year of manufacture??

OK, I have a Gravely Model 915136 (2548 ZT XL) Serial number is: 000516.

Can't seem to find any dates for this serial number at Gravels website.

Anyone know?

What are the engine numbers. Sometimes, that will give a clue.

I'm curious, why is it relevant?

Well, I am going to sell it and wanted to know the year.

I didn't think about the engine serial number, thanks...
