I used an 18 hp Yanmar 4wd tractor for baling my own hay here in Michigan. First used a pto sickle bar then graduated to a NH479 mow/conditioner. Raked with a NH 5 bar, baled with a JD 14T. Lack of live power on the Yanmar was a minor problem. Switched to a JD1070 4wd (38 hp), still run the 479. Switched to a Kuhn tedder/rake because of drying time and rain issues. Still use the 14T. Now have a NH staker wagon to pick them up. This ability allowed me to make money selling hay to the neighbors and trade hay discount for help loading into the barn. I do all the work by myself now. Friends still prefer my baled weeds to the stronger hay available at the Co-op. Looks good on the Accountant's side and on property taxes (still agricultural). I do about 20 - 25 acres per year, splitting the fields up into sections based on rain forecast. Most folks are in too big a hurry and don't know the mechanisms involved in cutting, raking, baling and picking up hay. Great chance to learn. Most of my customers are female and they appreciate 40-45 lb bales instead of the 75 - 100 lb bales found elsewhere. Its a lifting thing. I get $2.50 a bale out of the field and $3.50 delivered. Its a great chance to learn about bearings, lubrication, welding, organization, patience and rewards.
