The safety systems installed on your machine should be checked before each machine use. Be sure you have read the machine operator manual and are completely familiar with the operation of the machine before performing these safety system checks.

Use the following checkout procedures to check for normal operation of machine.

If there is a malfunction during one of these procedures, do not operate machine. See your authorized dealer for service.

Perform these tests in a clear open area. Keep bystanders away.

Testing PTO Switch

1.Sit on the operator seat with the motion control levers in the neutral detent position (standard levers) or neutral lock position (optional “over the lap” levers).

2.Lock the park brake.

3.Pull PTO knob up to engage.

4.Turn key switch to the start position.

Result: The engine must not crank.

Testing Park Brake Switch

1.Sit on the operator seat with the motion control levers in the neutral detent position (standard levers) or neutral lock position (optional “over the lap” levers).

2.Push PTO knob down to disengage.

3.Unlock the park brake.

4.Turn key switch to the start position.

Result: The engine must not crank.

Testing Neutral Start Switch

NOTE: Repeat this test three times, with the motion control levers in the following positions:

•Right side motion control lever inward.

•Left side motion control lever inward.

•Both motion control levers inward.

1.Move motion control lever(s) out of the neutral detent position (standard levers) or neutral lock position (optional “over the lap” levers).

2.Lock the park brake.

3.Push PTO knob down to disengage.

4.Turn key switch to the start position.

Result: The engine must not crank.

Testing Seat Switch

Procedure 1:

1.Sit on the operator seat with the motion control levers in the neutral detent position (standard levers) or neutral lock position (optional “over the lap” levers).

2.Unlock the park brake.

3.Push PTO knob down to disengage.

4.Turn key switch to the start position.

5.Raise slightly off the seat.

Result: The engine must stop.

Procedure 2:

1.Start engine.

2.Lock the park brake.

c CAUTION: Avoid injury! Before engaging mower, make sure that area is clear of bystanders, especially children.

3.Pull PTO knob up to engage.

4.Raise slightly off the seat. Result: The engine must stop.

Testing the Park Brake

MIF

1.Stop machine on a 17° slope (30% grade). Stop the engine and lock the park brake.

Result: Park brake must hold the machine stationary. (Machine should move no more that 61 cm (24 in.) in one hour.) If machine moves more than that, brakes need to be adjusted. See Adjusting Park Brake in the Service Steering & Brakes section.
