I run a 70 hp JD 3020 with differential lock. 800 lbs wheel weight, Westendorf 7 ft. Loader and 7 ft. Snowblower. Does fine on snow and minor hills. If it’s icy you can add chains.Also use a 40 hp skidder with 7 ft. bucket and four wheel chains and it is a beast at pushing snow. Also have a grapple bucket for it which is my wood mover. Has aux hydraulics for the wood splitter but I prefer the 3020 for the splitter As it has auto return. Without differential lock they can get a bit helpless with some terrain and conditions, ie. packed snow, ice, mud, etc.
