Abstract: An angle impact tool includes: a brushless motor having a stator and a rotor, which rotates around a first rotational axis relative to the stator; an impact mechanism, which is rotated by the rotor; an output shaft, which is impacted by the impact mechanism and rotates around a second rotational axis; a motor housing, which houses the brushless motor; and one or more battery-mounting parts, on which one or more battery packs is (are respectively) mounted. In a front-rear direction, which is orthogonal to the second rotational axis, the impact mechanism and the output shaft are disposed more forward than the brushless motor. The front-rear direction and the output shaft are orthogonal to each other. The maximum fastening torque of the output shaft is 500 N·m or more and less than 1,000 N·m.

Abstract: A dust collection container includes a hollow member having a storage space, a tubular member fixed to the hollow member and defining a passage communicating with the storage space of the hollow member, and a biasing member. The tubular member includes at least one tubular wall, a protrusion, and a wall part. The at least one tubular wall extends along a first axis extending in a first direction. The protrusion protrudes from a first one of an inner peripheral surface and an outer peripheral surface of the at least one tubular wall in a direction orthogonal to the first axis. The wall part protrudes from the first one of the inner peripheral surface and the outer peripheral surface on which the protrusion is disposed. The biasing member is adjacent to the wall part of the tubular member, and between the protrusion and the wall part in the first direction.

Abstract: The cutter unit of a lawn maintenance machine may include: a shaft; and an even number of cutter blades aligned in a left-right direction extending from the first portion away from a rotation axis. Each of the even number of cutter blades may be attached to the shaft in one of the at least three postures. A number of the cutter blades disposed to a right of a center position may be same as a number of the cutter blades disposed to a left of the center position. A disposition of the cutter blades in the right-left direction as viewed from the center position toward the right may be same as a disposition of the cutter blades in the right-left direction as viewed from the center position toward the left. The postures of two cutter blades being at a same distance from the center position may be same.
