摘要： A traveling vehicle includes a controller to control a posture of a work machine via a connector. The controller observes whether a farm field surface on which the traveling vehicle travels and the work machine maintain a predetermined positional relationship therebetween, and controls the posture of the work machine when a positional relationship between the farm field surface and the work machine changes from the predetermined positional relationship, so that the positional relationship thus changed is reset to the predetermined positional relationship.

摘要： Provided is a tractor which allows continuation of a plowing work by appropriately elevating a plow when slip occurs in wheels. The tractor includes draft controlling means (34) for elevating the plow to a target machine body level value obtained by making reference to control information with a draft load value detected by a draft load sensor (S). The control information is set based on a target plowing depth set when the plow was set to a target plowing depth and a draft load value. When a slip ratio detected by a slip ratio acquiring means (37) exceeds a threshold value, in place of previously set control information, there is newly set control information which renders higher the target machine body level relative to a same draft load value, thereby to elevate the plow.
摘要翻译：提供一种拖拉机，其能够通过在车轮中发生滑移时适当地升高犁来延续犁耕作业。拖拉机包括用于将犁升至通过参考由牵引载荷传感器（S）检测到的牵引载荷值的控制信息而获得的目标机体水平值的牵引控制装置（34）。基于当犁设定为目标耕作深度和吃水载荷值时设定的目标耕作深度来设定控制信息。当由滑移率获取装置（37）检测到的滑移率超过阈值时，代替预先设定的控制信息，存在新设定的控制信息，使得相对于相同的牵伸载荷值使目标机体水平更高，由此提高犁。
