Stump grinding as a niche service . . . ? My business model is basically a major in the Spring and Fall services: aeration, Rototilling, lawn dethatching and over seeding - all my equipment is WB. I have few mowings on regular basis but I was looking for something to help the cash flow until the Fall. Is stump grinding a good area to get into . . . or is this really more of an arborist specialty.
