Three point hitch draft control M4700

[Complete Turf Care]

As I had said earlier once you get the "lowering speed knob" unstuck and that fixed I'm betting the Position Control and Draft Control situation will be much different.

Today, I was able to get the 'lowering speed knob' to turn freely. It wasn't really stuck tight, but it was open all the way.

Unfortunately, this did not resolve the issue. I tried adjusting the lowering knob into many different positions and still could not get the 'position' lever to affect the 3 point hitch in any way at all. Not even the slightest.

I did use this tractor for several hours on last week with a fairly heavy attachment, and it got the job done. I do have more work with this attachment for this week on this tractor, because my Grand L6060 is down with a DPF issue.

I'm surprised. The lowering speed knob is not so loose that it may be doing nothing is it? Does it feels like it is doing something? [Internally I think it is moving a slider against a lobe of a cam-like shaft.]
It's been long enough that I have forgotten -- did you get hold of an operators manual for that tractor ? Anything specific in it about disabling or bypassing draft control? Very puzzling.

If you look at post #41 where you show a picture of the threaded rod, I would think one could just take that threaded rod loose, take it out of the picture and eliminate draft control interference as the cause (OR show that it was the cause.) Easy to try.

The knob does seem to be working. It did change the speed that the attachment drops.
I will try disconnecting the threaded rod. But I think it needs to be connected for things to work at all. I did not try adjusting the threaded rod today, but I expected the position lever to do something today. It did not.

Since the drop speed knob seems work, how did you raise the load in the first place ? If not using the "dead" position control lever it must have been using the Draft control lever.

Yes. The only way that I have ever been able to raise or lower the attachment is by using the draft control lever.

Man this intrigues me to death... while something COULD be broke I still bet it is a matter of figuring out how to disable the Draft control & once you do the position control will take over.

Is it possible that the draft control and draft control lever locations are mislabled? I know that's a longshot and I know nothing about your tractor but just thought I would throw that "out there".

I've noticed the comment a couple times in this discussion saying that draft control won't work if there is loss of traction. This seems like a "chicken or egg" thing to me in that if draft control is set "correctly", loss of traction won't occur. Right?

In other words, when operating in conditions where wheel slippage will occur prior to substantial loss of tractor RPM, the draft control would need to be set so that it starts raising the plow prior to wheel slippage occurring. Right?

The only problem with that is changing field conditions as you cross a field.

That's my point! Set the draft control for the WORST condition so you don't spin out. I'm under the impression that draft control is FOR changing field conditions. Probably shouldn't be plowing if there is no traction due to wet conditions, however.
