I have a BX2370 and I believe all the BXs have the same 3 point control with the 1/4" capability. I have not specifically tested my 3 point for seeping down over time, but I have never noticed it seeping down either. My 3 point implements include a 250# rear blade and a 430# grading scraper. You didn't say how much weight you had on your 3 point when you tested it.

I had my BX out today so I hung the grading scraper on the 3 point. I guess I have never left anything hanging for more than a few minutes, because I was surprised to find my 3 point drops at about the same rate as yours when loaded with the 427# grading scraper.

Some leakage/drop on the 3PH is normal when the tractor is off, especially if holding big weight. My little BX will make a "creak" sound now and then as it lowers the mower deck if I don't drop it down when parked. It's good practice to relax those mechanisms when not running.

However, I don't know what you mean by "seeps down a little," but it should hold when running, unless you're fiddling with the control arm.

Understand a little "wiggle" up-and-down might happen just as the machine is running. An 1/8 or 1/4" variation might not be an issue. There is fluid moving in many directions to move many different parts of the machine during operation.

If a 3PH attachment is constantly dropping down while running the machine - at 31 hours, the dealer needs to look at it, lest you have to deal with the issue later.

JMHO, and best of luck!

My B2620 3pth will bleed down when I leave it parked and not running. Don't know what the rate of decent is, but I do notice it when I leave it say parked in the barn overnight.

In 1992 I purchased a b7100 with an fel. The bucket would bleed down slowly. I thought maybe it was normal. As the years went by the rate of bleed down increased. Today the bleed down rate is in the seconds. I say, get it to the dealer to be checked out before the warranty is up.

Nature of the system, I have to bump mine up from time to time, there are a lot of threads on another site about this. Some add check chains to maintain a consistent mowing height with a rotary cutter. I believe the new B2601 has position control 3PH.

We have two BXs and just bought a John Deere 1025R with position control, of course it is more expensive to produce than quarter inching.

These issues are very hard to diagnose. What is happening is that the cylinder is filled with oil when the lift is up. When sitting, the oil is leaking. Need to find out where the leak is, and therein lies the problem. The cylinder is internal, under the top cover kind of inside the transmission. Because it's inside, you cannot see where it's leaking from. Could be from the valve, the drop speed control or the cylinder itself...or between the valve and the cylinder (o-rings), the seals on the piston, the seals on the drop speed control. So there are a lot of places oil can leak past.

The dealer is helping you, or trying to anyway. I've not personally heard of these having big leakage problems, so that points to Kubota's RSR having to perform "exploratory surgery"...meaning, they're going to have to take it apart, replace stuff, reassemble and try it. On a B-20 series, you're looking at 4-7 hours each time and that's working pretty fast.

So you want a new one. That's a tough call, and Kubota's customer service is the only way you'll get anything done in that department. The B2620 is no longer made, so you'd have to get into a B2601 which replaces the 2620. It's also more expensive, so if Kubota were to give you a new one, you would be out the price difference at a minimum. The 2620 and 2320 were proven tractors, and honestly, knowing what I know of the 2601 and 2301, Keep what you have and get it fixed. Just my thoughts on that issue, for what it's worth. Keep in mind that when it comes to "major units" (tractors, RTV's, 4 wheelers, the big stuff), dealer's aren't like Wal-Mart in that if you don't like what you have, don't expect a refund or no hassle exchange. If that's what you want, you're going to have to work for it.

Also keep in mind that Kubota has a drop rate specification..I dont know what it is, but on loaders, 2" per hour is the accepted rate. More, and there's a leak. Less and they aren't going to spend much time trying to fix it. I'm sure the 3 point also has a specification, I just don't know what the actual rate is, whether it be 6" per hour or .5" per hour.

I find it odd, dealer had it first go round and it held. Now it doesent. They use lock valve?
As mentioned there are lots of parts in 3 pt. hard to find leaks.

If that info is correct, there are multiple problems with hundreds of possibilities. The 3 point stuff is pretty simple to anyone who's been into them before, just time consuming to find it. I am questioning why they didn't use the lock valve? That is number one thing to do in a leak-down situation...shut the lock valve off..no leak=valve problem. Still leak=every other possibility except the lock valve. Lock valve is easy to get to and fix.

I have a suspicion, but I will not go into detail. I want to know what the problem is/was and how it was addressed.

Keep us updated.

Nothing unusual about a tractor with a quarter inching 3PH to leak down, it has been that way on both our Kubotas. The replacement 2601 has a position control 3PH.

Mines done this since hour #1. It's normal. Mine will make a little clunk noise every 10 min or so as it drops a mm at a time. I'd be very surprised if your dealer was able to get it to hold for two days but if they did you have a very good dealer!

I got lucky with my B2620. My 3 pt never seeps down, nor does my steering wheel position ever change. (another complaint I've heard of.)
Around 260 hours so far.
