Super M???

Hello,

A friend of mine called up and asked me to help him advertise his tractor for sale. I went to look at the tractor, and try to figure out just exactly what it was that he had. To me, it apppears to be a Farmall M. He thinks it is a Super M because when he rebuilt the engine, the pistons from an M were too small, and he had to order pistons that were 1/8" (?) bigger in diameter. The pistons that worked, were listed as being for a Super M. So far, I have found out that:

* A Super M first came out in 1951. His serial number is 225805X1. The archive list does not have M in the Farmall section, so the year of his tractor is still unknown, and cannot help at this point.

* Looking in the Nebraska Tractor Tests, it appears that the Super M medallion is more squarish than the previous M's. This indicates that he may have an M. The book also mentioned that the pistons were indeed a bit larger in a Super M.

* The white round decal on his does not say Super M. The photo section of YTMag has some Super M's but they all say so on the decal.

* My friend thought that the power steering also made it a Super M. I believe that the Behlen unit was aftermarket, but am not certain of this.

Although I have a Farmall H, I mostly know the green brands, and am in unfamiliar territory here. Could anybody shed some light on what he may have?

Thank you,
Greg

Its a M tractor, serial # is for a 1950 year. Piston and sleeve sets were made to increase standard bore form 3-7/8 to 4 inch, very common.

Thank you!

Also, the serial number tag for the M will have a prefix of FBK. The prefix for a Super M will be SM.

Easy way to tell between the m and super m is that the super m has the disk brakes like the later number series tractors while the m had the band brakes with a flat surfaces shround covering the brakes. According to the brakes in the picture, its an m.

Sure enough! FBK. Thank you!

That's interesting. Never would have picked up on that! Thank you.
