Timberking Rubber-Tired Harvester New on the market is the Timberking TK856, a rubbertired, 6-wheel drive harvester. The TK856 is designed to give the logger more mobility to get to the next worksite as quickly as possible with a minimum of expense. With its rubber-tired chassis, the TK856 allows for easier movement in the woods with minimal disturbance to the forest floor. The articulating frame has a tight turning radius, and soil scuffing is not noticeable as compared to turning a track machine in the woods. The TK856 comes to market with a track record not typical in a new machine build, because it incorporates proven components from Timberking forwarders, rubber-tired feller bunchers and track harvesters. It features the hydrostatic propulsion system incorporated into countless rubber-tired feller bunchers, the ability to travel between 0 and 12 mph and the CAT 3126 DITA engine and high-efficiency cooling package. The torque curve allows this 200 hp (149 kW) unit to operate at an optimum rpm, while providing good fuel economy. For more, visit
