Yeah, Big A in SC KS we just can't get away with 1/2, much as I'd like to. About 4-5 pm when it hits 105 she just gets to warm even if you clean the radiator every morning. It depends on which direction you are cutting vs the wind direction, but it is frustrating so we backed them down a smidgen. We run probably about 3/8 of a turn. It never occurred to me until now that a guy could probably give it that extra twist for cutting green stemmed soybeans in the fall though.
