Boy, that's at that tipping point, need kinda good equipment to keep up with 30 acres 3x. You won't get by with the cast off old junk.
Not so many acres you are going to make a killing on it either tho.
Is there a good grass hay market in your location? (here you compete with road ditch hay, and hard to get a lot for grass hay...)
Would be nice if you had a little bit of experience, with a 5 acre plot for a ear or 2 to get your feet wet. You ever work with hay equipment, or will it all be new to you?
