In the world of agricultural machinery, the Ursus 1604 remains a respected workhorse—a testament to a time when tractors were built to be over-engineered, loud, and virtually unstoppable.
At its core, the 1604 is powered by a robust (the Martin Z8602.12), displacing roughly 6.8 liters. It produces approximately 150 to 155 horsepower , a formidable figure for its era. This power is managed through a manual transmission with 16 forward and 8 reverse gears, often featuring a hydraulic power torque amplifier that allowed operators to shift under load—a critical feature for maintaining momentum in heavy clay or uphill pulls.

Visually, the Ursus 1604 is defined by its "square" aesthetic—a brutalist, functional design typical of the Crystal series. The cabin was remarkably advanced for its time, featuring a safety-frame construction, basic soundproofing, and heating. While it lacks the digital refinement of modern tractors, its mechanical simplicity made it relatively easy to repair in the field with standard tools, contributing to its legendary longevity.
