Designed with input from operators, equipment dealers and other forestry professionals in the Pacific Northwest, Barko processors are purpose-built to provide several performance advantages over the competitive equipment commonly used for timber processing tasks. An enhanced hydraulic system allows for optimal picking, delimbing, cutting to length, and stacking. Offering exceptional horsepower, swing torque and tractive effort, the 270B processor features a dangle head boom configuration for delimbing and cut-to-length harvesting. Engine The 270B is powered by a 225-HP Cummins QSB6.7 Tier 4 Final diesel engine with SCR after treatment. The unit includes a 36-inch-diameter auto reversing fan with automatic temperature control, and heavy-duty extreme cooling engine package. IQAN Control System IQAN electrohydraulic control system is specifically designed for Barko machines, with hydraulics tailored for harvesting applications. IQAN offers infinite variable control, including programmable settings for individual operators. IQAN-MD4 Display System information and machine diagnostics are conveyed on a convenient Parker IQAN-MD4 cab touchscreen display. Hydraulic Power The hydraulic system on the 270B ensures power is always available, allowing operators to instantaneously shift from function to function with no delayed reactions like with other machines. •Load sensing hydraulics automatically adjust performance according to the load. •Delivers more hydraulic horsepower to the attachment through exceptional pressure and flow. •A dedicated attachment pump runs the dangle head without robbing flow from the machine for other functions. Undercarriage & Tracks The D7 undercarriage with 8.5-inch chain pitch offers ground clearance of 29.5 inches and track width of 11 feet, 5.5 inches with 700-mm pads. Longer tracks also contribute to firm, stable footing. Drawbar Pull The 270B delivers an impressive drawbar pull of 66,700 foot-pounds, giving it the ability to handle steep hills and rough terrain with ease. Swing Dual swing-drives provide continuous rotation and high swing torque of 58,384 foot-pounds. The machine features a heavy-duty, oversized swing bearing and offers excellent reach with its dangle head boom configuration. Forward-Sliding Cab A patented, forward-sliding cab design allows for easier service access to the main electrical panel and engine compartment. Gull Wing Door A large, hydraulically opening gull wing door offers direct access to the engine and components. Spanning nearly the full length of the machine, the gull wing serves as a working platform, complete with a slip-resistant walking surface. Storage The 270B features a storage tray, two storage areas on the door, and space for a lunch box inside the cab, along with two additional storage areas outside the cab. Operator Cab Large side door entry provides easy access to the comfortable cab, which offers excellent visibility, a heated air-ride seat, cup holder, dome light, radio with MP3 auxiliary, AM/FM/WB, USB, XM-ready and Bluetooth, and even a coat hanger. Visibility A 1.25-inch polycarbonate window provides added safety on harvesting jobs, while an air knife system keeps the front window and oversized skylight clear of debris. A sliding rear window and exterior LED lighting further contribute to excellent visibility around the entire working area. Fuel Tank Large 275-gallon (1,040 L) fuel tank capacity allows for longer run periods between refills. Excellent fuel economy reduces fuel costs and downtime for refueling. Transport Attachments fold completely under the processor boom, allowing easy transport on the road.
