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.
This is the switch/relay i was talking about... Will it work?

On a side note, If I use the Battle Switch, I obviously wire it to the Solenoid, seeing that I can not find the Amp rating or pull of a standard Ford style solenoid will the 10 amps be enough?
RichMR2,
Thank you for the diagram. I am thinking I need to run a battle switch to the starter solenoid, then wire the solenoid to the starter?
"Thank you for the diagram. I am thinking I need to run a battle switch to the starter solenoid, then wire the solenoid to the starter?"
This sounds correct. Do you own an ammeter? If you haven't disassembled the existing mower completely yet, you could measure the amps at the solenoid while starting the motor to make sure it is drawing less than 10 amps.
Does it start with a battery or a 120VAC plug today? If a battery, it is almost certainly less than 10 amps draw.

Why not use a standard automotive relay 12v coil spdt 30 amp continuous rating. They can handle twice that for several seconds. Yes I'm watching for wiki material
I have been away from the keyboard a few days but I'm back now.
@ Alan 90 percent of meters out there under 300 bucks are fused at 10 amps max for measuring current load even the nicer "ideal" "snap on" and "fluke" brand meters its a standard limitation. Just wouldn't want someone to let the magic smoke out of their meter... It needs it after all lol
Just out of curiousity why use a coil? A coil is to supply ignition spark, I need to engage a starter?
Last summer my John Deere walk behind transmission took a crap. I can't complain though as it lasted me 26 years
I seen some robotic mowers on the net and it really only takes a hand full of parts to convert a mower to RC control.
I plan on using a regular mower, maybe if I had that machine shop you have I would go from scratch too
I was wondering how you plan on turning the mower as your wheels looked fixed?
I know one of the problem RC controlled mowers have is they don't run true.

Differential drive just like a skid steer, if you have turf tires it will not harm the grass
