1) There are several people who have made electric snow blower
conversions, check out the evalbum. There are also a few commercial
offerings (e.g. EGO snowblower
http://www.homedepot.com/p/EGO-21-in-56-Volt-Lithium-ion-Single-Stage-Electric-Snow-Blower-with-2-5-0Ah-Batteries-and-Charger-Included-SNT2102/207099229
)
2) Buy the cheapest motor/controller you can find. Probably a brushed DC
motor with simple PWM controller if buying new, but on the used/surplus
market you may get something trickier. You can probably aim for a 7HP /
5,000 watt motor instead of a 10 HP motor, as the electric motor should
have more torque.
3/4) Wait for people who have done it to chime in.

From your description of snow/current unit, I'm assuming the EGO unit
(21") may not be large enough for you, or if it is, you may need to buy
2x or 3x the number of batteries to get enough runtime. But do keep in
mind that the commercial offering starts at $600, so that's your lower
budget number. Unless you are sourcing used/surplus motors and have a
free battery supplier, I think it will be hard for you to do this
project for under $1,000.

We get lots of snow where I live. I'm often clearing a foot or more of snow
using a 10.5 hp, 30-inch wide, 24-inch tall unit. I've recently been offered a
similar unit with a blown engine, and I'm toying with the idea of trying to
make it electric. It seems that battery electric snowblowers on the market
only go up to 21-inch width and low horsepower, so really not big enough for my
needs.
So I guess I'm asking a few things:
1) Is this even a feasible project
2) If so, anyone have suggestions on how to proceed (for example,
shunt motor vs. series motor, etc.)
3) Any pitfalls I need to look out for (for example, the gasoline
blower has a governor on the engine--do I need something similar)
4) Anything else I'm not thinking of
Thanks,
Bill
