The deck is made of steel for durability and has a rust-resistant powder-coated finish to withstand the elements. It features 2 durable steel blades that deliver a clean, even cut.

The smooth adjustability makes it easy to go from one cutting height to another quickly. Overall, the 21-inch cutting deck with adjustable height provides versatility for mowing different areas of your lawn.

Motor & Battery Life

Many users report the battery holds a charge well even after a couple seasons of use. Greenworks backs it with a 4 year warranty, so you can mow with confidence knowing the battery is covered. Overall, the 80V system delivers impressive power and runtime that makes quick work of most mid-sized yards.

Handling & Maneuverability

The Greenworks 21-inch 80V cordless electric lawn mower scores high marks when it comes to handling and maneuverability. Weighing in at just 60 pounds, it is significantly lighter than gas-powered mowers which can weigh over 100 pounds. The lightweight design makes the mower easy to push and maneuver around the yard and landscaping obstacles.

The rear 10-inch wheels and 7-inch front wheels provide a smooth roll across lawns. The wheels are slick plastic rather than rubber pneumatic tires, but this helps reduce the overall weight. While pneumatic tires may provide slightly better traction, especially on bumpy or hilly terrain, the plastic wheels are more than adequate for typical flat or gently sloping suburban yards.

The compact 21-inch width allows the mower to fit easily through gates and other tight spaces. The handle adjusts to multiple height settings to accommodate users of different heights. And the vertical storage capability helps save precious garage space when not in use.

Overall, the 80V Greenworks lawn mower offers easy pushing, smooth turning, and lightweight handling ideal for maneuvering around landscaping, trees, and gardens. The slick rear-wheel drive design avoids any pulling or dragging. And the vertical storage position offers a major space-saving advantage for storage versus gas mowers.

Cutting Performance

The Greenworks 21-inch electric lawn mower provides excellent cutting performance for most residential lawns. Its 21-inch steel cutting deck allows you to cut a large swath of grass in a single pass, reducing mowing time. The design of the cutting deck also promotes efficient mulching and bagging of grass clippings.

The mower provides a clean, even cut each time thanks to its precision-cut steel blades. It cuts grass cleanly without ripping or tearing. The cutting height is adjustable between 1-3/4 inches to 3-3/4 inches, in 7 different position settings, allowing you to maintain your desired lawn height.

For mulching, the mower does an excellent job of cutting grass clippings into tiny pieces that are then dispersed into the lawn. No clumping occurs and there are minimal grass clippings left on top of the lawn. The mower also has a large 2.6 bushel grass catcher if you prefer to collect clippings. The catcher bag fills evenly and is easy to empty.

Overall, the cutting performance matches gasoline mowers, providing a manicured lawn look. The mower handles thick and tall grass well on a single pass. The 21-inch width allows you to mow quickly and achieve an even, consistent cut on your entire lawn.
