Abstract
A tractor is provided for suppressing pitching in which a front part of a traveling vehicle body is lifted upward, while a suspension mechanism functions when work is carried out with a ground implement. When a raise control signal for raising the plow is detected in draft control for elevating/lowering the plow based on a draw load value detected by a draw load sensor, mode switching means suppresses or limits the suspension function, via control of the suspension control means to suppress an event in which the front part of the traveling vehicle body is lifted upward. When the raise control signal is not detected, the mode switching means causes the suspension mechanism to function via control of the suspension control means.
