•
Looking at the transmission from the right side of
the tractor, locate the compression spring and
brake disc. See Figure 10.
Figure 10
•
Loosen, but do NOT remove, the hex nut found on
the right side of the brake assembly. See Figure 10.
•
Using a feeler gauge, set the gap between the
brake disc and the brake puck at .011".
•
Re-tighten the hex nut loosened earlier.
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.
•
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.
Figure 11
•
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.
SECTION 7: MAINTAINING YOUR LAWN TRACTOR
WARNING:
Before performing any
maintenance or repairs, disengage PTO,
move shift lever into neutral position, set
parking brake, stop engine and remove key to
prevent unintended starting.
Cleaning the Engine And Deck
Any fuel or oil spilled on the machine should be wiped
off promptly. Do NOT allow debris to accumulate
around the cooling fins of the engine or on any other
part of the machine, especially the belts, pulleys and
other moving parts. Clean the underside of the deck
with a wisk broom, scraper or forced air after each
mowing.
IMPORTANT:
The use of a pressure washer or garden
hose to clean your tractor is NOT recommended. It may
cause damage to electrical components, spindles,
pulleys, bearings or the engine. The use of water will
result in a shortened life of the tractor and reduce its
serviceability.
