V Teks Loader/ Hydraulics Questions

[winston1]

Well Hoye's knows a lot more about these Yanmars than I do but I thought all the Yanmars had 3 point lifts that could be raised to any height disired and hold it at that height. Only one I am positive of is my ym2002d and it will hold at any height from bottom to top.

Yeah my 3 pt is the same as Winstons it will hold wherever I stop the draft control also and move infinate increments up or down so Id say that is the way they are supposed to be when working right and thats what I expect it to do.

Now when the little lever on my auto draft is flipped it is supposed to lift the 3 pt when the drag gets too much but the 3 pt still acts pretty much the same its different on the down but still holds where I stop the lever. (if that makes any sense) I have not really played with it much my straight runs with the tiller or plow are only 100' at a time so I just adjust the 3 pt manually by the draft lever. fwtw

As far as your problem Scotty in my minds eye shortening the reaction rod is where I would start so as the 3 pt gets to the top it is not pushing on the control however yours does that I am not sure.

I have a different set up but works the same so I kind of get whats going on but cant offer a real solution just ideas sorry.

THANKS Winston - I spoke to Hoye the other day and they said that it was more like number 1, but mine sure doesn't act like that and honestly, I like the ability to raise it up in increments so I am glad to hear that its number 2.


Hoye did confirm that when the 3pt hitch is up and wanting to move upwards and cannot (like mine) and the loader bucket is calling for fluid, that it could be dead heading which is not good. So I am going to try to make that adjustment this weekend...Thank you for the photos too!

Oh...Hoye thought that the pump I have would provide 9 gpm - so the pump should be able to handle this.

I think Hoye misunderstood you. If you pull the lever just a bit up on your 3pt you should move just a bit. Like winston said mine tops out before the lever is all the way back, but still like 85-95% of the rull range of the lever before its topped out. If as soon as you moved the lever up it went all the way to the top it would be impossible to control the depth of a box blade a plow that was running to deep or a bushhog height to mow. there wrong on this. It works like your #2 senario you listed.

I had my mine out of adjustment. When I raised the lever all the way up, it would load the engine ( like it was still trying to lift but was all the way up) I have a stop on the lever that I adjusted to keep me from moving my lever too far so, it won't do this. But, like others have said, mine will stop at any height & hold there

Mine will do this, i just make a habit to not pull it up all the way. I think you can adjust this, im just to lazy to do so.

So i just pull it up to about 90% of the range of motion. After several years i dont even pull all the way to the back anymore(actually after several weeks of using it).

If I'm understanding this correctlly :ashamed: Easy Fix even for me. When your Arms have "Almost" reached thier highest point that where you set the Adj. nuts on the Cam to your Linkage to pull the plunger away from the Hyd.valve. No mention of this Adj. All you need is a pair of pliers.

Cardoc - interested in what you said...I thought the draft control had to have an implement like a tiller that put pressure on a spring to make the draft control work.

I have draft control but it does not seem to matter where I set it.

As for Hoye - I love those guys - so I do think we had a disconnect, but I had a long conversation with them and I was pretty surprised when we discussed it. Because I was really concerned that I had a BIGGER problem that I thought.

He said that when I pull up the 3 pt lever, there will be a point (he said about halfway) where it will raise all the way to the top. He suggested I install a screw or something similiar to stop the lever or adjust the linkage. I intend to adjust the linkage and if that won't work - some sort of stop mechanism is next!!

The Yanmars with draft control have two levers, the outside one is to raise or lower the 3 point. The inside one is the draft control lever. The Yanmar draft control is only activated by a cable that goes back to a tiller. I will attach a thread here from Mickeyfx. He is the only one I know of that has it hooked up and working as disigned. http://www.tractorbynet.com/forums/yanmar/105695-auto-tiller-controls.html

Sorry about that. I'm not sure who you talked to here but I'm pretty sure something was misunderstood one way or the other. We'll have three point school Monday just to make sure everyone here is up to speed though.

You should be able to raise or lower the three point and stop at any position. They do use a valve that is either raising, lowering, or holding but the linkage determines where you want the three point to be and moves the valve to the necessary position.

Sorry for the confusion.

Aaron - I am sure it was me that got it confused.
