摘要： An engine speed control system for a work vehicle comprises a pedal sensor (32) for detecting an operative position of an accelerator pedal (31); a foot accelerator controller for carrying out foot accelerator control in which the engine speed that corresponds to an output of the pedal sensor (32) is used as a target rotational speed; and upper limit setting device (35) for setting the upper limit of the engine speed. The upper limit rotation control in which the upper limit rotational speed is used as the target rotational speed is carried out when the target engine speed is greater than the upper limit rotational speed set by the upper limit setting device (35).

摘要： The engine speed control system for a work vehicle has a foot accelerator controller for carrying out foot accelerator control based on a pedal sensor, a hand accelerator controller for carrying out hand accelerator control based on a lever sensor, a manually operated input device, storage means for storing a predetermined engine speed, and a constant rotation controller for carrying out constant rotation control in which the engine speed stored in the storage means is used as the target rotational speed on the basis of an input to the input device. The constant rotation control is carried out when the input device has been operated in the case that the engine speed that corresponds to the output of the lever sensor is greater than an idling speed, and the constant rotation control is terminated when the input device is operated in the case that the engine speed that corresponds to the output of the lever sensor is equal to or less than the idling speed.

摘要： A work vehicle with a speed change device, comprises, a plurality of wheels including at least one driven wheel; an engine for driving the driven wheel; a speed change device provided between the driven wheel and the engine; and automatic shifting mechanism. The automatic shifting mechanism is capable of operating the speed change device to a lower speed position within an automatic shifting range having a predetermined range and is capable of operating the speed change device up to a speed position which the speed change device was in before an operation to the lower speed position was effected, in response to load on the engine. The entirety of the automatic shifting range is changeable to a low speed side and to a high speed side or the automatic shifting range can be widened to include more speed positions and narrowed to include less speed positions.
