PRODUCT Detail
As sure as a rooster crows, you can expect a QSM-powered tractor to perform. Every morning. Whether you’re pulling a chisel plow, cultivating a row crop or hauling in a wagonload of hay, the QSM gets it done. With superior performance that’s the result of advanced combustion technology and our responsive wastegated turbo. Electronically controlled unit injectors with cam-driven rate shaping optimize both emissions and efficiency.
Maintenance is kept to an absolute minimum, with oil change intervals that are double the previous standards in some applications, sealed sensors and an auto-tensioning belt drive.
Available in a range of ratings from 250-400 hp (186-298 kW), every QSM is perfectly matched to every piece of equipment. The QSM not only meets Tier 2 and Euro Stage II emissions standards, its advanced design can reach Tier 3 and Stage IIIA requirements as well, with minimal changes. Cummins engineers work with the original equipment manufacturers, shaping power curves and ratings to align with work environment, load factors and operating modes. Then, we optimize the engine’s performance with other vehicle components and subsystems, using Cummins Advisor.
The QSM comes with virtually every feature standard. QSM options include REPTO (Rear Engine Power Take-Off).
Every QSM engine is covered by Cummins three-step warranty, one of the most comprehensive and simplest in the industry.
The QSM high-pressure injection system and electronic controls ensure clean, powerful and efficient operation every time. The ECM continuously monitors data from strategically placed sensors within the engine, optimizing the fuel-to-air mixture for maximum combustion. This increases engine responsiveness, improves fuel efficiency and significantly reduces noise levels.
The Holset wastegated turbos provide high efficiency and responsive torque every time for everyday dependability.

Every Cummins QSM engine is designed to go the distance, with heavy-duty components that have been proven in hundreds of applications, around the world.
- Advanced Combustion Technology – Optimized injector tips and a reshaped steel piston bowl improve fuel economy and emissions control, resulting in longer change intervals.
- Articulated Pistons – Steel-topped articulated pistons handle higher cylinder temperatures for improved fuel economy and emissions control.
- Patented Mid-Stop Cylinder Liners – Resist cavitation, extend life-to-overhaul.
- Improved Camshaft Design – Exhaust valve lobes are designed to improve wear tolerance, and the injector lobe profile has been revised to optimize injection.
- Sealed Sensors – Fully sealed to resist water intrusion and enhance reliability. Combined temperature and pressure sensors reduce inventory and simplify maintenance.
- CELECT™ Electronic Engine Management – Provides superior performance, fuel efficiency, diagnostics and prognostics using full-authority electronics. Its programmable features let you customize engine performance to equipment use.
