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

bolts are tight.

transport position, See Figure 9. Adjust spring compression until proper

distance is obtained between the two washers (See Figure 11) by turning

the nut at the front of each spring. Lock nuts in position with jam nuts.

5.2.5 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).

NOTE: To prevent rough ground cut-outs 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.

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.
