Unpacking the Power Behind the Brushless Motor Technology
The heart of this mower lies in its 40V HP brushless motor, a game-changer that delivers the power and endurance traditionally reserved for gas-powered machines. Unlike brushed motors, this advanced brushless design reduces friction and heat buildup, giving us longer motor life and more efficient energy use. This means we can mow for up to 70 minutes on a single charge without losing torque or performance, thanks to the dual active battery ports and high-capacity 6Ah batteries. It’s impressive how the motor adjusts seamlessly, ensuring smooth power delivery while maintaining whisper-quiet operation, which is a signature trait of the series.
Additionally, the SMART TREK all-wheel drive system works in perfect harmony with the motor, intelligently matching the mower’s pace to ours as we navigate uneven terrain or slopes. This synergy not only enhances control but reduces fatigue during long mowing sessions. The multi-blade system also maximizes cutting efficiency by switching effortlessly between double blades for a precise cut and single blade for extended runtime. Below is a quick look at some key motor and performance features:
| Feature | Benefit |
|---|---|
| Brushless Motor | Longer motor life & reduced maintenance |
| 40V HP Technology | up to 70 minutes of run time |
| SMART TREK All-Wheel Drive | Adjusts speed to user’s pace for increased comfort |

The 11-inch high wheels contribute to smoother handling and improved traction, making tight turns and tricky corners feel intuitive rather than strenuous.
Comfort is further amplified by the thoughtfully designed one-touch aluminum handle, which folds easily for compact storage and reduces fatigue during use.With the mower’s balanced weight distribution and quiet operation - thanks to the whisper-quiet brushless motor – every mowing session becomes less taxing and more enjoyable. Hear’s a quick overview of the key self-propelled features contributing to comfort and control:
- All-Wheel Drive: Superior traction on slopes and rough patches
- SMART TREK Technology: Matches speed seamlessly to user pace
- 11″ High Wheels: Smooth navigation over grass and debris
- Foldable Handles: Ergonomic design for easy transport and storage

Evaluating the Cutting Performance on Various Lawn Types
We put this mower to the test across different grass conditions, from fine Bermuda to thick, damp fescue, and it consistently delivered clean, precise cuts. The dual blade CROSS CUT Multi blade System is a standout feature, allowing us to easily switch between two blades for a superior finish or one blade for longer runtime. This flexibility means it handles fine grasses with minimal shredding, while powerfully slicing through dense patches without bogging down. The 21″ cutting deck, combined with the all-wheel drive and SMART TREK technology, adapts smoothly to uneven terrain and varying grass heights without requiring much effort from us.
Adjusting cutting heights is effortless, with a seven-position single-point lever letting us tailor the mower to different lawn types, from a close clip to a more natural look. The integrated mulch plug enhances versatility; mulching thicker or damper grass helps prevent clumping, while side discharge or bagging options maintain tidiness when dealing with heavy clippings. Below is a quick overview of cutting performance based on tested lawn types:
| Lawn Type | Cut Quality | Best Mode | notes |
|---|---|---|---|
| Bermuda Grass | Clean & Precise | Dual Blade Mulching | Less shredding, even finish |
| Fescue | Powerful & Smooth | Single Blade Bagging | Handles dense blades well |
| Zoysia | Even & Consistent | Dual Blade Side Discharge | Prevents clumping/matting |
| Kentucky Bluegrass | Neat & Tidy | Mulching or bagging | Effortless clipping management |
the combination of brushless motor efficiency and intelligent speed matching provides a consistently smooth mowing experience irrespective of lawn variability. It excels especially on medium to large yards where endurance and reliability are key, making it a great companion for diverse grass landscapes.
