![]() A lot of Ag tractors will have a third lever called a sensitivity control lever to adjust how sensitive or how often the three point hitch makes these minor adjustments on it's own. Most tractors sense the pull through the top link by a little hydraulic control cylinder behind the top link mounting bracket, but some tractors do this sensing through the lower three point arms. The other function that draft control has that ties right into this is a sensitivity control that automatically raises the plow if it starts to run to deep. As you continue to plow the field you make minor adjustments to the draft control lever as needed for plowing depth. What you get to the end of the field you pull the lift lever all the way up, but don't move the draft control lever, that way your plowing depth setting is retained when you start the next furrow, again putting the lift arm lever all the way down. Take a plow for an example, when ready to start plowing you put the three point control lever all the way down, then adjust the draft control lever to the plowing depth desired. For proper use while doing field work, the three point lift lever should always be all the way down and the working depth of the implement set with the draft control lever. Only found on bigger ag tractors, the draft control lever has an important purpose in three point implements, it controls the height/ depth that the implement is working at. I was browsing old posts and stumbled upon this question on 3 point draft control that didn't seem to have a clear answer for someone trying to figure out draft control. If you ever did find yourself having trouble pulling a planter though, you could quickly adjust the draft control to raise the lift just prior to loosing traction. The drive wheels are doing more to maintain depth and handle ground contours than the lift can, and the coulters are not going to create enough drag to break traction under most conditions. I don't worry about draft control with a planter. If the bush hog starts to dig in it doesn't take long before the lift will raise slightly. I do like E-308 in that when I am bush hogging I use "float" mode which is basically just putting position control down to the level I need it, then pushing draft control all the way forward so it takes the minimal amount of tension between the bush hog and tractor to raise the lift. Think of draft control as managing the amount of tension between the implement and the tractor before the lift starts to raise- thereby lowering the tension until traction is regained. As the force on the implement increases it will eventually reach a point where the tractor looses traction and starts to spin. It is going to be more helpful when you are pulling something like a bottom plow, v-plow or a disk that is near the upper end of what your tractor can handle. The main thing about draft control is to manage the lift to maintain traction in hard/soft ground. Should I do that then adjust the level of the planter with the center link? My tractor manual says float mode is established by pushing the draft control lever and 3 pt position lever all the way forward. On top of that, should I use float mode more often than I am? I don't think I've ever used it for anything, but it makes sense to use it for the planter so that it can more accurately follow the contour of the field. What is a ground engaging implement? I know the obvious ones like plows and discs, but what a about a 3 pt planter? My understanding is that when using "Ground Engaging Implements," the draft control lever should be engaged (and adjusted to the desired setting). I have read the manual numerous times, and it sort of makes sense to me, but I'm still not 100%. One thing I don't fully understand, however, is how to properly use the draft control lever and float setting on the 3 pt hitch. ![]() I have a lot of experience on various tractors over the years, and I feel like I generally do a pretty good job with my projects whether they be bush hogging, discing, planting, or spraying.
