    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.

    摘要： A small riding lawn mower having a grass cutting unit suspended from a body frame between a front axle and a rear axle, an engine supported by a body frame in a position forwardly of the rear axle with respect to a longitudinal direction of the body frame, a hydrostatic transmission disposed rearwardly of the rear axle, and a driver's seat disposed forwardly of the engine. The body frame includes profile members disposed at opposite sides and extending longitudinally of the mower, and a cross plate interconnecting the profile members. A belt transmission mechanism connecting the hydrostatic transmission to an engine output shaft is surrounded by a plate frame structure formed below the body frame. The plate frame structure defines a further independent chamber for accommodating a muffler of the engine. This chamber has peripheral walls shaped to guide cooling air from the engine to the muffler and laterally outwardly of the mower.

    摘要： A rotating rate control apparatus for adjusting rotation of an engine of a working vehicle between a minimum rate and a maximum rate. The control apparatus has a first, a second and a third rotating rate adjusting devices. The first rotating rate adjusting device adjusts a basic rotating rate of the engine between the minimum rate and maximum rate. The second rotating rate adjusting device is shiftable between an ON position and an OFF position. The second rotating rate adjusting device is operable, when in the ON position, to set the engine to a predetermined rotating rate between the minimum rate and the maximum rate inclusive. The third rotating rate adjusting device is operable, when the second rotating rate adjusting device is in the OFF position, to adjust the rotating rate of the engine between the basic rotating rate adjusted by the first rotating rate adjusting device and the maximum rate.
