Groundsmaster® 3500-D (30839)

  • 35 hp (26 kw) Turbo-Charged Kubota® Diesel Engine
  • Free-Floating Contour™ Plus Decks

  • Series/Parallel™ 3-Wheel Drive Traction System
The Groundsmaster® 3500-D is a revolutionary triplex rotary mower designed for superior performance trimming. The free-floating Contour™ Plus cutting decks allow mowing of undulating terrain without scalping. The powerful 35 hp (26 kw) Kubota® engine and exclusive Series/Parallel™ traction drive system, gets the mowing job done quickly.

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 operators station paired with easy-to-read controls increases comfort. Plus the steering wheel tilts for steering preference.

Powerful Engine

Kubota® 35 hp (gross) turbocharged liquid-cooled, 3-cylinder, diesel engine provides an abundance of power to handle demanding mowing applications.

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.


The Groundsmaster® 3500-D is a highly versatile machine for a variety of applications. For golf courses it delivers a superior quality of cut on green and tee surrounds, as well as tight trim area such as bunkers, clubhouse lawns, and around trees.

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" (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.

Atomic® Mulching Blades

Atomic® mulching blades feature an aggressive "tooth" design that shreds grass and leaves into small particles. The teeth curl upward behind the blade to suspend clippings in the chamber so they are cut and re-cut until they virtually disappear.

High Height Blade

A new higher height of cut blade is now available in addition to the standard blade. This blade creates more lift and should be used in higher height of cut application. While there is no absolute height where the blade should be used, it should generally be used beginning at 2-1/4" (5.7 cm) or 2-1/2" (6.4 cm) height of cut.

Leaf Mulching Kit

Mounts to the deck to pulverize fallen leaves into fine mulch.
