2026 Toro Greensmaster TriFlex 3420

Overview

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.

• Suspension system is designed to provide a slight lift to the inside of the cutting units during turns resulting in more consistency of cut
• Provides braking power to stop reels from spinning when cutting units are disengaged
• Stay ahead of golfers and get more greens cut in a shorter time
• The most advanced cutting units in the industry
• Switch from cutting greens to cutting a fairway in just minutes
• Perform routine maintenance and repairs with easy access to the center cutting unit
• Turf Guardian™ leak detection technology alerts the operator to any leaks
• View common operational settings in the InfoCenter™
• Operate efficiently in energy savings mode where engine RPM's are reduced and the all-electric reel drive maintains a constant reel speed
• Independent reel motors ensure a consistent clip during clean-up cuts and speed changes
• Redesigned tires deliver uniform loading across the entire cross-section to reduce visible tire tracks
• Clipping capture system retains nearly all grass clippings for a cleaner and healthier cut
• Electrical connectors and components are completely protected during wash down
• Suspension system maintains full floatation range to prevent gouging or scalping when going over undulations
• Each reel motor has a nominal 1.5 horsepower (1.1 kW) to ensure the power you need
• Wheel layout and turning radius prevent accidentally dropping the rear wheel into a nearby sand bunker while turning
• Integrated "Flex" linkage system allows cutting units to pivot around the center of the front roller
• Deliver a consistent, high quality cut and superior after cut appearance, while reducing maintenance

Features may include:

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.

Stored Energy

• 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.

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.

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 .007inch (.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.

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.

InfoCenter™: Advanced Control for Hybrid Models

• 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.

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.

Clip Control (Dial-In Clip)

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

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.

Superior Clippings Capture

• Redesigned clipping capture system maintains a consistent gap between the basket and reel to retain nearly all grass clippings for a cleaner and healthier cut. In addition, a discharge shield forces clippings inside of basket and minimizes "blow-by".

Sealed Electrical Components for Worry-free Wash Down

• The electrical connectors and components are completely protected permitting machine wash down without worry.

Double A-Arm Suspension

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

All-Electric Reel Drive

• In addition to eliminating hydraulic leaks, each reel motor has a nominal 1.5 horsepower (1.1 kW). This translates into the power you need when you need it for unparalleled performance in your most challenging cutting applications.

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.

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.

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.
