Farmall M propane conversion

Anonymous-0 · Apr 29, 2009

Hello. I am going to look at a Farmall M tractor that is on propane and is a wide front end. I understand that they were not mfg that way from the factory, is that correct? What is involved in the conversion, ie parts, ect? was this a common coversion? Is the wide front end less common? It does not run right now so what is the first step? Got lots of questions about this so THANKS FOR ALL YOUR HELP

You say, Not made that way from the factory. Which do you mean. No wide front, not equipment for LP fuel, or NOT LP fuel and wide front end.I am pretty sure though NOT a IH expert that M's were available set-up for LP from the factory. LP as a fuel has a bad rep. but I have owned a LP fueled combine for the last 12 years and LOVE IT. NO fuel system/ carb. problem after storage in the fall. A hot battery and turn on the fuel at the tank and the engine starts and runs as if it had been running all winter. Yes there are fueling issue. They are NOT that bad UNLESS you have an LP supplier who is clueless about the MOTOR fuel side of his industry. Most LP supplier sadly only understand the heating fuel side. I would love to find a LP fuel tractor. I would buy it and leave it on LP and USE IT.

If your propane provider is clueless about his fuel product, find a forklift service outfit in your community. Usually they will provide "house calls". We have a forklift and it is propane fueled. Our forklift people do come to the house. CC

Own quite a few LPs. Did own a super M LP for a while. That one was a real basket case and I traded it off.

Don"t know for sure about the straight M"s but the supers were sent to Oklohoma to be converted for IH. This was a IH endorsed deal and the parts show up in the parts book for this conversion. Don"t remember about the M but a proper LP tractor will have it"s own head and intake manifold. Head is for higher compression and the manifold doesn"t have the heat sync between the exhaust and intake.

If it is factory the tag should hav LP stamped on it if I remember right. There is also a code that was for LP"s but I don"t know those codes that well.

If it is the factory WF it should have a casting in the center that is reversible. Yes the WFs are quite rare in my neck of the woods at least.

Good luck

youre right I think no M was mfg as a LP tractor. the SM were, as were 400 450 etc. To me, LP is the only gas tractor I want. I don't even look at anything else. LP is the easiest to maintain of any tractor made.

Stevie, The M series were not Factory LP. Only Gas, Diesel, or Distalate. All Ms that have LP on them are conversions. Usually done at the farms were the tractors lived. These are usually called "Field Conversions"
The first tractors in the row crop series were the Super Ms. Though the standard or wheatland versions had had LP for a few yrs prior.
The wide front-end was an opition for the row crop tractors, so was the single front, AKA "Cotton front" and the two tire, V shape front usually refered to as a tricyle front. Front end could be changed out for various cropping practices. sometimes 3 or4 times a yr or even more,
First things first on getting it started, Check to make sure the motor isn't stuck, be sure you have a good batt. Check points, got fire, Good plug wires. and good clean properly gapped plugs,
Add a little LP to tank if empty or the tank may have a little still in it.leave the LP valves off turn over the motor as if to start, then open the vapor valve it should start. If you have ?s hollar at me 512-577-3837
Later,

There are so many people on here who are misinformed and they mis inform others.If you don't know what the hell you are talking about keep quiet. 500 SMTA's were sent to Lubbock Tx to be converted. They went back to IH and were then sold from there. LP Conversions were done everywhere to thousands of tractors. The first LP's were the 400's. The first High Compression heads were added at the factory about half way thru the first of the 400's production run.
A lot of conversions pushed LP thru the bottom of the gasoline carb,so you don't even need a carb. Eliminate the LP stuff,add a gasoline tank and you are good to go.It sure isn't rocket science.
