My input is, if you put helper springs on the three point, it will remove weight from the implement, which is usually not a good thing.  Find a way to put a spring on the actuating lever, and make sure you have a way for the three point to move UP without being locked into the down position.  That way you can use the weight of the hitch as extra weight on your implements.

Some systems used a lift assist spring, but it was kind of a balancing act getting the right tension.

Howard points out something interesting. "Float" is something they built in on the sleeve hitch bracket with a slotted hole in the lift bars.

Something to think about at least.

MF10 and 12 sleeve hitch. slotted lift straps.

MF14 and 16 3pt hitch. slotted piston rod end.

As the guys said, that "float" function is important.

Sort of a shock absorber, if you snag on something.

Thank you all for the suggestions about helper springs.I found a solution and I think is good.After installing the springs at the lever the mechanism is working much easier.

I made 2 small videos to see the 3PH working.

Keep in touch.

Glad it's working like you had hoped.
When you first start using the plow, keep the thumb button depressed so it can float.

The only thing that may be a problem is the geometry of the top link.  As you lift, the implement, especially a longer one like a plow, the rear of the implement will tip down as you lift almost as much as it lifts upward.  Notice how your tower of your toolbar that goes up to the 3rd arm tilts backwards more the higher you lift.  When all the way down, it is 90 degrees from the ground, but tilts quite a bit up top when lifted.   It should actually tilt forward just a bit.

I wonder if moving it to the lower hole on the front mount point would solve that Daniel?

The tower on the toolbar is so close, no matter which hole it's placed in, mid lift will kick it backwards as the 3rd arm is parallel to the ground.

Yes , I noticed that the implement support is not constant parallel with the ground . I tuned that when in down position the plow will be parallel to the ground , when in upper position it has not so much importance. This problem is becouse I took some elements for this 3PH from my old homemade tractor and adapted it. I know that this problem could be solved by moving the pivot hole . Now is night here (almost midnight) and I cannot make noise in the yard - becouse of my wife !!!

Thank you for the observations .

I had redone a tractor lift due to adding a pto gearbox and had the same issue, but not nearly as much a rear slant as yours.  It wouldn't get the plow above ground level, but then it was a sleeve hitch with a 3pt adapter, so made the plow long.  The shorter the attachment, the less it will affect it at the rear.

Depends on how long the plow is really.  You may have a problem getting the rear to clear the ground, but then you have a high lift range, so it may do just fine.  All certainly looks plenty strong!

Problem solved .

Down , the tower is vertical:

Up , the tower is slightly tilted to front :

Did you lower it one or two holes?

One hole . When I lowered two holes the tower was tilting too much in front and the 3PH wasn't rising to the top .
