I know a guy who has a big company out here in Long Island and he does weekly cuttings 2 sometimes 3 weeks into November. He says 98% of his customers are okay with it as well. His Excuse: He tells his customers that if they don't let him cut well into November, then thier fallcleanup bill will be a lot more money, because he's sucking up all the leaves in November instead of really cutting the grass. This is actually a clever idea I think. Anyone disagree with this. I already had a couple tell me to stop cutting for the rest of the year, It sucks to have your income dwindle towards the end of the year until the cleanups start.
