Draft Control Adjustment

[jesnic]

The draft control on my 1500D is controlled by the lever. Just pull it out and slide in back in the other hole and it rides on a concentric cam the measures hydraulic pressure and makes adjustments to the lift. The adjustments are so small, you probably would never see it.

Hey Mickey, what is the small 1/4" rod sticking out horizontally under the cable? It appears to be the opposing end of the lever attached to the cable? If so, is the draft manually adjustable to presets for other implements?

Jesnic, what is that little handle up on the side of the control valve? It is turned back.

Winston, that little level controls the drop speed of the implement.

YM2000 has Position Control which raises the 3-point automatically if it leaks down. It doesn't have Draft Control like a Ford or Massey, which I think is designed to lift a plow when it is making too much drag.

YM2000 has a linkage like in Jesnic's picture, except with two separate holes. The manual (YM240) says don't move it to the other hole. Look at his second photo above: if the 3-point arm drifts down, the rod linkage pushes on that button coming out of the hydraulic control the same as if you had tugged on the 'raise' lever on the right side of the seat.

I'm with California:laughing: And Normy Thats correct my 2000 is set up Identical. Never messed with it And I believe my thinking was it was a stop wich pushes the lever forward in turn holds pack the finger stopping the lifting.

Is it possible that the YM2000 has an internal cam attached to the valve so that the lift arms will raise or lower with pressure or lack of? Same as mine, but everything is internal in the valve. Just thinking here.

I'm going to make one more statement about this and I'm done. I don't believe any Yanmar has a draft control "unless" it has the 2nd handle by the lift handle.

Wow, I didn't intend to start any arguments.

First, to everyone who replied trying to help, thank you.

Second, I apologize Normde for using the wrong terminology. I am familiar with draft control and was told by an employee where I purchase parts that this was draft control. All I was trying to do was ensure that whatever this is was properly adjusted and functioning.

Third, Carey I do know the difference between my three point lift and whatever this is. And you're correct, I'll be much more carefull with any future questions.

I'm assuming you're talking about the 2nd pic. The rod transfers the movement of the drag back up through the cable to the arm near the upper 3pt arms. The draft control, the lever next to the 3pt lift control, does set the sensitivity, or the position of that upper arm to determine where the neutral point is. The drag via the linkage will set the position of the arm so as the drag moves up/dn it changes position of the arm thus determine if the 3pt arms need to move up/dn or not.

I've not found any other use of the control. Would think it quite difficult for this design to control the depth of something like a plow.

Hope that answers your question.
