Operation differences in grass condition, grass length removed, and personal preference of the superintendent. For a cut with more grass removed but slightly more clip visibility, move the reel speed selector knobs one position lower than specified. For a cut with less grass removed and slightly less clip visibility, move the reel speed selector knobs one position higher than specified.
