Abstract
In structure of an engine control device for a tractor, when a standard engine performance curve is selected by a mode selection device, and a PTO drive device, which drives an implement attached to a tractor, is turned on, switching to the engine speed maintenance control mode is performed. Further, when a fuel efficient engine performance curve is selected by the mode selection device, and the PTO drive device, which drives the implement, is turned on, switching to the engine speed change control mode is performed. The problem that an engine stall tends to occur when control for maintaining the engine speed is performed while the fuel efficient engine performance curve with lower consumption rate than normal consumption rate is selected can be solved.
