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.
