Typically the small square bales are about 65-70 lbs and the average round bale is 1200-1300. We put up close to 20000 small squares this year and about 200 big rounds. So with those numbers I would say 17-20 small squares to a round.It really all depends on what your tension is set at for the small squares and what your height is set at for the rounds. In our area there are 3 main suppliers of hay, Bar None Ranches, Valley Hay Sales and Us. We all run pretty much the same tension and size so when people are comparing prices it is apples to apples.
Guido you must be referring to the large square bales I believe sonny was referring to the small square bales.
No doubt that everyone was thinking small.I like to think big.
