The diverse requirements pose complex demands on today's agricultural tractors. Effective work requires a modern diesel engine to have an efficient and versatile drivetrain, since the engine's performance must be transmitted to the ground and the wheel with minimal loss. At the same time, the activated gear ratio ensures optimum engine load in the otherwise wide range of speeds to reach low fuel consumption. For this reason, powershift transmissions are most often used under modern loads. The critical point of their operation is the gear shifting under load - the gear shifting process which is achieved by the controlled sliding of multidisc wet clutches. The research work focuses primarily on these clutches, starting from the electric signal controlling the shift, due to the displacement of the hydraulic actuation elements, taking into account the change in the drawbar force exerted.
