CONTROLLER FOR ENGINE REVOLUTION OF MOBILE AGRICULTURAL MACHINE

摘要

PURPOSE:To maintain revolution of an engine within a proper region, by sensing the revolution of the engine and controlling the engine revolution and travel speed so as to maintain the engine revolution within the constant standard region. CONSTITUTION:Revolution of an engine 1 in a travel work is sensed with a revolution sensor 2. If the load is increased to lower the revolution of the engine 1 from the constant standard region, the revolution of the engine 1 is increased and controlled by throttle control so as to control the revolution within the standard region. If the load is decreased during travel work and the revolution of the engine 1 is increased over the constant standard region, automatic speed change control is carried out to accelerate and travel a steeples speed change device.
