All lawn mowers have one basic flaw. Get rid of it and it’s much lighter, goes faster, goes under low branches and between bushes, turns on a dime, saves gas, mows in the rain and lets you have fun to as well. That flaw is the rider. So we made radio-control mowers. Here’s a good resource for making your own remote controlled lawnmowers. Link. Thanks Ken!
