Tractor Stability on Hills

[CobyRupert]

If you think of the downhill tire as the fulcrum (pivot point) , it's only when the c.o.g. rotates beyond an imaginary line straight up/ plum from the fulcrum that the tractor tips over. (Simplified).

Figure 5. The tractor on the left is operating on a level surface. The tractor on the right is traversing a hillside much like the tractor was in this incident. When transporting an elevated front-end load on level ground there is no C.G. shift to the side and the C.G. remains within safe limits. When transporting an elevated front-end load while traversing a hill, the C.G. is more prone to leave the safe limits of the tractor's stability baseline. Once this happens the tractor begins to roll. The higher and heavier the load, the less the land needs to be sloped for a rollover to occur.

Nice illustration, bcp. If the cog is below the axle, the roll over point is way way beyond anybody's pucker point.

I would prefer a more narrow four point than a wide three pointer I think.

That definitely drives the point home.

Just a JD box blade and Kubota tractor wrestling it out for brand superiority... Nice body slam! unch: (happy everyone in that incident was safe)

Safety can never be assumed even on a hill you've travelled a hundred times. Preparation and caution should remain continuous.
