obtain a clean cut.
Under certain conditions, tractor tires may roll some grass down and prevent it from
being cut at the same height as the surrounding area. If this occurs reduce the tractor
ground speed but maintain a 540 rpm engine speed. The lower ground speed will permit
the grass to at least partially rebound. Under some conditions grass will not rebound
enough to be cut evenly, resulting in an uneven appearance. In general, lower cutting
