According to examples, a machine may include a base housing and a handle assembly mounted to the base housing and extending at an angle from the base housing along a handle plane. The handle assembly may include a mating component having a plurality of slots arranged at multiple angular positions along a slot plane, the slot plane being parallel to the handle plane. The mating assembly may also include a handle segment rotatably mounted to the mating component, the handle segment housing a locking member, in which the handle segment is rotatable along the slot plane relative to the base housing and the locking member is removably insertable into a first slot of the plurality of slots when the handle segment is in a first angular position and is removably inserted into a second slot of the plurality of slots when the handle segment is in a second angular position.

A smart mower includes a housing with an inner housing located at a lower portion and an outer housing connected with the inner housing and located at an upper portion; a cutting mechanism; and a walking mechanism. The cutting mechanism and the walking mechanism are mounted in the inner housing. A handle is disposed on the inner housing adjacent the outer housing for conveying the smart mower. Projection of the handle on a horizontal plane is within a range of projection of the outer housing on the horizontal plane.

A device for extracting auxiliary power from a power source installed on or associated with an implement, and supplying the auxiliary power to an auxiliary tool associated with the implement. The invention is preferably employed in the context of an auxiliary tool, e.g., in the form of a rotary trimmer, edger or the like, associated with another power implement, such as a lawnmower, wherein the power is preferably extracted from a driven member of the implement. Advantageously, the device is easy to attach/detach, is universally locatable and/or orientable on the implement, and is easily retrofittable to practically any existing implement, such as a lawnmower deck.

A string trimmer attachment assembly for edging a lawn includes a weed trimmer that has a pole, a gear head that is coupled to the pole and a trimming head that is rotatably coupled to the gear head. The gear head is angled between the pole and the trimming head. A rolling unit is removably coupled to the pole of the weed trimmer. The rolling unit is oriented to extend along a perpendicular axis with respect to a rotational axis of the trimming head. Additionally, the rolling unit horizontally orients the rotational axis of the trimming head when the rolling unit is positioned to roll along a support surface. In this way the trimming head is positioned to perform edging along a vertical edge.
