Note: Both of the front swivels need to be adjusted the
same amount to maintain equal chain tension.
7. Loosen the front swivel jam nuts, at the front of the
right and left swivels, approximately a 1/2 inch
(13 mm) (Fig. 68).
8. Adjust the lift nuts on both the left and the right side of
the machine to achieve 1/4 to 3/8 inch (6 to 10 mm)
lower in front at A than in the rear at B (Fig. 68).
9. Tighten both swivel jam nuts against the front swivel
to lock the height.
10. Check to make sure there is equal tension on the
chains and adjust again if needed.
Adjusting the Compression Spring
1. Raise the mower lift lever to the transport position
(Fig. 16).
2. Check the distance between the two large washers, it
needs to be 11–1/2 inches (29.2 cm) (Fig. 68).
3. Adjust this distance, by loosening the spring jam nut
and turning the nut in front of each spring (Fig. 68).
Turning the nut clockwise will shorten the spring;
counter–clockwise will lengthen the spring.
4. Lock the nut into position by tightening the spring jam
nut (Fig. 68).

2. Disengage the PTO, move the motion control levers to
the neutral locked position and set the parking brake.
3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Raise the mower to the transport position.
5. Lift the front of the machine and support the machine
using jack stands.
Mechanical or hydraulic jacks may fail to support
the machine and cause a serious injury.
• Use jack stands when supporting the machine.
