  • 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.
  • The upper frame uses specially designed mountings to support the heavy-duty cab, and the lower frame is reinforced to enhance component durability.
  • Work up to 3000 m (9,840 ft) above sea level without de-rating.
  • Don't let the temperature stop you from working. The MH3040 has a standard high-ambient temperature capability of 43°C (109°F) and cold start capability of -20°C (-4°F). Consult your Caterpillar dealer for additional information on special Configurations of your machine.
  • Auto warm-up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.


  • Use up to 25 percent less fuel than the M325D L MH in similar applications.
  • The C7.1 engine can run on biodiesel up to B20 and meets U.S. EPA Tier 4 Final and EU Stage V emission standards with an aftertreatment system that requires no maintenance or downtime.
  • The advanced 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.
  • Boost lifting capabilities and improve the controllability of heavy loads with heavy lift mode.
  • Match your machine to the job with selectable power modes. Let Smart mode automatically match engine and hydraulic power to working conditions. Power mode constantly provides maximum productivity.
  • Standard Product Link collects data automatically and accurately from your assets - any type and any brand. Information such as location, hours, fuel usage, productivity, idle time, maintenance alerts, diagnostic codes, and machine health can be viewed online through web and mobile applications.


  • Expect up to 20 percent lower maintenance costs than the M325D L MH.
  • Track your machine’s filter life and maintenance intervals via the in-cab monitor.
  • No required maintenance on the Cat Clean Emissions Module.
  • Change all fuel filters at a synchronized 1,000 hours.
  • Expect the new air intake filter with precleaner to last up to 1,000 hours.
  • 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.
  • High-efficiency, electrically driven cooling fans run only when needed; you can program intervals, so they automatically reverse to keep cores clean without interrupting your work.
  • Fine mesh protects the cooling hood from dust and debris.
  • S·O·SSM ports simplify maintenance and allow for quick, easy extraction of fluid samples for analysis.


  • The wide seat adjusts for operators of all sizes.
  • Get in and out of the cab easier using the tip-up left console.
  • Control the machine comfortably with easy-to-reach controls all located in front of you.
  • 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.


  • Equip your MH3040 with an optional 20kW generator for magnet operation.
  • Match your machine to the application. Multiple configurations allow you to customize your machine for millyard, scrap, and log loading applications.
  • Expand your work capabilities with attachments for a variety of applications.


  • Keep your machine secure with Operator ID. Use your PIN code on the monitor to enable the pushbutton starting feature.
  • Enjoy all-around great visibility with the help of smaller cab pillars, larger windows, and a flat engine hood design. Rearview and right-hand side-view cameras are standard.
  • Joystick steering eliminates the steering column, improving front visibility and increasing cab entrance width.
  • New 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.
  • Optional 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.
  • Boom and stick lowering check valves prevent reverse flow, keeping your front linkage securely in place should the hydraulic system unexpectedly lose power.


  • The Cat® C7.1 engine meets U.S. EPA Tier 4 Final and EU Stage V emission standards.
  • The MH3040 emits up to 34% less CO2 than the previous M325D L MH*.
  • Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels up to: 20% biodiesel FAME (fatty acid methyl ester) ** or 100% renewable diesel, HVO (hydrogenated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or "Caterpillar Machine Fluids Recommendations" (SEBU6250) for details.
  • Cat Scheduled Oil Sampling (S·O·S) Services helps reveal excessive wear, contaminated fluids or other "unseen" issues that can shorten component life. In many cases, you can extend oil and coolant change intervals by using fluid monitoring. Consult your Cat dealer or the machine's operation and maintenance manual for more information.
  • Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
  • VisionLink® displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
  • Remote Flash minimizes downtime and maintenance time while keeping your asset running with maximum efficiency. Alerts for machine updates are sent virtually from your Cat dealer and updates can be deployed without a dealer technician needing to be onsite.
  • Remote Troubleshoot decreases maintenance time and keeps your machine running with maximum efficiency by allowing your Cat dealer to virtually test the machine while working. Once a problem is identified, a technician can fix it the first time, saving time and money.

*All comparisons to M325D L MH. Productivity, fuel and CO2 emissions vary by application. CO2 emissions calculations based on a reference work cycle using 2.2 U.S. gallons per hour of #2 U.S. diesel fuel based. Applies IPCC2006 methodology using U.S. EPA Emissions Hub emission factors. Includes DEF (diesel exhaust fluid) related CO2. Fuel measurements are at 15°C. Estimated average fuel consumption improvements are based on tests or Product Link® data where available. Productivity improvements are based on test data.
**Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel.
