Tools Required


13 mm


1/4" drive


7 mm

Needle Nose Pliers

Never store the machine with gasoline in the fuel tank in a confined area with improper ventilation. Gasoline fumes could reach open flames, sparks, cigarettes, etc.

  1. Remove the five belt cover screws with a 7 mm socket. The bolt securing the front belt cover (#1) is the only one with a washer.
  2. Release the cable adjusting nuts with a 13 mm wrench by loosening the inner nut first.
  3. Thread the outer nut all the way down to create maximum slack in the cable.
  4. Remove the cables from the forward and reverse control levers.
  5. Remove the reverse cable end hook from the tensioner arm.
  6. Remove the forward tension cable from the tensioner arm.
  7. Route the new cables and connect their ends to the tensioner arms. The cable with the longest wire (green arrow) exposed is the bottom cable controlling the forward engagement. When reaching through to install the cables, do not rotate the drive wheel or rotate the tines.
  8. Reinstall the forward cable in the left-hand lever and the other in the right-hand lever. Pull the cable adjuster out until slight tension is felt and hand tighten the adjustment nut.
  9. Belt Tension Adjustment
    Loosen the nuts holding the tine engagement cable to the tiller body. Move the cable away from the drive pulley to decrease belt tension, then re-tighten the nuts.
    To Increase Belt Tension: Turn the jam nut clockwise in 1/8" (3 mm) increments. Test the travel distance of the engagement lever again to see if travel before full engagement is less that 5/8" of an inch. If it is still more than 5/8", readjust the cable.
    Note: If there is no more cable adjustment left, the belt has become stretched and will need to be replaced.
