Contractors who don't like the hassle of a gas engine and who already are invested in DeWalt's 20V Flexvolt battery platform might be interested in the new DCMW220 brushless electric mower, which is powered by two of DeWalt's DCB205 20V/5.0Ah batteries. Landscapers who are using the company's 40V platform for other outdoor power equipment can opt for DCMW290, the 40V version that runs on a single battery. Both versions feature a brushless motor, a folding handle for storage, and front and rear deck carrying handles for easy transportation. The company says that the mowers, which can mulch, bag, or rear-discharge, are suitable for yards up to 1/4-acre in size. MSRP for the bare 40V version is $299; with either a 40V battery or two 20V batteries and a charger, the MSRP is $399. dewalt.com
