SAFETY RULES
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
Safety is a primary concern in the design and manufacture of our products. Unfortunately, our efforts to provide safe equipment can be wiped out by an operator’s single careless act.
In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, judgement, and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.
It has been said “The best safety device is an informed, careful operator.” We ask you to be that kind of operator.
TRAINING
Safety instructions are important! Read all attachment and power unit manuals; follow all safety rules and safety decal information. (Replacement manuals and safety decals are available from your dealer.) Failure to follow instructions or safety rules can result in serious injury or death.

Remove accumulated debris from this equipment, power unit, and engine to avoid fire hazard.
Make sure all safety decals are installed. Replace if damaged. (See Safety Decals section for location.)
Make sure shields and guards are properly installed and in good condition. Replace if damaged.
A minimum 20% of tractor and equipment weight must be on the tractor front wheels when attachments are in transport position. Without this weight, tractor could tip over, causing personal injury or death. The weight may be attained with a loader, front wheel weights, ballast in tires or front tractor weights. Weigh the tractor and equipment. Do not estimate.
Inspect and clear area of stones, branches, or other hard objects that might be thrown, causing injury or damage.
If you do not understand any part of this manual and need assistance, see your dealer.
Know your controls and how to stop engine and attachment quickly in an emergency.
Operators must be instructed in and be capable of the safe operation of the equipment, its attachments, and all controls. Do not allow anyone to operate this equipment without proper instructions.
Never allow children or untrained persons to operate equipment.

OPERATION
The operator is responsible for the safe operation of the mower. The operator must be properly trained. Operators should be familiar with the mower, tractor, and all safety practices before starting operation. Read the safety rules and safety decals on pages 5 to 8.
This mower is designed for lawn and grass mowing. It is not designed for rough conditions or heavy weed mowing. It is equipped with suction type blades for best results in lawn mowing.
Recommended mowing speed for most conditions is from 2 to 5 mph.
Never allow children or untrained persons to operate equipment.
Keep bystanders away from equipment.
Make sure spring-activated locking pin or collar slides freely and is seated firmly in tractor PTO spline groove.
Operate tractor PTO at 540 RPM. Do not exceed.
CAUTION
Stop power unit and implement immediately upon striking an obstruction. Dismount power unit, using proper procedure. Inspect and repair any damage before resuming operation.
Always wear relatively tight and belted clothing to avoid getting caught in moving parts. Wear sturdy, rough-soled work shoes and protective equipment for eyes, hair, hands, hearing, and head; and respirator or filter mask where appropriate.
TRACTOR STABILITY
A minimum 20% of tractor and equipment weight must be on the tractor front wheels when attachments are in transport position. Without this weight, tractor could tip over, causing personal injury or death. The weight may be attained with a loader, front wheel weights, ballast in tires or front tractor weights. Weigh the tractor and equipment. Do not estimate.

CUTTING HEIGHT ADJUSTMENT
Keep all persons away from operator control area while performing adjustments, service, or maintenance.
NOTICE
■ Avoid low cutting heights. Striking the ground with blades produces one of the most damaging shock loads a mower can encounter. Allowing blades to contact ground repeatedly will cause damage to mower and drive.
1.Level mower from side to side. Check by measuring from mower frame to the ground at each deck rail.
2.Adjust, using tractor 3-point arm leveling device.
NOTE: Best mowing results will be obtained with front of mower level with or slightly lower than the rear.
3.Control cutting height with tractor 3-point arms and front and rear caster wheel adjustment.
4.Raise rear of mower, move caster adjustment spacers under caster arms. Hex opening of blade wrench fits bolts on top of caster shaft.
5.Raise front of mower with tractor 3-point arms. Move spacers under front caster wheel arms.
NOTE: Cutting height is the distance between the blade and the ground. The blades are 7-3/4" below the top of the deck rail on the GM1060 and 8-3/4" below the top of the deck rail on the GM1072. To check cutting height, place a straight edge along top edge of deck rail as shown in Figure 4.
6.Measure from bottom of straight edge to the ground at locations A and B. Subtract 7-3/4" on GM1060 (8-3/4" on GM1072) from measurement B to determine cutting height.
Figure 4. Cutting Height Adjustment
NOTE: Remember, measurement at location A, Figure 4, should not be less than location B and should not be over 1/2" greater than location B.

■ Do not operate tractor and mower until this interference check has been performed. If you change tractors, you must perform the check for that mounting.
Perform this check with all of the spacers and springs above the caster wheel arm. This will place the caster wheels in their highest position and provide the lowest cutting height for the mower.
Raise mower with tractor hydraulics to 16" at dimension C or maximum height of tractor lift, whichever is less.
Pivot both front caster wheels forward and check that there is clearance between caster wheels and tractor tires. If there is interference, you must not use front caster wheels on the mower with this tractor.
Figure 7. Front Gauge Wheel Interference Check
FRONT ROLLER (OPTIONAL)
The caster wheels and side skids effectively reduce scalping in most cases. However, you may encounter areas where the caster wheels and/or side skids drop into depressions and allow center of mower to contact ground and scalp. An optional front roller may be installed to minimize scalping.
For Installation instructions See “Front Roller Installation (Optional)” on page 30.
Power for operating mower is supplied by tractor PTO. Operate PTO at 540 rpm. Know how to stop tractor and mower quickly in an emergency.
If mower becomes plugged causing belt to slip for over two seconds, follow these steps:
1.Maneuver equipment into a previously cut area and allow mower to clear accumulated material.
2.Continue running at least two minutes, allowing pulleys to cool. Stopping the mower in contact with a very hot pulley will bake and ruin belt.
Proper ground speed will depend upon the terrain, the height, and type and density of material to be cut.
Normally, ground speed will range from 2 to 5 mph. Tall dense material should be cut at a low speed; thin medium-height material can be cut at a faster ground speed.
OPERATING TECHNIQUE
CAUTION
Stop power unit and implement immediately upon striking an obstruction. Dismount power unit, using proper procedure. Inspect and repair any damage before resuming operation.
Always operate tractor PTO at 540 rpm to maintain proper blade speed and produce a clean cut.
Under certain conditions, tractor tires may roll some grass down and prevent it from being cut at the same height as the surrounding area. When this occurs, reduce your ground speed, but maintain PTO at 540 rpm. The lower ground speed will permit grass to partially rebound.
In general, lower cutting heights give a more even cut and leave less tire tracks. However, it is better to cut grass frequently rather than too short. Short grass deteriorates rapidly in hot weather and invites weed growth during growing seasons. Follow local recommendations for the suitable cutting height in your area.
OPERATING TIPS
Inspect and clear area of stones, branches, or other hard objects that might be thrown, causing injury or damage.
NOTICE
■ Mower vibration tends to loosen bolts during operation. All hardware should be checked regularly to maintain proper torque. It is a good practice to check mower before each operation to ensure all hardware is secure.
Extremely tall material should be cut twice. Set mower at a higher cutting height for the first pass. Then cut at desired height, 90 degrees to the first pass.
Remember, sharp blades produce cleaner cuts and require less power.

Analyze area to be cut to determine the best procedure. Consider height and type of grass and terrain type: hilly, level, or rough.
Plan your mowing pattern to travel straight forward whenever possible. Mow with uncut grass to the right. This will distribute the clippings over the cut area.
UNEVEN TERRAIN
Do not operate or transport on steep slopes.
Do not stop, start, or change directions suddenly on slopes.
Use extreme care and reduce ground speed on slopes and rough terrain.
Watch for hidden hazards on the terrain during operation.
Pass diagonally through sharp dips and avoid sharp drops to prevent hanging up tractor and mower.
Practice will improve your skills in maneuvering rough terrain.
STORAGE
Figure 8. Mower Storage Position
1.Disengage tractor PTO and raise mower with the 3-point hitch.
2.Collapse driveshaft as far as possible and store it in PTO hanger bracket to prevent ground contact.
3.Place blocks under mower side skids. Lower mower onto blocks, disconnect mower from tractor 3-point hitch, and carefully drive tractor away from mower.

OWNER SERVICE
The information in this section is written for operators who possess basic mechanical skills. If you need help, your dealer has trained service technicians available. For your protection, read and follow the safety information in this manual.
CAUTION
Always wear relatively tight and belted clothing to avoid entanglement in moving parts. Wear sturdy, rough-soled work shoes and protective equipment for eyes, hair, hands, hearing, and head; and respirator or filter mask where appropriate.
Never go underneath equipment (lowered to the ground or raised) unless it is properly blocked and secured. Never place any part of the body underneath equipment or between moveable parts even when the engine has been turned off. Hydraulic system leak down, hydraulic system failures, mechanical failures, or movement of control levers can cause equipment to drop or rotate unexpectedly and cause severe injury or death. Follow Operator's Manual instructions for working underneath and blocking requirements or have work done by a qualified dealer.
Keep all persons away from operator control area while performing adjustments, service, or maintenance.
Before working underneath, carefully read Operator’s Manual instructions, disconnect driveline, raise mower, securely block up all corners with jackstands, and check stability. Secure blocking prevents equipment from dropping due to hydraulic leak down, hydraulic system failures, or mechanical component failures.
Make sure spring-activated locking pin or collar slides freely and is seated firmly in tractor PTO spline groove.
BLOCKING METHOD
Jackstands, with a load rating of 1,000 pounds or more, are the only approved blocking device for this mower. A minimum of four jackstands, located under the mower as shown in Figure 9, must be installed before working underneath this unit. Do not position jackstands under wheels, axles, or wheel supports because these components can rotate.
Do not work underneath unless it is properly attached to tractor (see Operation section), the brakes set, key removed, and the mower blocked securely. Tighten tractor lower 3-point arm anti-sway mechanisms to prevent side to side movement.
When blocking, you must consider overall stability of the unit. Just placing jackstands under the unit will not ensure your safety. The working surface must be level and solid to support the weight on the jackstands. Ensure jackstands are stable both top and bottom, and mower is approximately level. With full mower weight lowered on jackstands, test blocking stability before working underneath mower.

Figure 10. Lubrication Points & Chart
LUBRICATION INFORMATION
Do not let excess grease collect on or around parts, particularly when operating in sandy areas.
Figure 10Figure 10 shows the lubrication points. The accompanying chart gives the frequency of lubrication in operating hours, based on normal operating conditions. Severe or unusual conditions may require more
frequent lubrication. Some reference numbers have more than one location; be sure you lubricate all locations.
Use a lithium grease of #2 consistency with a MOLY (molybdenum disulfide) additive for all locations. Be sure to clean fittings thoroughly before attaching grease gun. When applied according to the lubrication chart, one good pump of most guns is sufficient.
14 Owner Service |
5WPMAN0242 (Rev. 7/21/2008) |
|
Use SAE 80W or 90W gear lube in the gearbox. Fill to plug on side of gearbox.
Check gearbox daily for evidence of leakage at both seals and the gasket between the housing and cover. If leakage is noted, repair immediately. There may be a small amount of lube emitted from the vent plug; this is not considered leakage.
Overfilling the gearbox will cause the excess gear lube to blow out vent plug and ruin the belt.
Driveshaft Lubrication
Lubricate the driveshaft slip joint every 8 operating hours. Failure to maintain proper lubrication could result in damage to U-joints, gearbox, and driveshaft.
1.Lower mower to ground.
2.Apply grease at the three locations as shown in Figure 10.
3.Raise and lower mower several times to distribute grease.
BELT
Belt Replacement
One of the major causes of belt failure is improper installation. Before installing a new belt, check the following:
1.Check pulley shafts and bearings for wear.
2.Check pulley grooves for cleanliness.
3.Make sure spindles turn freely and without wobble.
If grooves require cleaning, moisten a cloth with a nonflammable, non-toxic degreasing agent or commercial detergent and water.
Avoid excessive force during installation. Do not use tools to pry belt into pulley groove. Do not roll belt over pulleys to install. This can cause hidden damage and premature belt failure.
Belt Installation
Refer to Figure 11.
NOTICE
■ Use care when installing or removing belt from spring-loaded idler at step 5. Springs store energy when extended and, if released suddenly, can cause personal injury.
1.Disconnect idler spring from deck lug.
2.Slide belt under drive pulley A and over idler arm. Position belt around drive pulley A.
3.Loosen bolt holding belt guide G and swing it away from pulley B. Route belt around pulley B, idler C and pulley D as shown.
4.Make sure belt is on drive pulley A, route around idler F, and connect idler spring to lug on deck.
5.Grasp belt between spindle pulley E, spring loaded idler F and spindle pulley D. Pull spring loaded idler with belt to obtain enough belt length to route it over pulley E. Make sure spring-loaded idler pivots freely with belt installed.
6.Adjust belt guide G to provide 1/16" to 1/8" clearance from belt. Tighten bolt to 85 lbs-ft.
