A weed puller that comprises a plurality of prongs positioned about an axis, an anvil plate, and a moveable mass adapted to be driven into the anvil plate so as to transmit a force through the anvil plate to the prongs where the force has a substantial component in line with the axis about which the plurality of prongs are positioned. In a preferred embodiment, the weed puller comprises a body having a cavity that terminates at the anvil plate with the moveable mass slideably positioned within the cavity and the moveable mass being coupled to a rod that extends out of the cavity from an end opposite the anvil plate.

A gardening tool extracts a weed along with a plug of soil. A plurality of blades are circumferentially spaced about an axis of a shaft and extend downwardly beyond the lower end of the shaft for insertion into soil about the roots. Each blade includes a trailing edge and a leading edge that leads the trailing edge during rotation in a selected rotational direction about the axis. An ejector body is positioned between the blades and is axially movable from an upper position to a lower position to eject soil from between the blades. An ejector control member at least substantially surrounding the shaft is axially movable by hand. A plurality of connecting members are circumferentially spaced about the shaft and connect the ejector control member to the ejector body, such that axial movement of the ejector control member causes axial movement of the ejector body.

This invention provides a post hole digger having a first, traverse pivot point, located on the medial portions of two handle members, and a second, blade assembly pivot point located at the medial point of the blade assemblies. Because the first pivot point is a traverse pivot point, the handle members are only required to travel through a limited range of motion. Additionally, the second, blade assembly pivot point is preferably an offset pivot point. Thus, because the second, blade assembly pivot point is disposed at a medial point of the blade assemblies, the motion of the handle members, which are coupled to the upper ends of the blade assemblies, is reversed relative to the lower ends of the blade members.

The invention discloses an electric weeding machine, which comprises a driving device, a working head, a connecting rod and a main handle, a push-off handle which can move relative to the connecting rod and a push-off baffle which can move relative to the working head, wherein the driving device is arranged in the main handle or between the main handle and the working head; the push-off baffle moves along the push-out direction of grass under the action of the push-off handle; and the push-off handle is connected with the push-off baffle, and the push-off baffle can rotate in the push-off handle. Compared with a manual weeding machine, the electric weeding machine has the advantage that the weeding efficiency can be improved effectively and is improved by one time; the driving device is arranged on the push-off handle or between the push-off handle and the working head and is close to the working head, so the sway of the working head during operation is reduced effectively, and the operating comfort level is improved; a grass push-off structure is simple, namely the grass push-off operation can be completed only by the push-off handle, so the grass push-off structure is convenient to operate and high in efficiency; and the push-off handle is arranged on the connecting rod and does not rotate with the rotation of the working head, so the output power of the driving device is reduced.

A cultivator includes an operation rod and at least one fixing seat. The operation rod includes a predetermined number of detachable rotary wheels at a predetermined position. The fixing seat is pivotally connected to the operation rod. A predetermined number of cultivating claws are pivoted on a circumferential portion of the fixing seat at a predetermined angle and position after being assembled. Through the rotary wheels or the cultivating claws, the cultivator is turned left and right or back and forth to loosen soil.

This invention provides a post hole digger having a first, traverse pivot point, located on the lower section of two handle members, and a second, blade assembly pivot point located at the medial point of the blade assemblies. Because the first pivot point is a traverse pivot point, the handle members are only required to travel through a limited range of motion. Additionally, the second, blade assembly pivot point is preferably an offset pivot point. Thus, because the second, blade assembly pivot point is disposed at a medial point of the blade assemblies, the motion of the handle members, which are coupled to the upper ends of the blade assemblies, is reversed relative to the lower ends of the blade members.
