I will have to disagree on this.
Dad had a Massey Ferguson Industrial 35 (50HP Perkins diesel, industrial loader with a 6' bucket, chains on the (loaded) tires, a beast of a machine). When clearing snow with that machine, you ran out of traction quick, even with a 55 gallon drum full of rocks in the 3 point.
He replaced that with a Kubota
L3650. Smaller tractor, but has 4wd and 4 loaded tires. That tractor does a MUCH better job at loader work WITHOUT any extra weight on the back and in the snow, it will push and push. It doesn't stop for anything until you tell it to.
It also has a Laurin cab with heat which makes it MUCH more fun to work in during the winter.
