Motorcycles with considerably more power use chain or belt drives.(clip)

However, remember that a motorcycle develops full power at around 100 mph,
while a snow blower goes, maybe, 3-4 mph. If you really need 50 HP at that
low speed, the chain tension will be about 25 to 30 times as high. However,
I am not clear on the concept. Isn't most of the power going to be used to
throw the snow? How much will actually be used to drive the wheels, and how
are you planning to divide it?
