Toro Reelmaster 3100-D Ride-on Mower

Toro

Toro® Reelmaster mowers are lauded for their quality of cut, and the 3100-D is no exception. Your choice of 5, 8 or 11-blade reels let you customize the cutting unit to fit a variety of applications. Variable reel speed adjustment offers even greater operator control while onboard backlapping helps keep blades sharp. All this comes in your choice of 183 cm or 216 cm cutting widths to keep you more productive.

The Reelmaster® 3100 is the revolutionary triplex mower designed for superior performance on all types of turf. The optional Sidewinder® cutting units can be shifted right and left, on the fly, for increased reel overhang and to vary the tire tracks. The powerful Kubota® 21 hp (15.7 kw) engine and exclusive Series/Parallel 3WD traction drive system gets the mowing job done quickly. And the unique machine layout, with the engine in the rear and the operator out front, allows the operator to mow comfortably and productively, while the mechanic has fast access to all service items.

The Reelmaster® 3100-D is available with Sidewinder® – Toro’s exclusive system that gives operators the ability to shift all three reels left or right while on the fly – providing up to 23″ (58 cm) of overhang and decreased tire tracking.

The Reelmaster 3100 is also commonly known as: RM 3100, RM3100, Reel master, Reel master 3100, Toro reel master, reel mower
