A cordless lawn mower cuts the gas, the oil and the pull cord. These three self-propelled battery mowers come from EGO, Greenworks and SKIL, and each one ships as a kit with a battery and charger.
How We Chose
We picked three well-known brands that make a self-propelled cordless mower kit with a battery and charger. They are not identical: the EGO and Greenworks have 21 inch decks and the SKIL has a 20 inch deck, the battery systems are 56, 60 and 40 volt, and the kits include one 7.5Ah battery, two 4.0Ah batteries and one 6.0Ah battery. Runtimes are each brand’s own stated figure with its own kit, so they are not a like-for-like test. Specs come from each manufacturer’s own pages, and the weights marked with an asterisk come from the Amazon listing because the manufacturer pages do not state them.

Check Price on Amazon →Our Take
Pick the SKIL if price matters most, the Greenworks if you want two batteries in the box at a mid price, and the EGO if you want the 5 year mower warranty and Touch Drive speed control and the price difference is acceptable. Compare the 20 versus 21 inch decks and the different battery platforms before you buy, especially if you already own cordless tools from one of these brands.
