be trapped between the injection pump and
injectors; refer to Bleeding Air From the
Injectors.
Check Interlock Switch
Operation
CAUTION
Do not disconnect the safety switches because
they are for the operator's protection. Check
operation of the switches daily to be sure the
interlock system is operating correctly. If a
switch is not operating properly, replace it before
operating the machine. Replace the switches
every two years to be sure of maximum safety.
1. Make sure all bystanders are away from the
area of operation. Keep your hands and feet
away from the cutting units.

not start with either the deck switch engaged or
the traction pedal engaged. Correct the

in neutral, the parking brake off and the deck
switch in the OFF position, the engine should
start. Rise off the seat and slowly depress the
traction pedal, the engine should stop in one to

In case of emergency, the Groundsmaster can be
towed for a short distance. However, Toro does not
recommend this as a standard procedure.
IMPORTANT: Do not tow the machine faster
than 3–4 kmh because drive system may be
damaged. If the machine must be moved a
considerable distance, transport it on a truck or
trailer.
