5.2.6Adjust Seat Switch

a)If necessary, adjust the seat actuator rod length to where the machine will shut off when the operator raises off the seat (with brake disengaged or PTO engaged) but will continue to run with operator in seat (a slight shift in weight should not shut machine off).

For all units except Kohler EFI (seat spring mount weldment is painted black): Normal adjustment is when length of spring is 2.09” (5.3 cm) (with seat up).

For Kohler EFI units (seat spring mount weldment is yellow plated): Normal adjustment is when length of spring is 2.50” (6.4 cm) (with seat up).
