Troubleshooting, Adjustment & Service
Deck Lift Rod Timing Adjustment (S/N:
2016270589 & Above)
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 15 psi (1,03
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 43.
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 43.
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 5” (12,7cm) position.
Remove the cutting height adjustment pin 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. See Figure 41.
7. Block up the mower deck until all hanger chains
are slack.
8. To adjust the inner rod: Loosen the jam nut (A,
Figure 44) on the front ball joint (B) then remove
the 1/2” hardware (C) fasten 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.
9. To adjust the outer rod: Loosen the jam nut (D)
on the front ball joint (E) then remove the 1/2”
hardware (F) fasten 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.
10. Remove blocks from under the mower deck.
11. While pushing the pedal by hand towards the
rear of the unit, remove the 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.
