Checking The Leak Detector - Toro Greensmaster
3150 Operator's Manual

The purpose of the safety interlock system is to prevent
operation of the machine where there is possible injury to
the operator or the machine.
The safety interlock system prevents the engine from
starting unless:
• The traction pedal is in neutral.
• The functional control lever is in neutral.
The safety interlock system prevents the machine from
moving unless:
• The parking brake is off.
• The operator is seated.
• The functional control lever is in Mow or Transport.
The safety interlock system prevents the reels from
operating unless the functional control lever is in the Mow
position.
Perform the following system checks daily to be sure the
interlock system is operating correctly:
1. Sit on the seat, move the traction pedal to Neutral, move
the functional control lever to Neutral, and engage the
parking brake. Try to depress the traction pedal. The
pedal should not depress, which means that the
interlock system is operating correctly. Correct the
problem if it is not operating properly.
2. Sit on the seat, move the traction pedal to Neutral, move
the functional control lever to Neutral, and engage the
parking brake. Move the functional control lever to
mow or transport and try to start the engine. The engine
should not crank, which means that the interlock system
is operating correctly. Correct the problem if it is not
operating properly.
3. Sit on the seat, move the traction pedal to Neutral, move
the functional control lever to Neutral, and engage the
parking brake. Start the engine and move the functional
control lever to mow or transport. The engine should
kill, which means that the interlock system is operating
correctly. Correct the problem if it is not operating
properly.
4. Sit on the seat, move the traction pedal to Neutral, move
the functional control lever to Neutral, and engage the
parking brake. Start the engine. Release the parking
brake, move the functional control lever to mow, and
rise from the seat. The engine should kill, which means
that the interlock system is operating correctly. Correct
the problem if it is not operating properly.
5. Sit on the seat, move the traction pedal to Neutral, move
the functional control lever to Neutral, and engage the
parking brake. Start the engine. Move the raise/lower
mow control forward to lower the cutting units. The
cutting units should not start rotating. If they do, the
interlock system is not operating correctly. Correct the
problem.

Checking the Leak Detector

The leak detector system is designed to assist in early
detection of hydraulic oil system leaks. If the oil level in
the main hydraulic reservoir, is lowered by 4 to 6 ounces
(118–177 ml), the float switch in the tank will close. After a
one second delay, the alarm will sound, alerting the
operator (Fig. 27). Expansion of oil, due to normal heating
during machine operation, will cause the oil to transfer into
the auxiliary oil reservoir. The oil is allowed to return to the
main tank when the ignition switch is turned off.
