More Info

• The unique Toro Series/Parallel™ traction drive system provides steady traction in all conditions, even in wet grass and over undulating terrain. Its full-time, 3-wheel drive system maintains power to two of the three wheels at all times, minimizing tire spinouts and scuffing.
• Sidewinder cutting units shift left and right a total of 24 inches (61 cm). This allows the tire tracks to be shifted within the mowing path to reduce wear on the turf.
• The Contour™ Plus cutting technology takes quality of cut to a whole new level. Air inlet pockets keep the grass standing tall for the cleanest possible cut, while an acceleration baffle speeds clipping circulation and assures maximum power.
• The ground-following design of each Contour™ Plus free-floating deck permits mowing the most challenging berms without scalping. Two front rollers and a rear roller allow the deck to smoothly pass over turf.
