Standard Seat
To adjust the position of the seat on models not
equipped with a seat adjustment lever, loosen, but do
NOT remove the four screws which secure the seat to
the seat pivot bracket. Slide the seat forward or
backward until desired position is reached. Retighten
the four screws. See Figure 10.
Figure 10
Steering Adjustment
If the tractor turns tighter in one direction than the other,
or if the ball joints are being replaced due to damage or
wear, the steering drag links may need to be adjusted.
Adjust the drag links so that equal lengths are threaded
into the ball joint on the left side and the ball joint on the
right side:
•
Loosen the jam nut found on the drag link at the
rear of the ball joint. See Figure 11.
Figure 11
•
Remove the hex nut and lock washer on the top of
ball joint. See Figure 11.
•
Thread the ball joint toward the jam nut to shorten
the drag link. Thread the ball joint away from the
jam nut to lengthen the drag link.
•
Replace hex nut and lock washer and retighten the
jam nut after proper adjustment is achieved.
NOTE:
Threading the ball joints too far onto the drag
links will cause the front tires to "toe-in" too far. Proper
toe-in is between 1/16" and 5/16".
Front tire toe-in can be measured as follows:
•
Place the steering wheel in position for straight
ahead travel.
•
In front of the axle, measure the distance
horizontally from the inside of the left rim to the
inside of the right rim. Note the distance.
•
Behind the axle, measure the distance horizontally
from the inside of the left rim to the inside of the
right rim. Note the distance.
•
The measurement taken in front of the axle should
be between 1/16" and 5/16" less than the
measurement taken behind the axle. Adjust if
necessary.
Deck Roller Height Adjustment
(Units with a 54-inch Deck)
To adjust the height of the rollers on the rear of the
mowing deck, proceed as follows:
•
Place the deck lift lever in the bottom notch (lowest
position).
•
Remove the clevis pins and hairpin clips from the
deck roller brackets on the left and right sides of the
cutting deck. See Figure 12.
