Auto-Drive CVT Drive System
49
Linkage: Cobra head to control rod tie plate and hex bushing
NOTE: If there is reason to replace the tie plate and hex bushing, it can be replaced without disassembly of
the pedal shafts. The most likely reason for this would be the discovery of damage to the tie plate or
hex bushing while making an adjustment to the tensioner pulley control rod.
1. Remove the mowing deck.
2. Remove and discard the cotter pin that holds the ten-
sioner pulley control rod and the tie plate to the
“cobra-head” arm on the drive control pedal shaft.
See Figure 5.29.
3. Slip the tie plate off of the “cobra-head” arm, and
pivot it downward.
See Figure 5.30.
4. Slip the tie plate off of the hex bushing, and remove
it.
5. Snap the hex bushing off of the brake pedal shaft.
NOTE: The hook on the tie strap goes over the trimmed
section of the flange on the hex bushing.
6. Install the tie strap by reversing the process used to
remove it. Use a new cotter pin to secure the idler
control rod to the cobra head.
7. Test-drive the tractor to confirm that the drive system
is working correctly before returning it to service.
