I am using these skid shoes on another brand snowthrower that is no longer in business (Maxim). These shoes exceeded my expectations for heavy duty and easy to install.
I bought these shoes for my commercial grade 1332DDE John Deere snowblower which was actually made by Ariens as nearly all John Deere Snowblowers were in the early 2000's. The 1-sided John Deere version of these commercial heavy duty shoes were $60 for a pair. I received these double-sided commercial heavy duty shoes at a cost of $45 for a pair. Tough to beat that price for a 2-sided heavy duty shoe that will last virtually forever for residential use.
