SERVICE AND MAINTENANCE
Drive Control Lever Stop Adjustment
When the drive control levers are both fully extended forward to the full-speed
position and the tractor drifts left or right, the drive control lever stop adjustment
can be adjusted to sync the wheel speeds. To perform the adjustment, proceed as
follows:
1.
Identify the side that the tractor is drifting to and adjust the opposite drive
control lever. If the tractor drifts right, adjust the left control lever down
(decrease speed) and vice versa.
2.
Locate the drive control lever stop adjustment bolts on the front of the seat
frame. See Figure 23.
Figure 23
3.
To decrease the forward speed, turn the bolt clockwise. To increase the
forward speed, turn the bolt counter-clockwise. Turn the bolt in the
necessary direction
1⁄4
-turn at a time. After turning the bolt, check the
adjustment by driving the tractor.
4.
Continue the adjustment until the wheel speeds are in sync and the tractor
drives straight with the drive control levers fully extended forward in the
full-speed position.
Deck Removal
Remove the mower deck from the tractor as follows:
1.
Move the tractor to a level surface, disengage the PTO, stop the engine, and
set the parking brake.
2.
Move the deck gauge wheels to their highest setting (lowest deck setting).
3.
Remove the ‘V’ belt from the PTO pulley, located on the bottom of the
engine, using one of the following two methods.
WARNING
The muffler at the rear of the tractor may be extremely hot, and could
cause serious burns. Use extreme caution when near the muffler. Allow the
muffler to fully cool before removing the belt from the PTO pulley.
4.
Releasing Belt Tension with the Idler Pulley
a. Using the deck lift handle, raise the deck to the position that provides
the most horizontal run of the belt between the deck idler pulleys and
the PTO pulley on the bottom of the engine. See Figure 24.
