Contracts Written proposal agreements Things that are signed saying what the price represents. Like "the turf will be cut between 2.75" and 3.5" depending on weather and conditions" They signed it There's there's the price. They want 2-2.5"? That's a different price and a higher frequency. The first contract might be for $50 a cut and 30 cuts. Second one might be $60 a cut and 33 cuts. Eow/biweekly cuts trying to get you to cut shorter are trying to save money. They are trying to get "two cuts worth" for the price of one. Dont let them do that Either they are cut higher or more often or their yard is legit a non grower, those are the only options.
