How to Adjust a Belt Tensioner on a Toro Walk-Behind

Save

Toro walk-behind mowers use a rubber drive belt to propel the wheels. The mower has a tensioner adjustment mechanism to ensure the belt remains tight on the drive wheel and pulley assembly. A loose belt will not propel the mower effectively and may wear out prematurely from slipping on the metal drive wheel. Adjusting tension on the belt takes only a few minutes.

Things You'll Need

  • Screwdriver set
  • Shut off the Toro and wait for the engine to cool. Pull the spark plug wire off the tip of the plug on the engine block.

  • Take out the screws holding the belt guard cover over the drive mechanism. Remove the cover to expose the drive belt and tensioner.

  • Loosen the four handle bracket mounting screws on the tensioner. There are two screws on each side of the bracket surrounding the drive belt.

  • Loosen the screw on each side of the rear height adjuster bracket.

  • Slide both ends of the tensioner mechanism until the belt is taut on the pulley wheels.

  • Tighten all bracket screws with the screwdriver.

  • Engage the drive lever on the Toro. When pressing the center of the belt with your thumb, the belt should give less than 1/2 inch with proper tension.

  • Replace the belt guard cover and secure with the screws.

  • Attach the spark plug wire to the plug tip.
