Bought a 2020 bx2380 new a month ago. Read online a great deal about hydraulic pressure specs and how to check with a gauge and shim for more pressure to get a little more lift out of FEL. Bought the Bxpanded kit (gauge and shims) expecting factory settings to be very conservative as so many people have reported. Heated up the tractor tonight to check factory settings on the pressure before taking off the pressure relief valve to shim for more oomph. Was extremely surprised to find the factory settings at 2350psi. Checked all four valves and got same reading. Specs recommend between 1790psi and 1850psi. Do I have a bad gauge or is my hydraulic system pressure set by the factory incorrect? Do not want to blow pumps, hoses or seals, but it seems odd that the factory would make a mistake with this. Would appreciate your wise advice.

2350 psi is a bit high! I would hopefully expect a bad gauge but then again most of them are spot on.
Mine was right at 1750 ish and I bumped it up to 2000 psi ish. It was a great improvement too. At 2350 I do not think I would want to mess with it until I go another reading with another gauge perhaps.
If your dealer is near by - ask them to "check it" and see what they come up with.... just a thought.

The FIRST thing to do is have the calibration checked on your gauges. (It’d be kinda silly to condemn a brand new, expensive, under-warranty tractor because a cheap gauge that had no pedigree read wrong.)

The SECOND thing to do is have your dealer confirm the issue.

THEN proceed to arrive at a conclusion.

Be happy. Don’t worry. If it is a problem... that’s why you have a warranty.

(Still need to worry about something? How are you going to feel when the dealer reduces the pressure to the factory specs and then you find you cannot lift what you need with your tractor?) :devilish:

Maybe someone returned a “new” BX2380 and had shims already installed? Then because of the low hours they could sell it to you “new”. Try seeing if shims are already installed.

BXpanded sent me another pressure gauge to see if I get the same reading. Will check it tonight and hope the first gauge was defective. I am thinking that if I get the same result and since it is under warranty, I should call Kubota about it. If it wasn't under warranty, I would probably check to see if removing a factory installed shim solves the problem. If 2350psi is accurate, it seems like it would be the proverbial ticking bomb since that is 500psi over specs.

Hoping that's not the case. Will be checking pressure with a new gauge and either calling Kubota or removing shims to bring it down to 2000psi.
