Yup, that's a YT or LT alright. I have a YT12 I got free from my neighbor. Bunch of us YT/LT fans are on this forum / thread all the time:

Yup - it's an LT16, mid 80's vintage. I got it last year off of craig's list to run as a snowblower - made a cab and it worked pretty good. I mowed with it all summer (all of 3 times, thanks to our drought). I had to put in a new disk drive, but all else seems well. It's now all set up in snow mode again, and it's flurrying...
