The Reelmaster® 3100-D is powered by a 3-cylinder Kubota® diesel, and is equipped with manually adjustable variable reel speed and on-board backlapping. With available 5, 8, and 11 blade DPA Cutting Units, the Reelmaster® 3100-D will provide a precision cut for a wide range of applications.

  • Powerful Engine: With a 21.5 hp (16 kw) Kubota® Diesel Engine, the Reelmaster® 3100-D has the power to climb and power to cut through difficult mowing conditions.
  • Dual Precision Adjustment (DPA) Cutting Units: Precision machined cutting units maintain levelness and hold adjustments. DPA allows quick bedknife to reel adjustment. Harder reel and bedknife steel retain a sharp edge up to 3 times longer to minimize the need and frequency of adjustments, backlapping and grinding leading to healthier turf that stays green.
  • 72" or 85" Width of Cut: The Reelmaster® 3100-D is available in a 72" or 85" (183 cm or 216 cm) width of cut. With a choice of 5, 8, and 11 blade reels and adjustable reel speed control, this mower can be configured to meet all mowing applications.
  • Superior Traction: The patented Series/Parallel 3-wheel drive system provides power to at least two wheels at all times. The result is impressive traction in hilly and wet conditions, and minimal wheel slip so it's gentle on the turf.
  • Ease of Service: With the engine located in the rear of the machine, the Reelmaster® 3100-D is easy to service. Open the engine compartment to have access to all filters, fluids and engine components for fast preventative maintenance.
  • Out-Front Operator: The operator sits out-front on the Reelmaster® 3100-D for better mowing visibility and easier access getting on and off the machine. Engine noise, vibration, and exhaust are all located behind the operator.
