3rd Function Issue

[RFB]

GL540HSTC with 3rd function FEL hydraulics for grapple and snow blade angle control.

When pushing the buttons to activate flow in one direction or the other, the circuits do not cancel when the button is released. I have to flip back and forth (top and bottom button on joystick) until the solenoid releases. This happens in both directions.

It seems to become less prevalent after about 30-45 minutes of use (fluid getting warmer??)

Any ideas gentlemen?

Welcome to the third function Kubota club.Sadly not a good thing.Lots of problems with this.No good fix;the only thing that works for me,slightly drop the three point hitch.Mine has been to the dealers three times for the same thing,called Kubota corp.Kubota has a desigh flaw,I believe.

It has been the subject of many complaints. The valve pressures up and the return spring is not strong enough to center the valve.
After reading all the complaints I T' d into a rear remote and used the loader hardware from a third function kit to route the lines to the front. I can't use the rear remote and third function at the same time but adding a second and third RR is cheaper and more satisfactory than the sticky electric valve.

Thank you gentlemen.

I was unaware of the history re. this issue. I have emailed my dealer (tractor is just a few months old) and also linked to the various posts here. He is pretty attentive to the site to obtain knowledge from users.

I also asked him to research the issue prior to any service scheduling. I will post an update when I know more.

That is bad news I just installed the kit on a B26. I will be interested to hear what you learn.

Just curious, what does this lovely package cost, and how much fun is it to install?

The problem seems to only show up when the 3pt is out of adjustment and is at top and dead heading or hitting releaf instead neutral. You should always have a little play see shop manual but 1/2-3/4" of travel left when the lever is at the top.
I had my for 3 years no issues on B26 but had friend that had problems and the problems left after I adjust 3pt.
Local dealler said problem shows up when tractor not set up correctly.
Mine was included in price but I installed it about 1hr to install.

Harry,

I added as a oem option with the purchase so I am unsure of the price. If you go to Kubota (build you tractor), it might have the msrp price there.


Powerstroke,

What adjustments do you suggest for the 3 point?



I will keep the thread updated as I know more.

I'm on my second Grand L with Kubota's 3rd valve and both of them reacted the same way in which they worked every time I used them but once in awhile there might be a small (less than a second) delay in kicking out. It's barey noticeable , has no effect on its operation and not even a concern to me.
It will be interesting to see what your dealer says. I'm actually very pleased with mine.

There is adjustment to center the 3pt valve its a threaded rod that is attached to rocker shaft with to jam nuts. If you raise 3pt lever all the way some you should be able to grab 3pt with nothing on it and have just a little play left on top of travel. Also some people remove the adjuster that is on lever hole which allows lever to travel to far. Most of time I can here it if is out of adjust do to it making relief squil.
