause if cutter was shut down due to

excessive vibration. See “Blade Operation Inspection” on page 32 for detailed instructions.

5. If cutter was not shut down, commence forward

cutting operation at full power take-off operating speed. Make a new gear selection if tractor is lugging down or if cutter is making a rough cut.

6. Periodically, shut tractor down properly and dismount

to do an inspection. Refer to “Tractor Shutdown Procedure” on page 17 for proper shut down procedure.

7. Dismount tractor and check for objects wrapped

around blade spindles. Block deck up before removing objects.

8. Frequently inspect cutter for loose bolts and nuts.

Tighten all loose hardware as indicated in the

“Torque Values Chart” on page 58.

Disengage Blades

1. Slowly decrease throttle speed until engine idle speed is reached.

2. Disengage power take-off.

3. Place tractor in park or set park brake, shut tractor engine off, remove switch key, and wait for blades to stop before dismounting from tractor.

General Operating Instructions

Now that you have familiarized yourself with the Operator’s Manual, completed the Operator’s Checklist, properly attached your cutter to your tractor, made the right leveling adjustments, and preset your cutting height, you’re almost ready to begin using your Land Pride 20' Smooth Top Rotary Cutter.

It’s now time to do a running operational safety check. If at any time during this safety check you detect a malfunction in either the cutter or tractor, shut the tractor off immediately, remove the key, and make necessary repairs or adjustments before continuing.

Make sure the tractor’s park brake is engaged, tractor’s power take-off is disengaged, and the cutter is resting on the ground with both wings down. Start tractor and back throttle off until the engine is at a low idle. With tractor’s rear hydraulic lift control lever, raise the cutter to transport position making sure that the power take-off shaft is not in a bind and does not come in contact with the cutter frame. Lower unit to cutting position and with the tractor still at a low idle, engage power take-off shaft. If everything is running smoothly at this point, increase engine rpm until the tractors engine reaches full power take-off operating speed which will be either 540 or 1000 rpm. Slowly raise the cutter to transport height to make sure the driveline does not bind or chatter. Then return the engine to low idle, disengage power take-off, and position the adjustable cylinder stops on the cutter’s hydraulic lift cylinder so the cutter can be consistently returned to the same cutting and transport height. Watch while making a tight turn to ensure that the rear tractor tires do not contact the deck or hitch. Also, be sure tractor 3-point arms are raised and will not contact main driveline.

You should now be ready to move to the cutting site. Never assume an area is clear. Cut only in areas you are familiar with, have inspected, and know to be free of debris and unseen objects. Cut extremely tall grass twice to detect potential hazards. In the event you do strike an object, stop the tractor and cutter immediately to inspect cutter and make any necessary repairs before resuming operation. It pays to inspect a new area and to develop a plan before you cut.

To produce a clean cut, normal mowing speed will be between 2-5 mph at full tractor power take-off speed. Therefore, make a tractor gear and range selection that will maintain this combination. Generally the quality of cut will be better at lower ground speeds and cutting denser ground cover may create the need to slow down. You will want to avoid very low cutting heights especially on extremely uneven terrain. Always cut downward on slopes and avoid crossing the face of steep slopes. Avoid sharp drops and cross diagonally through dips to prevent hanging up the tractor and cutter. Slow down in turns and avoid sharp turns if at all possible. Remember to look back often.

Now that you’re prepared and well briefed you may begin cutting. Begin cutting by doing the following:

• Reduce tractor’s engine rpm.

• Make sure cutter wings are on the ground and in

cutting position.

• Engage power take-off, raise engine rpm to the

appropriate power take-off speed, and begin mowing.

Operators of models with a conventional main driveline must plan ahead and choose a cutting pattern that allows for wider turns. Try increasing or decreasing ground speed to determine the effect on quality of cut. With a little practice you will be pleased with what you and your Land Pride Smooth Top Cutter can do.

When you are done mowing, need to take a break, or just need to make a few adjustments to the cutter, remember to always do the following:

• Reduce tractor’s engine rpm, disengage power take-

off, and stop on level ground.

• Set the park brake, turn off engine, and remove switch

key.

• Stay on the tractor until cutter blades have come to a

complete stop.

Safety Guards

DANGER

To avoid serious injury or death: Rotary Cutters have the ability to discharge objects at high

speeds; therefore, the use of front & rear safety guards is mandatory with this cutter. Double row chain guards should be used when cutting along roadways and in areas where people may be present. Stop blade r otation if bystanders are in or around the area.

WARNING

To avoid serious injury or death: Keep all safety guards in place. Rotary Cutters have the

ability to discharge objects at high speeds. Use extreme caution when cutting in areas wher e people may be pr esent. It is best to operate the cutter when no one is nearby. Stop blade rotation if someone is in or around the area.

Land Pride offers three types of safety guards to best suit your application: rubber skirt guards, single row chain guards, and double row chain guards.

• Rubber skirt guards are designed for light duty

applications.

• Single row chain guards are constructed with a single

row of hanging chain links. They can withstand harsher applications than rubber skirts.

• Double row chain guards are constructed with two

staggered rows of hanging chain links. The second row provides an additional barrier for stopping thrown objects.

Section 5: Maintenance & Lubrication

General Maintenance Information

Proper servicing and adjustments are key to the long life of any implement. With careful inspection and routine maintenance, you can avoid costly downtime and repair.

Check all bolts and pins after using the cutter for several hours and on a regular basis thereafter to ensure they are tight and secured. Replace worn, damaged or illegible safety labels by obtaining new labels from your Land Pride dealer.

DANGER

To avoid serious injury or death: Always secure equipment with solid, non-concrete supports before working under it. Never go under equipment supported by concrete blocks or hydraulics. Concrete can break, hydraulic lines can burst, and/or hydraulic controls can be actuated even when power to hydraulics is off.

WARNING

To avoid serious injury or death:

• Perform scheduled maintenance. Check for loose

hardware, missing parts, broken parts, structural cracks, and excessive wear. Make repairs befor e putting implement back into service. Serious breakdowns can result in injury or death.

• Always shut tractor down using “Tractor Shutdown

Procedure” provided in this manual before dismounting tractor.

• Do not alter implement or replace parts on the implement

with other brands. Other brands may not fit properly or meet OEM (Original Equipment Manufacturer) specifications. They can weaken the integrity and impair the safety, function, performance, and life of the implement. Replace parts only with genuine OEM parts.

• Buildup of debris around moving components and

gearboxes is a fire hazard. Keep rotating parts and gearboxes free from debris to avoid serious injury and property damage.

• Improper oil level can cause bearing failure and be a fire

hazard. Maintain proper gearbox oil level to avoid serious injury and property damage.

Hydraulic System

One of the most important things you can do to prevent hydraulic system problems is ensure that your tractor's reservoir remains free of dirt and contamination.

Use a clean cloth to wipe hose ends clean before attaching them to your tractor. Replace tractor hydraulic filter element at the prescribed intervals. These simple maintenances will go a long way to prevent occurrence of control valve and hydraulic cylinder problems.

Tires

WARNING

To avoid serious injury or death:

• Tire changing can be dangerous and should be performed

by trained personnel using correct tools and equipment. When removing and installing wheels, use wheel handling equipment adequate for the weight involved.

• Always release all air pressure in air-filled airplane tires

before removing hardware bolting the split rims together. Not doing so can cause the split rims to blow apart instantly and could result in serious injury or death.

• When inflating tires, use a clip-on chuck and extension hose

long enough to allow you to stand to one side and NOT in front of or over the tire assembly. Use a safety cage if available. Do not over inflate tires.

• Do not weld on or heat a rim. High heat can weaken and/or

warp the rim and damage the tire. Air pressure inside the tire can increase enough to cause an explosion.

Cutter Blades

DANGER

To avoid serious injury or death:

• Always disconnect driveline from the tractor before

servicing the drivetrain and components powered by the drivetrain. A person can become entangled in the drivetrain if the tractor is started and the power take-off is engaged.

• Always secure equipment with solid, non-concr ete supports

WARNING

To avoid serious injury or death:

• Do not operate cutter with blades that are out-of-balance,

bent, excessively worn, excessively nicked, or with blade bolts that are excessively worn. Such blades can br eak loose at high speeds.

• W ait for blades to come to a complete stop befor e accessing

blade bolts through blade bolt access hole.

• W ear eye pr otection and gloves while inspecting, removing,

sharpening, and replacing a blade.

• Do not attempt to straighten a bent blade or weld on a

blade. Do not attempt to modify a blade such as hard surfacing, heat treating, cold treating, or by any other method. Always replace blades with new Land Pride blades to assure safety.

IMPORTANT: Cutting blades must be replaced in mating pairs. Not replacing both blades will result in an out-of-balance condition that will contribute to premature bearing breakdown on the spindle hub and create structural cracks in the cutter housing.

Always inspect cutting blades before each use. Make certain they are properly installed and in good working condition. Replace any blade that is damaged, worn, bent, or excessively nicked. Never try to straighten a bent blade! Small nicks can be ground out when sharpening.

Remove cutting blades and sharpen or replace as follows:

1. Park on a level, solid surface. Place tractor in park or set park brake. Unfolded wing decks until they are resting on the ground. Fully extend deck lift cylinders to lift center and wing decks up.

2. With wings unfolded and deck lift cylinders fully extended, shut tractor down. Refer to “Tractor Shutdown Procedure” on page 17.

3. Place solid support blocks under the decks.

4. Start tractor and retract deck lift cylinder until the center and wing decks are resting securely on the support blocks.

5. Shut tractor down before dismounting. Refer to “Tractor Shutdown Procedure” on page 17.

6. Disconnect main driveline from the tractor’s power take-off shaft.

Refer to Figure 5-4:

7. Remove rubber plug (#5). Rotate blade carrier (#4) until blade bolt (#1) aligns with access hole (A).

8. Unscrew locknut (#3) to remove cutter blade (#6). Blade bolt (#1) is keyed and will not turn freely.

9. Both blades should be sharpened at the same angle as the original cutting edge and must be replaced or re-ground at the same time to maintain proper balance in the cutting unit. The following precautions should be taken when sharpening blades:

a. Do not remove more material than necessary.

b. Do not heat and pound out a cutting edge.

c. Do not grind blades to a razor edge. Leave a blunt

cutting edge approximately 1/16" thick.

d. Always grind cutting edge so end of blade remains

square to cutting edge and not rounded.

e. Do not sharpen back side of blade.

f. Both blades should weigh the same with not more

than 1 1/2 oz. difference. Unbalanced blades will cause excessive vibration which can damage gearbox bearings and create structural cracks.

Refer to Figure 5-5:

10. Carefully check cutting edges of blades in relation to blade carrier rotation to ensure correct blade placement. Cutter blades must be installed with cutting edge leading in rotation.

Drivelines With Slip Clutches

WARNING

To avoid serious injury or death:

• Always shut tractor down using “Tractor Shutdown

Procedure” provided in this manual before dismounting tractor.

• A slip clutch that has been in use or has slipped for as little

as only two or three seconds during run-in may be too hot to touch. Allow a hot clutch to cool before working on it.

IMPORTANT: Prior to initial operation and after 10 days of inactivity, slip friction disks to remove oxidation and moisture. Moisture allows disks to slip easily. Oxidation can prevent disk from slipping causing driveline damage. This damage is NOT covered under the warranty.

Cutter drive components are protected from shock loads by a friction slip clutch. The clutch must be capable of slippage during operation to protect the gearbox, driveline, and other drive train parts.

Friction clutches should be “run-in” prior to initial operation and after long periods of inactivity to remove any oxidation that may have accumulated on the friction surfaces. Repeat “run-in” instructions at the beginning of each season and when moisture and/or condensation seizes the inner friction plates.

Refer to Figure 5-6 to determine which friction clutch your cutter has. Follow “run-In” instructions on the following pages for your specific clutch type.

Clutch Run-In

Refer to Figure 5-7:

1. Using a pencil or other marker, scribe a line across the exposed edges of the clutch plates and friction disks.

2. Carefully loosen each of the 8 spring retainer nuts by exactly 2 revolutions. It will be necessary to hold hex end of retainer bolt in order to count the exact number of revolutions.

3. Make sure the area is clear of all bystanders and machine is safe to operate.

4. Start tractor and engage power take-off drive for 2-3 seconds to permit slippage of the clutch surfaces. Disengage power take-off, then re-engage a second time for 2-3 seconds. Disengage power take-off, shut off tractor, and remove key. Wait for all components to stop before dismounting from tractor.

5. Inspect clutch and ensure that the scribed markings made on the clutch plates have changed position. Slippage has not occurred if any two marks on the friction disk and plate are still aligned. A clutch that has not slipped must be disassembled to separate the friction disk plates. See “Clutch Disassembly, Inspection & Assembly” below.

6. Tighten each of the 8 spring retainer nuts on the clutch housing exactly 2 revolutions to restore clutch to original setting pressure.

7. Allow clutch to cool to ambient temperature before operating again. Clutch is now ready for use.

8. The clutch should be checked during the first hour of cutting and periodically each week. An additional set of scribe marks can be added to check for slippage. See Figure 5-9 to adjust spring length.

Type B Clutches

Clutch Run-In

Refer to Figure 5-10:

1. Using a pencil or other marker, scribe a line across the exposed edges of the clutch plates and friction disks.

2. Carefully loosen each of the 6 nuts by exactly 1 revolution. It will be necessary to hold hex end of retainer bolt in order to count exact number of revolutions.

3. Make sure the area is clear of all bystanders and machine is safe to operate.

4. Start tractor and engage power take-off drive at idle for 2-3 seconds to permit slippage of friction plates. Disengage power take-off, shut off tractor and remove key. Wait for all components to come to a complete stop before dismounting from tractor.

5. Inspect clutch to ensure that the scribed markings made on the clutch plates and friction disc have changed positions. If any two marks are still aligned, then the clutch did not slip as it should. Skip to step 8 if all clutch plates slipped.

6. If the friction clutch did not slip, loosen the nuts one more revolution. Make sure the nuts have full thread engagement on the bolt and then repeat steps 4 - 5.

7. A clutch that does not slip must be disassembled to separate the friction disk plates. See “Clutch Disassembly, Inspection & Assembly” below.

8. Tighten each of the nuts on the clutch back to their original location to restore clutch pressure.

9. Allow clutch to cool to ambient temperature before operating again. Clutch is now ready for use.

10. The clutch should be checked during the first hour of cutting and periodically each week. An additional set of scribe marks can be added to check for slippage.

Figure 5-11

Clutch Disassembly, Inspection & Assembly

Refer to Figure 5-11:

The clutch must be disassembled into its separate friction disks if clutch run-in procedure indicated that one or more friction disks did not slip. See disassembly instructions.

Disassembly

IMPORTANT: Do not remove nuts (#8) from

bolts (#7) until after Belleville spring (#6) is relaxed and not pressing against any of the six nuts (#8).

1. Unscrew nuts (#8) equal amounts until all belleville spring tension is removed. Do not remove nuts until tension against all nuts has been removed.

2. Remove nuts (#8) and bolts (#7).

3. Separate all friction disks (#2) from plates (#4 & #5), hub (#3) and yoke flange (#1).

Inspection

Assembly

1. Reassemble each friction disk (#2) next to the metal plate it was separated from.

2. Install bolts (#7) through end plates and intermediate plates as shown and secure with nuts (#8).

IMPORTANT: Measurement “A” is an approximate gap. Variations in spring force and friction materials may cause some differences in torque values. Tightening nuts (#8) 1/6 of a turn will compress belleville spring (#6) 0.25 mm (.010”).

3. Tighten belleville spring (#6) until spring is tight against drive plate (#4) & then back nuts (#8) up 2 2/3 revolutions, “A” should = 4.0 mm (0.157”).

Section 5: Maintenance & Lubrication

Long-Term Storage

Clean, inspect, service, and make necessary repairs to the cutter when storing it for long periods and when storing it at the end of a working season. This will help ensure the cutter is ready for field use the next time you hook-up to it.

DANGER

To avoid serious injury or death:

• Always disconnect driveline from the tractor before

servicing the drivetrain and components powered by the drivetrain. A person can become entangled in the drivetrain if the tractor is started and the power take-off is engaged.

• Always secure equipment with solid, non-concr ete supports

1. Clean off any dirt and grease that may have accumulated on the cutter and moving parts. Scrape off compacted dirt from the bottom of deck and then wash surface thoroughly with a garden hose. A coating of oil may also be applied to the lower deck area to minimize oxidation.

2. Check blades and blade bolts for wear and replace if necessary. See “Cutter Blades” on page 41.

3. Inspect for loose, damaged, or worn parts and adjust or replace as needed.

4. Repaint parts where paint is worn or scratched to prevent rust. Ask your Land Pride dealer for aerosol touch-up paint. Paint is also available in touch-up bottles with brush, quarts, and gallon sizes by adding TU, QT, or GL to the end of the aerosol part number.

Ordering Replacement Parts

Land Pride offers equipment in factory standard Beige with black highlights. This implement may also be purchased in Orange, Green, or Red.

When ordering an optional color, the suffix number corresponding to the color must be added at the end of the part number. Parts ordered without the suffix number will be supplied in factory standard colors.

81 . . . . . . . Green

82 . . . . . . . Orange

For example, if you are ordering a replacement part with part number 555-555C and the existing part is orange, then add the suffix 82 to the end of the number to make the part number read 555-555C82.

5. Replace all damaged or missing guarding and decals.

6. Lubricate as noted in “Lubrication Points” starting on page 47.

7. Store cutter on a level surface in a clean, dry place. Inside storage will reduce maintenance and make for a longer cutter life.

8. Follow all unhooking instructions on page 26 when disconnecting tractor from cutter.
