Thunderbird TY-90 Serial Number Y-9040 was delivered new to Ober Logging of Carson, Washington on February 28, 1985 and
mounted on a Berger self-propelled carrier with 100’ tower. Later, Ross re-aquired the machine and pulled the TY-90 hoist
off the Berger and put it on a Skagit T-100 SP carrier. In March of 1994 it was purchased by Nygaard Logging of
Warrenton Oregon. Here can see this yarder in 2004, mounted on the Skagit T-100 Self-Propelled tower/carrier painted
and lettered to match.
