The Progressive SDR-90 mowers are a three-point hitch version of the popular tri-deck TDR-15 and TDR-22 mowers and they utilize many of the same components. Not to be confused with other, light-duty three-point hitch mowers that are available, both the SDR-65 and SDR-90 have 15 cm (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 1,3 cm, while simultaneously striping and rolling the mowing surface. To minimize service requirements, both models are equipped with field-proven maintenance-free blade spindles and HEX-Drive Roller-End bearings.
