After the fight with a bale of hay in which it won, the kids gone down to the barn to figure out what and how it happen.
What I used was an old antiquated 4 arm grabber that are set with two levers and released by rope, the grabber is on a chain block mounted to an I-Beam, on my last bale I set the levers to the grabber and gone down the stairs, once I was in place I pulled on the chain to move the bale over the trailer, while pulling the chain I must have inadvertently pulled the rope just enough to release one set of arms (short pull) causing the bale to sling-shot towards me from a height of 20 feet (roughly) I didn't see what had happen given I only had one light on below in pitch darkness, I should have remained on the loft for my last bale. The bale grabber is a two person job with adequate lighting!
I have done this by myself for so long complacency set in, bottom line, my fault 100%
