Buying Advice Quarter-inching Valve

[Giles]

As some of you are aware, I just purchased a 2009 Kubota B2320.
I have read all post concerning QI operation and I viewed the video.
I am not new to farm tractors--owned many over my fourty years of operation. However QI valve is a first for me.
With all this being said---My B2320 operates basically the same as all my other tractors. I can barely move the lift lever or raise it fast and the lift will start raising and will travel all the way to top. Lowering is the same.
Am I missing something or do I have a "rare breed"?

Giles, I find your post interesting. My B2620 will do that at lower RPM's, say under 1500, or so, but I can't get it to do that at PTO rpm when I am using my rotary cutter, etc. I get by since I do much of my box blading, etc. at 1800, or so Rpm, but other times it is pretty quick, and can vouch for it making the tractor jump a bit at full pto rpm with my 4' rotary cutter on the back, or my rear snowblower, etc. At full pto rpm, bumping my control lever will bring the implement up a foot, or more usually.

I do not have a tiller, so can't comment on it. I do not find the 1/4" valve on the 3 pt. hitch to be that much of an issue with the box blade or rear blade. I adjust what they are doing more with the top link which controls how agressive they are digging in. I do find it an annoyance with the rotary mower. You can certainly use it, but as you mow, it will tend to sag down, so you have to bump it up every once in awhile. Not a huge issue, but enough to annoy me. I will probably look at adding some type of chain system to limit the drop.

To get a position control on a Kubota, you have to go to the B2630 or an L.

According to my B2920 manual, there is a model B2320 DTN that has a position control valve.

What disappoints me the most about Kubota's lineup is that there appears not to be a tractor that has both a floating MMM and position control.

When I use my sub-soiler to rip the dense clay that I have, the tooth is constantly pulled too deep and the tractor bogs down. I have to stop about every two feet, back up a couple of inches, lift the 3ph and start again. I like the floating MMM on the BX, yet no BX has position control. If I could afford it, I would like to trade up to a B. The thing is, if I am reading everything correctly on Build My Kubota, tractors like the B2620 and B2920 offer a floating MMM, but not position control, while the B2630, B3030, B3200, and B3300 seem to be the opposite: they have position control, but no floating MMM available. In the L series, those that offer an MMM are all ground contact, i.e. no floating MMMs available.

This issue (other than the money) is the main thing that has kept me from even considering trading up to a B. I just can't justify so much money for a bigger tractor when I have to chose between position control or a floating MMM. It seems like a choice one should not have to make. There ought to be a tractor that has both. That is the only way I would start thinking about how to save up the money, as well as start figuring how I'd talk my wife into agreeing to spend it on that.

Messick, Barlow, and other dealers who visit here: PLEASE tell Kubota there needs to be a B or L series tractor on which one may choose options for BOTH position control AND a floating MMM.

I agree. There are other color tractors out there that have both now in that size range, but Kubota does seem so secure in their position that they still feel they can move you up to a more expensive unit to get the things you want. The older B2410 did have position control, but I heard that it was never a good seller. There is reasoning behind this from a manufacturer's standpoint, and I have experience working where the company was changing over to "The Toyota Principle" or "lean manufacturing", but it's best not to get me going on that one!

That's the thing, even in the more expensive Kubota models, you STILL can't get both position control and a floating MMM. I surely do not want to buy two tractors just to have both, though if I could afford an F series for mowing and an L or M for ground engagement (with position control) I would do that. But that's only in my dreams.

I know it's hard to imagine, but some of us B owners (me for one) have no use at all for position control.

 

[SPYDERLK]

:laughing: ... you must use your tractor in strange and mysterious ways.

 

[Evil the Weasel]

Front snowblower, mowing, loader work, subsoiler, middle buster, dragging logs, and towing a lawn sweeper. I don't own a single PTO driven 3pt implement yet, but maybe one of these days...

 

[Tom_H]

...subsoiler, middle buster...

I am guessing you must have sandy loam soil because my subsoiler submarines (or technically subterraines) very quickly under the resistance of dense clay. A soil with little resistance would not induce such a reaction, however position control would be an immense help to my subsoiler in clay.

I almost am tempted to fabricate a set of adjustable depth gauge wheels for the implement. Does anyone know of a subsoiler with depth gauge wheels or some other plow that already comes with depth gauge wheels that could be modified to accept one ripper shank? If I could use such a device for ripping, I could upgrade to a B2920, which is the biggest Kubota to have a floating MMM, and use this alternative to position control. I wonder, how many of you guys use ground engagement attachments with gauge wheels and thus have no need for position control?
