Backhoe Backhoe Issue

[RFB]

Here is a copy of an email that I just sent to Rhino:

"Sirs,

In 2006 I purchased (by special order since my tractor dealer was unaware of your product) a Rhino 85 backhoe and subframe mount for my Kubota L5030. It has proven to be an excellent tool except for one nagging issue. The stabilizers continually lose pressure and need to be readjusted (adding more down pressure) every couple of minutes. This is my first backhoe, and at first I thought that was normal so I never addressed it. Recently I spoke with another owner of a Rhino 85 on a webiste that I frequent (it is a site dedicated to tractors and attachments called Tractorbynet.com) and he mentioned that he has had the same problem since he purchased his.

What is the cause of this issue, and is there a remedy for it?

Thank you,"

Is the above described behavior of the backhoe stabilizers a normal phenomenon? I will post their reply if I receive one from Rhino.

No, leakdown like that is not common and should not be accepted. It will be intersting to hear/see their response.

Its not normal- perhaps its a valveor internal leaking seals on cylinder. issue on the rhino. Sorry to hear that though- you shouldn't have to put up with that.

Unless you are dragging the tractor and digging in the stabilizers so they require readjustment as they sink into the soil, then you have a leakdown problem that, as others noted, is not within the expected range of operation. If you saw leakdown overnight that would be normal but not if you need to readjust during an hour or two while on a solid surface.

If a FEL had a similar problem it could be fixed with a $3 "O" ring...does this happen in both stabilizers?

If that persists...then you really don't have stabilizers do you? Frustrating when things don't work the way they're supposed to.

Perhaps Rhino "cheaped out" and used spool valves without load checks
for the outriggers. It seems unlikely that both outrigger cylinders would
have leaky piston seals when new.

I can tell you that my Bulgarian hoes take hours to leak down, and my
Kubota hoe with 2400hrs on it had good outrigger performance, too.

One TBN member here went so far as to install pilot-operated check
valves on his outriggers to fix the same issue you have.

Well, here is Rhino's first reply so far:

"During operation the stabilizers should not hold up the rear of the tractor when using backhoe. This is explained in the operators... Lower stabilizers until weight of tractor is supported by stabilizers. Do not lift tractor tires off ground. If you have any other questions please feel free to contact us."

I immediately wrote back and told them that is not how I operate it (by jacking it up in the air), and that they lost pressure from day one. No return reply so far.
