John Deere 4440 3 point hitch geometry and adjustment

First of all it's my first time posting on this forum and any forum for that matter, so bare with me please. I recently acquired a john deere 4440. It is the oldest Deere that we have in the arsenal, but seems to be a decent tractor and we were short on pulling tractors. My problem is that implements that fit well on our 7530 premium, older internationals, and a pair of JD 6400's do not seem to fit worth a dang on this 4440. The implements being a 7 shank v ripper and a V Ditcher to date, as I have not tried to hook up to anything else yet. The problem is that in the fully raised position the implements barely make it off the ground. Now this is not my first day on the farm, but I can't seem to get a handle on this old girl's hitch setup. Maybe I am missing something, any help or advice would be appreciated.
 
The first thing that comes to mind for me is to look where the top link is mounted. If you are running Category 2 machines the top link should be mounted in the bottom hole. Category 3 machines mount in the top hole. That could make a difference in how high the implement lifts. Mike
 
With nothing hitched to the three point and with it in the raised position, try and lift the three point arms up by hand. If they move up, maybe the linkage is a little worn and needs to be adjusted, did you move the load and depth lever to see if anything changes, just a couple things to check. chris
 

I'll 2nd what matthies stated of trying to raise 3 pt by hand after 3 pt has fully raised by hyd pump. Also check nut(parts key 39) to be sure it's tight as they've been known to back out affecting the internal linkage adjustment. Also the cab mounting doughnuts have been known to settle requiring adjustment of the external linkage to attain max lift height. Also try raising 3 pt with L/D handle in minimum setting to determine if internal L/D requires adjustment.

My 4440 is the best machine I own and I have much newer. I
am 6'4" and when I stand on the lift arms in the "up" position I
am eye-to-eye with anyone in the operator seat. They raise
plenty high.

I've got lots of Deere machines around here and I cuss their
three point for one reason or another. I think IH had that one
down way better from operator standpoint. I would second the
bottom whole comment for the third link. The connection is
mechanical for those, so have someone operate the linkage
(when it is off) while you stand behind. Look on the right side
just under the cab(imagine just under the operators arse) and
you will see the linkage moving. There are some bushings in
the pivots and if those are gone it will make lots of slop for you.
Having said this, I just worked over the hydraulic linkage on
the 7800 so it is possible I am confusing the two, but I am
about sure that is right. I haven't been out to the shed and am
still having my coffee!

You got one of Deere's best tractors be good to the quad shift
and follow the guide in the cab. That's an expensive repair if
you don't. The are very robust engines and tractors. The only
weak point is that stupid A/C compressor. Get ready to replace
it every two years. That cab is a crockpot without it.
 
If your top link has more than 1 position on the tractor and on the implement try using the lower position on the tractor and the upper position on the implement. The steeper the link raises from tractor to implement the better it will lift the rear end of the implement. That is just how the geometry of the 3 point works.
If your implement only has one top link position you might want to add another position by welding a piece of U-iron with 2 holes in it on top of the existing. I have done that on implements that I use on a much bigger tractor than what the implement was meant for.
