Until now electric lawn and garden tools meant disappointing power and limited runtime. But cutting-edge battery and engine tech have produced a new generation of gear with enough muscle to power a 710-lb ride-on mower for an entire acre of grass, or a chainsaw for 35 minutes of slicing logs.
This versatile 40-volt lithium-ion string trimmer cuts a 13- or 15-inch path through the thickest grass and weeds, reaching places that are inaccessible to your mower. Plus, it has enough power to run two string lines and the endurance to cut up to an acre's worth of grass on a single charge. And if you want to expand your arsenal, you can attach a blower, pruner, or edger, sold separately. [$179; ryobitools.com]
