I believe most mowers have a 3 year warranty so adding that additional year means they must really believe in their product. Normal stock mower blades perform well on dry, shorter grasses, and are optimized for efficiency, while high lift blades work better in extreme conditions. The high-lift blade has deeper curves on the ends, which increase suction to circulate and expel the clippings.
That said, it lacks the onboard controls and Wi-Fi connectivity that you get with our Editors’ Choice winner, the $999 Worx Landroid M 20V Cordless Robotic Lawn Mower . Right out of the gate we wanted to test the performance of this lawnmower. Having already tested the commercial model, we wanted to understand what translated to the consumer version. When you have larger blades nearly 24-inches across, you need a solid brushless motor to make it all work. Currently, no other manufacturers make a battery-powered consumer model with a deck this wide.
This results in more power when and where it’s needed. When you don’t, the mower operate at more conservative numbers—saving runtime. And, if you want to manually ramp up your power, just hit the Turbo button anytime. The Greenworks Pro has a 60-volt brushless motor with push-button start provides more power, torque and longer life without the hassle of gas. A brushless lawn mower is one where the motor can automatically adjust to the power needs of the job.

Plan your mowing pattern to avoid discharge of material toward roads, sidewalks, bystanders, and the like. Also, avoid discharging material against walls or obstructions, which may cause discharged material to ricochet back toward the operator. Always wear safety glasses or safety goggles during operation and while performing an adjustment or repair to protect your eyes. Thrown objects that ricochet can cause serious injury to the eyes. Always use a face or dust mask if the operation is dusty.
The Settings and Position button opens a screen where you can manually create work schedules to have the mower come out at a certain time on specific days of the week. Or you can use the Scheduling Wizard to create a schedule based on your lawn size. Simply use the slider to tell the wizard how big your lawn area is, select day or night for preferred working hours, and the wizard will automatically create a schedule based on your input. Up to 60 minutes run-time with fully charged 4.0Ah battery. Run-time varies based on grass condition and operator technique.
Everyone wants to know runtime for a mower—so we did our best to test it. So then it just depends on how well the system utilizes the batteries in managing both metrics. We fully charged the two 4Ah Ultra Power batteries included in the kit and inserted them into the mower. We first cut a large area of grass at the mower’s maximum height of 4-inches. Then, we dropped the deck all the way down to 1 3/8-inches to see if it would cut. Typically, when finding the minimum effective cut height, we have to raise the deck a couple of notches.
