Mo-To is the first commercially available , radio control conversion kit for existing mowers. It attaches to your mower without any need for modifications. Its easy to attach and also easy to remove. You can even lend Mo-To to your neighbors, without lending them the mower.
There are plenty of D.I.Y persons having a go at RC Mowing on YouTube. Dont waste time fiddling about with messy mower mods, get going with Mo-To.
