DRAFT CONTROL How does it work?

[npalen]

Doing some more reading on the subject of draft control mentions the advantage of using it when plowing undulating terrain. Without draft control the plow would tend to gouge deeper when the tractor's rear wheels go thru a low spot. With draft control engaged, the 3pt would lift enough to maintain the draft setting.
I'm thinking that the draft control would also correct when the tractor's rear wheels go over a high spot by dropping the 3PT to maintain the draft setting. I suppose it depends on the type of draft control?

I am fairly sure that all the new machines with draft control will work the same. You may have different ways of setting the adjustments, but once set, probably all work about the same.

People down play those old Fords. But look what their competition was. Wayyyyyy more productive than the other brands that weren't even offered with a 3pt.

Harry Ferguson completed a series of USA patents on the various components of his Three Point Hitch in 1936. In 1938 he licensed his patents to Henry Ford. Later, after Edsel Ford, Henry's son, split with Ferguson, Ferguson produced Ferguson brand tractors in Detroit. Until his 3-Pt. patents began to expire, one after another in the mid-1950's, only Ford and Ferguson tractors could use Ferguson's patent Three Point Hitch.

Ferguson sold his tractor business to Massey-Harris, which became Massey-Ferguson, in 1953.

Note that there isn't any upward float with these which you need when brush hogging uneven ground, etc. when using a normal spool valve.

On the other hand, you have down pressure which could be very handy at times.

On the plus side, use a valve that has the float function and you then have the best of both worlds without having to pull their pin. :thumbsup:

The specs say it does have upward pressure, not sure if that is same as upward float?
THIS SYSTEM PROVIDES DOWN PRESSURE AS WELL AS UP PRESSURE WHICH IS RARELY
FOUND ON TRACTOR MANUFACTURERS 3 POINT SYSTEMS. BY REMOVING 1 PIN IT IS
CONVERTED TO FLOAT, MEANING YOU WILL HAVE UP PRESSURE, BUT NOT DOWN, WHICH
IS EXTREMELY USEFUL WHEN PULLING IMPLEMENTS ON ROUGH TERAIN.

Post number two is especially interesting.

I did not se that. Clever of them.

I think Glowplug did a better job of describing mixed draft/position control than I did.

I go to several shows , plow days ,etc . I have a 37 JD B and 44 # trip plow , 2/ 14 , This is a pull type , trailer plow . The B weighs 2750# and has 12. 5 at the drawbar . It will pull circles around those Fords . Do you notice all of the ford plows are mounted , so you can cheat ? The above poster is correct , scratching . BTW this plow will stay in the ground . When the ford starts spinning the wheels , it digs a hole and activates the cheater and away you go .
