Verify Interlock System Operation

The machine has interlock switches in the electrical sys­
tem. These switches are designed to stop the engine
when operator gets off the seat when traction pedal is
depressed. However, operator may get off the seat while
engine is running. Although engine will continue to run if
PTO switch is disengaged and traction pedal is re­
leased, it is strongly recommended that the engine be
stopped before dismounting from the seat.
CAUTION
Do not disconnect the interlock switches.
Check operation of switches daily to assure in-
terlock system is operating correctly. If a
switch is malfunctioning, replace it before op-
erating the machine. To ensure maximum safe-
ty, replace all switches after every two years or
1000 hours, whichever comes first.
Groundsmaster 3000/3000–D
To check operation of interlock switches:
1. Drive the machine slowly to a large, relatively open
area. Lower cutting unit, stop the engine and apply park­
ing brake.
2. Sit on seat. Depress the traction pedal. Try to start
the engine. The engine should not crank. If the engine
cranks, there is a malfunction in the interlock system that
should be corrected before beginning operation.
Do not operate machine without implement
unless the PTO driveshaft is also removed.
3. Sit on seat and start the engine. Raise off the seat and
move the PTO lever to ON. The PTO should not engage.
If the PTO engages, there is a malfunction in the inter­
lock system that should be corrected before beginning
operation.
