I grow about 10 acres of hay. It is not profitable. The only reason I do it, is to keep the land in ag use and tax basis. Between chemicals, fertilizer, seed, fuel and equipment any cash I make is thrown back on the land. I do get hay for my horses. The equipment is 70's vintage I use a 40 PTO hp tractor on a NH 477 haybine and a NH 310 baler. It's enough tractor to pull a wagon behind the baler. A discbine may be too much for 40 hp.
Hay making is all about timing and weather. The hardest part for me is labor to pick up the small bales. Even paying a premium, the work is hard, hot and dusty.
How will you handle and store the bales ?
Not trying to make a profit but as it stands right now I spend around $4500 a year on hay. I also don't like all the run around, finding sellers, trying to get our schedules matched up, driving, loading, hauling, unloading, stacking. I'd rather just do my own hay and not deal with hay sellers. At the price I'm spending on hay it seems buying equipment like this 273 New Holland Baler with Thrower - farm & garden - by owner - sale would pay for itself. I can borrow wagons from my neighbor or eventually buy my own. I have an elevator and stack it in my barn.
