Diesel conversion
 

I got an awesome deal on a Kubota D722E 3 cyl diesel engine out of a Woods zero turn. It's complete with wiring harness radiator and mounts. I'm thinking I'm gonna put it in my 100. It looks like it won't be too bad to do. I did some measuring and already looks like I'll have to move the grille shell forward around 5 inches to fit the radiator in. I'm real excited to get started. I've wanted to do something like this for a long time

I fixed your pic. You will actually need to mount the radiator just behind the dash tower like on a 1782 if you have any plans of using attachments that are driven by a PTO. If you not going to use a PTO you can mount the radiator to the front but then you'll need to flip the ring gear or you'll have 3 speeds in reverse and 1 forward.

i thaught about that, I don't plan on using any pto attachments so I'm gonna mount the radiator in the front and flip the ring gear. I have other tractors if I need one with a pto. (Thanks for fixing my pic)

Sounds like an interesting project! Please keep us updated. :beerchug:

If you plan to pull very hard with it, you will have to do something about the lower shaft. Flipping the ring gear makes the gear pull the pinion shaft to the rear. Very much power will pull the snap ring off the front. Just wanted you to know. Probably not a problem unless you weight it down a lot and really pull a load.

I'll keep that in mind thanks didn't think about that. It's good to hear About potential problems I may run into

Putting a 722 into a 100.... will be FULL of potential problems. 722 is larger than the D600/640. You will have a job.

Got the engine running tonight, wanted to make sure it was ok before I tore apart my 100 and it runs great. So I pulled the engine out of the tractor and tried to set the diesel in and the front axle was in the way so I had to cut the welds off the mount and remove it, I figured since the engine fit between the frame rails pretty good it made sense to relocate the axle instead of cutting the frame and stretching it. The axle will be moved forward about 7 inches maybe less. It's setting about an inch too low in the frame which works out well because I won't have to modify the frame rails a whole lot except to put engine mounts on them.

Got the engine hooked up to the clutch today and got the engine and radiator mounted. I was able to cut up the mounts from the woods mower and use them to mount it to the cub I also cut the radiator brackets off the woods mounts and weld them to the cub frame to mount the radiator. First pic is the engine mounts im going to weld them on and cut the bottom edge off same on both sides, second pic is the radiator mount. Looks like I'll be able to move the front axle back 3 or 4 inches it had to be moved to clear the oil pan

interesting project! Please keep us posted.
