In another post, I mentioned running my tractor on these hills here in WV and being nervous. On a whim, I went out yesterday, and measured the slope in one of the steeper parts of a field. Right around 19%. The tractor manufacturer does not recommend anything greater than 15%. Even the tractor forums say nothing 20% or over. So now I'm resetting my tractor rims. By flipping the inner dish and moving the outer rim to a different position. I should be able to widen the footprint by over a foot on each tire. This should greatly reduce the rollover potential. If that is not enough, I will add liquid ballast inside the tire to further lower the center of mass.
I remember mounting those tires many years ago. Now my girl muscles are having trouble just rolling the tires around, much less trying to pick one up when it falls over. Taking the lug nuts off is another matter. I have a 3/4 in drive breaker bar with a 4 foot pipe slid over that and I'm just getting enough leverage to break them free.
When I bought this place it came with a Steiner 450 tractor/mower. This in an 4x4, articulating beast. The previous owner had the dual tires added all round and weights. I am getting used to it and have determined it is impossible to flip. It only slides sideways if the hill is to steep. Staying in the seat is another matter, though.
Work on the house is progressing. Sub floor is now complete. Added a few beams and removed some load bearing walls. The rest of the tongue and groove ceiling has come down. What a messy job that turned out to be. Now its just build a house inside that shell! Easy, peasy, haha.
