Default Three Point Hitch Adapter

So I have had this need and idea floating around for awhile and now the need
has arisen to build it. Actually I need to move my gooseneck horse trailer and
my buddy needs a generator moved.

I have the 2"x4" tubing, 1/4" wall here in the resource pile, the 3/4" x 4" A-36
flat bar was purchased yesterday. I got all the flat bar cut up and drilled last
night, tonight will be the tubing cutting and milling.

Correction: 3/16" wall not 1/4"

Then the welding, then hardware mounting.

I will be making 2 of them as my neighbor wants one of his own.

My 3 point hitch, lower lift arm height is 7" and the upper is 32.5".

This should make moving things around much simpler.

So should I paint it Ford Blue or Black?

Nice strong and simple design.

I'd imagine the cat1 pins will bend long before any of the rest of it

Does that design that has the ball hitch boxed in allow for enough room to get a wrench on and off. Looks like a box end yes, but an open end?

Other than that looks great.

Wrench??? WTF, that is like... Work??? There is enough room for my
impact and a 3/4" drive socket... It was even planned that way...

Yup, I would agree. Cat 1 forged pins. They should hold what I want
to lift. My only question is how much front mass will I need for picking
up the gooseneck trailer....

The plan, build it once, paint it every 10 years. Use as needed.

I made one almost identical, but kept the steel sizes a tad thinner. As it is, 1/4" wall tubing, 3/8" plate and angle, it's a pain for me to put on.

It's used by an Uncle to move a 16' goose neck dump trailer loaded with 6 ton of coal for us Smiths.

Got some pictures, all the tubing got cut, and ended beveled for welding.
The 3/4" flats need some of the corners cropped off that will happen later.

I started milling the pockets for the receiver tube, it was slow but turned
out spot on. I set the DRO for 0,0 in the center of the square and then all
I have to do is cut from +0.925 to -.925 in x and y and I get a nice square
hole with 0.375" radius corners the hole is 2.550 square just a tad bigger
than the receiver tube.

I drilled a 1/2" starter holes as my indexable carbide end mill is not center
cutting. My first side I milled 0.050" depth and took 4 passes on the tube
(BTW, it is 3/16" wall not 1/4" wall as I mentioned above) on the second side
I did a full depth of cut. It was overall faster so I have 4 more tubes to do...
