Andover entrepreneur Mike Cofrin’s idea for a zero-turn-radius push mower never quite took off the way it was supposed to, so he’s clearing out his garage, and waiting for the next wave to take off. $329, invented in his garage; steers better than the traditional mower, plus it has a Scott’s Classic mower body, and 5 lbs of weight for your workout.
