High Performance with Lower Fuel Consumption

  • Use less fuel versus the 330D MH with no impact on your productivity.
  • The C9.3B engine can run on biodiesel up to B20 and meets U.S. EPA Tier 4 Final emission standards.
  • Match the machine to the job with three power modes - Power, Smart, and Eco. Smart mode automatically matches engine and hydraulic power to working conditions, providing max power when needed and reducing power when it isn't to save fuel.
  • The advanced electro-hydraulic system provides the optimum balance of power and efficiency while giving you the control you need.
  • Valve priority puts hydraulic pressure and flow where you need it.
  • The variable gauge undercarriage retracts for easy transportation and expands for increased stability and lifting capacity.
  • Program and store your preferred power mode and joystick settings using your Operator ID. The machine will automatically remember your selections.
  • The Cat App helps you manage fleet location, hours, and maintenance schedules; it also alerts you for required maintenance and even allows you to request service from your local Cat dealer. Product Link comes standard so you can remotely monitor machine health, location, hours, and fuel consumption on demand.

Work in Comfort in the All-New Cab

  • The cab, with hydraulic cab riser, has a wide seat that adjusts for operators of all sizes and is heated and ventilated for optimum comfort.
  • Control the machine comfortably with easy-to-reach controls.
  • Standard automatic climate control keeps you at the right temperature all shift long.
  • Stow your gear with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles. A cup holder, document holder, bottle holder, and coat hook are also provided.
  • Use the standard radio's USB ports and Bluetooth® technology to connect to personal devices.
  • Machine settings can be controlled through the high-resolution, 10 inch, touchscreen monitor. It offers 42 languages and is easy to reach from the seat.

Superior Serviceability

  • Track your machine's filter life and maintenance intervals via the in-cab monitor.
  • Change all fuel filters at a synchronized 1,000 hours.
  • Expect the air intake filter with integrated pre-cleaner air filter to last up to 1,000 hours in most applications.
  • The new hydraulic oil filter provides improved filtration performance, anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3,000-hour replacement interval - 50 percent longer than previous filter designs.
  • The high-efficiency hydraulic fan has an optional automatic reverse function to keep ores free from debris, eliminating the need for any operator interaction.
  • S·O·SSM ports simplify maintenance and allowing for quick, easy extraction of fluid samples for analysis.


  • Keep your machine secure with Operator ID. Use your PIN code on the monitor to enable the push-button starting feature.
  • Enjoy great all-around visibility with the help of smaller cab pillars, larger windows, and a flat engine hood design. Rearview and side-view cameras are standard.
  • Standard 1800-lumen LED exterior lights illuminate your surroundings for a safer work environment.
  • Thick impact-resistant windshields fulfill P5A standards.
  • Service platform design provides easy, safe, and quick access to the upper service platform. The service platform steps use anti-skid punch plate to prevent slipping.
  • The standard hydraulic lockout lever isolates all hydraulic and travel functions in the lowered position.
  • Standard Falling Object Guard System (FOGS) provides protection from falling and flying debris.
  • Ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
  • In case of an emergency, lower the cab safely with the emergency cab lowering valve located behind the cab riser or to the right of the seat. The valve located behind the cab riser is easily accessible.
  • Boom and stick lowering check valves prevent reverse flow, keeping your front linkage securely in place should the hydraulic system unexpectedly lose pressure.
  • Make moving the excavator much easier with Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers or pedals.

Reliability and Durability You Can Count On

  • Count on your machine to withstand wear throughout the years. Boom, sticks, and other high-stress areas are reinforced with thick multi-plate fabrications, castings, and forgings to ensure quality and reliability.
  • Work up to 2600 m (8,530 ft) above sea level without derating.
  • Don't let the temperature stop you from working. The material handler has a standard high-ambient temperature capability of 52°C (125°F) and cold-start capability of -32°C (-25°F).
  • Auto warm-up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.

Versatility Keeps You Productive and Profitable

  • Equip your MH3250 with an optional 25 kW generator for magnet operation.
  • Expand your work capabilities with attachments for a variety of applications.
