Safety System
The Safety System of this Zero Turn Mower is designed
to prevent starting or driving the Zero Turn Mower under
the following conditions
.
The engine will only start when :
●
The Zero Turn Mower PTO Switch is in the down po-
sition (Blades disengaged).
●
Both Steering Levers are in the Neutral Lock Posi-
tion.
●
The Parking Brake is on
.
●
Operator in seat.
Make periodic checks of the Safety System by attempt-
ing to start the engine when one of these conditions are
not met.
If the engine starts when one of these conditions are not
met, shut the Zero Turn Mower down and repair the
safety system before using the Zero Turn Mower again.
Check to be sure the engine stops when the operator
leaves the seat when the Parking brake is OFF.
Check to be sure the engine stops when the Zero Turn
Mower blades are engaged and the operator leaves the
seat.
Check to be sure that engine stops if the Steering Levers
are moved from the Neutral Lock position with the Park-
ing Brake in the on position.

Parking Brake is applied
.
The Parking Brake is designed to hold the Zero Turn
Mower in place when all forward or reverse motion has
stopped.

or reverse travel and the Steering Levers in the op-
erating position will stop the engine and could do
possible damage to the Hydrostat Drives.

should be 35 Lbs.

to be moved up to remove slack in cable or down to
slightly relieve tension on brake.
