I’ve got a 2004 6920s with tls, I recently got the accumulators regassed to the pressure stamped on them because I noticed it slam down on axle a lot when I’d drop the plough. Now that I’ve had that done it’s become very uncomfortable to drive without either the loader or weight block on the front, it used to be very comfortable with no weight, not it just hops down the road. I’ve had them rechecked since and the front two are still perfect but the third one was down a bit which apparently shouldn’t affect it much but it got topped up anyway, when I refitted them it was just as hard. Is it possible that there’s something wrong in the valve or is the 40bar that’s stamped on the accumulators just too much pressure? The level sensor seems to be fine because it always finds the right height when I start driving. I’ve opened the pipe going to the third accumulator a few times after driving it and there’s not much pressure behind it.

Too much pressure. Speak to your dealer they will supply you correct spec
That’s sounds like an expensive problem, luckily mines holding at the one height perfectly but thanks anyway.
I’ve a new theory as to what my issue is. I’ve spoke to a mechanic and been told the accumulator pressure is correct. I’ve noticed that that tractor is not pressuring the circuit for the third accumulator and when I jack up the front with the loader or lift arms and stop and start the tractor it no longer lifts the axle up. I’m most of the way into taking out the valve, does anyone know what component of the valve pressurises that circuit? I’ve checked both solenoids and they work and are getting pressure but I don’t think they control that other circuit anyway. Thanks in advance
