Check operator presence controls:
WARNING : PREVENT ACCIDENTS - Keep bystanders away when checking operator
presence control interlock switches. DO NOT use the mower unless the operator presence con-
trols work correctly as described below. If difficulties arise, consult your "Hayter dealer”.
Operator presence seat switch: Sit on the operator seat and start the engine. Lower the cutterheads
to the ground and engage the cutter drive in the forward direction. Rise from the operators seat and
check that the cutting cylinders come to a stop after an initial 0.5 to 1 second delay. Repeat with the
cutting cylinders running in reverse.
Cutter drive interlock switch: Stop the mower engine. Operate the cutter drive switch to the ‘off’
position and turn the ignition key to position ‘I’. The cutterhead drive switch indicator light should illu-
minate. Refer - OPERATING THE MOWER.
Operate the switch to the ‘forward’ position. The indicator light should go out and the engine should
not start when the ignition key is turned. Repeat for the ‘reverse’ position.
Parking brake interlock switch: Stop the engine. Engage the parking brake and turn the ignition key
to position ‘I’. The parking brake indicator light should illuminate. Refer - OPERATING THE
MOWER.
Disengage the parking brake. The indicator light should go out and the engine should not start when
the ignition key is turned.
Transmission neutral interlock switch: Stop the mower engine and remove the foot from the for-
ward/reverse travel pedals. Turn the ignition key to position 'I’ and the transmission neutral indicator
light should illuminate. Application of light pedal pressure in a forward and reverse direction should
cause the indicator light to go out. Take extreme care to ensure that the area around the mower is clear
before checking that the engine will not start under this condition.
