The present utility model discloses a hybrid grass cutting apparatus, comprising a strimmer assembly, the strimmer assembly comprising a cutting head assembly located at an end remote from a handle and connected via a connecting rod, the cutting head assembly comprising a cutting tool and a guard located close to the cutting tool. The hybrid grass cutting apparatus further comprises a grass cutter frame, the grass cutter frame having an opening which accommodates the guard and through which the cutting tool can pass; and an engagement feature is provided between the grass cutter frame and the guard, enabling a user to engage the strimmer assembly with the grass cutter frame or remove the strimmer assembly from the grass cutter frame without any need to use an additional tool.

A hand-guided motorized working apparatus and an operating device for the apparatus are provided. The operating device has a handle shank configured to be hand-gripped, an operating element receiving region adjoining the handle shank, and an operating unit which acts on the apparatus operation and includes an operating element which is held movably on the operating element receiving region for actuation by a finger of a hand gripping the handle shank, and has a finger rest region extending along an outer side of the operating element receiving region. In the operating device, the operating element is a pivot operating lever which is held on the operating element receiving region so as to be pivotable about a pivot axis, wherein the pivot axis extends with a main direction component perpendicular to a shank longitudinal axis of the handle shank, and wherein the finger rest region, in a longitudinal extension along the outer side of the operating element receiving region, has a bent and/or angled course with a circumferential direction component and an axial direction component.

A system includes a garden implement handle device that is disposed on a garden care machine. The garden implement handle device has an operating unit. The operating unit has an operating element that is configured for actuation by an operator. The garden implement handle device has a further operating element that is configured for actuation by the operator. The system further includes an electronics unit configured to switch an energy supply of a drive unit based on the actuation of the operating element and an actuation of the further operating element. The operating element and/or the further operating element are a touch-sensitive electronic operating element.

Ergonomic gripping mechanisms of battery-operated electric cutting apparatus are provided. The electric cutting apparatus may include a cantilevered cutting head, an adjustable telescoping shaft, a rear grip portion, a pistol grip, and a forearm shaft. The adjustable telescoping shaft may be pivotally connected to the cantilevered cutting head. The rear grip portion may have a first end connected to the adjustable telescoping shaft. The pistol grip may have a first end extending at a first angle from the second end of the rear grip portion. The forearm shaft may extend from the second end of the pistol grip at a second angle. The forearm shaft may have a top side comprising a forearm pad having an exterior surface configured to receive a forearm of a user. The exterior surface of the forearm pad may be parallel to an axis defined by a longitudinal extension of the adjustable telescoping shaft.

A string trimmer support attachment. The device includes a base on which the shaft of a string trimmer can be secured. The present invention further includes a pair of legs that are pivotally attached to the base. The legs can be folded so as to be aligned against the string trimmer shaft when not in use. Alternatively, the legs can be folded outward so that the legs are roughly perpendicular to the string trimmer shaft in order to support the head of a string trimmer in an upright and angled orientation that is convenient for changing the trimmer line. Further, in the unfolded configuration the legs are disposed at an angle relative to one another to provide a stable support for the string trimmer, wherein the string trimmer proximal end acts as a third portion of a tripod when the legs are deployed.
