Abstract
A manual agricultural implement, having a shaft with an axis and two ends, a handle arranged at one of the ends of the shaft and a tool arranged at the other end of the shaft having a plurality of tines arranged at radial distances from the shaft, the tines extending around the shaft axis in a curved manner and along the surface of an imaginary cylinder which is coaxial to the shaft axis.
Claims22
A manual agricultural implement, comprising:
- a shaft having a central axis of rotation and two ends;
- a handle arranged at one of said ends of said shaft;
- and
- a tool at the other of said ends of said shaft, said tool having a plurality of elongated tines arranged at radial distances from said shaft, said tines extending around said central axis in a curved manner and along a surface of an imaginary cylinder coaxial to said axis, wherein each of said tines has a base and a body, said base extending radially outward from said axis and said body extending along the surface of said imaginary cylinder, said tine including a transition zone connecting a footpoint of said body to said base, said body terminating in a ground engaging tip, said body defining an arc between said footpoint and said tip.
