This Thunderbird TTY45 is a used yarder — also known as a log yarder or skyline yarder — a type of cable logging machine used to extract felled timber from steep or difficult terrain by suspending or dragging logs along a system of cables to a central landing. Thunderbird Forest Equipment is a well-established manufacturer based in the Pacific Northwest, specializing in yarders, processors, and related equipment for the commercial logging industry, and their track-mounted yarders are widely used across North American forestry operations.
This machine is a track yarder, giving it the ability to be repositioned across uneven ground without requiring a separate carrier. It is equipped with a 45-foot tower and a three-guyline configuration, which provides the structural support needed to tension the mainline and haul-back cables during yarding operations. The tower height directly influences the span and lift capacity of the skyline system, with a taller tower generally allowing longer reaches and better log clearance over brush and terrain obstacles.
Included with this yarder is an Eagle carriage with radios, which allows the carriage to be controlled remotely from the landing, enabling the choker setter in the brush to signal the yarder operator for coordinated, efficient log retrieval. The combination of a purpose-built Eagle carriage and integrated radio communication represents a complete, operational yarding setup rather than a bare machine.
The total machine weight is 85,000 pounds, reflecting the robust construction typical of production-class track yarders. This unit is located in Oregon, USA, placing it in the heart of a major timber-producing region with ready access to logging infrastructure and transport.
