用トラクタのドラフト制御装置。 In an agricultural tractor equipped with a draft control mechanism that detects a draft force from the working part and controls the raising and lowering operation of a working part towed by a traveling machine so that the draft force reaches a preset value, the draft control mechanism includes: In addition to the normal speed mode in which the descending speed of the working part is set for normal work, a lowering speed mode means is set in which a mode higher than this mode is set, and the traveling aircraft changes to a posture that requires lowering of the working part. An agricultural tractor characterized by comprising: attitude change detection means for detecting the attitude change; and mode switching means for switching the descending speed mode means from the normal speed mode to the high speed mode based on the attitude change detection by the attitude change detection means. Draft control device.
