Hydraulic oil heat exchanger
These mowers are equipped with a hydraulic oil heat
exchanger. The heat exchanger coils must be kept clean to
insure that the hydraulic oil is operating within the correct
temperature range.
Check and clean the heat exchanger daily and more often
in dirty, dusty conditions. Figure 4-4

Fuel System

Refer to the Safety section of this manual for fuel handling
safety information.
IMPORTANT: Refer to the engine owner's manual for addi-
tional emissions control information.
The fuel tanks are located in the mower's fenders. These
engines require number 2 diesel fuel only.
Park the mower on level ground before filling the fuel tank.
Clean the area around the fuel cap before removing the
cap. Remove the fuel cap slowly.
Fuel Shut-off Valve
®
The Hustler Z Diesel mower is equipped with a fuel shut-
off valve located to the right rear of the seat. Rotate the valve
to the middle position to allow fuel to flow from the right fuel
tank to the fuel pump. The right position prevents fuel flow to
the fuel pump. The left position allows fuel to flow from the
left fuel tank to the fuel pump. Close this valve to prevent fuel
flow to the engine when servicing the fuel system or when
transporting the unit on a trailer or truck. Figure 4-5
Priming the Fuel System
If the diesel fuel system runs dry, use the following proce-
dure when re-starting the engine:
1. Refill the fuel tanks.
2. Make sure the fuel shutoff valve is turned to the full
fuel tank.
3. Take the priming bulb and compress it until it becomes
firm. Figure 4-6
4. Try and start the engine. If it will not start after 15 sec-
onds of cranking, repeat Step 3.
If after trying several times, the engine still will not start,
contact your Hustler Dealer.
