A hedge trimmer includes a blade assembly having a first blade and a second blade, a housing, a prime mover, and a transmission device. The first blade includes a first body portion and a plurality of first tooth portions, and the second blade includes a second body portion and a plurality of second tooth portions. The first blade includes a first connection assembly including a first driving portion and a first connecting portion, and the second blade includes a second connection assembly including a second driving portion and a second connecting portion. The first connecting portion and the first body portion form a detachable connection, the second connecting portion and the second body portion form a detachable connection, and the first connecting portion is at least partially located outside the housing.

A gardening trimmer may include: a first blade connected to a first cam member and configured to reciprocate in response to rotation of the first cam member; and a second com connected to a second cam member and configured to reciprocate in opposite phase to the first blade in response to rotation of the second cam member. The first cam member includes a first eccentric cam configured to revolve around a first rotation axis and is connected to the first blade at the first eccentric cam. The second cam member includes a second eccentric cam configured to revolve around a second rotation axis and is connected to the second blade at the second eccentric cam. Each of the first and second blades is configured to reciprocate along a plane including the first and second rotation axis.

An electric handheld working machine includes: a housing including: a motor as a drive source of a working unit; an operating handle; and attaching members provided on an outer surface of the housing and configured to attach a battery to supply electric power to the motor. The attaching members includes: a connecting terminal connected to the battery; a step provided above the connecting terminal and configured to function as a drainage path to drain drops of water to sides; and openings formed in the sides of the attaching members to communicate with the drainage path. The openings communicate with a cooling air flow path configured to allow cooing air to flow through a gap between a back surface of the battery attached to the attaching members and the outer surface between the attaching member.

A tree saw attachment for a modular landscape trimmer is disclosed. In one embodiment, the tree saw attachment is provided with a drive unit having a drive shaft operably connectable to a motive source and a transmission operably connected to the drive shaft. An anvil is connected to and extending from an output side of the transmission of the drive unit, and a blade is connected to the output shaft of the transmission. The blade has an arcuate outer peripheral edge with teeth formed along a portion thereof forming a cutting edge so as the output shaft is rotated, the distance between the cutting edge and a central axis of the output shaft increases until the blade has substantially completed one rotation. Rotation of the blade causes the blade to move transversely with respect to the anvil to engage and cut material positioned between the blade and the anvil.

A hedgetrimmer having a blade assembly that includes a sawblade for cutting through larger branches and other vegetative foliage. The blade assembly includes a reciprocating blade having an integrally formed sawblade portion that moves back and forth cutting motion. The other blade is fixed and includes a bevelled interior edge that helps debris being cut to pass over the blade and prevent getting stuck.

A method for attaching a removable saw blade to a reciprocating type hedge trimmer to extend the utility for cutting larger diameter stalks without requiring a second appliance. The removable nature of the blade allows replacement should the blade become dull or damaged, and also allows use of the trimmer without the blade installed with minimal impact to the base functionality of the trimmer. Such trimmer can be hand held or machine mounted and powered by a variety of power sources.
