I am planning on using the tractor to dig out for a garage and a couple small ag sheds, dig a 3'x3'x400' ditch, install 80' of 24" pipe, 500 ft of water line, set 200- 6" posts, install 4000' of fence, cut and bale 5 acres for hay, keep 5 acres clear, seed and fertilize, keep up 1300' of gravel drive, and perform normal maintenance on a small farm.What are you asking the tractor to do? I'm curious what you are going to do to stress the tractor.
For hills the rear wheels need spaced out as far as possible. Also fluid in rear tires will give tractor lowest center of gravity... fill 3/4 up.
