MD

I've taken a liking to the Farmalls now looking to buy a Super M...Does the MD have both injectors and spark plugs...thank you.

Yup.

Thanks,now would that be the best or the worst of two worlds...Any major problems with that set up??

You can't run it on like you a regular gas tractor it only runs on gas to warm it up enough to fire on diesel. Heads cracking were a common occurance because people did't shut them down properly. Other than that pretty neat machines.

The third valve in the head made them more prone to cracking. (It is a fairly complicated design.) It is an ongoing concern to not switch them to diesel too quickly when cold, and that is bad for them.

Also people tend to set diesel timing a bit to high. Also bad.

People want to pull start them directly on diesel. Another bad. Just because it runs doesn't mean you didn't damage it.

People want to start them directly on diesel with heavy batteries. Starter Bendix will fail shortly, and again, no warm up on gas.

After they are in running condition, they go on for ever and will literally run around all day doing small jobs for 5 gallons of diesel.

Compared to other diesels of the time, they were fine. When still warm, they can be fired and driven off in seconds. No glow plugs, no pony motor. I have started mine at -5° F, although it wasn't real easy. You can't say that about a lot of diesels today.

They don't pull as well as a gas engine. It's an old diesel with no turbos.

They can be a bit fussy to start sometimes, due to age. When fairly fresh with a good spark they fire off just fine. Engine parts are out there but are very expensive.

Injection pump parts are basically NLA. There are a few shops out there that still work on them. Used pumps seem to go by on eBay every month or so, but that has been slowing down lately.

I have the same motor in a TD6 dozer & I love it, It has a smith blade on it. Buy IT. Run it on gas before you kill it, All will be good
