From what we see, you might find the serial # plate on the right frame rail, between the axle housing and the right foot rest. Later models used the bellhousing. You should hunt around and scrape a little to find original paint, it should be orange, and the center strip on the grill should be about 3/4&amp;quot; wide. If this tractor is this early, there will be considerable difference from later years, if you know what to look for. You may want to call Landis Zimmerman, he can be very helpful with information, manuals, data, and parts. PH 717-738-2573
Having found this tractor in a woodlot, there is good possibility the serial plate has been knocked off, and lost. That happened alot.
