A mower unit comprising:
- a blade rotatably driven about a rotational axis to be able to cut grass on the ground surface;
- a housing covering the blade and having an open lower face;
- a water feeding section provided outside the housing;
- a water discharging section provided inside the housing for discharging cleaning water fed to the water feeding section;
- and
- a water feeding pipe connected between the water feeding section and the water discharging section,
- wherein the water discharging section discharges water toward an inner wall face of the housing,
- wherein, inside the housing, there is provided a vertical wall portion having an arcuate shape along an outer shape of a rotational trajectory of the blade,
- wherein the water discharging section is provided at a portion located in a space formed between the vertical wall portion and a lateral wall of the housing located on the side opposite the side where the blade is located,
- wherein the water feeding pipe includes a main water feeding pipe connected to the water feeding section and a branch water feeding pipe branching from the main water feeding pipe and connected to the water discharging section,
- wherein the branch water feeding pipe is disposed in the space,
