PROBLEM TO BE SOLVED: To provide a grass mower that is easy to set a mowing height and can stably travel for mowing. SOLUTION: By an up-and-down position adjustment for front wheels 1 provided to a traveling machine body 3 with respect to the traveling machine body 3, a road cutting device 4 is configured so that a mowing height thereof is adjustable. By an up-and-down swing of a slope cutting device 5 with respect to the road cutting device 4 about the axial center Q in the machine body transverse direction, the slope cutting device 5 is configured so that a mowing height thereof is adjustable because the slope cutting device is switched to an inclined posture in the front-and-rear direction of the machine body with respect to the road cutting device 4. The slope cutting device 5 is fitted with a ground contact body 51 in the lower end of a rotary drive shaft 33 on an up-and-down oriented posture for driving a slope cutting blade 49 of the slope cutting device 5. A ground contact surface of the ground contact body 51 is formed in a curved surface shape protruding downwardly in a bowl shape as it approaches the central part. COPYRIGHT: (C)2011,JPO&INPIT
