I have a 2182 with a 451 blower. I dont want to open a can of worms but I always snowblow WOT. the snow is thrown 20 feet or more. I move about 1/4 to 1/2 speed - keeping the blower full with ground speed works best by my experience. I have foam filled tires, 150 pounds of wheel weights, chains, a full steel sims cab and my 250 pounds in the seat. - the snowblower is heavy I highly suggest counterweight of some kind. if I drop the blower completely on the pavement I lose all steering wheel turning ability. My drive is gravel if I am not careful I put lots of gravel on the first floor roof of the house and hit second story windows with stones and snow.
