Definitions:

RPM

Stands for Revolutions Per Minute, a measurement of the speed of rotation of a mechanical component.

Deep-Reduction Transmission

A transmission designed to significantly decrease the gear ratio, providing a higher torque at low speed, often used in heavy-duty vehicles.

Low-Low Ratio

A very low gear ratio in a vehicle's transmission, providing maximum torque output for situations requiring increased power at low speeds, such as off-road.

Teeth Drives

Mechanisms that use gear teeth to transmit power and motion between shafts in machinery.
