  Kimberly SullivanAug 29, 2025
  If your Husqvarna Snow Blower is experiencing loss of traction drive or a slowing of snow discharge, it could be due to several reasons. The belt might be slipping, worn, or off the pulley – in such cases, try adjusting or replacing the belt, and adjust the pulley if necessary. Also, check if the chute deflector is clogged and clean it. Remove any foreign objects from the augers. If the shear pin is broken, replace it. Finally, clear any excessive snow and ice buildup in between continuous track components.
