Many ice anglers are switching to 4-cycle propane powered augers because they are clean burning and low maintenance. Instead of just adapting a gasoline engine to run on propane, the engineers at Eskimo designed the engine on the HC40 to take full advantage of the high octane rating of propane fuel. The higher the compression ratio creates more power out of a smaller package, which means the anglers has a lighter weight auger with the power to cut either an 8 or 10 inch hole. The Eskimo high compression propane auger gives the ice angler the reliability and dependability they have come to expect from Eskimo in an extremely powerful, lightweight package.
