I have a 2007 M9540 (no front end loader). My 3-point stopped lifting under load. With nothing on it, it lifts fine, but as soon as I put a brush hog on, it will try to lift but can’t. Could this be as simple as dirty hydraulic filters, or is this a common mechanical issue?

Ir could be any number of things. Rather than guess diagnose..
Do your rear remotes work?
Do you have it in draft control mode?

I believe the rear remotes work, but to be honest I don’t know. I purchased the tractor used a few years ago, and I don’t have any hydraulic implements. I ordered a gauge to check hydraulic pressure, so I’ll be able to check that when it arrives.
Regarding the draft control - I will check and get back, but I’ve tried it in every position and it still wouldn’t lift heavy implements.
it moves up/down just fine with nothing attached.
It will lift my box blade fine, but drops when the tractor is at idle or off (regardless of lever position)
It will try to lift the brush hog, but doesn’t have enough power to fully lift it - maybe a couple inches. With the brush hog barely off the ground, and the rear wheel supporting the back of the hog, I’ll drive out to the field (a few hundred yards). By the time I get out there, sometimes the the brush hog has lifted. Once I drop it to begin mowing, we’re right back to square one (doesn’t want to lift).
Thats mich better. What you are describing sounds like the 3pt lift cylinder(s) are leaking. The safety relief is another possibility. When you get your gauge check pressure at the remotes and that will guide where to go next.
