Spool broke in Kubota B2920 loader valve - any options besides new $900 loader valve?

I think you made the right choice. Keep it original, good choice.

I dropped the B2920 at the dealer and signed a work order to fix / replace valve, and change the transmission fluid / filters.

I am mechanically inclined but even the dealer quotes 3-5 hours of labor to R&R the valve, in a shop that has all appropriate equipment, tools, manuals, and training to do so. I laid under the tractor and decided there is a considerable amount to remove to be able to access the valve to remove it. My valve spools are two piece; the lowest detent portion is threaded on to the main spool. I spoke to the service manager about this and if it is repairable they will replace just the threaded piece.

I thought about the aftermarket valves, and it was fairly easy to conclude I wouldn't go this way. I have access to welding and cutting equipment, but basically it came down to three reasons:

1.) Adapting an aftermarket valve is not simple given the location of the factory valve
2.) This tractor is a 2013 still in nice condition - don't want the aftermarket look
3.) Kubota loader valves are very nice in their ability to dump/curl while raising/lowering. Most other valves are not as good.

In the end, I appreciate the support and advice. I'm figuring this could cost me between $1500-2000 with the fluid change as well, but the tractor should be good after that.

Sometimes you just have to bite the bullet. Frankly after looking at the aternatives I'd probably do the same.

But one thing I would like to know is more about why the original one failed because it is such an unusual kind of failure.
In fact, if something like that happened to mine I'd at least want some technical explanation or maybe a sit-down chat whoever is in charge the USA technical service dept. for Kubota.....

I'm guessing here, but wouldn't it make sense for the dealer to help set that up?? After all, it's his brand's reputation that's at stake. A worn-out pump might be due to anything, but a broken spool internal to a valve?? Comeonnow..... I doubt break it like that with a hammer.
Or am I asking too much?

When my Kubota's hydraulic cylinder failed out of warranty, it was also the kind of failure that could not reasonably be caused by use or abuse. Which meant that it obviously had to be some kind of problem in the original manufacture.

I didn't even have to argue, in fact it was my dealer who pointed out the facts. And he contacted Kubota's tech rep who took care of it all for no charge....
