Dude, I had the same question, I had just bought a 742 the other day. I sent the serial number in an email to Bobcat asking to tell me year of manufacture and about 5 min. later I got the answer, mine is an 1989. I payed 75 hundred for it, it is clean and came with four brand new 10X16.5's and a trailer, I didn't think I could pass it up. The 742 is lp gas powered so I can run inside buildings if I wanted to. I am thinking of putting an ad in the local paper, something like Bobcat for hire. I am always getting into something so I figured it would come in handy around the shop.
