Hi,

I have $10 gas rototiller that starts like a $10 gas rototiller [meaning not very well]. I have messed with the B&S 3HP engine too many times and it still isn't reliable.

Therefore, especially because the running gear is pretty stout and in good shape , so I thought I'd convert it to electric.  I have an old Century 1HP 110/220V reversible beast of a motor I can use for the project. I have found some articles online about it.

I did find one image online using a very similar rototiller in the conversion

Before I begin I am seeking input/advice [including from my dad the farm boy turned electrical engineer]. Anyone out there tried anything somewhat related to this? 

 

Here's the motor. For scale, it's sitting on a case of Karl Strauss [local San Diego] beer.

 

Interesting, seems easy enough. My only question is "why?" I have a nice Honda rhototiller 8hp brand new runs $2700 but they make decent hand held models for a couple hundred. For the effort involved, you still have a clunky front tined rhototiller. Don't want to be a wet blanket, but at least get an easier to use rear time model. (Even one not running from Craig's list.)

Don't do it

Gasoline is better than electric.

Check the compression. If that's ok then replace or rebuild the carburetor and adjust the timing,

Thanks for the responses. "why" is because I already have the materials [tiller, electric motor, various switches], so there really aren't any additional costs. Also, the area I'll need to till is quite small and very close to a GFCI outlet that can handle the load.  I think the gas engine has a crack that opens when the engine warms up. I've rebuilt the carb, got another carb and rebuilt it, changed gaskets such as the head gasket, and even replaced the exhaust valve.  I do agree that rear tine tillers are easier to use, but for a while I'll have to make do with this front tine model. I did see an non working rear tine tiller on Craigslist today but it is already gone. So, I'll keep an eye out for another one.

I only question if the electric motor will have enough torque.   

WillsC I had questioned that too, but from the reviews I saw with similar motors, they worked well. And this motor is a real beast.
