There’s a lot of those upgrades to do to make the thrower/blower turn fast to put the snow out farther, but, ya gotta have the hp to do that, or as you get into the heavy stuff the engine will slow down and your throwing distance will shorten. Just think of a car with a V8, and 3.08 differential gears. Change the gearing to 4:10. The difference is amazing. Power thru all gears, the 3:08 car will be sluggish thru the gears. The 3:08 car will go faster, but when it hits a steep hill in high gear, it will drop speed. The 4:10 car May slow a little on steep hills, but will keep the revs up and be going, with out down shifting. Same thing with a snow blower or thrower. I know, I slowed the speed down in my Ford blower and it worked much better. Still thru the snow good. Not much different. And did have to slow down and let the engine speed back up, before the gearing change. Stop and go, stop and go, with the reduction in blower speed, I could keep a steady speed pace.
Just my experience. Yours will be different.
