I don't really understand. We have had some heavy snows this year, and I've been pretty impressed. You can't expect a machine to pull itself when its belly is lifting its weight off the tires from dragging in deep snow.
I will agree it feels squirrely in snow. I believe this is mainly due to the locked rear, I had a jeep that was locked front/rear, and it was awful to drive in snow. However, it would go like ****, just perhaps not the direction you pointed it
I drove some county roads that were heavily drifted/closed in the pioneer, and then later in a 4wd truck. The truck has more ground clearance, and felt very similar in its limits as to where it could go compared to the Honda. I tried to pass through a section of closed road in the Honda, and got hung up. It took me 10 minutes or so to get backed out, mainly due to the reverse limiter preventing much tirespin. A neighbor had come down in a tractor thinking I would need pulled out, he reached me as I finished turning around in the road. The first thing he said was he was surprised at how well it did in the snow. (He has a Kubota rtv)
In short- it goes like **** in snow IMO. I would be shocked to see a UTV with the same ground clearance and similar tires go any better in deep snow.
This is its "limits". I backed out of this, and even turned around (30 point turn!) in the drift in the road. I don't see how you could expect any better? Perhaps tracks are in your future?
