Progressive SDR Roller Mower

Progressive's three point hitch roller mowers employ the same deck design as the Tri-Deck Roller mowers. These mowers can be used for maintenance mowing, municipal grounds, estates, sports fields and many other lawn and turf applications where a quality cut is desired. The mowers cut as low as 13 mm (1/2") and provide an even cut without scalping.

Like all Progressive products, the mowers are a heavy duty design for superior strength and durability. The SDR mowers are available in 1.6 m (65") and 2.3 m (90") cutting widths, and can be either rear or front mounted.
