  • Engine
    The 937B is powered by a 380-HP Cummins QSL9 Tier 4 diesel engine with SCR aftertreatment. The unit includes a high-capacity anti-clog radiator with auto reversing fan.
  • Load Sensing Hydraulics
    Unlike open 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 efficiency.
  • Hydraulics / Attachment Drive
    With pressure ratings up to 5,500 psi, a high-flow hydraulic pump delivers far more horsepower to the attachment than competitive 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.
  • Travel System
    A hydrostatic transmission with two-speed transfer case allows for controlled operation speeds and travel speeds up to 15.8 mph (25.4 km/h).
  • High Strength Construction
    Weld blending and engineered sweeping curves provide added strength and increased fatigue resistance.
  • Bolt-On Cylinder Glands
    High-strength hydraulic cylinders with bolt-on glands combine maximum durability with easy serviceability on-site.
  • Cover Plates
    Cover plates, guards and seals help prevent debris from getting into the machine.
  • Centralized Lubrication
    Routine maintenance is simplified by a centralized lubrication station that provides one access point for greasing steering cylinders and axles.
  • Service Access
    Tractor includes lockable and removable side panels, as well as removable side, front and bottom brake, engine and transmission covers. An integrated toolbox keeps tools handy when needed.
  • Operator Cab
    ROPS and FOPS certified, the tightly sealed, vibration-isolated floating cab features sound insulation and an adjustable bucket seat with 4-point harness. Climate controlled with air conditioning and heating with defroster, the cab includes dual joystick controls, pilot operated foot travel and brake pedals, and various control buttons.
  • Visibility
    The 937B offers tinted Lexan glass on all windows. An air knife system keeps the front windshield clear of debris. A total of 9 mounted cab lights provide enhanced visibility around the machine.
  • Fuel Tank
    127-gallon (481 L) fuel tank capacity allows for longer operating intervals.
  • Articulation Joint
    A unique 45-degree articulation joint withstands extreme stress and tough terrain, while the machine’s overall maneuverable design allows for work in tight spaces.


  • Quick Attach
    Exclusive Quick Attach system allows for fast attachment changes and is compatible with common attachments including, but not limited to:
    Mulching Heads
    Rotary Mowers
    Soil Stabilizers
    Stump Grinders
    Root Rakes
    Rock Crushers
    Loader Buckets

  • Accessories
    Hydraulic tank heater
    Engine block heater
    Joystick travel control
    Mulcher head terrain float system
    Additional tire options

  • Hydraulic Winch
    In place of the toolbox, users can instead equip the tractor with a 30,000-pound capacity hydraulic winch.
  • Rear-View Camera
    Enhance visibility further with a rear-view camera with 7-inch LED color display.
  • Fire Suppression
    AFEX automatic fire suppression system available.
