j)Recheck that blocks fit just snugly under the deck skirt and that the tension on all the chains are approximately equal. Make sure all chain attachment bolts are tight.
k)Raise deck lift lever to the 4.5” (11.4 cm) cutting height position (also transport position, See Figure 6. Adjust spring compression until proper 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.
l)Reposition anti-scalp rollers and tighten securely.
NOTE: When above adjustments have been made, the front of the deck will be slightly lower than the rear of the deck.
4.2.3Pump Drive Belt Tension.
Self-tensioning - No adjustment necessary.
4.2.4Deck Belt Tension.
4.2.5Adjust 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
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.
4.2.6Park Brake Adjustment.
a)Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.
b)Check tire pressure. Inflate tires to 13 psi (90kpa).
c)Disengage the park brake.
d)Loosen the jam nuts next to the yoke at each end of the park brake linkage. See Figure 8.
e)Place a wrench on one of the two nuts near the front of the park brake linkage.
f)Turn the linkage until the distance from the lower front corner of the brake bar measures 1” (2.5 cm) to 1 5/16”(3.3 cm) with the park brake disengaged See Figure 8.
g)Tighten the jam nuts loosened in step d).
