Barko designed its new B-Series Industrial Wheeled Tractors, like the 937B above, to send extra power to attachments.Barko’s B-Series Industrial Wheel Tractors are designed to send more power to mulching heads and other attachments for land-clearing and various large municipal and commercial applications.
The company recently introduced two new models in the series, the 937B and 930B. The 937B has a 380-horsepower Cummins Tier 4 Final diesel engine with selective catalytic aftertreatment. The 930B runs on a 320-horsepower engine. Both models’ fuel tanks hold 127 gallons for longer operation. They also come with high-capacity anti-clog radiators with auto-reversing fan.
Their hydraulic systems automatically adjust attachment performance to the job, Barko says. The 937B can pump 113 gpm of hydraulic fluid at 5,500 psi, and the 930B pumps at 91 gpm and 5,000 psi. A high-capacity air cooler, along with variable-displacement piston pumps, cool the hydraulic fuel.
Along with mulching heads, the tractors can operate a variety of attachments, including rotary mowers, soil stabilizers, stump grinders, root rakes, rock crushers, loader buckets, snow plows and sweepers.
The Barko 930B Industrial Wheeled Tractor comes with a 320-horsepower diesel engine with top speed of 12 mph.For maneuverability, the tractors feature a 45-degree articulation joint to withstand stress. They have a turning radius of 15 feet, 9 inches. The 937B can travel up to 15 mph and the 930B up to 12 mph.
For maintenance, the tractors have one access point for greasing steering cylinders and axles. They have lockable and removable side panels and removable brake, engine and transmission covers. A variety of plates, guards and seals are designed to prevent debris from entering the machines. A 20-micron return filter also helps keep debris from damaging pumps and valves, Barko says.
The cabs are certified for roll-over and falling-object protection and are sound-insulated, climate-controlled and come with adjustable bucket seats.
Options for the tractors include a 30,000-pound hydraulic winch, a rearview camera with 7-inch LED color display, automatic fire-suppression system, hydraulics tank heater, engine block heater, joystick travel control, mulcher head terrain-float system and attachment tachometer.
