 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

 Park on solid, level ground and

lower implement to ground or onto support blocks.

 Put tractor in park or set park

brake, turn off engine, and remove switch key to prevent unauthorized starting.

 Relieve all hydraulic pressure to

auxiliary hydraulic lines.

 Wait for all components to stop

before leaving operator’s seat.

 Use steps, grab-handles and

anti-slip surfaces when stepping on and off the tractor.

 Detach and store implement in an

area where children normally do not play. Secure implement using blocks and supports.

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.

11/6/18

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.

DANGER

To avoid serious injury or death: Do not use a power take-off adapter with a quick hitch. 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.

WARNING

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.

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

“B” are not properly maintained.

Maintain proper distance, dimension “A”, between center of drawbar hitch pin hole and end of tractor power take-off shaft.

Before You Start

Read and understand this Operator’s Manual for your cutter. An understanding of how the cutter works will aid in the assembly and setup of your cutter.

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

Torque Requirements

See “Torque Values Chart for Common Bolt Sizes” 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.

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 pneumatic tires are properly inflated and all wheel bolts and axle nuts are tightened to the specified torque.

Hitch Types

The following are the five hitch types offered. See your nearest Land Pride dealer should you want to change your hitch set-up.

Fixed Clevis Hitch (Optional)

Refer to Figure 1-2:

Cutter rotation about the tractor drawbar is limited to slot in the upper clevis plate, hole size in the lower clevis plate, and drawbar hole size. Customer to supply hitch pin and hitch pin keeper.

NOTE: The 5/8" bolt (#1) and spacer (#2) may be removed for more flexibility of hitch. If bolt and spacer are removed, an equal number of washers should be added above the drawbar and below the drawbar to remove gap between drawbar and clevis hitch. Adding washers when bolt and spacer are removed will reduce drawbar and hitch wear.

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.

Ball Hitch (Optional)

Refer to Figure 1-5:

Cutter rotation about the tractor drawbar is limited to swivel movement over the 2 5/16" tractor mounted ball.

Pintle Hitch (Optional)

Refer to Figure 1-6:

Cutter rotation about the tractor drawbar is limited to movement about the pintle connection. The pintle hitch is ideal for a drawbar hammer strap.
