GreenWorks offers its GreenWorks 20" G-MAX Twin Force Cordless Mower for $349 with free shipping. That's the lowest total price we could find for a mower with only one battery by $21, although we saw it for $61 less in April. It features up to 70 minutes of run time, five height positions, dual blades for mulching, hard-top rear bag, 10" rear wheels, 7" front wheels, and includes two 40V batteries and a charger.
