i actaully thought about it, there the backup cams arent they?? i have seen them...

we have a wonderful store here called "princess auto", its a surplus store. sprockets were a dollar each, chains were $8 for 6 feet.

it was actually designed as a snow plow, not a lawnmower. we have a driveway big enough for about 6 cars, and its a real pain to shovel it. at no load, the motors run at about 1.4amps each, and when im sitting on it, riding around, it runs at about 3.5 amps each. in a couple minutes, i will upload the new board design, and see what you guys think, then maybe i will make a new one..
