Leveling The Mower Deck - Cub Cadet RZT54 Operator's Manual

To adjust the drive control levers forward or rearward, proceed as
follows:
If not already loose, loosen the flange lock nut and rotate
the control lever either forward or rearward to the desired
position. See Fig. 6-6.
NOTE: If the control lever is too tight to move, slightly
loosen the hex insert flange lock nut and shoulder screw at
the bottom of the control lever.
2. Tighten the flange lock nut to fix the control lever in the
adjusted position
3. Repeat the above procedure to adjust the other control
lever into the same position. Adjust so that both levers are
even with each other when in the neutral position.
leveling the Mower Deck
When correctly adjusted the mower deck should be level side to
side, and the front of the deck should be approximately 1/4"lower
than the rear of deck.
NOTE: Check the tractor's tire pressure before performing any
deck leveling adjustments. See the tire side wall for proper
inflation pressures.
Side to Side Leveling
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 handle in the top notch (highest position) and
rotate both outer blades so that they are perpendicular to
the tractor frame.
2. Lower the deck to the middle height position.
3. Measure the distance from the outside left blade tip to the
ground and the distance from the outside right blade tip to
the ground. The measurements should be equal. If they're
not, proceed to the next step.
4. Comparing the two measurements, determine whether the
left side of the deck must be raised or lowered.
5. Loosen, but do not remove, the hex cap screw on the left
deck hanger bracket. See Fig. 6-7.

Level the deck by using a wrench to turn the adjustment
gear (found immediately behind the hex cap screw just
loosened) clockwise to raise the left side of the deck, or
counterclockwise to lower the left side of the deck. See Fig.
6-7.
7. The deck is properly leveled when left and right blade tip
measurements are equal.
8. Retighten the hex cap screw on the left deck hanger
bracket when proper adjustment is achieved.
Front to Back Leveling.
1. The front of the deck should be a pproximately 1/4"lower
than the rear of the deck. Adjust if necessary as follows:
2. With the deck raised off of the ground, rotate the outer
blades so that they are parallel to the frame of the tractor.
3. If the side to side leveling was done correctly, measuring
just the right blade should be acceptable to attain the
correct back to front pitch of the deck.
4. Measure the distance from the front tip of the blade to the
ground and the distance from the rear tip to the ground.
The front distance should be approximately 1/4"less than
the rear. If it is not, proceed to the next step.
5. From the front of the tractor, loosen the outer hex nuts on
the deck front hanger rod and turn them away from the
inner nuts. Refer to Fig. 6-8.

6. If the front of the deck was too low, turn the inner hex nuts
clockwise against the hanger bracket to shorten the front
hanger rod and raise the front of the deck. Refer to Fig. 6-8.
7. If the front of the deck was too high, turn the hex nuts
counterclockwise to lengthen the front hanger rod and
lower the front of the deck.
NOTE:The deck front hanger rod should be at the front of
the slots of the front deck bracket. If one side of the rod is
not at the front of its slot, turn the inner hex nut on that
side until rod just touches the front of the slot. Then re-
measure and re-adjust the front hanger rod as necessary.
