on all the chains are approximately equal. Make sure all chain attachment
bolts are tight.

distance is obtained between the two washers (See Figure 7) by turning the
nut at the front of each spring. Lock nuts in position with jam nuts.

4.2.5 Adjust 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). Normal adjustment is when length of
spring is 2.09” (5.3 cm ) (with seat up).

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.
b) To adjust seat switch, loosen lock nut on bottom of the actuator rod (5/16 x 7”
bolt) and adjust the nuts to move the actuator plate up or down on the rod.
