CVT Drive and brake system

Tensioner pulley control rod
The tensioner pulley control rod is the link that ties the
pedal shaft to the pulleys that tighten the front drive
belt. See Figure 6.16.
If the tensioner pulley control rod is out of adjustment:
• Gear engagement may be crunchy (if the clutch/
brake is not set) because the front drive belt ten-
sion is not fully released. Link too short.
• The tractor may creep when it is in gear, even
though the operator’s foot is not on the drive
control pedal. Link too short.
• The tractor may not have it’s full range of ground
speeds. Link too long.
The tensioner pulley control rod may also need to be
adjusted after the drive belts are replaced.
