Vintage Late 1970's Ertl John Deere 5020 Diesel Tractor 1/16 For Sale

This is for a 5020 John Deere 1/16 die-cast toy tractor by Ertl. I believe this is from the late 1970's in the original box. Tractor shows quite a bit of shelf dust and box has some wear on some of the corners, see pictures. This has always been in the box. I could not see a smoke stack with this but it may be buried in the box?? I am selling other tractors from the same collector and will combine shipping if I can.
