have you heard of this...
A guy on another forum had this to say about his Gravely Convertible snowblower.
"...Gravely Convertible, 12 HP Kohler cast iron engine, 26" width, 2 speed impeller with 4 ground speeds, chains, weighed 600 lbs. All gear driven, no belts, the internal gearing was such you could get speed or power. With the weight and chains, this was not going anywhere. It was non stoppable, neither the movement forward nor the auger and impeller. It blew the snow across a four lane road and hit the buildings if I wanted..."
Pretty impressive! I can see the GAS.
