Remote Controlled Lawnmower

Remote controlled lawnmower. The mower deck is a 22 inch Weedeater from WalMart. The wheel chair motors are Merits. The motors run at 12 volts and the battery is recharged by a GM alternator. The transmitter is a Futaba T4YF. The speed controllers (2) are from Astroflight.

The mower has been in service for over 5 years and works great!

Very Cool! Can you tell me what gm alternator you used? I am trying to make one now. I have the basics. motors, controller, radio, lawnmower. Wanted to add a alternator and a failsafe switch. Awesome, thanks for the contribution.

As far as alternators go, there are a number of one wire GM alternators available. These used by a lot of hobbyist because they are so easy to hookup.

A good source for GM alternator is Dale Marlin (918-519-6839). Dale rebuilds alternators and sell them for around $65 to $70 plus shipping from Oklahoma. You will need a pully with 2 v-belt grooves. You use the 2nd groove (farthest away from alternator) to clear the mower deck.

Dale is honest and does a good job rebuilding them. Get 1 GM 1 wire the puts out 65 amps.

Good luck!

eBay is a good source for wheel chair motors. The ones I used are Merits Part #'s WMT90423 and WMT90424.
