I haven't gotten to checking the hydraulic pressure at the rear yet. We had a decent snow, so I was using the tractor to clear the driveway with the 3pt scraper blade. I've been setting the 3pt lever to lift then hopping off to help raise the scraper blade. At one point I heard what sounded like...

The 3pt safety valve is near the lowering speed adjuster knob under the seat.

I've been looking over the Manual and looking at the tractor. I'm still unsure of a good way to check the hydraulic pressure at the back of the tractor. Also, I doubt it's the cylinder seals, as it will stay up with weight on it (didn't drift down since last weekend). I do have a question...

Per the image below, it looks the port on the front is a Tank port.

The tractor does not have draft control. Is there a good place to check the pressure at the rear?

I finally got a gauge and the fittings together and had some time to look at the tractor again. I'm seeing 2200/2300 psi coming from the power-beyond hose off the loader valve (I disconnected the PB between the loader valve and the hydraulic block and put my gauge on a spare quick coupler). So...

I played with the decent adjustment, its set toward the slower end, but not closed off. Having a gauge isn't a bad idea anyway (and I don't mind an excuse to get more tools), and now I can find out what the pressure is and if I need to shim the relief valve.

I ordered a hydraulic pressure gauge, going to be a few days before it gets here.

Despite the heavy layer of rust protection (oily grime), that's the selector I moved. When up (turned clockwise), the FEL doesn't work, and the 3 point shows the same symptoms (moves slow & won't lift any weight), when down (counter clockwise), the FEL works.

I meant the block outlet that feeds the hard line that goes back to the 3 point, but I can do the same thing with the Power Beyond line coming back to the block.

Loader is a Kubota BF400G, loader valve has 7 hoses, 3 connect to the block. Unfortunately, I don't have a suitable gauge to check the hydraulic pressure, but I can disconnect lines and check for flow. I can see how much flow comes out of the hard line that feeds 3 pt off the block.

I don't have rear remotes, or anything additional tied to the hydraulics (beyond the FEL). I did check and adjust the feedback lever / position control rod already. That seems to work as I can limit/adjust the max lift height (with no weight on the arms).

It only has the 1 lever, so I'm assuming no draft control. I also played with the lowering speed knob, that does what it's supposed to, but didn't help with the arms not lifting.

My L2550 3 point hitch doesn't want to lift any weight. It will go up (slowly) to full height with no weight on it. With weight (my scraper blade) it only goes up a couple inches, if i lift the scraper blade manually, it'll hold in place (and stay in place if I stand on it). Let it sit overnight...

This got me thinking. I pushed the brakes in and set the lock, the slight tire movement / wiggle didn't change (seems like this is brake issue). I released the brakes and put a clamp on the pedals to hold them all the way up, still no change, got a strap and drug the tractor (in neutral), the...
