Toro Electric Snowblower Repair

Toro (boo!) discontinued key parts for their old electric snowblowers. With a bit of effort I was only able to replace the bearing in the pulley and get the unit working again. We look forward to more years of snow removal! Thank you to another reviewer who did the same and gave me the confidence to keep going. PS - since I don't have an alternative, I added a few drops of mineral oil for lubrication.
