S150X 21HP, 23HP, 25HP & 27HP - 48” & 52” Mower Deck
Check Deck Rod Timing
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 lift rod timing, measure and record the distance between the lift pivots and the rod pivots. Repeat for the other side of the machine. See Figure 15.
3.If the measurements for the 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.
4.Lock the deck lift pedal in the 5” (12,7cm) position. Remove the cutting height adjustment pin and lower the mower deck.
5.To ensure that the deck is in the lowest position, push the pedal by hand towards the rear of the machine and install the height adjustment pin in the 3” (7.6cm) position to hold in place.
6.Block up the mower deck until all hanger chains are slack. Refer to Figure 16.
7.See Figure 15. To adjust the lift rod, loosen the jam nut on the clevis then remove the 1/2” clevis pin fastening the clevis the the lift pivot arm. Turn the clevis clockwise to shorten the distance between the rod pivots or counterclockwise to lengthen the distance between the rod pivots. Reinstall the clevis on the lift pivot arm and secure with the 1/2” clevis pin previously removed. Tighten the jam nut against the clevis.
8.Remove the blocks from under the mower deck.
9.Remove the the cutting height adjustment pin from in front of the deck lift pedal arm. Lift the mower deck and reinstall the adjustment pin in the desired mowing height.
