I have two MM tractors here that are painted blue. They were New York State highway tractors used mostly for mowing. I know other states bought MM tractors and had them painted their preferred color. Roger

OL-TIMER,that flat spot IS a brass tag. Take some steel wool or real fine sandpaper or even some Brasso and clean it up and you should find the date codes (sometimes they are really small). On a couple of mine they are numbers that don't make sense. I'm going to go out on a limb, but I think a pretty strong one, and say your engine is number 408180. The serial numbers for 1942 "R"'s are 407951-408825 inclusive and the engine numbers are a little higher due to the fact that some were used in power units. I think we've narrowed it down enough that your tractor is a late '41 or early '42 and the 408 one hundreds are in the early 1942 serial range. There are a couple serial number ranges that your RTU could fall into and that would be 408074-408120 and 408125-408154 inclusive. There is another run of RTU's with serials 408159-408251. I'm sure your tractor would fall into one of these ranges. The tractor numbers can lag the engine numbers from a few to quite a few, say 100, or even more. I've never seen an earlier "R" with anything but an aluminum engine or tractor tag. If you get into your engine there are a few things that changed so you can help corroborate serial ranges. There may even be a date on the back side of the main or rod bearings. I may have an extra throttle body for a TSX-36, I'd have to look. Hope this helps. Jim

OL-TIMER,

To further try to help you, do you believe you have the original carburetor? You should have a TSX-36 and that will be stamped on a brass tag on the back of the carb. It will also have a date code such as 9 43 or 4 41. You know that your tractor had to be made after that date. Also, does your tractor have electrics? If so are they Delco-Remy and do you believe them to be original to your tractor? If so and they have the original tags (starter and generator)the serial number is a date code and can be deciphered. Once again, the tractor had to be made after the individual components. Hope this helps.

Jim

Starter is Delco-Remy 1107025 1K15 . You guys are super Anything else just let me know Thanks.

OL-TIMER,

Yes, we are super! (Just kidding) Anyway, you are in luck as that is probably the original starter, as the model 1107025 is the original for the "R"'s of that vintage. The starter was made on Nov. 15, 1941, so your tractor was made after that, probably a late '41 or early '42 (I still have my dad's late '41 RTU). You may be able to read the carb tag with the carb on by using a light and mirror after reaching around and cleaning the tag with a rag soaked in laquer thinner or gas etc., or maybe just as easy to just take carb off. Hope this helps. Jim

OK BMG1 it has the curved brake pedals 3 adjuster nuts A straight 32 1/2 Inch drawbar.AS for any more numbers no luck yet. JLM the tag is metal. that is why all the rust has ate all the numbers off. Is a steel tag odd? You didnt mention one. Thanks again

OL-TIMER,
Based on the drawbar dimension your R should be in the 1940 to 1942 range. This assumes the drawbar is original to the tractor. That helps narrow it down quite a bit. Engine serial numbers for those years were 402229-408826. If you can read the digit right in front or your "180" it will narrow it down to the exact year. As far as the steel tag goes my first guess would be they may have used steel tags during the war years due to materials rationing. But I don't know this for a fact. Just a guess on my part.

from you information it is between a 1941 and a 1946 the engine serial # will narrow it farther

Magneto ignition was factory equipped on model R tractors up through mid 1946 (serial 414455). The brakes changed in 1947 so we know yours is older than that and will have the early brake pedals that are not straight but somewhat hooked. The rear axle housings will have large adjuster nuts for adjusting the brakes. If you've had it apart to the clutch in 1946 they went to a 9" clutch. It was an 8" version prior to 1946. The drawbar changed in 1943. Prior to 1943 the drawbar was a straight 32-1/8" long part. After that it went to 35-5/8" straight up through 1948. Those appear to be the differences for magneto equipped tractors (after 3-piece RT fuel tank).

If you can read more numbers on the engine tag it would sure help especially the first 3 digits which should be 405### to 416### for 1941 through 1946 production EE engines. Sometimes you can see what was stamped in the tag if you remove the tag and inspect the back side. I've also had luck by shining a bright light across the tag with low levels of background light. This usually illuminates the highs and the numbers will appear as dark areas.

I hope this helps.

Brian

1. Usually I can read the SN tags at night using a flashlight. Sight the tag straight on and hold the light from the side. Try different angles with your head and the light. Wipe the tag then try again with the light.

2. Annother method is to clean the tag then wipe the tag with black shoe polish paste, then wipe the excess off leaving the imprinted numbers blackened with shoe polish.

3. Another hint that will help us. Is the engine tag brass or aluminum?

4. You say the chassis tag is missing. Are you sure you are looking in the right place?

Assuming it has the original engine, and the tag is still on it, there are a couple guys on this board regularly who can tell you what year the engine was made.

otherwise, Clint's questions can probably get us within 2-3 years of its 'birth' at least.

I dont know if you can actually give it a true Serial # tag I would not thinkso but what do I know now to help Identify the year does it have a Mag or Distributoer, flat 3 piece gas tank or rounded 2 piece, and describe the seat bracket in 1948 thry chencged to a more suspension type seat if yours has the hood hinges it is before a 1949 model we should be able to narrow it down more with taht info
