Super M

[Anonymous-0]

I read the thread a few days ago about whether a M was a super or not. Someone noted that many of the Louiville Super M's did not have live hydraulics as that one didn't. Got me to wondering about whether my '53 SM was a Louiville tractor. It does not have live hydraulics, but is a SM because of disc brakes and the proper carb for a SM. Went to look and there is no SN plate. There is a number stamped on the right rear of the block. Is there any way to know from the numbers on the tractor if it is a Louiville SM? Thanks for replies.

No way to tell that I know of. D.Slater could answer your question with the most authority, as he has made a study of M's in particular.
Bear in mind the 1952 as well as the [b:55419f6ef2][u:55419f6ef2]early[/u:55419f6ef2][/b:55419f6ef2] 1953 super M's were "stage 1" versions and none had live hydraulics. The batteries were not under the seat, but were under the gas tank.
The first "stage 2" super M (1953) was serial number 28175, Illinois built, and number 504802, Louisville. Whether they had live hydraulics or not, they had the battery box under the seat.
Of course, any M or SM could have had live hydraulics added later.

I have a 52 Super M built in Louiville [perfect tag] that has the battery under the seat.

It didn't have live hydraulics just the belly pump.

The "M" motors were 248 cubic inch and the Super M motors were 264 cubic inch. There is a differance in the blocks" length" if my memory serves correct.

I know when guys put the longer block in a "M" there is a 1 1/2 gap between the hood and nose sheet metal.

There shold be some casting #s / dates on the engine block that will help.

I was also told that the Super Ms had bigger bull gears and bearings as well as a bigger clutch. These were the improvments on the week areas of the "Ms" .

Go to the Tractor Pulling section and ask this question of a gentelmen named Chad , he will have the answers your looking for.

If you look at the tractor pictures posted in that early post. Notice on the left side of the clutch housing just above where the hydraulic pipes come out. Notice how the casting has raised bosses there. They were drilled and tapped with bolt holes on most Farmall SM and not on a lot of Louisville ones. Still thats not a fool proof way to tell. One pictured in the other post is a Farmall serial # and I can't see any holes in the picture. Back to the bosses on the clutch housing. Stage 1 SM don't have them on the housing and stage 2 SM do. No way to tell for sure the plant without the serial tag. If the engine is original the serial # on it can tell the month tractor was built. Hope this goes through, I posted about the difference in stage 2 tractors today and the post wouldn't go through.
