A working machine may include: a prime mover; an output shaft configured to move by movement of the prime mover; a first adjusting member detachably attached to the output shaft; and a working member detachably attached to the first adjusting member. The first adjusting member may include: an attaching part attached to the output shaft; and an adjusting part attached to the working member and configured to adjust an attaching posture of the working member relative to the first adjusting member.

A working machine disclosed herein may include: a housing; a working member swingably supported by the housing and at least partially disposed outside the housing; and a counterweight disposed inside the housing and configured to swing as the working member swings. The working member and the counterweight may be configured to swing toward each other and swing away from each other.

Outdoor gardening tools are provided. An outdoor tool includes a powerhead unit and a tool unit powered by the powerhead unit. The tool further includes a user control member, and a grip member. The tool unit includes an elongated body having a shaft and a cutting element extending radially from the shaft, and a connector. The connector is configured to couple with a complementary connector of the powerhead. The tool unit is configured to be rotatably driven by the powerhead. The tool is configured to enable a user to dig a hole in a ground surface while maintaining a standing position.

Improved cooling systems for handheld devices are disclosed. In some aspects, the cooling system may utilize air inlets disposed behind a guard to prevent debris or liquids from entering the handheld device and potentially causing damage to internal components of the handheld device. In aspects, a vents may be disposed on the guard to divert cooling air into a housing of the handheld device to cool internal components, such as the motor or a printed circuit board (PCB). In additional or alternative aspects, a motor mount may be provided that includes ribs defining air channels to divert or direct cooling air to components to be cooled. The air channels provided by the motor mount may enable the cooling air to reach portions of the internal components that may be distant from the air inlets of the housing.

A ground treatment device including a housing fabricated from at least one injection molded part. An axle with a ground treatment attachment mounted thereto can be rotatably secured to opposing sides of the housing. The housing can include a gear housing structure which is configured to house gears for enabling operation of the ground treatment attachment using a power tool. An upper frame can be secured to opposing sides of the housing. The ground treatment attachment can be configured to cultivate the ground.

A weeding device provides a solution to the problem of removing dandelions and other weeds from a lawn or other area. The core components of the invention are a shaft and handle arranged so that a user can remove weeds while standing, a cutting head and motor configured to cut weeds, and an herbicide injector configured to inject an herbicide into the weed. Generally speaking, the components are configured as follows: the handle is at one end of the shaft and the motor, cutting head, and herbicide injector are at a second end of the shaft. The cutting head is configured to rotate around the herbicide injector to cut portions of the weed while herbicide is injected into the weed by the herbicide injector.
