350 diesel or 400 diesel

michaelr · Feb 13, 2015

I realize they are a step up from eachother power wise. The 400 being 43HP at the drawbar, and the 350 being 35HP at the drawbar. But what appreciable differences are there between the two which may make one better suited for pulling a shredder and a back blade and perhaps putting a loader on?

Well, the 400 will have more weight, making it better suited for using a blade and loader. The 400 will also have bigger axles to handle more load. The 400 should also have noticeably more torque for lugging. On the flip side, the 350 will be a direct start diesel, the 400 will have the gas start/switch to diesel motor, which may be more up keep to keep 2 fuel tanks filled and all linkage in tune so that it seamlessly switches from one to the other.

My vote is for the 400

cool, did not know the 350 was direct start. Yeah the 400 I am looking at has a dirty gas tank which requires cleaning or replacing, so you are right on about fuel tank upkeep.

You voting on the bigger is better principle?

I understand parts are hard to find for the diesel engine (Continental ?) in the 350. The 350D I ran back in the summer of '64 would run darn near forever on a tank of fuel, but it also did not have much power. We had a loader on it and it was handy to get around with, but mostly we had a Farmhand attachment for picking up 8 hay bales at a time dropped by an accumulator. With the bale carrier and 8 bales, that was a pretty good load on the front, but as I recall, it handled it well. The ranch also had a 450 gas that was the real workhorse for plowing, disking, running the baler and chopper, etc.

We owned a 350D back in the 60's and pulled 3-16 plows with it and a 10" disk. We had pretty good soil for plowing and the 3-16's were all it could handle but it did it. I thought I saw somewhere the diesel had a bit more horsepower than the gas tractor.

350d is 'H' family drive train, the 400 is 'M' family drive train. 350 has a contract by Continentel engine instead of IHC engine- parts can be a bit tricky to find at times but when I had mother's rebuilt they did get found. Tractor is still in the family at older brothers garage along with father's H. IHC sort of replaced the 350 D with the 460D- same H derived drive train but now a IHC designed and made engine. 400D is a 3 valve, extra intake and carburetor and sparkplugs, etc design that has a reputation of head cracks when abused- and also a reputation of often being abused by operator who won't switch back to gasoline and let idle down couple minutes before shutting off. Some parts for MD, 400D, 450D getting a bit hard to find nowadays. The 560 in comparison has 'good' parts availability- that was about the last of the "M" drivetrain family. RN

I have a 350D and the issue other than what others said is the direct start part. They are very hard to start in cold weather. Mine doesn't like to start when the temperature is below 50. Even at 60 degrees it cranks over quite a few times and then really smokes for the first few minutes. I have a completely rebuilt one so it is not because of the thing being worn out. They just didn't have high compression like newer diesels have. They have a manifold heater to heat the incoming air instead of glow plugs. Most of the manifold heaters have burned out and I don't know if you can buy them anywhere. I repaired mine as it was burned out when I got the tractor and so was the one I got that was in a different manifold I bought as mine was broken. I also have an MD which is like the 400D. They has another set of issues. Roger
