thats light for out here! our normal bales in these parts are 3 twine 90-140+ bales for alfalfa
I think I'd try making the the bales shorter. Maybe around 30".
I can't understand bailing them that heavy. It seems much more efficent to make them small enough that one man can handle them without having to pay a chiropractor.
Long bales should stack better. I suggested shortening them in hopes they'd hold together.The 36 inch works well for me for stacking. I really am not bothered by the weight I was hoping for 75 but
