I don't understand this. ^^^^ Are you running commercial mowers or the old nut and bolt adjustment type. Keep a log of the height for each customer. Do this now so when you get 10 crews the crew chief will know the height. I will add, I mow whatever the customer wants, as long as the blades don't hit the ground. I have one that the 21 honda is on the lowest setting which is around 1 3/4". Burmuda and yes it turns brown, but greens backup and all and all doesnt look too bad.
