I bought a John Deere GS30 WB 36" cut with a blown 13hp kohler command Pro engine on it. Well, I bought a Kawasaki FB460v to put on it but found that since I don't have the voltage regulator and capacitor for the kawasaki, I can't get my electric clutch to work. The parts are expensive and I just don't have time to tinker with it until it works so I have decided to look for a replacement engine. I'm keeping my eye out on craigslist and ebay but here is my question... What engines will bolt right up to my mower and have the same electrical components as the original engine that was on it. The kohler had just a three prong voltage regulator. Can I get any kohler engine between 13-15 hp? Only kohler command pro...kohler command... What Are my options? I really want something that I can just bolt on, hook up the few wires and go. I don't want to worry about rewiring or anything like that unless I have the right information so that I know what I'm doing. Here are the original engine specs: Model- CV13T Spec No- 21520 Displ (cc) 398 Serial- 2831303131 Thanks so much for any help!
