Working in the woods-steep slopes: you have to be careful here. It's unfortunately the case that you can roll a tractor pretty easily on what appear to be gentle slopes if, for example, you're mowing along the slope and your down-slope front wheel drops into a hole that you don't expect or see. There's no substitute for wide stance and low center of gravity if you intend to use your tractor on slopes.
I've shown these photos many times on TBN the last 5 years--namely, my modified 1964 MF135 diesel that's set up to squat low with oversize rear wheels to maximize the stance. People are probably tired of seeing them, but if it helps, I'm OK with it.


It's a field tractor modified to squat low and have high flotation for work in the olive orchards around here (trees planted on 20-25 ft grid). The normal 28" dia rear rims have been replaced by 16" dia rims that carry those wide Goodrich 6 ply 18.4-16A tires. The front axle spindles are short to keep the tractor level. The axle height is 20" to the axle centerline and the stance is 83" measured to the outside wall of the rear tires. This gives a squat ratio of 4.15. Typical field tractors with taller rear wheels have squat ratio around 2.8-3.0.
The 135 mods are one way to make a tractor safer for work on slopes. Another way is rear duallies.
Take care and be safe. Good luck on your tractor quest.
