Neighbor has a grass pasture near me, 0 cows and stopped renting it out. Don’t know why but grass looks heavy, thought about asking if I could bale for grass hay.  I have all my own equipment, be hard to do on per acre basis.  Would be 3-5 acre patches, I’m guessing cause it has steep areas couldn’t do.  Thought about offering landowner money per bale I get off it. I have a 5 x6 round baler.  
Any ideas on how much to offer?
