A device for breaking loose tree stumps from the ground comprises a vehicle, an arm or the like carried by the vehicle and a tool carried by said arm and engageable with a stump. The tool comprises at least two members movable relative to each other when the tool has been located in an uprooting position relative to the stump. One of said members is adapted to rest against the ground while the tool may lift the stump by means of the relative movement of the members. |
