a machine frame;

a drive motor;

a ground milling device with a milling drum arranged inside a milling drum box and rotatable about a horizontal rotation axis extending transversely to a forward direction of the ground milling machine;

front and rear travel devices;

a right and a left lateral outer wall;

an operator platform;

a cover; and

wherein at least one of the right and the left lateral outer walls has, in the forward direction toward a front, a first sidewall region arranged in front of the operator platform in the forward direction toward the front, a second sidewall region positioned in front of the first sidewall region in the forward direction toward the front, and a third sidewall region positioned in front of the second sidewall region in the forward direction toward the front, wherein the second sidewall region protrudes sideways in a horizontal direction and perpendicular to the forward direction of the machine relative to the first and third sidewall regions and away from a longitudinal center of the machine extending in the forward direction,

wherein, in a vertical direction, a maximum lateral boundary of the machine is defined by at least one of the first, second and third sidewall regions, and/or the front travel device, and

wherein the second sidewall region is shorter in the forward direction than the first and/or third sidewall region,

wherein the cover provides a top side of the ground milling machine in a region in front of the operator platform in the forward direction, and comprises all cover parts visible in a top view from above the ground milling machine, and

any inclined surface(s) of the top side of the ground milling machine and of the cover is/are not of the first, second and third sidewall regions.
