Hello. New to this forum. Bought a 4020PS the other day.

A question if I may.

Does anyone know where I can find what year my tractor is based on the S/N? I believe it is toward end to the run for 4020 as i looked at one site that had S/N limits by year but it ended in 2000.

My S/N is 17193737.

I bought the tractor, a rototiller, snow caster that needs a bit of work, hydraulic PTO, 3 point hitch and sleeve hitch adapter. I plan to re-paint and pretty her up but main use is as garden tractor and haul trailer around.

Any thoughts/suggestions very welcome.

Welcome!

I also have a 4020PS that was built after 2000. I was able to get a rough idea of the build date based on the engine serial number. The first character of the Onan/Linamar serial number is the month (E = May on mine for example), and the next 2 digits are the year (01 = 2001 on mine for example).

Now, I'm not sure how far ahead Ingersoll stockpiled engines before installing them into tractors. But I'm guessing maybe a month or two, so that would mean my tractor was probably built sometime mid-2001.
