Product Overview

I recently tried out the Greenworks 40V Brushless Self Propelled Lawn Mower and I have to say, it is an excellent mower. It has some great features that make it stand out from other mowers.

First of all, its powered by a 40V battery, which means you dont have to worry about refueling. This makes it a great choice for those looking to reduce their carbon footprint. The battery also provides up to 45 minutes of run time so you can easily finish your yard work without having to recharge the battery. The brushless motor is also very powerful and efficient, providing more torque and longer life than many other electric mowers.

Another great feature of this mower is its single lever height adjustment. It has seven different positions so you can get the perfect cut in any environment. And with its 3 in 1 design, you can easily switch between rear bagging, side discharge, and mulching capabilities so you can always get the job done quickly and efficiently. Plus, its self propelling rear wheel drive power increases traction so you can tackle the toughest terrain with ease.

Finally, this mower is virtually maintenance free as there is no need for gas or oil, making it incredibly easy to use and maintain. Plus, it starts instantly and runs quietly so you wont disturb your neighbors while taking care of your lawn. Furthermore, it takes up only 70 of the space due to its vertical storage feature which makes storing this mower a breeze.

Overall, I would highly recommend the Greenworks 40V Brushless Self Propelled Lawn Mower for anyone looking for a reliable and efficient electric lawn mower that is easy to use and store. It s great for small yards as well as large ones thanks to its powerful 40V battery and single lever height adjustment capabilities. And with its 3 in 1 design and self propelling rear wheel drive power you ll be able to take on any terrain with ease while keeping your lawn looking beautiful every season!
