The JD 4 wheel steer lawn tractor I had to use at the ranch i worked at a long time ago in E-Burg sucked. Sorry, not worth it. Just get a snowblower. The walk behind ones work pretty good.
The Lawn tractor could only push really light snow off the sidewalks around the car barn. Little bit of ice, little bit of wet....no-go...
At the ranch I had....ehh, I think it was a 4235? small diesel and a big Massey loader 4x4 to move the snow on the paved driveways. The lawn tractor blade didn't work at all. But, then again, I had a lot of snow to move and it was in Thorp.
