Where is the serial number tag located on a 180? The engine serial tag is visible and in good shape, but don’t see one for the tractor itself. The tractor was painted once before so I’m wondering if the tag has been lost?
Trying to figure out the build date and track down some history on it

Tractor data just says “Front of the torque housing”

It’s not a tag. It’s stamped

Look at the edge of the torque housing right behind the engine. On my 220 it's on left side.

left side, on Torque Tube/clutch housing. It's stamped into the casting.

About 1 inch behind here the left side frame meets the bellhousing. The numbers will be up and down starting at the top with 180-XXXX- D or G.

Thanks, saw that but wondered if it was just a casting number
