Troubleshooting, Adjustment & Service

 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 43.

 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 43.

 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.

 6.  To ensure that the deck is in the lowest position, 

push the pedal by hand towards the rear of the 
unit and install the height adjustment pin in the 3” 
(7.6cm) position to hold in place.  See Figure 41.

 7.  Block up the mower deck until all hanger chains 

are slack.

 8.  To adjust the inner rod: Loosen the jam nut (A, 

Figure 44) on the front ball joint (B) then remove 
the 1/2” hardware (C) fasten the ball joint to the lift 
pivot arm. Turn the ball joint clockwise to shorten 
the distance between the rod pivots or counter-
clockwise 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.  To adjust the outer rod: Loosen the jam nut (D) 

on the front ball joint (E) then remove the 1/2” 
hardware (F) fasten the ball joint to the lift pivot 
arm. Turn the ball joint clockwise to shorten 
the distance between the rod pivots or counter-
clockwise 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.

 10. Remove blocks from under the mower deck.

 11. While pushing the pedal by hand towards the 

rear of the unit, remove the the cutting height 
adjustment pin from in front of the deck lift pedal 
arm.  Lift mower deck and reinstall adjustment pin 
in desired mowing height.
