Would someone explain the meaning of draft, position control and float control?

Thanks

Ernie,
Some other member could give you a better technical description but I’ll take a shot at the short version.

Draft Control: is normally used for ground engaging equipment like a plow. It will sense the resistance being applied to the implement and raise it if the resistance becomes more than you have the draft control set for. This allows the tractor to continue its forward momentum without losing traction. Some compact tractors have draft control but it is mostly seen on larger tractors.

Position Control: allows you to lower the 3pt hitch to the same height it was previously at. An example would be using a tiller and you are using your Position Control set on #3 to achieve a desired depth. At the end of a pass you lift the tiller and turn around for another pass. By lowering your Position Control lever to #3, you will be at the same depth as the first pass.

Float: lets a loader or 3pt hitch move up and down with the contour of the ground. Almost all 3pt hitches do not have down force and will always float up with the contour of the ground. A loader does have down pressure but most have an additional setting to let the loader float. This is useful when driving backwards with the bucket down to smooth loose materials on the surface.

Hopes this helps understand some of the terms. You may also want to do a search on the forum and read some of the other discussion we have had about these terms.

Miller’s simple definitions: /w3tcompact/icons/wink.gif

The draft control is used to control the depth of the implement below the surface of the ground…

The position control is used to control the height of the implement above the surface of the ground…

Float is used to allow the implement to follow the contour of the ground surface…

I am impressed with both the definitions of MarkV and JMIII. John's is certainly short and to the point. As often as this subject gets asked and answered with more confusion added than clarification provided, they have given some solid information. Still likely hard for some to follow, as actual experience with the three 'controls' is usually the most helpful.
For draft, when you are plowing with a 3pt plow, and see the response the 3pt arms make 'automatically' when the plow draws deeper, and the ag wheel bars spin out a bit of dirt causing the plow to go even deeper, after which (or during which) the 3pt arms lift slightly to raise the plow, giving the wheels a chance to re-gain traction, then see the 3pt arms lower a bit to let the plow drop back down - then you begin to understand draft control. With no draft control, one only can use the 'position' control to do manually what the draft control does 'automatically'. Now I stop for fear of adding confusion.
