Hustler Turf Lawn Mower - Manual (Page 82)

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
