Yeah cheers for the pics, quite a collection. D9D is the first of the series with a single air cleaner; later ones had dual aircleaners.
Is that a late IH TD18 with the twin exhaust pipes, or a early TD20 ?? Seems tidy; still run ? And looks like a alliis HD20 hidden in there too.
Little LeT model D scoop goes good behind a D4 or HD5 !
Looks like a TD18-182 series, the original horizontal muffler may have rotted away and they went back to twin stacks........there was a fella out of Wetaskiwin AB that started off his business picking up abandoned equipment after the miltary's Alaska highway project......saw a TD18 182 in near perfect condition on this widows yard that had his stickers all over it......
Thats some nice work your doing up there......hope you have a good winter.......
