parts when removing or installing the battery.
Do not allow metal tools to short between the battery terminals
and metal tractor parts.
WARNING: Incorrect battery cable routing could cause damage
to the tractor and battery cables. This can cause sparks which can
cause a battery gas explosion which will result in personal injury.
Always disconnect the negative (black) battery cable before
disconnecting the positive (red) cable.
Always connect the positive (red) battery cable before connecting
the negative (black) cable.
Common circuit failures are usually caused by shorting, corroded or
dirty terminals; loose connections, defective wire insulation or broken
wires. Switches, solenoids and ignition components may also fail, causing
a shorted or open circuit.
The electrical system is protected by fuses located on the right fuel tank
instrument panel. Fig. 9-3 The fuses are as follows:
Main - 20 amp, blade-type
Clutch/Aux - 10 amp, blade-type
Before attempting any failure diagnosis of the electrical system, use a
test light or voltmeter to check the battery voltage. If the battery voltage is
satisfactory, check the cleanliness and tightness of the terminals and ground
connections. A general understanding of electrical servicing and use of
basic test equipment is necessary for troubleshooting and repair.
Major overhaul or repair of the starting motor or charging system
should be performed by trained technicians only.
Access to integrated pump/motor units
The integrated pump/motor units are accessed by lifting the seat
platform. The seat platform is hinged at the front. To raise it, remove the
two cap screws and tilt seat platform up and forward. (Fig. 9-4)
If the seat is equipped with the optional arm rest kit, make certain
to place the control arms in the park brake position and pivot the arm
rests upward before placing the seat platform in the full forward
position to prevent damage to the arm rests.
Hydraulic system
The Hustler FasTrak 44/52 is equipped with two Hydro-Gear C-IZT
integrated pump/motor transmissions. Fig. 9-5
Units built prior to serial number 03037002 are sealed for life and do
not require scheduled service.
Units starting with serial number 03037002 and later have a
replaceable filter which will require replacement every 200 hours or 2 years
whichever comes first. The required service involves draining the oil and
installing a new filter kit (Hustler p/n 789511). Fill with new 20W50
engine oil.
WARNING: Never work under the machine or attachment unless
it is safely supported with jack stands. Make certain machine is
secure when it is raised and placed on the jack stands. The jack
stands should not allow the machine to move when the engine is
running and the drive wheels are rotating. Use only certified
jack stands. Use only appropriate jack stands, with a minimum
weight rating of 2000 pounds to block the unit up. Use in pairs
only. Follow the instructions supplied with the vehicle stands.
To replace the filter use the following procedure:
1. Raise and block the tractor up so the drive wheels are off the floor.
Place the jack stands under the engine guard to support the
machine. Fig. 9-6
WARNING: Make sure the transmissions are cool before
performing service procedures.
2. Remove the drain plug and filter from the integrated pump/motor
transmission and drain the oil into a drain pan. Dispose of the oil
in a proper manner. This oil will not be re-used. Fig. 9-7
3. Install a new filter kit into the transmission.
4. Remove the lower side plug and install the magnetic plug included
with the kit. Fig. 9-7
