I like it.

Very nice. The requirement for several hydraulic remotes gets expensive. Most tractors do not have that many spare remotes. I notice the unique set of multi-lever controls with 6 or more levers. Is that easy to find ? Is there any way to drive that set of multiple valves off a single remote? [That would make the whole system much more popular since many users have ONE remote available but not many.]

One key limitation of all the quick-hitches I have seen is width between hitch pins. Half of my implements do not quite match the width of the rigid quick hitch frame and worse yet, there is no adjustment for width. That lack of width adjustment (at least for a manual quick hitch) makes it harder or at times impossible to connect. So much so that I set the quick hitch aside and never use it.

I notice you are using one of the std. quick hitch "frames" and built around it. You have a very valuable innovation hydraulically driving the quick hitch. My first suggestion is to devise some means for left-right width adjustment between pin locations. That does not need to be hydraulically operated, just needs to be there somehow. I think that means getting away from the base quick-hitch frame or else modifying it. May be difficult.

By the way, how are you compatible with both Cat I and Cat II implements without any width adjustment ?

In spite of all those things I think you have a great set of ideas. Certainly thought provoking !

My Nordvalves have 7 remotes. For QH I have 4 if I want all hydraulic.
Qh can work with hydraulic toplink and hydraulic upper hook very well, but I like all 4 hydraulics.
My Nordvalve is serial with kubotas hydraulic, Very easy.
I had to pay about it 200 dollars.
Valves can be lead electric too.

My QH is compatible with both Cat I and Cat II implements
because it have hydraulic width adjustment and manual locking for it?
But then it needs cat3 hooks and bushings as you use in USA, or
the hook needs redesign as I show in picture below.

The width adjustment can be easy by hand lever because it is very light to use.
I made QH part after part and welded together.
The automatic opening and closing of lower latches happen when upper hook go up.

Nice design solutions for many of the quick hitch shortfalls. Great build quality - it looks very rugged - your craftsmanship shines. Thanks for sharing!

I see in the video you DO have a width adjustment in your system. Sorry I missed that in my first reading. That is a major improvement feature for any QH system and takes the whole thing from "impractical" to "very attractive." I also realize now that you are not using some commercial QH frame. Great job.

I still have one item of confusion: Does your multiple control valve unit (showing half a dozen or so levers and corresponding hydraulic hose connectors) operate from a single tractor remote control valve (RCV) port OR does it require several RCVs ? You mentioned that your control valve cost roughly $200. Can you say or show pictures a bit more about that set of controls ?

Tks.

Hydraulic remotes are easy to make to day. Tractor dealers and mechanics know best.
My Kubota 345 needed New Cover to Junction Block with Outline to Nordvalve 7 and Inline back.
So it needs no remotes itself. Se picture below.
This is my manual 7 valves
Nordvalves - Hydraulic Directional Control Valves P4

Here is some solenoid valves for remote control from cabin.
Expensive but easy to use.
summit-hydraulics.com/product/hydraulic-multiplier-kit-scv...
Summit ,they can multiplie from 1 remote to 6 remotes

Farm valve - Piippohydraulic

Go down of the side and find there the video
They can have 4 remotes + 2 for both stabilizer bars.

My next trial was to make lower links with quick couplers . Like Pad's or Walterscheid
To move the lower link from cabin I made this kind of stabilizer bar and lever to leveling bar.
Very easy to make.


Lower handle opens stabilizer bar and moving upper handle left-right
moves lower link right-left to proper place for hitching.



Here the yellow handle is for opening/closing the coupler.
My couplers are home made but works ok.

My NEW Weld on Euro Hooks and Balls

My next trial is to make Euro hooks for big tractors. And I use them from the cabin.
Not difficult but much to measure. Tractor was working hole time at field.
I drive 3 km to my outdoor smithy for welding and back about 10 times.



And my new video: Big tractor and Euro hooks.
