Mower Deck Adjustment - 61" Mower Decks
Adjusting the Deck Lift Rod Timing
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. To check the deck lift rod timing, measure and record
the distance between the lift pivots and the rod pivots.
Repeat for other side of unit. See Figure 43.
3. If the measurements are equal, skip to Adjusting the
Leveling of the Mower Deck. 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. See Figure 44.
6. Block up the mower deck until all hanger chains are
slack. See Figure 45.
7. Refer to Figure 46. To adjust the deck lift rod, loosen
the jam nut on the front ball joint then remove the 1/2"
hardware fastening the ball joint to the lift pivot arm.
Turn the ball joint clockwise to shorten the distance
between the rod pivots or counter-clockwise to lengthen
the distance between the rod pivots. Reinstall the ball
joint on the lift pivot arm and secure with the 1/2"
hardware previously removed. Tighten the jam nut
against the lift rod.
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 mower deck and reinstall
adjustment pin in desired mowing height.
