Actually, nearly every kind of truck has been used in the woods and some such as Kenworth, Peterbilt, and Pacific have a heritage from the Pacific Nothwest timber industry.

Bulldozers Loggers aren't loggers unless they have bulldozers and you won't be disappointed, because we have lots of them along with a few pictures of the neighbors dozers.

Dozers are the classic all purpose machine.
One used to never see a logging side without one, but in recent years their popularity has declined. The Iron Museum page features yarders, excavators, road graders, rock loaders and related machinery as well as still more log loaders and bulldozers. Find on this page a wide variety of machines and a rich selection of photographs. The text is considerable with pictures throughout so stay with it to the end even if you want to see only the pictures. For the index of over 20 machines push the thumbnail photo on the left.
