when one of the conditions is not met. Change
the conditions and try again.
If the machine starts when one of these
conditions is not met, turn the machine off and
repair the safety system before using the machine
again.
Make sure the engine stops when the park brake
is not engaged and the operator leaves the
seated position.
Check that the engine stops if the mower blades
are engaged and the driver temporarily moves off
the drivers seat.
IMPORTANT INFORMATION To be able to
drive, the driver must sit in the seat and the
steering / park brake controls must be moved
into the engaged (outer) position. Otherwise
the engine will stop.

Replace the steering boot, making sure the boot
top sits between the two adjustment bolts on the
steering control.
For any further adjust to the park brake, contact a
