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.

FEATURES

Lift-In-Turn Cutting Units

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.

Faster Transport Speeds

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.

Balloon Style Tires

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.

Exclusive Lift-Gate Footrest

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.

Leak Detection

The dependable Turf Guardian™ leak detection system provides immediate audio and visual indication of possible hydraulic fluid leaks.

Maximize Fuel Economy to Improve Cost of Ownership

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.

Proven Flex Suspension (Patented)

Superior contour following capability utilizes an integrated "Flex" linkage system to allow cutting units to pivot around the center of the front roller to master undulations and prevent side-to-side scrubbing of the putting surface.

Perfect Triangle Wheel Stand Design

The Triangle Wheel Stand places the rear wheel track within the radius of the front wheel, which prevents accidentally dropping the rear wheel into a nearby sand bunker while making the turn for the next mowing path.

Double A-Arm Suspension

The suspension system maintains full floatation range to prevent gouging or scalping when going over undulations.

DPA Cutting Units

The most advanced cutting unit in the industry:• Only two adjustments• Superior height-of-cut retention• No daily greasing (stainless steel bearings)• Consistent cutting edge regardless of reel wear (patented)• Smallest bedknife increment adjustments .007 inch (.178mm)

Tool-Free, Quick-Change Cutting Units

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.

EdgeSeries™ Reels

Dual Precision Adjustment (DPA) cutting units – featuring Toro’s EdgeSeries™ reels combine to deliver a consistent, high quality cut and superior after cut appearance, while reducing maintenance with improved reel edge retention.

Clip Control (Dial-In Clip)

Maintains consistent clip even during clean-up cut when operators slow down.
