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
My neighbor baled his irrigated alfalfa 3-twine, 100-120 lb bales. His customers complained about the weight so he changed to 2-twine 45-55 lb bales. Even then he was losing money what with the cost of consumables (irrigation water, fuel, fertilizer, etc). So he ripped his fields last fall, leveled them and planted a plum tree orchard for prunes (aka dried plums) last month. Sunsweet pays better than the alfalfa buyers.
If 3 twine balers are used around here, they must be well hidden because I've never seen one. I knew there had to be at least one in California because, I've seen the bales on TV.




I do that manually when I finish baling a cutting and want to clean out the baler. Perhaps I should do that for the last 2 bales to make the easier to get out...Oh gotcha. When I was working on this baler frying to get it to tie a k.ot I set it to about 15 inch lengths the kids loved that!
I never seen an aftermarket sq baler drive system such as in your photo.

Those things are all over the place around here.
