摘要： An engine hood construction for a work vehicle is disclosed. The engine hood is vertically separatable into a lower hood section and an upper hood section. The lower hood section is fixedly attachable to and detachable from a vehicle frame, and the upper hood section is attached to the vehicle frame to be pivotably and vertically opened and closed relative to the frame. A control panel is provided at a rear portion of the engine hood and forming a rear wall of an engine room. The control panel has a forwardly opened hook shape in a plan view. The construction further includes a connecting arrangement for fixedly connecting the lower hood section to the vehicle frame and engaging members for enabling the lower hood section to be engaged with the control panel along a fore-and-aft direction of the vehicle when the connecting arrangement is not connected.

摘要： An engine speed control system for a working vehicle having an engine, and a propelling transmission and a power takeoff device driven by the engine. Engine speed is adjustable by an accelerator controlled by control signals outputted from a control unit. The control unit is connected to a clutch operation detecting switch for detecting an operative state of a power takeoff clutch for operating a power takeoff device and to a shift condition detecting switch for detecting a shift of the propelling transmission. The control unit outputs a control signal for rotating the engine at an idling speed when the propelling transmission is in neutral and the power takeoff clutch is disengaged, and a control signal for rotating the engine at a high rotating rate when the propelling transmission is in a drive transmitting position or the power takeoff clutch is engaged.
