Offering a heavy-duty design for maneuvering across rough terrain, Barko's B-Series Industrial Wheeled Tractors provide excellent fuel efficiency while increasing productivity. The machines deliver consistent performance for land clearing, right-of-way maintenance, site prep, and other large commercial and municipal applications.

The 937B model is powered by a 380-hp Cummins QSL9 Tier IV Final diesel engine with SCR aftertreatment, while the 930B features a 320-hp engine. Both include a high-capacity anti-clog radiator with auto reversing fan, along with a 127-gallon fuel tank that allows for longer operating intervals. Unlike loop systems that waste fuel, Barko's load sensing hydraulic system automatically adjusts attachment performance according to the load, resulting in greater productivity and higher fuel efficiency.

A high-flow hydraulic pump produces 113 gallons per minute (GPM) at 5,500 PSI for the 937B – 91 GPM at 5,000 PSI for the 930B – to deliver far more horsepower to the attachment than most comparable machines. High-capacity oil cooler and variable displacement piston pumps keep hydraulic oil cool to maximize service life. A high-pressure 20-micron return filter helps prevent debris from damaging pumps and valves.

The tractors' unique 45-degree articulation joint withstands extreme stress and tough terrain, while each machine's maneuverable design provides a turning radius of 15 feet, 9 inches to allow work in tight spaces. A hydrostatic transmission with two-speed transfer case allows for controlled operation speeds and travel speeds up to 15.8 mph for the 937B and 12.2 mph for the 930B.

Durably constructed, the tractors feature weld blending and engineered sweeping curves to provide added strength and increased fatigue resistance. High-strength hydraulic cylinders with bolt-on glands are durable and easily serviceable. A variety of cover plates, guards and seals help prevent debris from getting into the machine.

Routine maintenance is simplified by a centralized lubrication station that provides one access point for greasing steering cylinders and axles. The tractors include lockable and removable side panels, as well as removable brake, engine and transmission covers.

ROPS and FOPS certified, the tightly sealed, vibration-isolated floating cab features sound insulation and an adjustable bucket seat with four-point harness. The climate-controlled cab includes dual joystick controls, and pilot operated foot travel and brake pedals. Polycarbonate windows provide added safety, with an air knife system keep the front windshield clear of debris.

In place of a standard integrated toolbox, users can instead equip the tractor with an optional 30,000-pound capacity hydraulic winch. Other optional equipment includes a rear-view camera with 7-inch LED color display, automatic fire suppression system, hydraulic tank heater, engine block heater, joystick travel control, mulcher head terrain float system, and attachment tachometer.

Barko's exclusive Quick Attach system allows for fast attachment changes. While often used with mulching heads, the tractors can also be fitted with many other common attachments, such as rotary mowers, soil stabilizers, stump grinders, root rakes, rock crushers, loader buckets, snow plows, sweepers, and more.
