not much snow about 3" but it was wet, i was thinking of adding more weight to the the drum so it doesnt slow down when it hits heavier snow. An extra 100lbs of rotational kinectic energy should help. Also the design of the flight at the center of the drum could use some tweeking. If all else fails i have a plow truck but its hard on the 3/4 clear driveway
With the single stage and heavy snow it's going to be hard to get it to hurl it a long distance. Have you tried it with lighter snow to see how it works. As far as adding weight to the auger, that would give you some flywheel effect but would have to be balanced perfectly and would likely burn the belt on startup as you have to add the kinetic energy when you accelerate the mass. It would also only help for a short time and when blowing snow of a constant depth there wouldn't be any advantage. When lifting the blower the increased weight might be a problem as well.
I havent really tried it in light snow but id like it to work in any conditions. Balance is no big deal i have two dynamic balance stands at the shop and i agree for sustained use the extra weight wouldn't be a fix but my yard drifts bad. I was sitting at the bench last night and had a crazy idea to replace my v-belt drives with posi-drive belts, i have a couple pneumatic clutchs from jack shafts that could make it all work. Im also thinking of repowering the old girl but id realy like to keep the original engine; it just doesnt pack much punch. I have a 16hp v-twin vangard that would really wake her up and i think i could make it fit if i ditched the stock air cleaner and moved the battery but it just feels wrong to do that to a stock tractor in such good shape lol
Check for belt slippage and proper pulley size. Speed is critical and to fast is as bad as slow. We have one and it does a good job of moving snow. As stated above wet snow is not going the going to far from a single stage blower and they do consume more power than a 2 stage blower.
