Deck Lift Rod Timing Adjustment
Checking the 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 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 40.
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 40.
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” (3,17 mm) difference),
adjustment is required, continue with Adjusting the Deck
Lift Rod Timing.
