Although somewhat confusing to an Old Phart this is an interesting topic. I'm beginning through every posters input see the light at the end of the tunnel. One last thought wouldn't the back 1/2 any weight on/in rear wheels contribute to the same counterbalance weight as on the 3 pt IE approximately 45% of the weight(wheel weights) in question would be behind rear axle??????????
Yes it is behind the rear axle, but it still won't do any good in the sense of "prying up" the front of the tractor as it is not attached to the chassis of the tractor to act as a lever arm to act around the fulcrum of the rear axle. Let's put 10,000 lbs of wheel weights on the right rear wheel. since they are round and balanced, you would have half of it forward of the center of the axle and half behind the rear axle. They would balance each other out, and you would have 10,000 lbs pressing straight down thru the tire to the ground. BUT it would not matter if you removed the 5000 lbs that was in front of the rear axle and still had the 5000 lbs that was behind the rear axle it still would not "pry up" the front of the tractor one little bit, what it would do is try to rotate the wheel/tire backwards as it is now unbalanced and would try to rotate until the weight was balanced at the lowest point. Do not get us wrong, putting on wheel weights or loading fluid into tires will help prevent the rear of the tractor from raising in the air when you put too large of a load in the loader bucket, but in no way will it take weight off of the front axle. You must have a prybar and a fulcrum point of the rear axle to do that. Here lets make a boompole on the 3pt that is 100 foot long. Now that is quite a "prybar" right? now lets put 50 lbs on the end of the boompole. What will happen. Likely the front of the tractor will lift in the air right? Maybe even the 100 foot boompole itself would have been enough to lift it in the air,depending on what it was made of and what it weighed per foot. I hope these absurd examples are helping not hurting.
