Mow with one of the most impressive mowing decks in the world. Imagine the perfection you will achieve with three 42” (106.68 cm) decks. This gives you the productivity of a 10’ 6” (3.2 M) mower with the precision cut of three much smaller mowers. The Model 621ER utilizes a patented self-tensioning belt drive system that is efficient and maintenance free. The 621ER is a highly maneuverable mower in a compact package and can be lifted by the tractor for transport.
