What is a commercial or rough duty flail mower?

If you have a large property that has to be maintained, these flail mowers are built to handle long, extended mowing runs. Some have special features such as adjustable hydraulic offsets or centered mowing. All have reinforced decks and can handle rough conditions. All of these units use 27 oz hammer blades that can handle woody material up to 3″ thick. They can also be used with 10.9 oz Y-Blades.
