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.Install the cutting height adjustment pin in the 3- 3/4” (9,5 cm) position. See Figure 38.

3.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 39.

4.If the measurements for the rods and pivots 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.Refer to Figure 39. To adjust the lift rods, adjust the 5/8” hex nuts on either side of the front lift pivot until the measurements are equal. Repeat for other side. Make sure the nylon lock nut on the end of the rod towards the rear of the machine is loose to allow the rod to turn in the rear lift pivot.

6.Refer to Figure 40. Measure the distance from the front lift pivot to the ground and from the front chain anchor bolt to the ground. If the measurements 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 7.

7.Raise the seat plate to access the center lift link (A, Figure 41).

8.Loosen the jam nut (C) on the lift clevis (D) and turn the adjuster bolt (B) until the measurements are equal. Tighten the jam nut against the lift clevis.
