Roland, Harry:
You all have spurred me on to investigate S/N as an index to the year of manufacture. I collated the following from two sources (1) Parts Lookup (wherever a "-" separates the span), and (2) a compilation, index & cross reference of model numbers dating to 1991 that I found stashed on my hard drive, no doubt downloaded from this site (wherever "to" separates the span). It was difficult to make heads or tails out of some of the listings from Parts Lookup.
I tried to upload the second source, but the file was far too large.
Since "tabs" don't seem to translate well from ASCII files to HTML or however this site is coded, I have emphasized the Hood numbers.
From Matt's earlier comment, I'm guessing the tractors manufactured in 1990-91 came with yellow decks; but it seems to me that the 1990-91 era is the most likely candidate for when my 44C deck became available for purchase.
