Verify Interlock Operation

The interlock system is designed to stop the engine when the operator is off of the seat, while the traction selector is in the No. 1 or No. 2 position or the mow pedal is pushed down. The system also prevents the engine from starting in the same situation.

CAUTION

Do not disconnect or bypass the interlock switches. Check the operation of the switches to assure that the interlock system is operat- ing correctly. If a switch is malfunctioning or out of adjustment, adjust or replace it before operating the machine. To assure maximum safety, replace all interlock switches every two years or 1000 hours, whichever comes first.

To check the operation of the interlock switches:

1.Set on the seat and engage the parking brake. Push the lift pedal down all the way and release it. Move the shift selector to the No. 1 position and try to start the engine. The engine should not crank. Move the shift selector to the No. 2 position and try to start the engine. The engine should not crank. If the engine did not crank in either position, the traction switch is operating prop- erly – proceed to step 2. If the engine cranked, refer to Troubleshooting in this chapter.

2.Sit on the seat and engage the parking brake. Push the lift pedal down all the way and release it. Move the

shift selector to the neutral (N) position and try to start the engine. The engine should start and continue to run, which means that the traction switch and mow/lift switch is operating correctly - proceed to step 3. If the engine cranked, but did not start, the problem is not in the interlock system. If the engine did not crank, refer to Troubleshooting in this chapter.

3.Sit on the seat and engine the parking brake. Move the shift selector to the neutral (N) position. Push the mow pedal down and try to start the engine. The engine should not crank, which means the mow/lift switch is operating correctly - proceed to step 4. If the engine cranked, refer to Troubleshooting in this chapter.

4.Sit on the seat and engage the parking brake. Move the shift selector to neutral (N). Push lift pedal down and release it. Start the engine, release the parking brake and drive the machine to an open area that is free of debris and foreign objects. Keep all people, especially children away from the front of the machine and out of the area of operation. Move shift selector to neutral (N), make sure the mow pedal is disengaged, set the throttle control at half speed and engage the parking brake. Hold the steering wheel, brace your feet on the foot deck and brake pedal, and move the shift selector to the No.

1position. Carefully lift off the seat; the engine should stop. Repeat procedure with shift selector in No. 2 position. If engine stops while lifting off the seat with shift selector in No. 1 and No. 2 positions, interlock system is operating correctly. If engine does not stop, stop the engine and correct the problem before operating the machine. Refer to Troubleshooting in this chapter.
