I've been soaking in PB Blaster to see if I can get it loose. I think the stuck pin is bound because the opposite side is not fully seated under the bucket angle bracket, whereas the stuck pin side is fully seated.
I screwed up trying to release my bucket and now one pin is stuck and the other pin is free but the bucket is not fully seated in the angled slot. Is there a way to un-torque the bucket to release the pressure on the stuck pin?
