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.

The "04" designation signifies its capability. This mechanical front-wheel drive, combined with its substantial weight (nearly 6 tons), provided the traction necessary to pull massive multi-furrow plows and wide cultivators that smaller machines simply couldn't handle.
