FEL slowly goes down.

I think the real reason is that they saved about $.04 by using a cheaper seal.
They could save the entire cost of the loader seal by eliminating it entirely and the cylinder would still not leak down. The cylinder piston seal has nothing to do with the loader arms dropping.

Drop is normal. Next time, put jack stands underneath for safety, just as you would when jacking up and working under a car.
Always park the tractor with the FEL on the ground. If you have a BH, put the locking pins in to keep the boom from sagging.
Stay safe, my friend.

Hey all, ive got a 2019 BX23s with hydraulic leakdown issues. The stablizer arms slowly lower over time. I have to park in a tight space, but every time i operate this machine, i must remember to raise the stabilizers, otherwise ill clip the wall beside it. It has been this way since purchased new, but the responses i had found in the blogosphere led me to believe it was normal. HOWEVER, i have since purchase a neglected and abused 40+ year old JD that i can raise the 3 pt with bush hog attached. Walk away for days at a time and absolutely no visible setting. What is the difference? A lot of weight on an old beat up machine at an awkward cantilevered angle vs very little weight on a new and pampered machine with the minimal load going almost straight down onto the pins, thus not really stressing the cylinder hydraulics. Can someone give a reasonable explanation as to why this would be an acceptable design if it is correct? Thanks.
If... stabilizer sag is a issue, use a ratchet strap between the two. Not a lot of force is generated by them wanting to fall, so a small one will be fine. Being the strap will be in the way when trying to mount the BH, you do not have to worry about forgetting it is on. I do the strap on my BH when the BH is off the tractor.

I understand that idea, but a "perfect" seal will slow the drop caused by a leaking valve.

Oil needs to go in or out of that cylinder in order for it to go down. That oil needs to get to a leaking valve, it can get there by way of bypassing the piston.
DCV leakage oil exits the cylinder via the ports at either end of the cylinder. The piston seal, which is in the middle of the cylinder, can do nothing to prevent or even slow down the reverse flow of oil out those ports. And BTW - o-ring seals are damn near perfect. That's why POCVs work so well at eliminating cylinder drift due to spool leakage.

This guy makes nice product. Kind of expensive but nice.
