You really can't tell buy the serial #.
Tractors are not like cars, year is when the tractor is sold not when it's manufactured.
Year of tractor is somewhat irrelevant.
That model was manufactured from 2006 to 2012, and a 2012 will be the same build as a 2006.
What matters on tractors is the hours.
A 2006 with 200 hours is worth more than a 2012 with 400 hours.
If you really need to know what "year it is, go to a dealer and they might be able to tell you when it was sold.
