Bad pressure gauge?

[Harry in Ky]

Okay, I don't mind admitting when I'm wrong. Thanks for explaining that. I'm not a Branson man. Have probably only seen one or two, and certainly was never involved with the hydraulics. The brand name tends to connect and again separate from other tractor brands over the years, so it's likely there are others that operate in the same way. I just have never been involved with any.

Technically yes, if there wasn't another valve (3pt) in the circuit. So without the backhoe in the system, you have to connect the loop back together to feed the 3 pt and complete the circuit.

If you put the gauge right there in the loop, you should be able to see the pressure for the 3 pt valve. The way the 3 pt position control valve works always puts full pressure, regardless of the weight that is on the 3 pt. EDIT: When the 3 pt is being actuated.

Funny thing about this: yesterday I used the tractor to move something heavy and long, too long to use the forks and get it through gates and down a road (a very wide roll of netting we use for fruit trees vs birds). One end I put on the tiller that's on the 3ph, the other end was on a wagon, and the pipe going through the roll that supports it usually I shoved farther in so it wouldn't stick out so far.

A while later after getting the roll set up in its new location, I found the 3ph wasn't operating. All other hydraulics were fine, I'm like "ok so NOW there's suddenly an electrical thing about this?" but no on closer inspection when I knocked the pipe it hit the backhoe loop connector that keeps the two hoses together just right and while superficially the loop looked complete because of how the hose is being held there, the two ends were no longer connected...

and I thought of this post and how "without the backhoe you have to connect the loop... for the 3ph"

Bingo!

Good catch.

If the engine was idling, then you would probably noticed the load on the engine as the hydraulic pumps pushed fluid at max pressure through the relief valve. With the engine revved higher, it's probably less noticeable.

Did you end up getting the pressure gauge to work?

I haven't had the backhoe on yet; I may put it in the loop and watch it as I raise the 3ph and see if it shows it then. Will update.

Yeah, try that and give us feedback. I'm curious now if it's indeed a bad gauge or not.

When manipulating the 3ph it briefly hits about 2500, should be good.
