The Toro 3500-D Sidewinder is a professional-grade, diesel-powered rotary mower designed for high-quality turf care on undulating terrain. Its key feature is the “Sidewinder” system, which allows the cutting units to shift left and right a total of 61 cm (24 inches). This provides increased cutting unit overhang for precise trimming along edges and allows the machine’s tire tracks to be shifted to reduce turf wear.
