The Earthwise 50120 is part of the lawn mower & tractor
test program at Consumer Reports. In our lab tests, push mower
models like the 50120 are rated on multiple criteria, such as those listed below.
Reflects a combination of evenness, which is how close the mowers came to even, carpet-like mowing, and how well the mower distributed its clippings over the lawn's surface.
Denotes a combination of evenness, which is how close the mowers came to even, carpet-like mowing, and how much clippings the bag held either before it filled or the chute clogged.
A combination of evenness, which is how close the mowers came to even, carpet-like mowing, and how evenly clippings were dispersed from the side-discharge chute.
Features & Specs - Earthwise 50120
Can bag Indicates whether the mower can cut in the bagging mode. In this mode, the clippings are gathered in a removable catcher. Lawns tend to have the best appearance after cutting in this mode because the mower essentially vacuums the lawn clean and leaves very little debris behind. This advantage is offset by the need to periodically empty the catcher and dispose of the grass clippings.
Can mulch Indicates whether the mower can cut in the mulching mode. In this mode, the discharge port is closed off, and the mower re-cuts clippings until they're small enough to settle and decompose in the lawn. Cutting in this mode reduces the need to fertilize the lawn because some of the nutrients from the clippings are returned to the soil. It is also more convenient because there is no need to empty a catcher or dispose of any clippings. Certain conditions are required for successful mulching, and if these conditions are not met, many visible clippings can be left behind on the lawn. For successful mulching, one should avoid cutting more than one third of the grass's length, cutting wet grass, or cutting at too fast a pace.
Can side discharge Indicates whether the mower can cut in the side-discharge mode. In this mode, the mower simply discharges the clippings off to the side of the mower. Depending on the length of the grass cut, this method tends to leave many visible clippings behind. This mode is preferable when cutting tall grass because the mower is less likely to clog, since the clippings are quickly removed from the deck.

Deck size (in.) Most models have a deck size, or cutting swath, of 20 to 22 inches. There is no significant advantage from one size to another. A larger deck can cut more grass in a single pass, but in this size range the difference is negligible.
Deck size (in.)
Engine size For gas-powered mowers, engine size in cubic centimeters (cc) provides a rough indication of the engine's power; electric models are rated in volts (for cordless) or amperes (corded). A larger number for either a gas or electric model, however, does not necessarily result in better cutting performance.
I bought this lawn mower with the good intention of moving away from a gas-powered mower. I have owned it for three years, and just had to purchase my 2nd replacement battery. I had to replace one of the rear wheels. The grip on the handle lasted less than one season, and the rubber guard below the trimmings bag folds under the mower too easily and has been shredded completely. I wouldn't be too bothered by most of this, but having to replace the battery every year at a cost of $141 is ridiculous. It also somewhat defeats the intent of an environmentally friendly lawnmower, since the stockpile of dead lithium batteries more than offsets the gas usage to cut a typically-sized lawn. It is unfathomable that a company like Earthwise wouldn't address this major shortcoming.

Easy to Push & Steer
Not sure about 2 of the previous reviews but the model 50120 is NOT cordless, it is CORDED. I've had mine for almost 4 years and not one problem. I do have a somewhat small lawns, 1 is about 19x27 and 2 is about 15x22, but it works very well for both. NOt had any issues with grass buildup on the underside of the deck. The only issues, and they are very minor, are that if the grass is somewhat wet, cuttings don't go into the bag as well as drier grass and not being able to buy a new blade unless you go online. You can't use a 'universal' replacement. I have however purchased a blade sharpener in the interim.

Battery Life Is Very Poor
Poor quality handle
Poor Quality Wheels
We purchased this mower in 2010, wanting to decrease our contribution to air and noise pollution. Great the first year, except the bag has never stayed on well while mowing. But in the second year we had to replace the battery. It is time to do that again, but we likely are not going to do that--overall quality is too poor.<br /><br />The handle broke in year 2 ½ at the point where it attaches to the deck. The wheels (like most mowers, unfortunately) are plastic and poorly made. If the battery life was better, and the components of higher quality, this would be a good mower for our small-yard needs. All cordless devices need to be made so the charger turns off when the battery is fully charged!
