Hello,

I recently got a 1550 gas and would like some information on the model number and the number after the serial number.

The plate at the bottom of the dash is Model Number 255-21287 Serial Number 181029-504 from what I read at the library it was manufactured in late 66 but I can't find anything on the model number. I ordered a tractor data book off the internet and it only has the serial numbers produced for the 1550 by year.

Any help would be appreciated.

Thanks,
Jeff
