How to replace a snowblower auger belt
This DIY repair guide shows how to replace a snowblower auger belt. Replace the auger belt if the snowblower won’t throw snow because the belt broke and won’t spin the auger. Also replace it if the auger drive belt is so worn that it slips or squeals when you use the snowblower. Use the manufacturer-approved snowblower part to replace the auger belt.
This basic repair procedure works for many Craftsman, MTD, Murray, Husqvarna, Toro, Snapper, Troybilt, Ariens and Noma snowblowers.
