I am going to pick up a farmall MD in the morning. I was told the only thing wrong with it is that it will not start. The guy i'm getting it from told me that he used it all day to blade his driveway. Befor he could get it into his shed it died on him. I tried to ask him if he was just warming it up to switch to diesel (it was april in minnesota and a few hours sitting it would need to warm up first.) The reason I think it quit on gas for him is because he is really close to the shed but not strait on with the door, kinda off to the side. Like a person would do who wants to keep the entrance clear to his shed. Also the bucket was not let down and was in a position where one might leave it if he was planning to put it away later. It is important for me to know if he was running on diesel and stopped it there and was going to put it away later for the night. He says that he cannot get it to start on gas. Thats why i think it died on him while warming it up. I have never driven one before but it seams to me that if it wont start on gas there would be a problume on the gas side like no spark or no gas. So im hoping that the diesel side is good. He dosent know alot about them. Dosent even know where to look for the serial number. So for i'm thinking that is a good sign. I am under the impression that i can switch the rack to diesel mode and pull it till she starts. He has not tried this. So im praying that is how we can get it going. Is there any chance that the diesel went out and the gas went out at the same time? If it died on diesel (which i don't think it did) and then would not start in gas just seams to puzzel me as one would think that both the diesel and the gas part of the engine would not go out at the same time. What would make it die on diesel and then not start on gas? ANY ideas? thanx ahead of time Jonnnny2006

It'd be a good idea to find out EXACTLY what was going on when it "died" on him. If he'd been really using it all day, and it died while hot before he'd had a chance to cool it down, there's good chance that it caused problems in the head- either cracked or warped starting valves. If you can get it going these should show up. The MD will be good on fuel economy but if you have to start putting alot of work into the engine, the higher cost will eat up any potential fuel savings pretty fast. Hopefully it's nothing serious- good luck!

if it lost its spark i dont think it will start on ither side becuase i think the md runs off of spark plugs but not owning a md i could not give you very acurate advise

No diesel engine runs of a spark plug. When these are switched to diesel the electric current is stopped at the same time you throw the lever to switch over to diesel. All diesel is ignited by compression rather than electrical spark.

By chance are the gas tank and fuel tank full? Armand P.S. are the shutoff valves open at the bottom of the fuel tanks open and sediment bowels clean?

I will post my findings tommarow. when i get there i will have him pull me on the md in diesel mode and hopfully she go. Thanks for all the good advise so far. I have 3 farmalls allready and the md will be the biggest one i have, the 1953 stage 2 super h has almost the same power. but the diesel will get better fuel economy. my 43 h runs real good it was in rough shape when i got it. but i got her purring again. i have a 44 h with a 6foot mower and it ran real rough so i adjusted the valve tappets and that helped. the guy befor me dint know he had a bad plug wire and ran it like that for who knows how long. any way i cleaned the carb and put a quart of tranny fluid in the full gas tank. put new plugs and wires adjusted the points and timing. drove it on the road and whent up hills and it started to chug out black carbon build up and was burnimg the tranny oil. every time after it chuged out black stuff it ran better and better. i ran that tank almost gone and filled up with fresh gas and it started to run better and better. The guy had ran it so long with a dead piston it gummed up the exaust valve and that let to a miss. now it is running almost perfectly. It is nice if you can get by without taking it all apart. That H is a X1 gasser. lots of power! 135 lbs compression across the board. now it has lots of snort. it would put up a good fight with my stage 2 super h well gotta go. I will let you know what happens with my md. I think we will get it running right there as to make it easyer to load. i will figure out the gas problume when i get her to my farm.

I am not going to try and trouble-shoot the problem but, yes, you can pull start in diesel mode. It is how the auctioneer crew started my 650D. There was nothing wrong with the gas side. They just thought it would be easier to start it with a chain. The battery may have been weak or the starting tank was empty. Can't remember. That was the last time it was ever pull started.
