An improved raking device comprising extendable rake heads for raking granular material.

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 β=25-45°, the sharpening angle of the teeth is α=20-40°, the angle of rotation of the full penetration of the tooth 3 is γ=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 δ=60-90° to the horizon while minimizing premature soil subsidence, eliminating the need to repeat cultivation of the same plot.

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.

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.

A combination garden tool includes an elongate shaft extending along a central longitudinal axis. The shaft has a first end and a second end. A spade extends along the central longitudinal axis. The spade is attached to the first end of the shaft. A multi-tine cultivator extends from the second end of the shaft, generally orthogonally to the central longitudinal axis. A sickle extends from the second end of the shaft, away from the cultivator.
