Abstract
A working machine may include: a conversion mechanism configured to convert motion of a prime mover; a first blade connected to the conversion mechanism; a second blade overlapping with the first blade in an up-down direction and facing a first facing surface of the first blade; a sealing member engaged with a first non-facing surface of the first blade that is opposite to the first facing surface, wherein the sealing member includes a first sealing surface facing the first non-facing surface in the up-down direction; and a cover member facing a second sealing surface of the sealing member that is opposite to the first sealing surface of the sealing member. The sealing member may be disposed forward of the conversion mechanism and configured to suppress the object cut with the first blade and the second blade from moving toward the conversion mechanism between the first blade and the cover member.
