Adjust Seat Switch
1. 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).
Normal adjustment is when length of spring is
2.09 inches (5.3 cm) (with seat up).
Note:
To prevent the engine from cutting out
when operating over rough ground, the unit is
equipped with a time-delayed seat switch. When
the operator raises off the seat with either the
brake disengaged or the PTO engaged, the engine
should stop after 1/2 second has elapsed.
2. To adjust seat switch actuator rod length, loosen
lock nut on bottom of the actuator rod (5/16
x 7 inch bolt) and adjust the nuts to move the
actuator plate/washer up or down on the rod,
then retighten.
Caster Pivot Bearings
Pre-Load Adjustment
Remove dust cap from caster and tighten nyloc nut
until washers are flat and back off 1/4 of a turn
to properly set the pre-load on the bearings. If
disassembled, make sure the spring disc washers are
reinstalled as shown in Figure 23.
