I just bought the book, "Turn Hard Soil into Cold Cash" by Robin Pedrotti. The question is...... Is this field still viable? Since the book was written in 1992, is it too outdated, in terms of the business potential? If NOT, then is it worth the time to pursue only this type of business, instead of the mowing end? And, what about with a tractor? I have a B7510 Kubota tractor, with a Front End Loader, and all the trimmings, from post hole digger, to finish mower, and I planned on providing services with that, but if the aeration business is great enough in demand, I might go to doing that instead, or as an addition. Comments please!
