Big Dog and Chicken Wing,
Thanks for answering so quickly.
The nose is rounded with the grille a mesh type material. It is painted white, not sure if it is the original color because the man my husband bought it from had put a so-called paint job on it.
As far as the color of the tractor, it is red.
The part number under the carb is 251341R7
Thanks for the site with the pictures and for all your help.
