Can not confirm on that tractor, but did have a B2320 HSD with a 5' back blade. It worked OK in light snow, but would push the rear end sideways in heavy snow. The B2320 is a little heavier than yours and I had loaded tires on top of that. So as far as a front blade is concerned, the front would be lighter yet and with the blade angled, I would think you would have a tough time not pushing the front sideways in heavy snow. A 48" - 52" blade would cover your tire tracts and may work better. But take that for what it is worth... not comparing apples to apples, but that would be my guess and the reasoning behind it
