My tag says Tractor number: G525268 Model: TC45s so maybe mine is 2002. I have the hood with the 2 square headlight lens. I bought the tractor used and the person didn't have the paper work but thought it was 2000 or 2001, they bought it new. From what I have found out so far, Is that differant models like the tc45 tc45a tc45d all had differant headlights from year to year. I haven't found a tc45s yet so don't know what that means for my tractor. I know from looking at the tractor specs on tractor data that the tc35 ,tc40, and tc45 all use the same chassis. Hope this helps. I'm looking for the year so i can buy a repair manual for the right tractor and to buy parts should i need them. Also i've read some post about super-steer, how can i tell if mine has that. Thanks
