Abstract

PURPOSE: To improve the maneuverability and safety of an agricultural machine, by making a gear-shifting command from a switching control carried out in steps from the current state of transmission.
CONSTITUTION: A press on a switch F1 turns on a switching circuit SWF1 with a slight delay due to a preventive system of quick starting, which activates a solenoid S1. In the same manner, switches F2, F3, R activate solenoids S2, S3, SR respectively with a slight delay after pressing. The activation of solenoids S1, S2, S3 or SR makes a multiple-disc clutch fed with pressure oil and the machine travels its gears being shifted to the first, second, third or rear potion step by step. Even if the gear-shifting is not selected in the right order, the actual transmission is carried out step by step.
