Welcome to the forum! 


What tractor are you converting and what Kubota are you using?

Welcome to the forum.

 Are you sure the flywheel end of the engine is going to give you the proper rotation. Having done a half dozen diesel conversion I can tell you this is very important. Some more facts about your engine and tractor would be helpful. Photos would be wonderful. Most of the time the front end of the engine is used to drive the tractor.

You are going to have an adapter plate machined. Pretty sure as Cvans stated you will want the engine in the other way. The flywheel on my cub with the kubota diesel faces the front of the tractor. If you install it with the flywheel facing the back of the tractor you will end up with 3 reverse gears and one forward.

If this cub drives off the crank end stock then it does need to drive off the kubota flywheel. But if like most cubs it drives off stock flywheel so it would then have to connect to water pump end of the kubota.

You will need to flip the diff first off so you will have the correct rotation. The go to Zak kerbers web site or midwest super cub, they have what your looking for to get the clutch to the flywheel.

Maybe i can help. I dont have any pictures on me currently so ill try to explain the best i can. Theres a diesel garden tractor pulling page on facebook you should look it up. Now first off you will need to extend the frame about 6 inches to allow for a radiator. You could run the front crank connected to the driveline but if you plan on running performance mods then its a good idea to run it off the flywheel. Midwest super cub and zack kerber sell the clutch hubs. You will also need to get a heavier clutch spring and atleast a 5 puck clutch disc from midwest.I will tell you now that STOCK PARTS WILL NOT WORK!! You will also need to beef up your transmission. That would include axles and carriers, gears,and a hardened shaft. If you need to you can run a 1' inch axle setup fine spline carrier.
