I have often considered doing this to supplement my income. I am old enough that I can't follow a conventional Ryan-type aerator around all day but figured I may be able to hire some young strong lads to do the heavy lifting. Or I figured something like a LA28 or a Plugr may be less brutal on the body. Any comments, thoughts? Can a person make enough to get a return on his time and investment even if it may not be enough to live on year around? Also, regarding buying such equipment - is there a way to pay less than MSRP from the manufacture for such equipment? (New not used). Thanks.
