You need balast or you will trash your front axle!!!! really?

Quite possibly "that" picture was staged, but fact remains, a small tractor can indeed drag a load too heavy off a trailer and end up in the same situation.

Or worse !!

How would you explain that fork angle in a real case. ... Doesnt look broke.

 

[LD1]

The tractor is small enough that it is unlikely to lift that load even enough to drag it off. Rather the forks would just slide out and leave the lumber on the trailer.

But a bundled and banded load of wood, and significant curl back to scoot the load off the trailer without the forks slipping out, it could have started with the load tilted back pretty far.

Clamp on forks dknt have much curl power, but ssqa or pkn on forks, and loader up high, curl would have no trouble curling a load far too heavy to lift with the loader.

And/or in a panic, when the tractor started to nose dive, grabbing the joystick to "hang on" and pulling towards you on the way down do end result in that situation pictures as well.

But most of the time....you're right, the forks would dump and crash the load or pallet

For heavy loader work you're right and that was the point of my first post. A 2000 3pt weight box only takes 1,000 pounds or 15-20% off my front axle during a heavy lift. (assumes weight box CG is 3ft behind rear axle and wheel base is 6 ft; assumes)

Glade, it would seem 2 other numbers effect the weight shift change percentage and efficiency to your calculation:

1. How far forward of the front axle is the load.

2. How high is the load (thus effecting cog)

Yes, and no (in an static senario at least)

To expand on glade's "no" to #2, because gravity acts straight downward, only horizontal distances can function as a lever arm for weights/loads/ballasts. Vertical distance (height) has no horizontal component, so it will never figure in to this problem.

Doesn't the horizontal distance forward of the front axle change as the height increases?

Interesting picture.

Way to small of a tractor and with a light PHD on the back to boot.

What is that? a Full bundle of treated deck boards? 2500-3000# assuming only 8' boards?

How is it that we have not heard a suggestion from the axle waxers to screw the post digger auger into the ground in order to hold down the back end of that tractor ? Seems a shame that good ideas are going to waste...

Yep, changing from a force to a fixed point behind the axle would change things enough for another 30 pages.
