No more 3-pt hitch

[nomad]

but, infinite point hitch.

Don't you think same? It is time to do a revolution in attaching the equipments to tractor. Actually, Europe has already started this many years ago. Called A-frame. (We also manufactured such an A-frame of tousands of pieces since last year. See attached picture. There are different versions. Another version in USA is Delta Hook?) It's very useful.

Time to revolute. Red part will be built-on tractors at the tractor factory and grey u-section frame will be built-on at the equipments factory. So, no more quick 3-pt hitch problem. No more force on 3-pt only. Infinite point contact. There are millions of engineers and experts in the field. Why are they not thinking such simple things that we can easily think of?

Advantages and drawbacks of A-frames over 3-pt?

Ground engaging attachments such as a box blade, regular blade, earth plow- The top pin is the only thing holding attachment in the vertical & added weight to the 3pth or implement because of the New structure. Other than that looks like a good design , Or maybe I'm missing something? Also is a pretty close design of the Quick hitches on the market now.

I like it. Time for a change.

Isn't that more or less a Freedom Hitch

I can only think of two problems...#1-Which size do you choose? At present you can use an implement that is too big/small for your machine with simple addapters. This could be overcome by attaching the new style to your old 3pth.
#2 With the current 3pth I can create my own implements as needed. Throw on a set of pins and I'm good to go. This new style would take a lot more work to build a simple ballast box/tow bar or whatever....
It does look like it would be real easy to slip one implement off and another on though....

When size/weight matters we have "pull" type attachments. "Pull" (tow) connection isn't cancelled with this A-frame which will be built-on the tractor at the factory. If an implement can be "hanged", A-frame can be used for all types of hangable implements.

You can still create your own implements with this A-frame. A-frame (red part in the picture) dimensions on tractors will be standardised anyway. All you will do is to add a gray u-sectional part (female part) to your implement instead of adding classical 3-pt parts (pins, etc.)

If you look at Delta-Hook's A-frame, it looks better and easier to make their female part. Ours is heavy type; its weight is 120 lb. Anyway, adding the female part of a-frame is easy. Just plasma cut and bend and weld it onto your implement. Anyway, male part will come with the tractor.

How's the clearance for equipment requiring a drive shaft the rear PTO?

 

[nomad]

Egon, it is not season of laughing in green. Grass is yellow now Smile in yellow.

Clearence between equipment and a-frame when running pto shaft? There is no problem in that. I don't have a video clip of mine when operating, but, Delta Hook has a video clip on their web site. Do you see any problem there?

I'd have to see how it goes attaching the PTO shaft. I've real problems with attachment schemes that don't allow room to get to the PTO area. Newer isn't alway better. bjr

ok my two cents from some expreineces.

First the way the frame attaches at the bottom of the a frame on the attachement side. With the brace coming in you will have a leverage problem and a point for fatigue. That needs to be attahed directly to the frame. The 2 lower arms bear the most of the pressure so you do not want anything with leverage when the tool binds up.

Second, you do not want the top of the a frame above the third arm. This is going to cause a tourqing issue that will attempt to push the arm down in a clockwise circular motion. Making a issue that will be hard to resolve once it happens. Search for the guy that had it happen with the box blade.I have done this numorus times with 3 point implements and speak from experience. The High above the pin the more dramatic the effect.

Third this deisgn would be fine for say up to 40 maybe 50 HP. After that the a frame on the implement side will be way to weak to take the typical bouncing when in the up position. 40 below i think this would be fine with some minor tweaks as time will tell.

Also the distance that you have it going back to the tool is going to drastically decrease the lifting capacity of a lot of CUTs or SCUTs. for every foot you will loose typically 500 lbs capacity depending on the tractor. You need the tool to mount as close to that a frame as you can as to not change the dynamics of the lift and leverage.

Otherwise i love this idea. I would try it myself. Dont take the above as slamming it. I think with a few tweaks you have something that may be a patent in the making. Keep us informed
