3 Point Geometry

[WinterDeere]

My desire to add a hydraulic top link to my pallet forks was one of several drivers in my decision to buy a new tractor this year. It’s really tough to use pallet forks without any ability to easily adjust tilt on the fly, IMO.

Most tractors have the connection point for the lower arms under the rear axle and the top link is at the rear of the transaxle housing which makes the top link shorter.

Thank you, I didn't know that. Thanks for correcting my over simplified statement . As you can see on my Kubota both connections hinge just behind the rear axle. They are both like that. It makes setting the 3 pt up easy. Just think parallelogram if you want level travel.

I think if the OP would attach his top link to the tractor in the bottom hole instead of the top hole, it might help. Also if he can get a higher attachment on the forks for the top link. He needs the top link to "get short" as the 3pt is raised by lowering the tractor end or raising the fork end.

Before welding it,I "mock up" by sitting empliment on ground then on blocks to simulate lowered and rised positions. That shows where lift pins need to be mounted.
I'd love to find forks like those at twice what you paid.

One other option, if your three-point arms have the ability you can move the attachment point from the lift rods in to the hole that is closer to the tractor. That will get you more lift height, but you will lose some lifting capacity..

In the picture above, the lifting rods are in the hole that is farther away from the tractor to get a little more power, while sacrificing lifting height.

I'm already in the inner holes, the 3 point just doesn't have much lift, although drilling another set of holes 2" in wouldn't be a horrible idea...

I get lucky on auction items every now and then, got that for $20, rear dirt scoop thing for I think $35, box scraper for I think $50, 5' King Kutter I think (an FM60) finish mower for $75 (needed blades and spindle bearings...), 5' Massey 3 point adjustable disc for $200 etc...

I also found it difficult to get it right. I aimed for the top hole, but the middle hole gave the best result. An other thing I did not anticipate is that when you lift a load, the tires bulge and the angle of the forks change, and also the max height becomes a little less.


When I made the fork attachment I welded on "hooks" , so I can also use it on the front end loader.

None of those reference dimensions help this situation in any way.

actually they kinda do, on the second one it shows top link spacing 16" to 21" for their quick hitch, which goes with this issue since I made it 16" so I'm obviously on the bottom of the scale so it barely works...

Bert, I like the folding forks, nifty!

I was cleaning my garage yesterday and found a chunk of chain that should work, just gotta find a chain grab hook now, for some reason I have a couple loose 1/2" hooks but nothing in 3/8"...
