Debating POSITION CONTROL. What is it to YOU?

[trktrman]

This is not about knowing every single facet of how every single brand performs PC. Let's be very clear about that point.

This is about establishing some kind of framework, a definition that defines WHAT, position Control IS. That is completely separate from how one goes about accomplishing it. There may be 10, or a 1000 different ways to perform "PC". But until we can all agree on "WHAT" PC is, then talking about how to get there is pointless. Your comment in my opinion is quite missing the whole point of this thread.

There are those out there, I will Reference TrippleR, And Murph1234 as two people that have specifically expressed PC as being a function of a "Self Adjusting Circuit". The purpose of which is to compensate for Drift. So let me get back to an example I was talking with Trip about.

The GC1710 is said by many NOT to have position control. This was a question at the time because based on what the dealer told me, specifically concerning using the Tiller and controlling the depth of cut, that the three point hitch is used to raise the tiller to the desired height for tilling. Thus,,, PC. TrippleR then stated that the GC1710 did not have PC because it could not adjust for Drift. IF,,, you accept the explanation from Johnson City Kubota LLC as an accurate description of PC, then the GC1710 indeed has PC. So as have been stating repeatedly, this boils down to WHAT PC IS. Not trying to figure out 1000 different ways to accomplish it. My question is MUCH SIMPLER then that.

The Massey GC1710 can not both at the same time,,, HAVE PC, and NOT HAVE PC. It is one or the other. Can you speak to this JJ?

My opinion is that PC can be stopped at a particular position each time with no load sensing
Load sensing sounds like draft control to me.

Kubota is something for sure. There is a center neutral position, such that even though you can stop the 3pt hitch at an infinite number of places on long the length of its travel, you can't place the lever in any position that allows you to identically match the same height adjustment every time. So if we are using this definition of PC, simply being able to stop the 3pt at any place along the way is not good enough. You have to be able to place the lever in some specific position that recreates that height adjustment every time. A center neutral lever mechanism does not allow this.

Kubota does have some tractors with position control, where you have a scale and numbers on the lever that indicate position of the hitch. That is to say, there is a correlation between the lever setting and the hitch position.

They have other tractors that do not have position control, where there is an up and down direction to the lever, and it will return to middle (what you call neutral but it's just the default center position of the lever). There is no correlation between lever position and hitch position at all. You move the lever up and the hitch moves in the up direction, and vice versa.

Both systems let you stop the hitch anywhere along it's travel. With position control, the hitch position corresponds to the position of the lever. Without position control, there is no relation between the hitch position and lever position and it's up to the operator to pick the height via eyeball (or counting taps of a quarter incher if they have one).

Oh yes I do know and how it works also the other 2 systems.

And thank you sir.

We are getting a few people to come out on one side or the other of this. I intend to refer people back to this thread when this topic comes up in the future. Because it always seems to come up.

Ok, What?

I should note that Kubota is not alone in offering both types of hitches. Take a look at the Deere 1023E (no position control) and 1026R (position control). Deere very clearly markets this as a "premium" feature in the 1026R.

Just reread what has been said no need to write it all over again. It's all there.

EDIT: You changed your original post lol. So I am now changing mine.

As I said, I think you and I are on the same page. Thank you for your input.

I am not up on the Deere as I am not fond of them. Can you tell us all what the difference is between the two models? Why one is and one is not? or more to the point, how one is and how one is not?

I am not going to go around in circles with you. That is not the point here. You have said nothing conreate one way or the other. If you understand how PC works, then just spell it out and be done with it. Others have done so. If you don't care to, then just drop it. You are not contributing by posting stuff like ^. Thanks
