1/4" Valve Haters---Read This

[Giles]

Based on your description, you have the QI model. You can still be wrong even at age 64.

If you think I have QI ---Good for You---I have no problem with that:thumbsup:[/B]

EZ guys geez one of the things that makes this forum nice is that everyone is polite - Well except Diez.

REALLY
I am 64 years old and I have owned, no less, then twenty tractors! I think I know how a tractor lift system works.
First--My post is intended to possibly help someone that dislikes the QI system. Read my post again:thumbsup:
Second--It makes no difference if I pull the leaver to me or away because there are NO stops, other then the adjustable ones that have only ONE STEP.
Idling, or wide open, the lift works the same. I can raise the implement slow or rapid, 1/16" or 2" depending on how fast I move the leaver.
If you think I have QI ---Good for You---I have no problem with that:laughing:

Take a picture of the control and post it on here. That should settle it.

Agree completely.

I can understand the confusion on the QI as the different models have different set ups. Some have adjustable stops and some don't, some work OK and some just so-so. Yes, I am one of the haters.

I believe Giles has position control. I thank him for sharing his oddity and giving hope to those who just don't like the QI system that it might be a simple change to convert a QI to postion control. My B7200 had postion control and my B2620 has QI. Unfortunatley I never compared the two when I had them both at the same time to see what was different between them. I think this thread got a little derailed by all the QI setup questions. If Giles hasn't been run off I wouldn't mind seeing some pics of his rig so maybe we can see what is involved with converting a QI to postion control.

Thanks Giles for sharing, :thumbsup:

I am inclined to agree. I am also in my 60's and have driven tractors from an early age and certainly know the difference regardless of what the logo on a control shows. I have tractors with both.

Retrofit may be possible on certain models since some variations within that model has position control such as in the Bxx30 whereas the Bxx20 doesn't. This "may" not be possible in the BX, but if it is, sign me up.

TripleR and BrierPatch---THANKS for appreciating what My post is about:thumbsup:
I have made photos but have never posted a picture---I am working on that now and hope to have them on line soon.
I don't believe a small "conflict" like this is going to discourage my participation in this forum.
One on my life's pleasures is to help people and I feel that this post just might do that.
As I stated, Something may have been changed, done away with, or modified to my B2320.
If I live to be 90 I stand to be corrected--I learn something new almost every day

I am glad you will be staying around as I have really learned a lot from the knowledgeable people here.

I retired three years ago after 32 years on the job and to the day I left, I was committed to improving my performance and knowledge base.

I learn something new here all the time.

Posting pictures is fairly easy once you get it to the right size.

 

[Giles]

Here is my attempt to post pictures of my B2320 Lift Control---Hope it works--if not will try again.
I have more if needed

 

[wdchyd]

Please-Please-Please.....Keep it going....Being a Greenhorn to this Tractor/lifter/digger stuff is very informative....

I have the same B2320 and today was first time using 3PH with new Box Blade behind it.....QIV was not even in my vocabulary till now.....Something else to sit back, read and learn....:thumbsup:

 

[Evil the Weasel]

That is QI. If it were position control there would be numbers on the side. That's the same control I have and I have QI.

 

[Giles]

Here are a few more--

 

[Giles]

That is QI. If it were position control there would be numbers on the side. That's the same control I have and I have QI.

The B2320DTN-1(narrow) has position control. The scale for the DTN lift, is numbered where mine only has arrows and two adjustable stops

Yes---Thats what I stated in my OP

 

[buckeyefarmer]

I learned a new one with this. I've never seen or heard of QI before, always had position control.

 

[BrierPatch]

I have to admit I am a little perplexed at this point. In Giles pictures, particularly the one that shows the linkages. It looks to be the same as mine which is QI. For position control there has to be some sort of feedback from the 3pt arms to the control valve and I can't seem to find it in the picture. I see the upper and lower limit stops, but no hard linkage going back to the control valve.

My question now is to Giles, exactly how does you 3pt work for position control. If you pull your 3pt lift lever 1/2 of the way to raise does the 3pt arms only move 1/2 up and then stop or do they continue to raise all the way?

I just went to the shop and operated the lift.
When I pull the lift leaver HALF WAY UP, the lift starts raising very slowely and continuous--moving the leaver just a small bit further causes the lift to raise rapidly.
If I have the tractor idling and the lift arms lowered to maximum I can quickly move the leaver up to the stop, and the lift will raise completely in less then 3 seconds.
As you can see from the photos, moving my lift leaver to me or away from me makes no difference.
The difference I have noticed in this Kubota, from other tractors I have owned, is that after the emplement is raised to the desired position, the lift leaver returns to neutral position. On all other tractors I have had experience with, the leaver stays in that position and moving it down results in the empliment lowering. Mine will lower only when the leaver is pushed down past the neutral position.
Is it possible that this tractor is supposed to have QI and it is not working
What has me confused is that I have read that pulling the leaver toward you and moving it will result in 1/4" of lift.
Am I assuming wrong?

 

[wdchyd]

When it is set properly you should be able to give the lever a quick 'bump' against the inner stops and it will only move a 1/4" at the lower link end. Also you can hold it against the inner stops and it will move slowly, or hold it against the outer portion of the stops and it will move quickly.

I think the "Bump" against the inner stops is the key here.....I just read the manual with my B2320 and they mention the inner stops as just "Slow Up" and "Slow Down" when held in place.....

So what I figure is the "Bump" momentarily is the 1/4" approx movement spoken of.....Yes/No?

 

[Giles]

Since I know nothing about the history of this Tractor, and the dealer did all service in the 100 hours, I will call him tomarrow and see if he will give me contact information of the original owner. If I make contact I plan to ask original owner if anything was done to the tractor lift system.
As I have stated--I have no problem with the operation of this machine--Just curious:thumbsup:

 

[wdchyd]

Thanx for bringing up this discussion as it has helped me out

What you describe here and according to what I can see in your pictures you have the QI (quarter inching) valve. Also what you describe about your old tractors is what is called position control. What is meant when we say move the handle towards you or away from you is to merly go around one set of stops to the other when you have the handle in the raise or lower position, it is not another hydrualic function of the handle. Fast and slow speed is the best way to describe it. The quarter inching part comes from setting the slow speed postion of the stops so that a bump or tap or quick (approximately 1 second) movement to the stop and back to neutral position will produce 1/4" movement in the 3pt arms or implement. See my picture on the 1st page of this thread and you can see where I labled the 2 stops. Depending on how your 3pt handle is on your tractor you may have to pull in towards you to make it hit the slow/QI stops or like mine I have to push out away from me to make it hit the fast stops. Looking at your pictures it looks like you may have to pull towards you to make your handle hit the slow/QI stops.

It looks like nothing has been done to your tractor and it looks like it is factory original, and unfortunately looks like it is QI (quarter inching).

I still wonder what would be involved with converting a QI to position control. Maybe we should start a thread about that and see if anyone has done it?

Let us know if you need more help setting up the 3pt control.
