No where near 60 lbs - Wife wouldn't be able to handle in the barn. More like 40 I guess. I was baling with an old Ford 250 PTO baler and an 8N. Was a struggle with heavy windrows, and the baler didn't like heavy bales. Wouldn't miss a single knot in 500 or 600 bales if I kept it set like that. The bales were pretty dense, just shorter, and stayed together OK.
I think I managed to attach a pic of my bale loader with a regular flat bed JD hay wagon (1942) and our '44A. Couldn't find one with a wagon with sides.
