Maintenance & Adjustment Safety This safety alert symbol is used to call attention to a message intended to provide a reasonable degree of PER- SONAL SAFETY for operators and other persons during the normal operation and servicing of this equipment. DANGER denotes immediate hazards which WILL result in severe personal injury or death.
▲ Except when changing or checking belt, always keep belt covers on mower for safety as well as cleanliness. ▲ Stop the engine before removing the grass catcher or unclogging the discharge chute. Never clear the discharge chute with the engine running. Turn off the engine and be sure the blades have stopped before cleaning. Use a stick to clear a plugged discharge area.

The following illustrations show the various decals that are located on the machine. A brief explanation, for those requiring one, is shown to help the operator understand the meanings of these decals. Read Owner’s Manual and Quick Reference Decal before attempting to operate this machine. Avoid skin contact with battery acid.
Page 127
If you lose steering control while operating the machine, place the steering control levers in the park brake position immediately. Inspect the machine and involve your Hustler dealer to resolve the problem before continuing to operate. If pump belt fails, steering control will be lost. Refer to owner’s manual for inspection and Part Number replacement intervals and refer to above paragraph for emergency procedures.

It is important for level mowing that the tires have the same amount of air pressure. The recommended pressure are: Solid fill tires are not recommended for Hustler turf equipment. On any machine, with solid filled tires, the war- ranty claim will be denied.
WARNING: Explosive separation of a tire and rim can cause serious injury or death. Do not attempt to mount a tire without the proper equipment and experience to perform the task. Always maintain the correct tire pressure and never over inflate. Never weld or heat a wheel and tire assembly as an explosion may occur.
Electrical system The electrical system is a 12-volt, negative ground. Recommended battery size is a garden tractor BCI group 45 with 480 or better cranking AMP rating. A maintenance-free battery is recommended. Otherwise, follow battery manu- facturer’s maintenance, safety, storing and charging specifications.The battery is located at the rear of the tractor, FIG.
Access to engine and hydraulic pumps The hydraulic pumps are accessed by lifting the seat platform. The seat platform is hinged at the front. To raise it, release seat latch and tilt seat platform up and forward.The seat platform catch (FIG. 29) will prevent the seat from going all the way over.

HYDRAULIC RESERVOIR 1. Smear a light coating of oil on filter’s o-rings. 2. Insert the filter element into the hydraulic reservoir housing. Tighten the oil filter 10 ft.- lbs. (13.56 Nm) — DO NOT OVERTIGHTEN. 3. Start tractor engine and let run at approximately 2/3 throttle for a few minutes to work any trapped air out of the system before engaging the steering control lever.
Fuel system DANGER: Observe usual fuel handling precautions: Do not smoke while refueling. Do not fill tank with engine running or while engine is hot. Clean up any diesel fuel spills. Allow engine to cool before storing machine inside a building. Keep fuel away from open flame or spark and store machine away from open flame or spark if there is fuel in the tank.

4. Try and start the engine. If it will not start after 15 seconds of cranking, repeat Step 3. 5. If after trying several times and the engine still will not start, contact your Hustler Dealer. Hustler Z Diesel tractors are equipped with a fuel shutoff valve located on the lower right of the front engine guard (FIG.
Engine oil and filter Check engine oil daily and after every 4 hours of operation. The crankcase dipstick is located at the front of the engine (FIG. 35) and oil filler tube is located on top of the engine (FIG. 36). Tractor must be sitting level when checking oil.
OIL REMOVAL FROM THE ENGINE BREATHER VALVE SYSTEM IN THE EVENT THAT OIL ENTERS THE ENGINE BREATHER VALVE SYSTEM, THE OIL MUST BE REMOVED BEFORE CRANKING THE ENGINE. 1. If oil has entered the engine breather valve system, it may be found in the intake manifold.
Page 139
The filter element must be sufficient size and construction to withstand stresses, caused by rapid cycling of the air volume demanded by the engine, without cracking or tearing under fatigue and pressure (especially diesel engines). Therefore, Hustler Turf Equipment and the engine manufacturers have carefully selected a reliable filter designed to fit the needs of the engines.

element slowly, looking for any holes or tears in the paper. Also check gaskets for cuts or tears. Do not attempt to use a damaged element which will allow abrasive particles to enter the engine. 3. Reinstall the dust cup. Make sure it seals all the way around the air cleaner body, then tighten the clamps.

Viewed from right side of unit 1. Electric deck clutch 2. Deck drive belt 3. Fixed pulley FIG. 46 WARNING: If the pump belt fails, loss of control will occur especially when operating on a slope. If you lose steering control while operating the machine, place the steering control levers in the park brake position immediately.
Do not sharpen to original pattern (below). It is easier to get a straight cutting edge following the re sharpening pattern shown above FIG. 48 Mower blade removal Use a 15/16" wrench to remove the 5/8" cap screw holding the blade to the spindle shaft from underneath. Sharpen the blades on a grinder following pattern as shown (FIG.
Introduction Your Hustler Z Diesel was adjusted before it left the factory and was checked during predelivery setup. However, after start-up and continued use, a certain amount of break-in wear will cause some adjustments to change. Remain alert for unusual noises, they could be signaling a problem. Visually inspect the machine for any abnormal wear or damage.
JAM NUT PUMP LINKAGE FIG. 52 If the tractor creeps in the neutral position the control linkage may be adjusted as follows: 1. Raise and block the tractor up so the drive wheels are off of the floor. WARNING: Never work under the machine or attachment unless it is safely supported with jack stands.
To adjust the stops for driving straight when control levers are against the stops during operation: 1. Determine which drive tire is rotating too fast when both control levers are against the stops. Then stop the tractor and loosen the lock nut on the side which is rotating too fast and turn the stop (set screw) inward to stop the control lever sooner.
Control lever adjustment The control levers can be adjusted for operator comfort. By loosening the cap screws that attaches the upper control lever to the lower lever FIG. 56, the upper control lever can be pivoted to fit the operator’s personal preference. The control levers should be adjusted so that they align with each other when in the neutral position.
Hydraulic pump belt adjustment The pump drive belt tension remains constant by means of a tension idler and spring (FIG. 58). There is no tension adjustment of this belt. NOTE: Replace the belt every 400 hours or every two (2) years whichever comes first.
Engine RPM setting The Hustler Z Diesel is designed so that the engine will run at 2950 rpm static pump load only. At this speed the hydraulic pumps are running at their maximum rated speed. Deck leveling and height adjustment The mower deck has three areas that may need to be checked and adjusted periodically.

15. Be sure that adjuster is free to move up and down. 16. Tighten the adjuster bolt until the chain just becomes tight, making sure that the deck stays tight against the 3" block. 17. Tighten the adjuster bolt jam nut to prevent the adjuster bolt from moving (FIG. 65). 18.
Page 151
23. Go to the left rear of the tractor. 24. Make sure that there is still slack in the chain. If not, loosen the two nuts on the block holding the threaded rod until there is slack in the deck lift chain (FIG. 63). 25.
