摘要：
A handheld edger includes an electric powerhead coupled to a mounting location, a member, and a cutting assembly. The electric powerhead includes a motor having an output shaft rotating at a first speed about an output shaft axis and a battery configured to power the motor. The member extends from the mounting location and includes an upper portion and a lower portion, the lower portion configured to be removable and replaceable to exchange one or more attachments. The cutting assembly coupled to the member includes a drive shaft, a blade coupled to and driven by the drive shaft, and a worm drive coupled to the output shaft of the motor and the drive shaft, the worm drive configured to cause the drive shaft to rotate the blade at a second speed. A gear ratio of the worm drive is larger than 40:1.
