Hey Bill Bruce already mentioned my Snowpig above and it's in the evalbum - http://www.evalbum.com/4544. I built it for probably the worst winter snow clearing conditions, very wet heavy snow on a dirt road that has hills and little traction. Lots of learning experience! I found that most blower mounted tractors use a really long belt or a PTO assembly that sucks lots of horsepower. My MARS ME1003 is mounted close with a much shorter belt so the power loss is much less. Typically you can go controller less as the speed is usually close to fixed in snowblowers, just match your desired speed with pulley size. Under no load it consumes very little energy as the auger spins freely. As the snow starts hitting the auger the amps will go up. A belt is good to have as it acts like a fuse when a rock jams in the auger. I haven't had any problems with the blower motor, it works really well and barely gets warm to the touch. The motor that moves that cart I had lots of problems with last year, likely to do with how golf cart motors aren't really designed for continuous heavy duty like we had with the snow last year. Then again other roads close to me had to bring in excavators to move the 5-6ft snow drifts, it was a crazy winter last year! I already have an ammeter and digital thermometer installed in the cart for this year. As for range, more batteries are better, the weight also keeps the pressure on the drive wheels and will likely keep your snow blower from dancing around as you guide it through snow banks. I have used lots of snowblowers in the past and I find the older ones tend to be better in this area just because they weight more.
Feel free to PM me if you have any questions!
