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.

Abstract: A working vehicle includes a joy-stick lever which operates a front loader, and a main change lever etc., wherein a right side dashboard is located in the right side of the driver's seat, the forward end step part is located beside the steering wheel, and is provided with the joy-stick lever, a grip part of the main change lever is disposed at a lower position than the steering wheel, a grip part of the position lever is disposed at an outside position of the grip part of the main change lever on a plan view, and a grip part of the joy-stick lever is disposed at a front side position of the grip part of the main change lever on a plan view, and is disposed in a range of a height of the steering wheel on a side view.
