Now for the tractor , Cuz says it is an 8N from 48-52. The 16'' rims are a replacement for the original 19" front wheels. The headlamps are maybe aftermarket. The earlier style had round mounts (think ball & socket)and the later style tractors had a winged back for the headlights to mount in. Also , the dealer sold aftermarket mounts too. These are probably one of these kits.
I should have read all the thread before posting. Yes "red belly" is the moniker for these tractors ! IDK what all the kit would fit but you could install a flat-head V-8 in or on these tractors. I'm sure these would TCB !
I have a buddy that has a "new' red belly and I spent an hour looking at this like it was an Indian artifact. They were able to make a new tractor and keep the spirit of the original intact.
Bill Hagan and all others : Yes , if you are going to buy a toy tractor , it had better say Kubota . These are the best and best built tractors on the planet. This company knows how to make tractors and equipment.
