Deck Lift Rod Timing Adjustment
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).
2. Measure and record the distance between the lift
pivots and the rod pivots. Repeat for the other
side of the unit. See Figure 35.
3. If the measurements for the lift pivots and rod
pivots 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. Lower the mower deck to the lowest cutting
position.
5. Block up the mower deck until all of the hanger
chains are slack. See Figure 36.
6. Refer to Figure 37. To adjust the 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.
7. Remove the blocks from under the mower deck.
8. Adjust the cutting height to the desired position.
