Deck Rod Timing Adjustment
1. Park the machine on a flat, level surface.
Disengage the PTO, engage the parking brake,
turn off the engine and remove ignition key. Rear
tires must be inflated to 15 psi (1.03 bar); front
tires to 25 psi (1.72 bar).
2. To check the lift rod timing, measure and record
the distance between the lift pivots and the rod
pivots. Repeat for the other side of the unit. See
Figure 33.
3. If the measurements for the rods are equal,
no further adjustment is required. If the
measurements are not equal (greater than 1/8”
(3.17 mm) difference), adjustment is required,
continue with step #4.
4. Lock the deck lift pedal in the 5” (12.7 cm)
position. Remove the cutting height adjustment
pin and lower the mower deck.
5. To ensure that the deck is in the lowest position,
push the pedal by hand towards the rear of the
unit and install the height adjustment pin in the 3”
(7.6 cm) position to hold in place.
6. Block up the mower deck until all hanger chains
are slack. Refer to Figure 34.
7. See Figure 35. To adjust the lift rod, loosen the
jam nut on the clevis then remove the 1/2” clevis
pin fastening the clevis to the lift pivot arm. Turn
the clevis clockwise to shorten the distance
between the rod pivots. Reinstall the clevis on the
lift pivot arm and secure with the 1/2” clevis pin
previously removed. Tighten the jam nut against
the clevis.
8. Remove the blocks from under the mower deck.
9. Remove the cutting height adjustment pin from
in front of the deck lift pedal arm. Lift the mower
deck and reinstall the adjustment pin in the desired
mowing height.
Deck Leveling Adjustment
NOTE: Before adjusting the deck level, the deck lift
rod timing must be checked and/or adjusted.
1. Park the machine on a flat, level surface.
Disengage the PTO, stop the engine and engage
the parking brake. Rear tires must be inflated to
15 psi (1.03 bar); front tires to 25 psi (1.72 bar).
2. Lock the deck lift pedal in the 5” (12.7 cm)
position. Place the deck height adjustment pin in
the 4” position and lower the deck lift pedal until
the arm contacts the pin.
3. Place 2 x 4 blocks under each corner of the
mower deck with the 3-1/2” sides being vertical.
See Figure 34.
4. Adjust the front eyebolts until the chains are tight
and the deck is resting on the 2 x 4’s. Tighten the
jam nuts. See Figure 36.
5. Loosen the nuts and allow the rear of the deck to
rest on the 2 x 4’s. Slide the chains down in the
slots until the chains are tight and tighten the nuts.
See Figure 36.
6. Remove all 2 x 4 blocks from under the mower
deck.
