NOTE: Threading the ball joints too far on to 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:
1.
Place the steering wheel in position for straight ahead travel.
2.
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.
3.
Behind the axle, measure the distance horizontally from inside of the left rim to the inside of the right rim. Note
the distance.
4.
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.
Leveling the Deck
NOTE: Check the tractor’s tire pressure before performing any deck leveling adjustments. Refer to Tires later in this
section for further information regarding tire pressure.
Front To Rear
The front of the cutting deck is supported by a stabilizer
bar that can adjusted to level the deck from front to rear.
The front of the deck should be between 1/4-inch and
3/8-inch lower than the rear of the deck. Adjust if
necessary as follows:
1.
With the tractor parked on a firm, level surface, place
the deck lift lever in the top notch (highest position)
and rotate the blade nearest the discharge chute so
that it is parallel with the tractor.
2.
Measure the distance from the front of the blade tip to
the ground and the rear of the blade tip to the ground.
The first measurement taken should be between 1/4"
and 3/8" less than the second measurement.
Determine the approximate distance necessary for
proper adjustment and proceed, if necessary, to the
next step.
3.
Locate the two lock nuts on the opposite side of the
stabilizer bracket. See Figure 6. Tighten the lock nuts
to raise the front of the deck; loosen the lock nuts to
lower the front of the deck.
Side to Side
If the cutting deck appears to be mowing unevenly, a side
to side adjustment can be performed. Adjust if necessary
as follows:
1.
With the tractor parked on a firm, level surface, place
the deck lift lever in the top notch (highest position)
and rotate both blades so that they are perpendicular
with the tractor.
2.
Measure the distance from the outside of the left
blade tip to the ground and the distance from the
outside of the right blade tip to the ground. Both
measurements taken should be equal. If they’re not,
proceed to the next step.
3.
Loosen, but do not remove, the hex cap screw on the
left deck hanger bracket. See Figure 7.
4.
To balance the deck turn the adjustment gear, located immediately behind the hex cap screw, clockwise/up or
counterclockwise/down. See Figure 7. You will need an adjustable wrench for this step.
5.
The deck is properly balanced when both blade tip measurements, taken earlier, are equal.
6.
Retighten the hex cap screw on the left deck hanger bracket when proper adjustment is achieved.
