Trying to figure out if my Model B has the original motor.  Given the following numbers, can you please tell me a little bit about my tractor? It has electric start and PTO, but these may have been added later.  Also, what engine is this, the early one or the latter with higher HP?

Engine: (right side) AM2916-13, (upside down, on block) 11-25

Transmission: B65483

Tube: 12-20

Hopefully I provided all the information needed for an identification.  Thank you for your help!

so its a 1943. If you look at the vertical flange on left side of motor at the bell housing you  can get the motor number. You should have the CE motor which is 125 cubic inch and was a little stronger than the original BE motors prior to 1940.

The serial number list posted is from ytmag and has an error on 1943 it should read 64501 since the numbers in 1943 were from 64501 to 65501.  So your serial number would say it is a 1943, however your casting number from the block says the engine is from 1941.  Many of these old tractors have had engine transplants though.  There should be a serial number stamped on your engine too that would be a better indication of its year of manufacture.  Here is a site that has the information you need:
