Troy-Bilt RZT manual Leveling the Mower Deck, Side to Side Leveling, Front to Back Leveling

•Tighten the flange lock nut to fix the control lever in the adjusted position

•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 inch 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:

•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.

•Lower the deck to the middle height position.

•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.

•Comparing the two measurements, determine whether the left side of the deck must be raised or lowered.

•Loosen, but do not remove, the hex cap screw on the left deck hanger bracket. See Figure 6-6.

•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 Figure 6-6.

•The deck is properly leveled when left and right blade tip measurements are equal.

•Retighten the hex cap screw on the left deck hanger bracket when proper adjustment is achieved.

Front to Back Leveling.

The front of the deck should be approximately 1/4 inch lower than the rear of the deck. Adjust if necessary as follows:

•With the deck raised off of the ground, rotate the outer blades so that they are parallel to the frame of the tractor.

•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.

•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 inch less than the rear. If it is not, proceed to the next step.

•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 Figure 6-7.

•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 Figure 6-7.

•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.

IMPORTANT: 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.

•When the correct pitch of the deck is acquired, secure the inner hex nuts with a wrench and tighten the outer hex nuts against the inner hex nuts to lock them in the adjusted position.
