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 the ignition key. Rear tires must be inflated to
15 psi (1,03 bar); front tires to 40 psi (2,76 bar).
2. To check the lift rod timing, measure and record the
distance between the lift pivots and the rod pivots.
Repeat for other side of unit. See Figure 36.
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 4-1/2” (11,47 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 38.
7. See Figure 37. To adjust the lift rod, loosen the jam
nut on the front 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
or counterclockwise to lengthen 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 the under the mower deck.
9. Remove the cutting height adjustment pin from in front
of the deck lift pedal arm. Lift mower deck and reinstall
adjustment pin in desired mowing height.
Deck Leveling Adjustment
NOTE: Before adjusting the deck level, the deck lift rod
timing muyst 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. Check the tires from proper inflation levels. See
Checking Tire Pressures .
2. Lock the deck lift pedal in the 4-1/2” (11,47 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” side being vertical. Place a 1/4” (0,64
cm) thick spacer on top of the rear 2 x 4 blocks. See
Figure 38.
4. Adjust the front eyebolts until the chains are tight and
the deck is still resting on the 2 x 4 blocks. Tighten the
jam nuts. See Figure 39.
5. Loosen the nuts and allow the rear of the deck to rest on
the 2 x 4’s and 1/4” spacers. Slide the chains down in
the slots until the chains are tight and tighten the nuts.
See Figure 39.
6. Remove all 2 x 4 blocks and spacers from under the
mower deck.
