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
