Buying Advice Quarter-inching Valve

This is getting interesting. Just got this email.

Dear Mr. Hoyt:

Thank you for your inquiry. Yes, we can confirm that the BX25 tractor
comes with hydraulic implement position control as standard equipment.

Best regards,
Kubota BX Team.

The B series Narrow tractors have position control and more 3 point lift capacity from what I can gather about them. Not many people seem to have experiance with the narrow models. You can adjust the back tire for a bit wider stance but I would imagine its still pretty tippy for general use.

That is a plus if true. It would have been more clear if they had noted that this was an upgrade over the quarter inching system which itself is technically a "hydraulic implement position control" system. Still, it should be easy enough to figure out if you go to see one.

Upon further inquiry, no surprises.

Dear Mr. Hoyt:

The BX25 control is the same as other BX tractors.

Best regards,

It is remarkable that the Kubota tech support people are too embarrassed to state simply that the BX uses a quarter inching valve system. Could it be that they understand it is a cynical marketing manuver to use it over the position control system in order to drive B/BX customers to larger tractors? Nah, Kubota is warm and fuzzy, they'd never do that.:ashamed:

While closing the deal at my Kubota dealer's today, and while taking my look see of the B2320, I asked whether, during setup and assembling, they adjust the stops. Looking a bit confused, he simply said, "Oh, no those are set at the factory". I pursued it no further. I suspect few dealers would see it much differently.

Draft control, position control, quarter inching valve. Real farm tractors have draft control and position control.

Use draft control for moldboard plowing, sub-soilers etc. If the implement encounters a harder area as it is being pulled through the ground, the draft control will sense this and automatically raise the implement. When the ground conditions become softer the draft control will automatically lower the implement. Draft control is a internal mechanical system designed to maintain a steady pull i.e. "Draft" on the tractor.

Position control allows the operator to select the implement height regardless of the amount pull on the tractor.

Most modern compact tractors do not have draft control, because this saves
manufacturing costs. If a person was trying to plow a field and knew what draft control did, they would wish they had draft control. It makes moldboard plowing fun.

Quarter inching valve. This is obviously built into the machines to reduce the cost per tractor. The engineer(s), marketing personnel, and bean counters responsible should be castrated.:thumbsup: That would tend to discourage cost cutting measures that make for an inferior product.

If I were selling tractors, I would use the quarter inching valve against Kubotas and any other tractor so equipped. That would fall under knowing the weak points of your competitors:thumbsup:

The 1/4 inching does work on the BX series. On my BX25 I had to adjust the stops to get it to work correctly, also you can adjust the rate of drop or by turning the knob located between the deck and seat. For it to work (when adjusted right) pull towards you and push the level up or down until it hits the stop....if it doesn't hit either stop you have to adjust, if it hit but its moving up or down to much you have to adjust......Once you get it adjusted it will be fine.

What the heck? The smaller, compacts which have quarter inch valving, are not likely to be out plowing in fields, as you described. Shoot the BX doesn't have the ground clearance for such work.

90% of the small, compacts are never going to be doing what you describe. This is mostly a straw man argument and a slap against Kubota.

Could Kubota make position control standard and raise the price? Sure. These small tractors are plenty pricey now and adding something, that not everyone will use, doesn't make much sense to me. Adding it as an option creates manufacturing and ordering more difficult.

Sooner or later, if Deere and those who do offer some kind of depth control will pressure Kubota and Kubota will respond. There are other threads here about the near future of these tractors and just how fancy the next gen is likely to be.

Respectfully;
Draft control is for plowing fields and pulling sub-soilers.

Position control is used for everything else.

The quarter inching valve is a cheap substitute for position control. Position control is the minimum standard for a usable three point hitch. And then somebody wanted to create a job and cut costs so they dreamed up the QI valve. Just because it is a new idea does not mean it is better.

My personal opinion was as follows, There are Kubota tractors, and then there is everything else. Buy a Kubota

But now; I would not buy a Kubota with a QI valve, it sounds to me like a very poor design.

If Kubota wants to keep the price down they should quit adding bling to the tractors. All those fancy plastic parts are expensive when they get broke.

Has anyone figured out why all new tractors now have curved loader arms?
It all goes back to the Cat backhoes with the curved backhoe boom. The curved boom really serves no purpose (I have used Cat backhoes). It is just a sales gimmick. Then Deere went with curved hoe booms and curved loader
booms. Now everybody has curved booms, and they still serve no purpose.
Engineers are changing things, just so they can have jobs. If you want to make a machine more powerful you turn the hydraulic pressure up.

Personally, I do not like fancy tractors. Fancy is more money, and more things to go wrong.
