This radio controlled lawn mower was built using two Homelite 20 inch walk behind electric mowers, one power wheelchair, two boat batteries, one RC transmitter and receiver, two quarter scale servos, one Sabertooth dual 32 motor controller from Dimension Engineering, and misc. stuff from the local Lowes Home Improvement store.
I used the contact switches from the mowers and the quarter scale servos because the switches were usable and I already had the servos laying around. No out of pocket expense.
I sourced the mowers and wheelchair from Craigslist over the last two years. It was luck that I found two identical mowers.
