STEYR M 975 POWER
ENGINES OVERVIEW
The Steyr M 975 tractor is powered by a choice of two diesel engine configurations: the MWM 3.1L 3-cylinder and the Sisu 3.3L 3-cylinder, providing a balance of power and fuel efficiency suitable for agricultural applications. Advantages include compact design and maneuverability, beneficial for small to medium-sized farms; however, challenges may arise in higher power-demand scenarios or heavier towing tasks due to the engine output limitations. It is essential to consider the engine's torque characteristics for optimal performance based on the specific towing or loading requirements in your operations.

ENGINE DETAIL 1
The Steyr M 975 tractor features a robust MWM 301.88 turbo diesel engine with a displacement of 3.1L, delivering 75hp at 2250 RPM and a substantial torque of 205 lb-ft at 1500 RPM, making it efficient for heavy-duty tasks. The 3-cylinder configuration offers a balance of power and fuel efficiency, suitable for moderate agricultural operations and utility work. Potential challenges include the engine's vibration at higher RPMs and maintenance complexity due to the turbocharged design, which could impact long-term reliability if not managed properly.

ENGINE DETAIL 2
The Steyr M 975 tractor is powered by a Sisu 320.81 turbocharged 3-cylinder engine, offering a balanced combination of power at 75hp and torque peak at 214 lb-ft at 1400 RPM, making it efficient for mid-range applications. Its 3.3L displacement and low RPM rating suggest optimum fuel efficiency, particularly suited for heavy-duty tasks such as plowing or transport under moderate loads. However, a potential challenge could be reduced power for high-draught implements, necessitating careful match-ups with required attachments.
