We have an Erskine pull type snowblower on the farm in North Dakota since 1975 or so. It was a good investment especially because it didnt snow for a few years after Dad bought it. It has a wing extension on one side. I would not have one without that. It has seen some rough use through the years, on gravel road and around feedlot, origionally had problems with the shaft slipping in the bearings (moving forward or backwards. Had to reinforce the hanger bearing mount, reinforce the impeller, wing mount replace cutting edges. It is a good style of snowblower for long roads and runways as you have alot more gears foreward than reverse and dont have to back up
