Dwight Garrett was building machines from army surplus parts after WW2 ended.
there were many proto types of a log moving device but these are the start of mass production. These early versions had axels from 2 1/2 ton GI trucks. Ford truck transmissions and chioce of ford gas 4 cyl or wisconsin aircooled V 4's.
This old beast was Sams log skidder. It is a Wagner built between 55 and 59. These were some of the first rubber tire yarding machines built. This wagner had 2 steering wheels and you could swivel the seat and drive either direction. It had a blade on back to drop and anchor while winching as well as push material. You can see that it has loader type tires because at this time the light weight flotation tire had not been developed yet.. It was in pretty rough shape so it went to the scrap yard along with the cat grader in next pic.
check out the Vannatta bros logging museum. I offered it to them but they have a couple now. they did use my pic though. I dont think they had a twin steer like this one.

this was sams IH TD 20 that I bought from his famaily after he passed.. I had asked Sam a few times what he going to do with that old cat and he would tell me, got some property up on the res and got to clear some trees someday.. Sam was 82.
Sam was putting his pants on and heading to work the morning he left us..
