You are gonna have to "splain" that one to me!

Regarding the effect of a counterweight on the 3 point hitch is well demonstrated with scales under the front and rear wheels in the Messick’s YouTube linked in post #3. You may have a valid question regarding my conclusion of the effect of increasing weight in/on the rear wheels. My belief is that in a static situation likely all weight below the rear axel does not increase load on either the front or rear axles, whereas rear wheel weight above the axel will increase load on the rear axel and likely have a small amount transferred to the front axel; similar to you sitting in driver's seat, where the majority of your weight would be borne by the rear axel, but some would be transferred to front axel. I can't see how weight directly on the rear axel would act as a fulcrum and unweight the front axel, but if you hang it off the rear of the tractor it does shift weight from the front to the rear axel. In a dynamic situation the movement of the liquid weight in the rear wheels may or may not change the weight distribution. I received a C and a B, respectively in 2 semesters of college physics and those grades were a gift because of the class curve so my conclusions may be wrong. Certainly welcome other thoughts.

That's a nice explanation.

Found a good link on TBN regarding weight distribution under different loads.
It appears rear wheel weight has no appreciable impact on front axel load, neither lighter nor heavier.
This seems logical to me. If I divide the rear tire into 4 quadrants with a vertical and horizontal line that transect the wheel's axel the 2 quadrants below the axel have minimal impact on the rear or front axel load, but the upper 2 quadrants would load the rear axel. When looking at a side view of wheel the forward upper quadrant will ever so slightly increase front axel load, but the rear upper quadrant would totally counterbalance that load, hence no net effect on the front axel.

WEEEEEEW, and I was just about to go out and drill big holes in the rear tires on my loader tractor, just to take the weight off the front axle!!

And i got up and turned on my computer because I couldn't sleep. Think I can now; g'night again.
