To inspect the safety start interlock system:
1. Park the unit on a flat, level surface.
2. The operator must be on the seat when testing the seat
switch.
3. Engage the park brake.
4. Start the engine and allow it to warm up to operating
temperature.
5. With the PTO disengaged, slowly raise off of the seat.
The engine should continue to run.
6. Disengage the park brake and with the PTO
disengaged, slowly raise off of the seat. The engine
should stop.
7. Engage the park brake and the PTO, slowly raise off of
the seat. The engine should stop.
8. If the engine fails to stop and the operator is off the
seat, check the function of the seat switch. If the seat
switch is not operating properly (is not opening or
closing) and if the cause can not be determined, replace
the seat switch.
If the problem can not be located, contact your Hustler
Dealer.
WARNING: The safety interlock system should
always function per steps 2 thru 6. If it does not
function properly, it should be corrected immedi-
ately. Do not operate machine without properly
functioning seat safety switch.
PTO stop system:
While operating PTO driven equipment, the PTO will
disengage automatically when the equipment is raised by the
lift control lever to the maximum lift height.
NOTE: The PTO control lever remains in the engaged
position after activating the PTO stop device (the PTO shaft
will no longer rotate). To re-engage the PTO, the PTO control
lever must be moved to the “OFF” position, then pushed for-
ward again.
To inspect the PTO stop system:
1. The operator must be on the seat when testing the PTO
switch.
WARNING: Perform this test in an area free of any
bystanders.
2. Set the park brake.
3. Start the engine and allow it to warm up to operating
temperature.
4. With the PTO engaged, slowly raise the attachment
using the Tool Bar Lift Control Lever. The PTO
should stop when the attachment is raised to it’s
maximum lift height.
