One of my students wants to make a clock for his uncle who owns a
Farmall Cub tractor. We have not had much luck finding a good drawing
to convert to a CAD drawing.

If anyone has a good line drawing of this tractor and can share it
with us we will appreciate your help. CAD format great, DWG, IGS, DXF
and so on. JPG or other pic;ture useful also.

Did you try http://images.google.com/images?q=Farmall+Cub ?
Seem to be numerous ok jpg's and gif's. The line drawing
on 2nd page, http://www.esnarf.com/2160a.jpg is a bit ragged
and has a "strip of paper placed across scanner to prevent
image copying" but perhaps esnarf will sell a copy.
