How to Change Belts on an MTD Snowblower

Your MTD snow blower has one belt that you'll never probably think about until the moment it fails, and you're left watching the snow stack up on your driveway. When your unit seems to be running yet it isn't propelling itself forward, you'll need to replace the drive belt. Over time, the snow blower belt can develop dry rot, causing it to fray or snap. Fortunately, changing the belt yourself should take no more than 10 minutes or cost more than $20, saving you an expensive trip to the shop.
