How to Adjust a Toro's Auger Belt

Toro snowblowers have a helical blade, known as an auger, that scoops up the snow and throws it to either side of the machine. In Toro snowblowers, the auger is driven by a motorized belt and pulley system. If the tension of the auger belt is too loose or too tight, the auger won't perform as expected. You can correct a slipping snowblower auger by adjusting the belt tension. The process is so simple that you can complete the auger belt adjustment in less than 10 minutes.

Step 1

Locate the thin hex nut, known as a jam nut, on the clevis at the bottom of the auger drive control rod. Loosen the jam nut, using a jam nut wrench.

Step 2

Remove the cotter pin and clevis pin that hold the clevis to the bent rod. Reserve the removed pins. The cotter and clevis pins are small; be careful to avoid losing them.

Step 3

Rotate the clevis to adjust the auger belt tension. Turn the clevis counterclockwise to increase the belt tension or clockwise to decrease the tension.

Step 4

Replace the removed cotter and clevis pins to hold the belt at the desired tension. Tighten the jam nut to lock it against the clevis.
