Abstract
To discharge an object to be cut such as grass or lawn which has intruded between a first blade and a second blade while preventing the object to be cut from intruding between the first blade and the second blade.SOLUTION: A work machine includes: a first blade; a second blade overlapping on the first blade in a vertical direction; a first guide member overlapping on the first blade on an opposite side to the second blade relative to the first blade in the vertical direction; and a second guide member overlapping on the second blade on an opposite side to the first blade relative to the second blade in the vertical direction. The first blade includes a first long hole. The second blade includes a notch extending toward a first side face of the second blade from a second side face which is located on an opposite side to the first side face of the second blade. When the first blade reciprocates relative to the second blade, at least a part of the first long hole of the first blade overlaps on the notch of the second blade in the vertical direction.SELECTED DRAWING: Figure 8
