Lift capacity of 3-pt hitch question (plz keep it simple)

[Egon]

Thats because it isnt simple.

We have already established that TL geometry changes things. And the toplink within its range of travel is also infinity variable in lenght.

And different models are different. And there are thousands of tractor models. My tractor is good for 2k at the ball ends. A different model tractor also rated for 2k at the ball ends may have different results further back, cause it may have different configurations for toplink.[/QUOTE

Where has that top link theory been established. Vector diagrams??

Its not a theory.

If you use the lower TL hole it causes the implement to raise more than the top hole with the same given movement of the hitch.

Cant get something for nothing. Raising it higher requires more effort.

IF you have a 500# block on the end of a boom pole, and raising the hitch 10" causes it to lift 30", that requires more force from the hydraulics than if the same 10" of hitch travel only caused the weight to move 20".

And changing how high it lifts in relationship to the hitch (hydraulics) is a function of the toplink.

Someone just answer the question!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Still wondering if anyone can post ACTUAL data before the engineers muddy up the thread any further.

A valid point was made that if you can configure the top-link or choose bottom holes to make the pallet "travel up as level as possible" then your numbers will be more usable.

Put a 3-point pallet lift on and keep adding weight until can't lift it. Post tractor model and the mfrs specs and the weight that stalled it.

What question is that?

 

[LLS]

My l3540 is rated at around 2450# @ 24" and I can lift a 2000# pallet of hydromulch about 18" off the ground

 

[LLS]

He wants to know how much a tractor rated at 1500# of lift will lift? Anyone have a tractor close to that that has lifted something to the max and knows what that weight was?

Good LLS! Page 2 and the question is still apparent to some !

How do you know the pallet is 2000lbs? And if that weight's accurate, can you find 450 lbs to add to the pallet? Couple of good ole boys?

Reason I asked for 1500 lbs is (in general) a 35 HP tractors can probably lift anything it needs to. Under 30hp is where there's more of a need to know what the ratings mean with regards to 3-pt pallet forks. How about put the forks on the 2320 and lift a few good ole boys (who don't lie about their weight like wimmin' :laughing: )?

That is what I am trying to explain. It all depends on how it is set up. Without knowing measurements of the particular model, and how it is set up....how the **** can we know?

Might be 900# if using the lower TL mounting hole. Might be 1300# if using the top hole. Just dont know. But can gaurentee it will be more with the top hole and less with the bottom. How much more or less depends on how far the holes are spaced and the overall geometry of the hitch. A different model (also with a 1500# lift spec) might have totally different numbers.

I already explained a VERY simple way to figure out how much it can lift, and all that is needed is a tape measure, a calculator, and 5 minutes. Find out how much the center of the pallet moves in relationship to the hitch. Then its a simple ratio (or percentage) of the lift spec is what you can lift. Change the toplink and you change that ratio.

What are you trying to accomplish here. There is no simple answer, to your question. Tractors are different. Setups are different. AND setups are adjustable. There is no way to make a blanket generalization as to lift capacity. IF I did (or anyone does) they are lying to you.

I can tell you that ~75% @24" back is about average lift capacity. And thats close. But it could be more, could be less even on the same machine with some simple TL adjustments.
