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 37.

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” (3,17mm) difference), adjustment is required, continue with Step 5.

5.Lock the deck lift pedal in the 5” (12,7cm) position. Remove the cutting height adjustment pin and lower the mower deck.

8.Refer to Figure 39. To adjust the inner lift rod, loosen the jam nut on the front ball joint then remove the 1/2” hardware fastening the ball joint the the lift pivot arm. Turn the ball joint clockwise to shorten the distance between the rod pivots or counterclockwise 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.

9.Refer to Figure 39. To adjust the inner lift rod, loosen the jam nut on the front ball joint then remove the 1/2” hardware fastening the ball joint the the lift pivot arm.
