Very nice! Better patent your idea, so they don't steal your idea!

I added some pins so it will be easily adjustable.

Good fix and as has already been said, "nice welds". This has been discussed before and there is a bit of agreement, "the lift pins need to be bushed up" and a bit of disagreement and that is what size to bush up to. Every cat one hitch I've messed with had Cat 2 size hooks. The bushings are simple, just get a lift arm bushing from cat 1 to cat 2 and put it on the lift pin, put your lynch pin in and leave it.
All of my equipment that I had originally outfitted with cat 1 pins are done that way, the newer stuff I simply put on cat 2 pins to start with. Some folks believe that a cat one QH uses cat 3 diameter hooks. I can't find anything that states that cat 3 is the correct size hook for a cat 1 hitch, If your does, well ok, none of my hitches do.
I think I may do to my top hook what you did to yours. I can hook to anything I have but some things would be a bit easier if the hook stuck out a bit farther. I'm gonna weld up the old holes tho'

My Harbor Freight hitch is for Cat 3. I have to use 2 bushing for each pin.

JD I match pins are Cat 3, too, I believe:
Optional iMatch Quick-Hitch allows for easy implement hookup


Upper bushing
Inside diameter: 0.76 to 0.77 in.
Outside diameter: 1.24 to 1.25 in.

Lower bushings
Inside diameter: 0.88 to 0.89
Outside diameter: 1.43 to 1.44

My Land Pride QH-15 (Cat 1) uses Cat 3 pins, upper and lower. I know the JD does also.

This is fun...
On page 9 of the QH-15 documentation

"Beginning with S/N 388293 and above, two 320-
048D lower bushings are shipped tied to the Land
Pride Quick-Hitch. Install lower bushings onto the
implement’s lower 7/8” hitch pins. This will provide a
tighter and more secure mounting in the Quick-Hitch
lower hooks."

The bushings are 1.44 inches in diameter which is cat three size. Based on this, would could assume that prior to the mentioned serial number the hooks were sized for cat 2.
HOWEVER!!!!
on the table telling what pin sizes are acceptable but the QH-15 it states,

"Various pin sizes up to 1 1/8” can be
securely locked in."

1 1/8 inch is cat 2. Even their documentation isn't standard. LOL

use whatever floats your boat.

Yeah, definitely... Use whatever. Cat 2 to Cat 3 is certainly better that Cat 1 to 3. The ball ends on stock lift arms provide a good fit on implements, so I try to duplicate that. I like to keep shock loads as low as reasonably achievable (ALARA... An acronym I despised from my old Nuke days) so I bush accordingly. But, to each his own...

P.S. Proof once again that we can never assume anything... The only difference with the serial numbers prior to the one you posted, is that the QH-15 came with NO bushings, as in "purchased seperately.," For what LP charges, a set of bushings to get you started is the LEAST they could add!

Here is some stuff I found on 3ph dimensions and I-match. I got cat 1 to cat bushings then cat 2 to cat 3 bushing with a pin hole in them for my adapters.
