PROBLEM TO BE SOLVED: To perform pitching control of a vehicle body over a wide angle range while lack of mowing height adjustment is hardly generated at mowing work. SOLUTION: In the mowing harvester, an attitude change operation means 100 capable of changing a front/rear inclination angle of the vehicle body V relative to a ground-contact part of traveling devices 1L, 1R; and a control means 200 for executing pitching control for controlling operation of the attitude change operation means based on the detection information of a front/rear inclination angle detection means 24 for the front/rear inclination angle relative to a horizontal reference plane of the vehicle body are provided. The mowing harvester is provided with a pair of driving means C2-C5 capable of independently change/adjusting height relative to the ground-contact part of the traveling device at a front side in the vehicle body and height relative to the ground-contact part of the traveling device at a rear part in the vehicle body. The control means operates the pair of driving means C2-C5 for performing the pitching control and is constituted such that the driving means C3, C5 acting on the rear part of the vehicle body are not driven to a raising side of the vehicle body during retreating.
