6. Release the cable from the transmission housing by
squeezing the barbs that lock the cable housing into the
bracket on the transmission. See Figure 3.22.
7. Route the cable out of the frame.
8. If the snow thrower has the three speed drive system;
• The ground speed is controlled by the speed selector lever
located on the left side on the upper handle bars.
• In order to change the ground speed the engine needs to be
running and the drive engagement must be released.
• The speed is controlled by a variable-speed pulley system
located in front of the engine.
• Removing the clutch cable of a three speed snow thrower is not
much different than removing the transmission from a single
speed snow thrower.
9. Reinstall the cable in reverse order.
10. Test-run the snow thrower before returning it to service.
