Need Help Wiring Remote Control Lawn Mower

Hi all,

This is a great forum and I am glad I found it!
I am working on a 4wd remote control mower build. Here is what I have:
20 hp electric start briggs gas engine
DX5E controller
2 battle switches
sabertooth 2x60 motor controller
2 x wheel chair motors

This is the second remote mower project, the first one turned out great but it did not have electric start or electric deck adjustment. I need help figuring out how to wire the starter to start the gas engine via the remote. I also need help wiring an electric screw jack to be able to adjust the deck height up and down via the remote control. Any help would be GREATLY appreciated.

:)Can you tell us where you obtained the tires and wheels? I have a steep slope and have not been able to come up with solution for grip. Thanks, bc:)

I to am building a remote controlled lawnmower like @realvetteguys. Like him I am a little stuck on the starter set up as well. I've seen the set up that he was talking about using the battle switches as well. There is no wire diagrams and very little explanation of how it is wired up though. I do know that the example that is shown is using a 12v relay, not a starter style relay that is normally open as a safety system in case it looses signal to the receiver. It is a strictly RC system. He is not using an EZB. This is also how I am starting mine. Eventually I want to convert it to be more autonomous, but right now I will be happy to just get it to work.
I have been playing around with the idea of another motor controller to operate the starter. I don't need the pwm though. A relay would probably be best, I know. Obviously, since the mower already has one, It's a matter of actuating it until the engine starts, then shutting it down. My system uses a 6v battery to start it. I can't tell you the amperage; haven't found any specs on it , and I haven't tested it yet. I am wondering if a LM298 motor controller could be used to actuate the relay? Especially since it is only 6v. Hearing he blew the battle switch, I'm afraid to try it on mine.
I haven't tried anything as of yet, due to lots of overtime at work and waiting for parts to arrive. But tomorrow I'm off and that is one of my top projects. I'm going to try the LM298 to see, unless someone has a better idea.

Hi @Rod
I am not sure how @real57vetteguy had his wiring hooked up but seems to me the Battle Switch should work fine to pull in the solenoid coil. The Battle Switch contacts are rated high enough to be used to activate the coil of the solenoid.

Thanks This is exactly what I was searching for. I'll let you know if it works as advertised.

Rod did this illustration work for your mower with the battle switch??
