Here is a link to some of the pics to the build of the great Cub-Ota. The installation of a Kubota Z-600 twin cylinder watercooled diesel that makes around 14 hp from what I have read. Make sure you follow them all the way to the bottom of the page and click on the "Older Posts" to see the finished rig.

She is all done and has been out pushing snow for 2 days now. I ended up turning the clutch around so that the driver is connected to the tranny and the shaft to the flywheel on the engine. There was some machining needed to do this. I used the stock clutch hanger after trimming it down some. I have some pics of the adapters that I made but have not loaded them yet. I think I am going to redesign the driveline to use a kubota clutch and pressure plate or I will have to make my own heavy duty clutch using aftermarket pieces. This has quickly become my weak link.
I also stilll need to figure out what I am going to use for a fuel tank. At the moment the stock tank is mounted on the fron of the tractor since it clears the plow and seems to work alright but it is definately ugly. I will be making a tank or finding another tank from something that I can fit somewhere that it will look better. For now this is all I have.
There are also pictures of my Cummins powered wrangler too. . . . . If you are interested. The Jeep was sold and now resides in Arlington Texas somewhere last I heard.
Any questions just ask.
