DECK LIFT ROD TIMING
ADJUSTMENT
1. Park machine on a flat, level surface. Disengage
the PTO, stop the engine and engage the parking
brake. Rear tires must be inflated to 18 psi (1,24
bar); front tires to 25 psi (1,72 bar).
2. To check the inner lift rod timing, measure and
record the distance between the inner lift pivots
and the inner rod pivots. Repeat for other side of
unit. See Figure 39.
3. To check the outer lift rod timing, measure and
record the distance between the outer lift pivots
and the outer rod pivots. Repeat for other side of
unit. See Figure 39.
4. If the measurements for the inner rods are equal,
and the measurements for the outer rods are
equal, no further adjustment is required. If the
measurements are NOT equal (greater than 1/8”
(3,17mm) difference), adjustment is required,
continue with Step 5.
5. Lock the deck lift pedal in the 6” (15,2cm) position.
Remove the cutting height adjustment pin (A,
Figure 40) and lower the mower deck.
6. 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”
(7.6cm) position to hold in place.
7. Block up the mower deck until all hanger chains
are slack.
8. Refer to Figure 41. To adjust the inner lift rod,
loosen the jam nut on the front ball joint then
remove the 1/2” hardware fastening the ball joint
the the lift pivot arm. Turn the ball joint clockwise
to shorten the distance between the rod pivots
or counterclockwise 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.
9. Refer to Figure 41. To adjust the inner lift rod,
