Standard Features

Sidewinder® Cutting Unit System
 The Sidewinder cutting units shift left and right a total of 24 inches (61 cm). This increases the cutting unit overhang for precise trimming. The tire tracks can also be shifted within the mowing path to reduce wear on the turf.  
Operator Comfort
 Deluxe seat adjusts to let you customize your work environment and reduce fatigue. Plenty of space at the operator’s station paired with easy-to-read controls increases comfort. Plus the steering wheel tilts for steering preference.  
Quality of Cut
 The new 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. In addition, a unique directional vane and modified discharge opening deliver even clipping dispersion. An optional mulching kit is also available.  
Scalp-Free Mowing
 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.  
Attractive Striping
 Rear rollers provide an attractive striping effect while you mow, greatly enhancing the finished look of your turf.  
Superior Traction
 The patented 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.  
Time Saving
 Unlike any other mower on the market, the Groundsmaster® 3500-D allows you to be more productive. The 68 in. (173 cm) width-of-cut allows you to mow generous swaths, yet its compact size and the Sidewinder® system also allow you to make tight maneuvers in trim areas. So places that might normally require you to use one or two different machines can be handled by one.
