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.
