Deck Wheels
The wheels on the deck are equipped with a grease fitting. Lubricate with a No.
2 multi-purpose grease applied with a grease gun after every 25 hours of tractor
operation.
Pivot Points & Linkage
Lubricate all the pivot points on the drive system, parking brake and lift linkage at
least once a season with light oil.
Note: It is not necessary to grease the steering pinion/sector gear interface. Doing
so will allow dirt to accumulate and can affect steering performance.
Adjustments
Shut the engine off, remove the ignition key and engage the parking brake
before making adjustments. Protect your hands by using heavy gloves
when handling the blades.
NOTE : Check the tractor's tire pressure before performing any deck leveling
adjustments. Refer to Tires on page 11 for information regarding tire pressure.
Adjusting the Deck
Leveling the Deck (Front-To-Rear)
The front of the cutting deck is supported by a stabilizer bar that can be adjusted to
level the deck from front to rear. The front of the deck should be between 1⁄ 4 -3⁄8"
lower than the rear of the deck. Adjust if necessary as follows:
1.
Park the tractor on a firm, level surface and place the deck lift lever in the
middle 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 front of the deck should be between
1⁄4-3⁄8" less than the rear of deck.
3.
Determine the approximate distance necessary for proper adjustment and
proceed, if necessary.
4.
To raise the front of the deck, loosen the outer nut then tighten (thread
inward) the nut against the front hanger bracket. See Figure 22. When
proper adjustment is achieved, re-tighten the outer nut to 25-30 ft.-lbs.
SERVICE AND MAINTENANCE
WARNING
Figure 22
5.
To lower the front of the deck, loosen the outer nut then loosen (thread
outward) the nut, away from the front hanger bracket. See Figure 22. When
proper adjustment is achieved, re-tighten the outer nut.
Leveling 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 middle 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.
Under the rear fenders inside the wheels there is a lift adjustment rod for
each side of the deck. See Figure 23.
4.
Minor side-to-side adjustments should be made using primarily the left
adjustment rod.
5.
To raise the left side of the deck, loosen the upper nut on the end of the
lift rod, then turn the lower nut clockwise. When the proper adjustment is
achieved, tighten the upper nut to secure in place. To lower the left side of
the deck, loosen the upper nut on the end of the lift rod, then turn the lower
nut counterclockwise. When the proper adjustment is achieved, tighten the
upper nut to 25-30 ft-lbs. to secure in place.
6.
The deck is properly leveled when both blade tip measurements taken earlier
are equal.
Adjusting the Deck Height
The height of the deck can be adjusted to ensure that the setting on your deck
height lever is accurate. To adjust the deck height proceed as follows:
1.
Park the tractor on a firm, level surface and place the deck lift lever in the
highest position (4") and rotate the blade nearest the discharge chute so that
it is 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
23
measurements taken should be 4". If they're not, proceed to the next step.
