OK, I'm constantly headaching over things and always wavering over whether or not I want to keep my truck, what kind of career I want to go into, etc. so I think it's time to do a little fun project for no apparent reason just to get my mind off things. So, I have a '72 Wheel Horse lawn mower. I don't remember the model number, if I remember right I think it's C-100. Any old way, it has a 12hp Kohler that needs rebuilt. Well since we have about 10 other lawn mowers, we don't really need this one at all. So, I'm thinking, ditch the engine or use it for something else, and beef the frame up nice and good and put a smallish turbo diesel engine in there. I've seen lots of lawn tractors with v-8's, etc. but not too many, if any, with diesels. My question is, what kind of engine would work well for this? I saw a few 2 cylinder Onan motors on eBay which might work nice, as long as they're transmission friendly. Most of these were probably used as standalone motors hooked up to generators or otherwise, so that concerns me. I think a 4 cylinder such as a 4BT would be way too big and more work than fun. I'm sure I could use a Kubota engine or something like that, but that would be too easy. I want a little bit of a challenge and something that will put out more than 20hp. Hell if i wanted 20hp I'd just stick a B&S Vanguard V-twin in it. The contingency plan is just to find a 4 cylinder IH Cub Cadet engine, but damn those things cost a lot! My neighbor had to replace the crank in his and it was close to $300 for the crank alone! It's a damn nice motor, though. It runs like a sewing machine. It didn't even move the engine stand at all. That would be a last resort though, I think it would be really fun to build something semi-unique like this. Any input or thoughts? Anybody big into lawn tractor dragging and pulling? I don't think I'll get involved in all that, my main goal is just to build it and enjoy it. While we're on the subject, anyone know anything about David Bradley garden tractors? I've been wanting to restore ours for years!
