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
The Zero Turn Mower must be standing still when
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.
NOTE: Applying the parking brake while in forward
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.
Tire Pressure
All tire pressure should be at
15psi / 103kPa / 1 bar
Parking Brake Adjustment
Adjusting the Parking Brake Link-
age will require working under the
Zero Turn Mower. Before working
under the Zero Turn Mower chock the wheels so the ma-
chine cannot move.
1. Release the Parking Brake.
2. Loosen the Rear Adjusting Nut, Front Adjusting Nut
and the Locknuts.
3. Adjust the Rear Boss so the center is 1.25” from the
end of the Brake Rod. Tighten the Rear Adjusting Nut
and Locknuts against the Rear Boss to maintain this
location.
4. Adjust the distance between the Rear Boss and the
Front Boss so the distance is 12” between centers.
5. The distance from the center of the Front Boss to the
end of the Brake Rod should now measure 4.5”.
6. Turn the Front Adjusting Nut and Flatwasher against
the spring until the spring side Flatwasher is .75” from
the end of the Brake Rod.
