We finally had enough snow worth pushing (6" of heavy wet snow) the 500 did very well !!
I had two, 75# suit case weights in the back and I weigh roughly 140#.my driveway goes up hill at the bottom (about 20 degree incline) and it pushed up hill, in 3 wheel drive,with no problem at all !!
I have a 23 hp diesel tractor that has 4 wheel drive and it always had traction problems, pushing or pulling snow and the pioneer easily out preformed the tractor.
The only complaint I have about using this machine for plowing, would be the shifting,a shift lever would be much easier ,but I can adjust to this (not a big deal)!!............love this thing !!
