a few years ago I built a baler such as is seen on youtube , a.k.a. "pine straw baler" , the vertical one with manually compressed leverage. It works just fine for baling my grass clippings. I wanted to eliminate the series of manually compressing , so I made up a horizontal baler powered by compressed air.
I used an air cylinder with a 2 inch bore, 24 inch stroke, 5/8 dia rod. I fill my 30 gal. air compressor to 120 p.s.i. and trailer the baler and compressor to the "hay" pile.
I can make up about 16 bales before the compressor drops to about 60 p.s.i. then if I am not done yet I travel it back to an outlet and recharge the compressor. By then I am ready for a break from the routine anyway. this one is sized about the same as my vertical manual one, bales are about 12" x 17" x 24 " . the difference here though is that the front "door" and also the rear wall , are slotted. I could have made it to eject the bale out the end as the next one is forming, but chose to do it this way , making one bale at a time. I can easily push the loading section into the bale section by hand, after a few armloads I simply fill the loading section for the last time and then give it one stroke of compression.
