The Safety Interlock System

If safety interlock switches are disconnected
or damaged the machine could operate
unexpectedly causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock
switches daily and replace any damaged
switches before operating the machine.
The safety interlock system is designed to prevent the
engine from starting when:
• The blade control lever (PTO) is engaged.
• The ignition key is off.
The safety interlock system is also designed to stop the
engine when:
• The blade control bail is released with the blade
control lever (PTO) engaged.
• The ignition switch is turned to the off position.
Testing the Safety Interlock System
Test the safety interlock system before you use the
machine each time. If the safety system does not
operate as described below, have an Authorized Service
Dealer repair the safety system immediately.
1. Set the parking brake, disengage the PTO and place
the throttle forward.
2. Start the engine.
3. With the engine running squeeze the blade control
bail against upper control bar and push the mower
blade control lever forward. The mower blades
begin rotating.
4. With the engine running, release the blade control
bail. The engine should stop.
5. Start the engine again.
6. With the engine running, turn the key switch to the
off position. The engine should stop.

Driving Forward or Backward

The throttle control regulates the engine speed as
measured in RPM (revolutions per minute). Place the
throttle control in the fast position for best mowing
performance.
Driving Forward
1. To go forward, move the shift lever to a forward
gear (Figure 9).
2. Release the parking brake; refer to Releasing the
Parking Brake.
3. Slowly press on the upper control bar to move
forward (Figure 9).
To go straight, apply equal pressure to both ends of
the upper control bar (Figure 9).
To turn, release pressure on the upper control bar
side in the direction you want to turn (Figure 9).

Using the Lower Control Bar

This procedure is for driving up a curb. This can be
performed while driving forward or backward.
Note: Some curbs do not allow the rear drive tires to
contact the curb. If this happens, drive the machine up
the curb at an angle.
