I have decided to go with a set of Pat's easy hitch hooks. The LS J2030H that is now happily on the way in the next couple weeks has a lift capacity of 1433 LBS at the ball ends. Now it's not a question of rather or not I will go with the Pat's, that's been decided. The question is, how much capacity do you lose for every inch further out from the ball ends you go? My assumption is that it's not a heck of a lot. We are talking 3 to 4 Inches that the Pat's add to the length of the arms. Obviously you have to reduce the amount of weight you attempt to lift the further out from the ball ends you get. But I have been told that I can easily pick 500 LBS with a boom pole, and that is considerably further away from the ball ends on the draft arms. Yet in all the threads that I have read, this 3 - 4 inch of extension keeps coming up as a concern/negative. And yes, I have already figured in the extra length needed for the top link and the PTO shafts. (That's the beauty of buying new stuff)

I do not have a boom pole, and the heaviest bit of equipment I will be getting with the tractor is prob the tiller, or maybe the brush hog. So for the sake of argument, lets say the the tiller is 300 lbs. most of that weight is not centered on the ball ends, its effectively some distance behind them, which means, (If I am thinking correctly), that the required force to lift the tiller is something more then 300 lbs. Or should I say, the force at the ball ends is more then 300 lbs. Moving the hitch pins an additional 3 - 4 inches out would have the effect of amplifying this. The question is, what kind of amplification are we talking about? Is it a linear scale, such that each Inch you move out, the weight is increased by a fixed amount, or is is a non linear scale, such that each Inch you move out, the weight is increased by an amount greater then the previous inch increase.

The problem is, I don't know how much force my 300 LB tiller actually requires from my 3 point hitch in stock configuration. Nor do I properly understand how much of an increase in force will be required from the 3 Pt by moving th weight out 1, 2, 3, 4 inches further.

The fact that it keeps coming up as a concern in threads about the Pat's indicates that the increase is substantial. But is this just a matter of over estimation, or is the increase really that substantial? Does anyone know how to calculate this?
