Greenworks 25302 Features and Specifications

With 20 inch cutting deck and 40V dual G-Max lithium battery pack, Greenworks 25302 is intended for mid-sized yards.

Unit is rather light, weighing around 42.5 pounds (~19.3 kg) and thanks to the 10 inch (25.4 cm) rear and 7 inch (17.8 cm) front wheels, Greenworks 25302 is rather maneuverable unit - after all, there is no power cord to pull around the yard.

Blades' no load speed is 5000 rpm (~84 rotations per second!) ensuring clean cut. Due to the twin blades, Greenworks 25302 is designed as 2-in-1 unit - it can be used for mulching or it can collect the grass clippings in the rear semi-rigid collector bag.

Greenworks 25302 is powered by Greenworks G-Max 40V lithium ion batteries featuring capacities of 2.0, 4.0 or 5.0 Ah, with or without USB charging port.

During operation, Greenworks 25302 uses only one onboard battery, allowing the user to quickly switch from one battery to the another - this also allows the user to charge the empty battery, while charged battery is in the lawn mower.

Greenworks G-Max 40V lithium ion batteries may be used to power dozens of other cordless Greenworks tools, including trimmers, chainsaw, blower etc.

Since Greenworks 25302 may be ordered as 'bare tool' or with 2.0/4.0 Ah batteries and charger or with 5.0 Ah battery and charger, initial investment in the cordless lawn mower with batteries and charger allows the user to purchase tools in the future as 'bare tools' at rather affordable prices.

Greenworks G-Max 40V lithium ion batteries that also feature USB charging ports may also be used as small power banks for charging USB devices like smartphones, tablets, USB flashlights etc - keep in mind that one fully charged 40V 5.0 Ah battery stores ~180 Wh of energy, and that is a lot of energy.

 In order to improve operating time, Greenworks 25302 features so-called 'Smart Cut' technology which adjust the blades power according to the thickness of the grass and condition of the blades - the sharper the blades, the longer operating time on the single battery charge.

Cutting height may be changed using single lever and it varies between 1 3/8 and 3 3/8 inch (3.5 and 8.5 cm), which is more than enough for most yards.
