An adjustment assembly configured to be coupled with a longitudinal support assembly of a cultivator assembly is disclosed. The adjustment assembly includes a swing arm rotationally coupled to the longitudinal support assembly, a first gang unit rotationally coupled with the swing arm and a second gang unit spaced apart from the first gang unit and rotationally coupled with the swing arm. A first gang adjustment mechanism rotates the first gang unit with respect to the longitudinal support assembly and a second gang adjustment mechanism rotates the second gang unit with respect to the longitudinal support assembly.

The invention relates to agricultural manual implements with teeth, particularly to operating elements of hand cultivators.

The operating element 2 of the cultivator 1 contains distributed spiral teeth 3, forming an open circular profile 4 in the plan. The spiral teeth 3 are connected in the upper part to each other in the shape of a regular polygon 5, while the pointed part 6 of the spiral tooth 3 smoothly passes into its remaining cylindrical part 7. The tilt angle of the spiral teeth 3 to the horizon is =25-45, the sharpening angle of the teeth is =20-40, the angle of rotation of the full penetration of the tooth 3 is =40-120, and the thickness of the cutting edge 7 of the spiral tooth 3 is h=1-3 mm. The invention allows to reduce the fatigue of human muscles during loosening due to easy penetration of the operating element 2 of the cultivator 1 into the soil when it is installed on the soil at the angle =60-90 to the horizon while minimizing premature soil subsidence, eliminating the need to repeat cultivation of the same plot.

An animal waste rake or barn stall rake that separates waste from animal bedding such as wood chips or straw. The manure rake or barn stall rake apparatus of the invention includes a shaker assembly that both vibrates and shakes the manure basket of the rake to expeditiously separate the manure from the bedding.

A digging fork has a shaft at an end of which extends in a row first, second, third and fourth tines. The second and third tines are angled towards each other to form a wedge shape and the first and fourth tines are substantially parallel to each other.

A hand tiller has an elongated handle with a left tiller wheel and a right tiller wheel coupled to an axel and configured to rotate about the axel to till the ground. Each of the tiller wheels has a plurality of tines that have a curved geometry, wherein the tines curve circumferentially toward the extended end that is paddle shaped to more effectively penetrate the soil and lift the soil while tilling. Also, the tines taper toward the connected end. The tiller wheels are retained on the axel by tiller wheel retainers that couple with the axel, such as by being threaded into or onto the axel. The handle extends a handle length from the handle-end to the axel-end. The handle has a thumb flange on both the top side and bottom side to provide a resting place for a person's thumb when operating the hand tiller.

Embodiments are provided for a garden hoe that is made up of a head member that has a first point section, an intermediate section that is capable of forming an acute angle and attaching to an elongated handle, and a second point section. In one embodiment, the first point section is offset from the intermediate section, and the second point section is offset opposite to the first point section from the intermediate section. The first and second point sections further have a plurality of V-shaped notches and a plurality of V-shaped points.

A jumping pit raking assembly includes an elongated member having a first lateral edge, a second lateral edge, a front side, a rear side and a bottom edge. A sand engaging member is attached to the elongated member and extends downwardly from the bottom edge. The sand engaging member engages sand such that the sand is smoothed as the sand engaging member being moved across the sand. A pair of carriages is provided and each includes an end panel having an interior side and an exterior side positioned opposite of each other. A first wheel and a second wheel each is rotatably coupled to the end panel and extends downwardly therefrom. A handle coupled to the end panel.
