Reversing Fan Operation - Toro 31598 Operator's Manual

WARNING
This product is designed to drive objects into the
ground where they lose energy quickly in grass
areas. However, careless operation, combined with
terrain angle, ricochets, or improperly positioned
safety guard can lead to thrown object injuries.
• When a person or pet appears suddenly in or
near the mowing area, stop mowing .
• Do not resume mowing until the area is cleared.
Before stopping the engine, disengage all controls and
move the throttle to the slowest position. Moving the
throttle to the slowest position reduces high engine
speed (RPM), noise, and vibration. Turn the key to Off
to stop the engine.
Before transporting the machine, raise the cutting
units and secure the side cutting unit transport latches
(Figure 41).

Reversing Fan Operation

The fan speed will be controlled by hydraulic oil
temperature, air intake temperature and engine coolant
temperature. A reverse cycle is automatically initiated
and only happens when either the engine coolant
or hydraulic oil temperature reaches a certain point.
This reversal will help blow debris off the rear screen
and lower the engine and hydraulic oil temperatures
(Figure 42).
