PROBLEM TO BE SOLVED: To perform the control of overload of a motor part while keeping its working efficiency well.SOLUTION: The working vehicle equipped with a traveling part capable of self-traveling, a working part performing the work, and the motor part for driving these traveling part and working part, includes load-detecting means for detecting the load of the motor part and traveling speed-regulating means for automatically regulating the traveling speed of the traveling part based on the detected load information detected by the load-detecting means. In the case that the load-detecting means detecting the overload of the motor part, the traveling speed-regulating means forcibly decelerates the traveling speed of the traveling part to perform regulation for dissolving the overloaded state of the motor part. The working vehicle includes information-processing means for process-treating the detected load information detected by the load-detecting means and strength-adjusting means for strength-adjusting the degree of process-treatment of the detected load information process-treated by the information process-treating means.COPYRIGHT: (C)2011,JPO&INPIT【課題】作業能率を良好に確保したまま、原動機部の過負荷制御を行うこと。【解決手段】自走可能な走行部と作業を行う作業部とこれら走行部と作業部を駆動する原動機部とを備える作業車において、原動機部の負荷を検出する負荷検出手段と、負荷検出手段により検出される負荷検出情報に基づいて走行部の走行速度を自動的に制御する走行速度制御手段とを備えて、負荷検出手段が原動機部の過負荷を検出した場合には、走行速度制御手段が走行部の走行速度を強制的に減速して原動機部の過負荷状態を解消する制御を行う作業車であって、負荷検出手段によって検出される負荷検出情報を加工処理する情報加工処理手段と、情報加工処理手段が加工処理する負荷検出情報の加工処理度合いを強弱調節する強弱調節手段とを備えているを特徴とする。【選択図】図4
