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.
Leveling the Deck
NOTE: 
Check the tractor’s tire pressure before
performing any deck leveling adjustments. Refer to
Tires on page 24 for 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:
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.
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. 
Loosen the two jam nuts on the rear side of the 
deck stabilizer bracket. See Figure 11Figure 11A.
Locate the two lock nuts on the opposite side of the 
stabilizer bracket. See Figure 11Figure 11A. 
Tighten the lock nuts to raise the front of the deck; 
loosen the lock nuts to lower the front of the deck.
Retighten the two jam nuts loosened earlier when 
proper adjustment is achieved.
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:
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.
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.
Loosen, but do NOT remove, the hex cap screw on 
the left deck hanger bracket. See Figure 11B.
Balance the deck by using a wrench to turn the 
adjustment gear (found immediately behind the hex 
cap screw just loosened) clockwise/up or 
counterclockwise/down.
The deck is properly balanced when both blade tip 
measurements taken earlier are equal.
Retighten the hex cap screw on the left deck 
hanger bracket when proper adjustment is 
achieved.
