Thunderbird TY-90 hoist Serial Number Y-9040 was delivered new to Ober Logging of Carson, Washington on February 28, 1985 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.
