Overview
  • The suspension system is designed to provide a slight lift to the inside of the cutting units during turns to deliver a consistently level cut and to reduce "triplex ring" for improved playability and turf health.
  • Eliminates clip marks at the startup of a mowing pass and provides braking power to stop reels from spinning when cutting units are disengaged for safer operation.
  • Ten miles per hour (16.1 km/h) transport speeds will allow you to stay ahead of golfers and get more greens cut in a shorter time.
  • A single operator can go from cutting Greens at 0.125" (3.2 mm) to cutting a Fairway at ¾" (19 mm) in just minutes. The tool-free, quick-change cutting units make it as easy as 1-2-3.
  • Easy access to the center cutting unit facilitates routine maintenance and repairs, simplifies adjustments, and eliminates the need to put the traction unit on a lift for cutting unit service saving you time, money, and frustration.
  • The dependable Turf Guardian™ leak detection system provides immediate audio and visual indication of possible hydraulic fluid leaks.
  • Easily customize clip for different heights of cut and adjust other operational settings to gain complete machine control. Common operation information displayed includes: reel speed, hours of function, system voltage for reels, diagnostic descriptions, and much more.
  • With more than enough horsepower and highly efficient components, the TriFlex Hybrid models operate efficiently in energy savings mode. While in this mode, engine RPM's are reduced and the all-electric reel drive maintains a constant reel speed. This results in reduced fuel consumption and noise while maintaining quality of cut, performance, and productivity.
  • Maintains consistent clip even during clean-up cut when operators slow down.
  • Tires have been redesigned to deliver uniform loading across the entire cross-section (load footprint area) to eliminate side wall loading that can create visible tire tracks.

The Greensmaster® TriFlex™ Mowers were designed to take precision cutting on a greens mower to a completely new level. Adopting the proven Flex suspension, the cutting units float freely over contours and undulations of the green resulting in a superior quality of cut and aftercut appearance. Improved serviceability is another major advantage of the TriFlex™ models. The tool-free, quick-change cutting units make servicing the cutting units fast and easy and a lift-gate footrest provides easy access to the center cutting unit.
