Greensmaster eTriflex 3370

Model: 3370

Meet the all-new electric Greensmaster eTriFlex range from Toro. The new Greensmaster® eTriFlex models carry no hydraulic fluid and utilize all-electric components for traction, steering, lift and cutting.

The eTriFlex 3370 model boasts a 48-volt Lithium-Ion Samsung® battery, offering a virtually silent operation on any green. This fully electric mower is very energy efficient and an extremely comfortable ride.

These EnergySmart® models are operationally friendly with noticeable noise reductions, operational cost savings, and other meaningful improvements to complement the ever-important enhancements in cutting performance.

The Greensmaster eTriflex 3370 is also commonly known as: GM3370, GM 3370, Greenmaster, Green Master 3370, GMeTriflex, eTriflex 3370, Toro Greensmaster

Combining the innovative, Double A-Arm Suspension System with industry-leading Flex technology, the cutting units float freely over any terrain.

The new Radius Dependent Speed (RDS™) System, in combination with the Lift-In-Turn cutting unit leveling feature virtually eliminates the effect known as “Triplex-Ring”. This substantially improves both the aesthetics and playability of the green. And superior cutting performance is only the beginning.

The patented Lift-Gate Footrest, Tool-Free QuickChange™ cutting units, Automatic “Slow-in-Turn” during Transport and Auto-Brake on Operator Dismount are just a few of the many new features that provide added versatility, simplified service, and ultimately, more productivity.

It is unsurprising for the bar to be raised even higher by the world class Toro group – count on it.

Harness full Electric power and go virtually silent

The industry-first lithium-ion based battery powered unit also has ample power and is virtually silent during operation. The new generator model, according to end users familiar with the new product, is much quieter than traditional engine powered models.

Radius Dependent Speed (RDS) System for Optimal Perimeter Cut

The Greensmaster eTriFlex 3370 maintains a consistent cutting unit clip rate in turns on each individual reel. Extra wheel speed control is included during turns for reduced wheel scrubbing and optimum control. A lift-in-turn feature is included to provide a level cut from side to side, particularly in turning.

Advanced Cutting Performance

Double A-Arm plus Link-System Suspension provides superior contour following while riding. Industry-leading Flex™ technology and DPA cutting units allow for simple adjustment and a refined precision finish.

Highly Productive and Versatile

Both new eTriflex machines have ample power for a wide range of applications both on and off the greens. Whether considering the 3360 or 3370versatility and productivity are the goal made possible by Toro.
