I will put up my 1968 Wheel horse Commando 8 that was transformed into the diesel powered Autism Horse. Started with a nice solid tractor and mower deck, mowed with her as is for the first year I owned her. I wanted to custom decal the tractor for Autism Awareness as I myself am on the autism spectrum. Local sources were very expensive and I was just pricing a decal for the hood. The owner of Redo Your Horse donated the custom decals, including fender stripes to the project(Thanks!!!) I have always prefered diesel power over gas, but all the factory diesel GT's are big, way to big for our small yard. So I started searching for a genuine Yanmar air cooled instead of rolling the dice on a clone of unknown quality. I picked up a surplus Yanmar L70AE from a military genset off ebay, came with intake heater, electric start(24vt) and recoil starter. I also purchased a 12vt starter, 12vt stator charging kit for under the flywheel and a tapered shaft to 1" keyed shaft adapter. I mounted the diesel in the tractor, relocated the battery to under the seat and added a fuel return line bung to the factory fuel tank. I reused the factory cast iron 3 groove pulley from the original Kohler gas engine. She runs flawlessly and uses a fraction of the fuel the gas engine did(and it was pretty good on gas as it was). The engine came with an intake heater, like found on Cummins powered Dodge pickups, I have it set up with a push button on the dash and I reused the original generator light as a preheater indicator. The final touch added thus far was one of Glen Petit's cast resin horse head hood ornaments that I painted to look like chome. The tractor is an everyday worker, mowing grass and pushing snow in the winter time. Along with being my "butt buggy" at shows and pulling my friend on his sulkey. Many times at shows, folks look at the tractor cock eyed as when the diesel idles, it sounds much like a Kohler with a bad rod knock. Its only when I either do a quick throttle up and roll coal or stop and open the hood do they realize the tractor has a diesel engine.
