Checking the Safety Interlock
System
CAUTION
If the safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
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 118-177 ml (4 to 6
ounces), the float switch in the tank will close. After a one
second delay, the alarm will sound, alerting the operator
(Figure 25). 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.
Before Starting (oil cold)
1. Filler cap
2. Filler neck
3. Overflow tube
4. Sight window
