To adjust the neutral setting for no wheel rotation Model IZT 915055, 057, 059, 067, 501:

1.Use a hex wrench to loosen the locking bolt (Figure 12).

2.With the engine running and the drive wheels off the ground rotate the linkage in either direction. The correct linkage position is when the wheel is not being driven (under power).

3.Hold the linkage in place and tighten the locking bolt.

4.Shut off engine.

5.To reconnect the steering rod it should be positioned through the hole in the trunnion. Two jam nuts are above and one nyloc nut is below the trunnion.

6.Without moving the transmission linkage turn the first jam nut towards the trunnion until it makes contact.

7.The nyloc nut is turned toward the trunnion until tight.

8.Move the second jam nut to contact the first jam nut and tighten together.

9.Reconnect parking brake pin.

4.10ADJUSTING THE UNIT TO TRACK STRAIGHT

Model EZT 915065, 502 with serial numbers above 10,000

(Figure 13)

IMPORTANT: The unit should track within 2 feet (0.61 m) of a straight line for 30 feet (9.14 m).

The travel of the steering levers may need adjustment if:

•The unit turns to the right or left when both steering levers are pushed as far forward as possible.

•The unit turns to the right or left when both steering levers are pulled back as far rearward as possible.

NOTE: The side the unit turns toward indicates that the wheel on that side is turning slower than the other wheel. Either the wheel that is turning faster needs to slow down or the wheel that is turning slower needs to be sped up to allow the unit to travel in a straight line.

See steering section for illustrations.

1.Determine which way the unit turns.

2.Tip seat forward

NOTE: The forward travel adjustment bolt adjusts forward travel of the steering lever. The rear travel adjustment bolt adjusts the rearward travel of the steering lever.

3.Adjust speed by:

•Turning adjustment bolt clockwise to decrease steering lever travel.

•Turning adjustment bolt counterclockwise to increase steering lever travel.
