A gardening tool adapted to being attached to a rake, the rake having an elongated handle and teeth. The gardening tool comprises a blade, an attachment system, a prong attachment and a prong. The blade has a perimeter defined by a first and a second lateral edges as well as a first and a second transversal edges. The attachment system, which attaches the blade to the rake, is operative to secure the blade against the teeth of the rake. The prong attachment is located on the blade proximate to the first lateral edge. The prong, being pivotally attached to the blade through the prong attachment, may selectively adopt one of the following positions: a) extending primarily beyond the first transversal edge; b) extending primarily beyond the first lateral side; and c) being stored primarily within the perimeter.

A tool comprises a blade operatively connected to a shaft and also comprises a foot plate operatively connected to the blade or the shaft. The tool is adapted for applications including, but not limited to, trenching and edging. In particular, the tool is adapted so the blade can travel forward in an arc without coming completely out of the soil. The blade can be designed to cut through roots up to a limited size.

The present invention relates to an angle adjustable connecting part for farm equipment and hand tools, which can easily detach a working part of farm equipment and a hand tool from a sack, and can be adjusted at various angles to allow many types of farm equipment to be interchangeably used. The present invention is configured such that: a connecting part is formed on the front end of a working part of farm equipment or a hand tool, a connecting part is also formed on the front end of a sack, and the working part and the sack can be coupled through the connecting parts; the connecting part has a fixing hole formed in the center thereof, and multiple angle adjusting holes are formed concentrically outward from the fixing hole; a fixing hole is formed at the center outward from the connecting part, and a fixing plate is provided having a fixing protrusion that is inserted into the angle adjusting hole formed outward thereon. When a fixing screw is inserted in and fixed to the fixing plate and the fixing hole of the connecting part, the fixing protrusion of the fixing plate is inserted in and fixed to an angle adjusting hole of the connecting part, and after the fixing screw is unscrewed, the connecting part can be turned to fix the working part and the sack at a desired angle.

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.

Aspects of the disclosure relate to a garden implement that includes a handle, at least one tool member having a pair of flanges extending therefrom, each flange includes a flange bore and a pinion segment that share a common center, the pair of flanges have opposing parallel surfaces that each include the pinion segment, the opposing parallel flange surfaces are spaced apart by a first distance. Also included is at least a first fixing member coupled between the pair of flanges and the handle. The first fixing member includes a boss projecting along a longitudinal axis, the boss has parallel surfaces spaced apart by the first distance, a boss bore, and a curved rack segment projecting from the boss and configured to mesh with at least a portion of the pinion segment. Also included is a fixing shaft insertably received in at least one flange bore and the boss bore.
