Are known. However, these walk-behind mowers have an obstacle to the grass cutting in the front center part of the cutting blade housing in consideration of the mowing work efficiency, the left-right balance of the machine body, and the scraping property of the cutting grass into the cutting blade housing. In many cases, the grounding wheel is provided outside the right and left sides of the blade housing without widening the grounding wheel. These walk-type mowers equipped with wide contact wheels and running wheels are relatively small, but when performing mowing work on narrow ridges, the abdomen of the machine touches the ground and cannot be mowed. It was Therefore, an object of the present invention is to provide a walk-behind mower capable of performing wide-ranging mowing work on a flatbed and easily and efficiently performing mowing work such as ridges.

Since the grounding wheel attachment portion 7 is provided in the central portion on the upper front side of the cutting blade housing 3 and the grounding wheel 2a is configured to be attachable to and detachable from the grounding wheel attachment portion 7, it is possible to perform grass cutting work on a flat land or the like. In this case, the stability of the machine body 1 and the scraping property of the grass can be improved by expanding the width of the grounding wheels 2 and 2 at the left and right outer side positions of the cutting blade housing 3 and the left and right traveling wheels 5 and 5 by widening the gap W. When performing grass cutting work such as narrow ridges, the grounding wheel 2a is attached to the grounding wheel attachment portion 7 provided in the front upper center portion of the cutting blade housing 3, and the left and right running wheels 5, By narrowing the 5-interval W to a narrow width, it becomes possible to perform a mowing operation such as a ridge that is narrow enough to walk. Further, even if the grounding wheels 2 and 2 are adjusted to move up and down, the front ends of the grounding wheels 2 and 2 do not project from the front end F of the side plate 35. There is little grass involvement in 2.
