NOTES:
1.Initial oil change is after 5 hours of operation. Thereafter, change oil after every 40 hours operation. Change more often under dusty or dirty conditions and during hot weather periods.
2.Torque initially and after first 2 hours of operation.
3.Change engine oil filter per the engine manufacturer’s recommendations. Refer to Engine Owner’s Manual for recommendations and other maintenance items.
4.Service more often under dusty or dirty conditions.
5.Pump drive belt only - Inspect every 6 months or 100 hours and replace if worn or cracking is noticed. Otherwise, replace every 200 hours or 2 years whichever comes first.
6.Check fuel line hoses, fuel valve and grommet for any cracks or leaks
7.Change the filter and oil using 20W50 motor oil.

NOTE: After completing maintenance cycle (100 hours), repeat cycle.
Introduction
Regular maintenance is the best prevention for costly downtime or expensive, premature repair. The following pages contain suggested maintenance information and schedules which the operator/mechanic should follow on a routine basis.
Remain alert for unusual noises, they could be signaling a problem. Visually inspect the machine for any abnormal wear or damage. A good time to detect potential problems is while performing scheduled maintenance service. Correcting the problem as quickly as possible is the best insurance.
Clear away heavy build-up of grease, oil and dirt, especially in the engine and under the seat platform areas; minute dust particle are abrasive to close-tolerance engine and hydraulic assemblies.
Daily inspect mower for grass clippings and wire and string tangles. The underside of the mower deck will collect a build-up of grass clippings and dirt, especially when grass is wet or has high moisture content. This build-up will harden, restricting blade and air movement and will probably show a poorer quality of cutting. Therefore it should be removed routinely.
To do this it will be necessary to raise and block the deck, using jack stands or blocks, in the full up position and scrape the build-up from underneath.
Some repairs require the assistance of a trained service mechanic and should not be attempted by unskilled personnel. Consult your Hustler service center when assistance is needed.
Torque values
WARNING: Particular attention must be given to tightening the drive wheel lug nuts and blade spindle bolts. Failure to correctly torque these items may result in the loss of a wheel or blade, which can cause serious damage or personal injury.
Torque values given below:
Ft-lbs. Nm
Wheel (lug) nuts . . . . . . . . . . . . . . . . . . . . . . .65-75 . . . . . .88.14-101.7 Blade spindle bolt top . . . . . . . . . . . . . . . . . . .118 . . . . . . . . .160.01 Blade spindle bolt bottom . . . . . . . . . . . . . . . .118 . . . . . . . . .160.01
It is recommended that these be checked after the first 2 hours of operation, initially and every 50 hours following removal for repair or replacement.
For all other torques refer to the torque callout chart located elsewhere in this manual.
For engine torque values, see engine owner’s manual.
Tires
It is important for level mowing that the tires have the same amount of air pressure. The recommended pressures are:
Drive wheels . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .8-10 psi Gauge wheels . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .8-10 psi
Solid fill tires are not recommended for Hustler turf equipment. On any machine, with solid filled tires, the warranty 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. Welding can weaken or deform a wheel.
When inflating tires stand to one side and not in front of or over the tire assembly.
Check tires for low pressure, blemishes, damaged rims or missing lug bolts and nuts.
Lubrication
1.Grease the front gauge wheel bearings per the Maintenance Schedule. Use SAE multi-purpose grease.
2.Grease the four deck lift pivots, located to the side of the operator’s footrest per the Maintenance Schedule. Use SAE multi-purpose grease.
Electrical system
The electrical system is a 12 volt, negative ground. Recommended battery size is a garden tractor BCI group U1R with 225 or better cranking AMP rating. A maintenance-free battery is recommended. Otherwise, follow battery manufacturer’s maintenance, safety, storing and charging specifications.
The battery is located under the seat platform. Fig. 9-2
WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.
WARNING: Avoid skin and clothing contact with battery acid. Always wear eye protection when checking the battery, acid can cause serious injury to skin and eyes. If contact occurs, flush area with clean water and call physician immediately. Acid will also damage clothing.
Do not drink the battery electrolyte.
Do not allow open flame near the battery when charging. Hydrogen gas forms inside the battery. This gas is both toxic and flammable and may cause an explosion if exposed to flame. Always remove the negative ground first and replace it last.
Do not overfill battery.
Electrolyte may overflow and damage paint, wiring or structure. When cleaning the battery, use soap and water. Be careful not to get soap and water into the battery. Clean the battery terminals with a solution of four parts water and one part baking soda when they become corroded.
WARNING: Shorts caused by battery terminals or metal tools touching metal tractor components can cause sparks. Sparks can cause a battery gas explosion which will result in personal injury. Prevent the battery terminals from touching any metal tractor
