I have a 1992 craftsman limited edition gt6000 tractor with the number 18 on the lower side of the hood. Not checkered flags and indy 500 like I've seen elsewhere.
On the top side of the hood is a picture of an indy car with indy 500 next to it.
Craftsman model# 917.250910
Engine is horizontal
Engine model is 422437
Type is 1278 01
Code is 92010612
Made 6/01/92
I'm wondering if this is the tractor danny sullivan used at indy
