I've been into Snowblowers and Repairs for the last few Years, Specializing, but not limited to Old School Ariens Machines. Last Week I did a friction wheel on a newer Ariens. I couldn't Believe this Had a PLASTIC GEAR to drive the Wheels! The Founder of Ariens would Spin in His Grave if He saw the Quality of this! Built-to-Fail vs Built-to-Last.
