I have a water-cooled Kubota D722-E3 3 cyl. Diesel engine (0.719L 43.88CI 15HP at 3600RPM & 45ft/lbs at 2400RPM). It's 139.1 lbs/63 KG. I've been thinking of what to do with it. So far my ideas are these- 1. Find some piece of equipment with the same engine, and use this one as a replacement or parts motor. 2. Make a wood-chipper with it. 3. Make a framed log splitter with it. 4. Make a framed generator with it. My buddy keeps pushing for this. In either of the last 3, I'd make it skidsteer attachable. I also don't own any of those tools
5. Make some kind of hydraulic pump system to allow non-aux hydraulics skidsteers to use high flow attachments and to power hydraulic hand tools such as saws. 6. Make some type of PTO system to allow it to run various things with a frame around it. This seems interesting. 7. Make a solid axle 4x4 atv of sorts with it. This would be awesome but would take a while. 8. Your own suggestion. I plan to start a land clearing and property maint. business in the future so any thing useful in this field would be great, but I'm open-eared to any cool ideas!
