Question about GC2310 parts book - which one?

[dragula]

Have a 2006 GC2310 Serial # JRA22637.

Needs parts book. Looking on agcopartsbook.com. They list two books available. One for machines built prior to Serial # JNA25201 and one for machines built after Serial # JNA25201.

My question is - Mine does not start with JNA. It starts with JRA. Does that mean that mine is after the serial number above or before? I mean do I go by the letters or the numbers?

Hope that makes sense.

Thanks for any help!

2nd letter in the serial number is year of manufacture.(O was skipped)

N=04
P=05
R=06
S=07
T=08

Prior to 2005 they used a different serial number pattern,using the first letter as the date of manufacture.
J=00
K=01
L=02
M=03
N=04
as an example mine is N-T####, a unit built in 2004

Thank you for that info!

So I would go for the book that is after serial # JNA25201 since R (06) is after N (04). That makes sense. Thanks again!
