This Thunderbird TTY6150 is a yarder — sometimes called a logging yarder or highlead yarder — a type of cable logging machine used to extract felled timber from steep or otherwise difficult terrain by hauling logs along suspended or ground-level cable systems. Thunderbird Forest Equipment is a well-established Canadian manufacturer specialising in cable yarding and logging equipment, serving the forest industry across North America and beyond.
This 1998 machine has undergone an extensive programme of rebuilding and refurbishment, with the seller's notes detailing work carried out across virtually every major system. The spar has been rebuilt, and a new skyline head has been fitted. All drums have received new bearings and shafts, and new mainline shiv bearings have been installed. The lines are described as all new with the exception of the haul-back line. The water brakes have been rebuilt, and the cab wiring has been completely redone.
Additional work includes sandblasting and full repainting of the machine. At the time the listing photographs were taken, a rebuilt motor was in the process of being installed, indicating that the powertrain refurbishment was either recently completed or underway.
Located in Oregon, USA, this used yarder represents a comprehensively reconditioned unit with significant mechanical investment across its drums, braking system, cable hardware, and structural components.
