 What is 3 point hitch draft control?

I asked this question in another post on a different topic, and thought it'd be better to give it its own title since I received no responses.

I'm looking at smoothing/grading soil, and was told that draft control would be something great to have for this purpose, and others tell me it would do no good (that it causes implements to hover above the ground). Essentially, I'm trying to find the best way to keep implements from rising off the ground when going over a hill or gouging the ground when I go into a dip. Thus, what is draft control, will it do this, and if not, what is the best way? Just play with the hydraulic lift lever as I slowly move forward?

Draft control will probably not keep your implement from rising as you describe. Draft control is used to do what it says, control the draft of the tractor. Draft control changes the position of the implement to reduce the draft on the tractor, or the amount of "pull".

The best way to keep your implement from raising off the ground is to give the 3pt lots of float, or lower the position past the point that you want the implement at. Takes some time and practice, and take it slow.

Draft control is just what it says! It controls the amount of load that an implement puts on the tractor. For your purposes it should work fine. For proper use, the lift lever should be all the way down and the depth set with the draft lever! There are other differences! The amount of load that it takes to change the draft! I'm not up on the spec's of all the new tractors but I remember going 20 horsepower light on a demo of a 100 horse farm tractor and yet being able to out plow as our tractor only took a 7% load change to monitor it and the competition took just over 20% load change for it to move!

I have an additional question on this topic: How does the flow control to the 3pt factor into controlling the finish or use of a rear or box blade?

 What is 3 point hitch draft control?

I'm still not quite following you. First of all, the word "draft" only has a few meanings to me... the first being a small current of wind due to a slightly opened window, and the second being an involuntary call to duty to serve your country. Thus the reason "draft control" isn't too definitive to me.

Secondly, I understand adjusting the depth with my 3ph lift control, but how does draft control control the load on the tractor? Or does draft control reduce the required uplift from the ground via hydraulic control to make an implement "float" above the ground? In other words, think of it this way. My box blade weighs around 700 pounds, and if I drop it down it cuts the ground like a hot knife through butter. With draft control, does it essentially create an adjustable buoyancy of sorts that allows me to maintain a down pressure from my box blade in the range from 0-700 pounds depending on where I set the draft control?

Jon, think of 'draft control' as a form of 'auto-pilot' for the 3pth, you set it to a particular point and the draft control maintains it there.

In ag. use the draft control would be used to, for instance, keep a plow from digging in too far and stopping the tractor. Instead when the load got too great it would automatically raise the 3pth, and the plow with it. The system uses a sensing mechanism connected to the upper link of the 3pth, when you push or pull against the upper link it moves a valve that remotely operates the two lift arms that the implement hangs off.

I'm not sure that you could get the draft control sensitive enough to do what you want but it theory it should, you might need to work at a slower speed to allow it sufficient reaction time that's all.

BTW, draft also means pull, or work, as in draft horses.

Best of luck.

BTW, draft also means beer. I'm ready for one right now. It is noon somewhere.

Given Yooper's slant on "draft" it certainly would put "draft control" into a whole new perspective now wouldn't it?

Actually, "Draft Control" is the proper and skilled techniques of managing draft deferments and selection of National Guard or Reserve military units to join. ;O) Just kiddin' guys! Don't tar and feather me.

You know--I shouldn't even be allowed to *own* a tractor for overlooking what yooperpete said--the use of the word "draft" with "beer". If anyone should be tarred and feathered you're lookin' at him!

Okay--here's another question. The 3ph lift control on my tractor seems to have a VERY narrow band of operation. I have to lift it almost 1/2-way up before it pulls something off the ground. As a result, "fine tuning" with the 3ph lift is pretty darned difficult. Can this be adjusted? Is there a better way to do this? Also, the control doesn't slide very easily making adjustments pretty jerky.
