The top mounts appear to be better. I removed and installed the pins a few times rocking the BH way back, and they now drop out like they should. Finally removed the BH for storage and installed the 3-point hitch, the Heavy Hitch, and (8) new JD 42lb weights that I worked on this week ( degrease, etch primer, commercial black paint). I could not stand putting green weights
on my orange tractor. LOL
