PERFECCIONAMIENTOS EN EL CONTROL DE LA CARGA PARA EL MOTOR DE UN VEHICULO PARA LABORES AGRICOLAS.

摘要

Load control for engine of vehicle for agricultural work with rotary working implement, for avoiding too much deviation of the working depth while preventing the engine from stopping under heavy overloading. The rotary working implement is automatically raised and lowered in accordance with the results of sensing the engine rotation and of the actual working depth. For prevention of the engine failure, the rotary working implement is unconditionally raised whenever engine rotation below a predetermined value is sensed.
