The Reelmaster® 3100 is a revolutionary triplex mower designed for superior traction and cutting unit performance on all types of turf. A powerful Kubota® 21.5 hp (16 kW) engine and the Series/Parallel 3WD traction drive system provide the power and traction to get the mowing job done quickly. The operator area is designed for optimal operator view and all day mowing comfort. And mechanics will appreciate the fast and easy access to all service items.
Features may include:
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.
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.
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.
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.
Superior Traction
There's no need to worry about mowing around objects while traversing hills, even in wet terrain. The parallel hydraulic flow between front and rear wheels assures full-time 3-wheel drive. And the individual wheel brakes provide effective traction assistance on wet turf.
