Non Specific Brand Draft Control

Correct. That is why true "draft sensing" is superior to Ford/Ferguson upper link style. I'm not aware of anything anyone did to make an upper link system work with a semi-mounted plow. Even a MF 1100-1130 were upper link sensing ??

We had a hitch that was mounted to a 4 bottom Allis Semi mount.

We used it in conjunction with a MM 670 top link sensing tractor. It didn't work very well. Dad sold the 670.
Bought an XT190   

This is an interesting dilemma.

When I plow I encounter about every condition you can imagine. From the easiest going to rock hard red clay to steep hills ( of rock hard clay!) alfalfa, mud….I’ve owned a couple tractors that really aren’t all that big (70 and 77 Hp), that if ballasted pull 4-16’s pretty good. The 77 horse is a MFWD, and it pulls it great. Yeah those clay hills can put it on its knees, but for the most part I manage.

Anyway, these 2 tractors are both closed center hydraulic and lower link sensing. The newer one is a 1990 model year. Anything I look at now in 85 HP range give or take is open center, top link. If you aren’t careful, you’ll find that Hp tractor in a 3 cylinder, often 2000 pounds or more lighter than it should be.

Hard to deal with.

I would have had no idea what that was for, and cut it off one of mine because it was in the way of proper adjustment. Found a video on youtube from "That Oliver Guy" talking about them and the different features. It's possible other brands had something similar. For my money, I like the Allis system. Have not had enough opportunity to plow with my Red tractors to have a good opinion of their draft sensing. Hopefully will get some seat time this fall with the 856!

Interesting. It shouldn’t really matter what color anything is for this arrangement to my way of thinking.

as if on cue!

Location within a location. I’ve got spots so hard at times you’re lucky if the plow is in the ground. I should have said, I get along good with 4-16’s semi mounted “for the most part “. Of course when the plow does nothing but skid across the ground it doesn’t take much power at all!

So I wonder, did this quick hitch have the plow pull pins below the tractors draft arm balls?? so the top link would be getting forward pressure against it ?? I guess that should work. I saw someone make an MF post about the Super 90 tractor had draft arm sensing and then the "new" 1100-1130 went backwards with top link sensing.

Tbone95 and all who are interested


Here is the top sensing hitch !

Simple hitch honestly.

This hitch came with our Allis plows back in the 70's.... Plows are long gone but Dad saved the hitch. Wish we would have kept the plow draw bar too as it acomidated the large holes in this hitch but it went with the plows..   

The large holes in this hitch whet over the plow hitch and a standard 3rd point went to the usual place on the tractor which senced feedback pressure. THE tractor we haD at the time was a MM670.

I belive Dad bought Allis Plows with the MM670 which would make sence why the plows had that top sensing hitch.

Shortly before we sold the MM670 remember dad cussing and cranking on some screw on the back of the tractor and FINALLY the draft control started working.

Then we bought an XT 190 and this hitch was not necessary.

Enjoy the photos.

John Deere 2 cylinder 20/30 series also needed a top link as they to used the top link for draft. Deere liked to copy and they must have thought Massey/Ford were the ones to imitate. Look where they put the engine on their combines later on.

IH's fast hitch was ok until all its moving parts got so sloppy the sensing rod couldn't send an accurate reading to the tel a depth valve.

Copying, lol, well it’s a three point hitch but really only 2 choices!
