Troubleshooting, Adjustments, & Service

NEUTRAL ADJUSTMENTS

If the machine creeps while the motion control levers are locked into their neutral locked positions, then it may be necessary to adjust the link rods.

Perform this adjustment on a hard level surface such as a concrete floor.

IMPORTANT NOTE: This adjustment should be per- formed with the engine OFF. Perform the adjustment, then start the engine to check the adjustment. If further adjustment is required, stop the engine before perform- ing the adjustment.

1.Determine which wheel is creeping. The left side transmission and link rod control the left wheel, the right link rod controls the right wheel.

2.Disengage the PTO, lock the motion control levers into their neutral locked positions, turn the engine off, remove the key, and wait for all moving parts to stop.

3.Remove the hardware (C, Figure 23) connecting the rod end (B) to the control bracket weldment (A).

Note: The rod end is located under the fender beside the operator seat.

4.Loosen the rod end jam nut (B).

If the transmission is creeping forward, turn the rod end in (clockwise) one or two turns to shorten the link rod (E).

If the transmission is creeping in reverse, turn the rod end out (counterclockwise) one to two turns to length- en the link rod.

5.Retighten the jam nut, and reconnect the rod end to the control bracket weldment.

6.Start the unit and check for transmission creep. Repeat steps 2-5 if necessary.

7.Once the correct adjustment is achieved, check adjustment of the compression spring (F). With the motion control levers in their neutral locked positions, the spring should have no compression, and should have approximately 1/16-1/8” of free play between the washers at either end. Turn the two adjustment nuts

(G) in or out until the desired adjustment is achieved.

WARNING

Incorrect adjustment of the compression springs can cause motion control levers to move from neutral into forward or reverse. This can cause unexpected machine movement, and may result in possible injury and/or equipment damage.
