Alternate serial number avenues for TO 30

"... The serial number is missing. Is there anyplace else on the tractor where I can find the serial # for this tractor?..."

If the original Z129 engine has its serial number on the engine plate, you can apprxomately determine the tractor serial number and year made. I prepared the graph (above) some time ago and posted (here) and the graph is of course also repeated above. If you subtract 240,000 from the engine number, you will be reasonably close to the original tractor serial number. Tractors were built sequentially, but the engines were installed only nominally sequentially as they were randomly selected from a batch of hundreds that were available on the floor.

The biggest thing it tells you is the year of manufacture. Nice to know but does not affect operabiltiy, or price... unless of course it was SN TO60000 or the last one made. etc.

The other was to get a relative year is by the motor serial number which is on a tag behind the plug wires.

There also may be a casting date code on the case under the left side steering column. Though I know these are on the TO-35's I do not think they are on the TO-30's. Someone else will need to clairify.
