I've never used one, been mowing my own for decades (except for when we lived in apts), but because it's been so wet and so hot and so humid (and that's only probably going to get worse in my lifetime), I'm having to mow more than weekly, and I just don't want to deal with it anymore. I adhere to the best practice for Bermuda - start off around 1" - 1 1/4", then raise it 1/4" every holiday. Can anybody recommend a company that will do that? Or do they all pretty much just set it at one height and leave it that way for everybody they do all season? TIA...
