Barko B-Series harvesters and feller bunchers
May 6, 2016 — Featuring numerous enhancements from the original design, Barko’s B-Series harvesters and feller bunchers offer exceptional productivity and efficiency. Purpose-built from the ground up, the machines incorporate extensive input from leading engineers, end users, and other forestry professionals.
The 240B and 260B machines are each driven by a 225-horsepower Cummins QSB6.7 Tier 4 Final diesel engine with SCR aftertreatment. Offering a peak torque increase of 10 per cent from the previous models, the harvesters deliver superior productivity and fuel efficiency for reduced operating costs. The machines are also equipped with an extreme cooling engine package and a 36-inch-diameter Flexxaire auto-reversing fan that includes automatic temperature control.
The D5 undercarriage on the 240B offers ground clearance of 26.2 inches, compact track width of nine feet, four inches, and max travel speed of 2.47 mph. The 50,000-pound class unit delivers impressive maximum tractive effort of 65,833 foot-pounds, and drawbar pull of better than 1.3 to 1 ratio, to handle steep hills and rough terrain with ease.
The 260B features a wider D7A undercarriage with 8-inch chain pitch for added stability with larger attachments in the 60,000-pound class machine size. It maintains exceptional drawbar pull (1.13 to 1 ratio) and provides 65,481 foot-pounds of tractive effort. Ground clearance for the 260B is 29 inches. Options for both models include various track shoe sizes and five counterweights ranging from 1,000 to 5,500 pounds.
