Mow with one of the most impressive mowing decks in the world. Imagine the perfection you will achieve with three 42" decks. This gives you the productivity of a 10'-6" mower with the precision cut of three much smaller mowers. The Model 621EF utilizes a patented self-tensioning belt drive system that is efficient and maintenance free. The 621EF is a highly maneuverable mower in a compact package and can be lifted by the tractor for transport.
