Hello all-

My Dad has a Kubota B3030, about 8 years old. Used for lots of things including snow clearing with front mount OE Kubota snowblower.

Recently the main steel hydraulic line off the engine developed a crack/ severe leak; machine went into dealer, and they needed to take lots apart, even removing the cab, in order to replace the hydraulic line. ouch...$$$...

My dad has been sick so I ended up doing snow clearing with it; have used it with the snowblower before but not in several years.

What's puzzling me is that as it came back from the dealer, I could not get the snowblower to "drop and float" - it would drop but remain rigid, which equals fixed height and either having to run it elevated from the ground or no steering if pushed down against the ground. Moved the hoses and couplings around and was able to get it to "float" when hooked up so that hydraulic control joystick raises/ lowers the blower when you move the joystick left/ right (right= down/ float detent). Then had to use the front/ back of the joystick to run the rotator on the snowblower's chute.

There seems to be no float detent available on the front/ back movement of the joystick.

This is klutzy as hell. I am used to equipment where front/ back on the joystick raises a main assembly up/ down and the side-side on the joystick controls the auxiliary motion, such as a bucket or snowblower chute.

Am I right that something is out of whack?

I cannot say for sure if this was this way before the recent trip to the dealer.

Can someone confirm for me that there should be a float detent in the front/ back on the OE Kubota joystick, not on the side-side motion of the joystick.

If this is something where they got the cabling bassackwards, is it something I can swap the cables on without major headache/ heartburn? Any tips on what to change and how? I've worked on various other hydraulics but never on this machine.

It should not be a big deal swapping the hoses around to get the up/down/float valve connected to the correct set of hoses, as well as the chute rotation. Make sure the blower is down on the ground, and the tractor is off. Then move the valve lever around to make sure there is no trapped pressure. Mark the hoses so you keep the proper pairs. Then your biggest worry will be that up is up, and right is right.
Have some rags handy; you may lose a little bit of hydraulic fluid - but it should not be much. Just what is in the hoses if you allow them to drop down low.
This sounds like a simple dealer mistake - they do make them on occasion.
Let us know how you make out...

Thanks, but the problem isn't with moving hoses (already been there and done that). Problem is that there is no detectable float detent in the fore-aft movement of the joystick valve, whereas there is a detectable float detent if I push the joystick hard right. So it's not in the arrangement of the hoses, it's (as far as I can tell) in the way that the cables are hooked to the valve body (unless there is a detent in the fore-aft that simply isn't working right now).

It is certainly possible that they put the joystick control on the valve assembly incorrectly. I've done things that dumb before...

I called the dealer and the guy gave me a frustrating and immediately defensive/ argumentative speel that the valve wasn't operating properly when they had it in for the service, and needed rebuilding, which would require it coming into the shop again (if that was the case why didn't they check with us about fixing it when it was in the first time!?!?!)... and the recent bill for the replacement of the steel hydraulic line (which never should have failed in the first place) was a whopper, as they supposedly had to pull the cab and wheels to change the steel line

I suspected it was mis-crossed cables, but did not want to dig into the valve end of the cabling, because it is in very tight quarters with the cab and loader frame... and didn't know if I'd need specialized tools or a manual...but decided to carefully disassemble the housing where the cables go into the joystick.

Found that the two cable ends in the joystick housing were identical, and traded them. Put it back together and now it works EXACTLY like it should and always did before.

Problem solved, which I am glad for (and I appreciate the support of all of you here), but am severely unimpressed by the dealer's handling of this. Yes, mistakes happen, but competent/ responsible businesses are willing to face them and make it right for the customer. So I'll name names: Riverside Tractor in Berlin VT, now part of Champlain Valley Equipment. Riverside used to seem pretty attentive to customers when it came to repairs, but at least based on this experience, that seems to not be the case under the new/ bigger ownership.

Glad you got it fixed and back to normal. I fully understand your feelings about the dealer. I went thru a similar situation with my local dealer.
