I know this is an old thread but...
I was offered a 3pt PHD that is an old, gear driven model. I looked at it yesterday and it's in really good shape but...
It was built under the same concept as this. According to the experienced rancher who had it, where the middle "clamps" are, is where you attach the 3pt lower links. His has an upside down U shaped part in line with the lower link attachments that goes to the upper link. The front end of the lower arms attach to a bracket bolted to the tractor under the axle housing just inside each rear wheel.
I'm out of town visiting family (where the PHD is located) and can't look at my tractor. My ??? is if I would come up with a bracket (thinking larger sized angle or channel iron) to bolt under my axle housings to mount this beast to? It looks like a nice, heavy duty unit.
He called his a Dan Ussa? Don User? Something like that...brand. Course he recommended that I just get a handheld, but I need to do some holes by myself, so I think a handheld would be too combersome. He also suggested I could get a new 3 pt hitch setup and toss the system with the bars that go up to the axles.
I'm not familiar with something like that either. Unfortunately where I'm at all I get for internet is slow dialup on a borrowed old laptop that is slower than the dialup, so I'm running out of patience with searching the net. I drove my truck/trailer down to pick this up and am leaving tomorrow. I don't really want to load it up and take it home only to not be able to use it and have to bring it back (I get it as long as I don't sell it...) PLEASE HELP?!?!?!
