Balanced relationship. :p
I thought it was probably photoshopped, but the shadow is right, and more importantly so is the front wheel and axle. The front axle is set up on a central pivot with some movement and you can clearly see the remaining wheel is canted over and the axle is not on the level. Unlike their relationship.:D Where do you guys find this stuff? :?

Well put Cliff! :U :U :UQuote:

BTW, if the back wheels were water filled (which is what we used to do with our tractors) it would be pretty close to balanced even without a big fat mama on the back. Our tractors used to wheelstand pretty easily even with steel weights on the front wheels, under the nose and a 200 litre water drum hanging off a bullbar on the front (handy for pushing the guinea grass under the motor and away from the radiator).

looks real to me , blow up the picture and put a rule on your screen from the top of the front wheel to the end of the shadow then keeping the same angle check the top of her ( at least I think it's a her ) head to the end of the shadow and they match :D

I stand corrected. I thought it was a shadow of his head, but ray-tracing proves otherwise. I'd forgotten about filling the tires with water. We used to use salt water for colder climates.
Joe
We ran old British tractors (Nuffields) and they had adjustable shutters for the grill and recomended a calcium chloride solution in the tyres (from memory) to prevent freezing. Needless to say, working in the tropics the shutters had been removed many years prior and we never had to put anything other than water in the tyres.Quote:

I hate to bust your bubble, but water in the tires won't act as a counterweight. Think about it, to act as a counterweight the weight must be on the OTHER side of the pivot point.
Back in the olden days water was used to add weight to the rear end, this was to aid traction, in these modern days they use radial tires, and lower inflation pressures to limit compaction. I dunno what ideas they will have tomorrow.
Counterweights on the front are used much more these days than in the past, particularly in FWA tractors with radials. Ya don't want a tractor trying to throw its nose in the air do ya. :o
Outback,
in this particular case the tractor would be pivoting from a line drawn through the left rear wheel to the front right wheel, thus the right rear wheel would act as a couterweight (as would the large lady sitting above it):q
Mick
I didn't want to buy into this one but gee just can't help myself. Anyway the shadow looks OK to me but not so much that I can guarantee anything. Anyway others who have fancy letters after their names have worked that all out.
Regarding the counterweighting by filling the tires with water, that would act as a counterweight. If you increase the mass of the wheel and tire by filling it with water you increase the mass at the rear of the tractor and so the centre of gravity moves towards the rear of the tractor. In fact depending on the tractor's centre of gravity you could put a mass infront of the rear wheel and it might be possible to move the centre of gravity towards the rear which is all that a counterweight does.
Now of course if it had a load on the fork lift at the back that would have even more effect but doesn't change the fact that you have been able to move the centre of gravity.
Growing up in the country I don't remember anyone putting water in their tyres but that was the Riverland which is generally flat and dry too. Plenty of people had counterweights fixed infront of the radiator because they used to have fork lifts on the back to lift bins of fruit onto trucks. It was easy to pick tractor up and still have your fruit bin on the ground!

OK, so once again I know nothing. I am glad this palce is full of experts in everything.
Actually, the ones I was talking about were rubber-tired four-wheel cranes with the pivot at the center of everything. For those, they really do provide some counterweight, in addition to the one on the boom, by increasing the mass of the lower works.
Joe
Don't worry about it fellas it is real, I have done the same thing without my wife standing on the back.
We put water in the tires to increase the weight on the ground thus increasing traction and stability.
But tell the city folk it so we know when there is a puncture
