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.
