and repair the source of ingested dirt.

Super Z liquid cooled/Super Z Diesel
The Super Z liquid cool tractor and Super Z Diesel are equipped with a
safety filter. The filter element slides over the safety filter.
NOTE: The safety filter does not require servicing unless it becomes
contaminated with dirt or moisture.
Air restriction indicator
Some Hustler units have an air restriction indicator installed in the air
cleaner. Fig. 4-6
Replace the element whenever the restriction indicator shows reaches the
change filter red line. Check the indicator daily and replace element as
needed or annually whichever occurs first.
Reset the indicator by pushing in on the yellow button after each element
change. Fig, 4-6
Cooling system
Super Z liquid cooled
DANGER: Never remove radiator cap or overflow reservoir
cap when engine is hot. Pressurized hot steam and water may
be released, causing serious burns or possible blindness.
Engine cooling is accomplished with circulated water and Ethylene
Glycol mixture. The radiator is equipped with a pressure cap and overflow
reservoir. Follow the information found in the engine owner’s manual for
the recommended coolant solution.
Visually inspect the system daily prior to operating tractor. Be sure the
engine is level. Check the coolant level only when the system is cold.
Check the coolant level only at the overflow reservoir (Fig. 4-7). The
cooling system is a closed type. Never open the radiator cap. Doing so
may induce air into the cooling system and may cause overheating. The
coolant level should be between the “H” and “L” marks.
Super Z Diesel
DANGER: Never remove radiator cap or overflow reservoir
cap when engine is hot. Pressurized hot steam and water may
be released, causing serious burns or possible blindness.
Engine cooling is accomplished with circulated water and Ethylene
Glycol mixture. The radiator is equipped with a pressure cap and recovery
tank. A 50-50 mixture is recommended for all season operation. This
mixture provides freeze protection to -32 degrees F (-35 degrees C).
Should temperatures fall below this level, additional Ethylene Glycol must
be added to the mixture.
Visually inspect the system daily prior to operating tractor. Check
coolant level in the recovery tank located to the front left of the radiator
assembly (Fig. 4-8). When the engine is cold there should be 1” (2.54
CM )
of coolant in the recovery tank. When adding coolant, pre-mix the solution
before adding it to the recovery tank. It is not necessary to remove radiator
cap for adding small amounts of coolant to system.
