I recently purchased a ford 800 model 860, it is my first tractor and I am not at all familiar with it yet. I hear everyone talking about draft control, What is draft control and does the 800 have it ??? thank you in advance !!!

Amatt said: (quoted from post at 11:52:33 01/10/08) You may be right Larry. I wasn"t claiming that it worked, but that the vacuum was the theory behind it, at least originally. I thought I read it in my I&T, but maybe I read it on some obscure website (not ytmag.com).


I not only may be, I am right!!!! Think for a minute. What component would create this vacuum? How could it work in a system where the dogbone (pushrod) simply rests against the piston and is not attached to it? Even if the piston could be sucked in (which it can't) what would pull the dogbone in?

Vacuum and making the implement suck deeper was never even a part of the theory of the operation of the Ford/Ferguson 3 point draft control system. Whatever source gave you that idea was all wet!!!!

Amatt, with all due respect, a part of your statement is not true at all.

Draft control does not put down pressure on the 3 point. There is no such thing as vacuum in the lift cylinder, and even if there were the dogbone is not pinned to the piston. The three point hitch on these tractors is free to float up when ever it chooses to do so.

You are correct in that the third link spring is part of the draft control and that when the load gets heavy the draft control does act on a valve to raise the implement to make the load easier. When the load decreases, the third link spring returns to normal and pressure on the piston is released, thus allowing gravity to drop the load to normal depth again.

The response of the draft control is also varied by the position of the lift lever. The higher it is positioned, the lighter the load that it takes to activate the control and raise the 3 point. When in draft mode with no load on the three point, the position control lever does not raise the lift at all until it is all the way to the top of the quadrant. In that position, it should override the draft control and raise the lift arms all the way up.

There is more to this system, but that's it in a nut shell.
The little lever on the right of the hydraulic deck places the system in draft control mode when it is pushed almost straight down. If it's pointing forward it's in position control. In this position, one controls the height of the lift by the position of the position control lever.

All Ford tractors, at least from the 8N forward, have draft control if they have a three point hitch. Draft control on your 860 is engaged by pushing the little lever on the right side of the hyydraulic deck down. Unless you are moldboard plowing you need not worry about draft control.
You do need to obtain an operator's manual for your tractor.

Thank you Larry, I am in the process of getting an operators manual. What does draft control actually do ??

The three point hitch acts as a one-way cylinder in lifting the implement. Gravity provides the force to lower the implement. When plowing, or other heavy tillage operations, the implement may have a tendency to ride up and out of the ground when hard soil is encountered. The draft control attempts to apply down pressure by creating a vacuum in the lift cylinder that is transferred through the three point linkage to the implement. The depth of the implement is then governed by the draft valve at the top link. This valve, when compressed, routes the hydraulic fluid to lift the implement until the valve is no longer compressed. That valve acts the same regardless of being in draft control mode or not. But, when the draft control lever is in the down position (draft control is on), when that valve is no longer compressed, the vacuum is created in the cylinder again, pushing down on the implement.

The draft control removes any depth control from the operator and, in my experience, makes for a very uneven furrow and a rough ride. I prefer to do my work in position control, and I sometimes put the toplink in the lower hole on the tractor in heavy draft applications.
