No. The draft control only senses the amount of pull on the lower implement.

Hmmm...not exactly and it's just the opposite. The bottom position makes draft control more "sensitive" to changes in the resistance an implement is encountering, and the top position is least "sensitive".

I've used draft control with my box blade and pond scoop. It helps reduce the amount of up and down adjustment I need to use on the 3Pt. When box blading, I'll push the 3pt control all the way down and then use the draft control to set how deep the blade digs in. This only really works well when used over long distances, say more than 20 feet. When it's working it's not really noticeable from the seat. To really see it work you have to watch the implement from the ground behind the tractor.
Keep in mind that draft control is only meant to be used with ground engaging implements. When using other type of equipment it should be disabled, and the draft control lever at the operator station should be all the way forward.
