Here’s a good complete auger shaft /impeller assembly that came off a 1973 Ariens Sno Thro 420 snowblower. This assembly fits many other similar era Ariens 420 models too, so please check your applications pic. This unit still worked well on the blower. The axle still shows a decent shaft devoid of deep, brutal rust–just some light spider webbing or staining.. The scooped snow was thrown well by the impeller which shows normal edge contact wear. The paint shows normal wear and pitting common to these. The metal fan blades show very nice without contact bends, brutal rust, or a bent backing plate. The backing plate is one of the best you’ll ever see off a used blower of this age! It’s also nice to be able to slide the rakes off for servicing easily. Better yet, if you need to clean and lube the hubs–they will slide off easily–especially with a with a clean lubed axle! The rear shaft keyway looks good. The transaxle end shaft play shows normal run-out and is completely usable. Great unit for a spare as well. The seals are good with some light weeping typical of the age of this system. These are getting difficult to find in working condition. You are getting everything you see in the pictures. The ol’ Ariens 420 sno-Thro’s were among the toughest small blowers ever made. They are still top performers today! Please thoroughly clean and lube prior to use. Look for more good 420 snowblower parts in my other auctions. Please look at the pictures. Ask any questions that you might have.
