There's not even a real question here. This is essentially just a rant, but hopefully it might help someone else having the same problem know what to look for.
I've had my BX23S for about a year now, and I've had issues with the mower deck occasionally not lowering (usually after installing it), despite the height adjustment not being in the "Top" position and the 3pt hitch lowering speed at a reasonable setting (which doesn't get changed). When this happens, I have to jiggle the arm a bit to get it to lower.
The cause seems to be pretty evident in the pictures below. I don't know what this type of joint is called, but it's pretty common, and obviously meant to retain the lower arm onto the pivot pin provided by the upper arm, while also allowing the two to be separated when rotated into the right orientation. The problem is that the retainer head of the pivot pin isn't doing its job, and the lower arm is trying to "cam out"/pop off (and from the looks of it, very nearly succeeding). That retainer end should obviously be rotated as close to perpendicular to the slot in the lower arm throughout the range of motion to ensure retention (i.e. it should ideally be horizontal, like it is on the "good" side).
This seems to be a manufacturing defect to me. I intend to take these pictures to my dealer tomorrow to discuss the issue and warranty coverage, but the initial response when I explained the situation over the phone was that I pay $200 for pickup/delivery and let them see what they can find in 15-30 days (while my meadow grass is already too tall) at $145/hr plus parts.
