[AT] Allis Chalmers Crawler HD-3

[carl gogol]

Any of the list's crawler people have any experience with an HD-3?  Since 
musch of the tractor is the same as a D-14/15 I assume that it has similar 
reliability tendencies.  but what about the track system, are parts 
available?  Does the track have a problem with staying on or anything else 
unusual?  Would appreciate any info you might want to share.
