• Motor grader — A heavy self-propelled construction machine, equipped with a long adjustable blade mounted between the front and rear axles, used in road construction and earthworks for grading, leveling, smoothing soil or gravel, and for snow removal.
• Self-propelled plow — An agricultural machinery or integrated technical aggregate capable of performing plowing operations in a motorized and independent manner, without being towed by a secondary vehicle, or a device equipped with modern systems for structural self-regulation of depth and working angle during travel. In modern machinery engineering, the term can also describe a fully robotic plow, guided by GPS and proximity sensors, which traverses agricultural land without the direct intervention of a human operator.
• Self-propelled — Self-propelled, benefiting from an engine and an internal structural energy source; a machine, vehicle, projectile, or technical system capable of autonomous movement on roads, rails, or in space, without requiring towing, pushing, or a secondary towing vehicle. In industrial and military terminology, it describes a wide range of equipment (such as howitzers, combine harvesters, or cranes) mounted on its own self-propelled chassis.
