I was in the same boat you guys are in. I bought my first ATV in 2006 (Jan) and sold it the day my Pioneer arrived. I looked at all of the UTV's and compared options and prices. I really need one to work, first. Playing isn't why I'm spending $13K+ of my money.
I don't plow a lot, but I do plow "some". Our most recent snow saw me plow 11 neighbors drives (some short and some long). I have wonderful neighbors who allow me to hunt their land. In return (not by contract....just a gesture), I plow their drives. I never once have had to even put my ATV in 4WD to plow any of them. Mine is the worst. Even with slick tires, the ATV handled this last snow like it wasn't even there. I put my KFI plow together, yesterday. It's a 6' model (ATV plow was 54", I believe). It's quite impressive in size and weight.
We're supposed to get some snow this week. I'll give you an honest assessment of how the Pioneer does, if we get it (the weather). I'm no fanboy of the Pioneer. I AM a huge fan of their engines (I have Honda engines on two other pieces of equipment I own). I'm running the factory tires and wheels (FYI). I'll be actuating the plow with a KFI 3500# winch.
If it doesn't do the job, I'll be HIGHLY surprised. For reference, my driveway is 500' long and on a pretty good grade. Still, the 376cc Suzuki Eiger I owned did it in 2wd (even going up).
Photo is of my drive BEFORE I bought the plow....lol.
