Tool for soil cultivating machine, and machine using such tools

A device for a soil cultivating machine, comprising:

• a rotor adapted to be rotatably mounted to the soil cultivating device;
• a plurality of tools interchangeably mounted on the rotor;
• each of the plurality of tools comprising a fixing end, a soil engaging portion, and a connecting portion which connects the fixing end to the soil engaging portion;
• each fixing end comprising a ring portion which is freely movably mounted to the rotor via an axle;
• each soil engaging portion arranged below the ring portion and comprising a plate like member having a leading edge;
• and
• a mechanism that applies a spring force against the ring portions of the tools such that the ring portions of the tools are biased against the rotor,
• wherein the ring portions of the tools are arranged between the rotor and the mechanism, and
• wherein each of the axles are oriented at an angle relative of a center axis of the rotor.

A tool for a soil cultivating machine having a rotor, the tool comprising:

• a fixing end comprising an upper space zone, a ring adapted to receive a journal axle, and a pivot axis;
• the fixing end being adapted to be pivotally and removably mounted to a rotor about the pivot axis;
• a connecting portion comprising an intermediate space zone which extends downwardly from the fixing end;
• and
• an active portion comprising a lower space zone and an approximately planar portion having a sharp leading edge,
• wherein the active portion projects towards a direction of rotation of a rotor when the tool is installed on a rotor,
• wherein the fixing portion extends from an upper end of the connecting portion and wherein the active portion extends from a lower end of the connecting portion, and
• wherein the fixing portion extends from one side of the connecting portion and wherein the active portion extends from another side of the connecting portion.
