The Progressive SDR-90 is a three point hitch version of the popular tri-deck TDR-22 mower and it utilizes many of the same components. Not to be confused with other, light duty three point hitch mowers that are available, the SDR-90 has a 6” diameter rollers on both the front and rear across the full width of the deck. Ideal for smaller mowing jobs where a quality cut is mandatory, the SDR’s rollers allow you to cut as low as ½”, while simultaneously striping and rolling the mowing surface. To minimize service requirements, the SDR-90 is equipped with field proven maintenance free blade spindles. Progressive’s SDR-90 mower is another example of the ingenuity and quality that goes in to producing a durable, reliable rotary finishing mower that is easy to maintain. It shows once again why the SDR-90 is “The Better Built Choice”.
