The stump removing machine was invented to carry out the work of extraction and destruction of tree stumps in an easy and quick way.
THE PROBLEM TO BE SOLVED
When the tree is cut and fallen down the stump remains in the ground. In order to reuse that ground for new cultivations, it is necessary to remove or destroy the stump. The machine can be used with the cylinder or with the drill.
The cylinder is hollow and is bolted at the base of the machine and then it is made turn on the stump; the cylinder has a crown wheel on its bottom and therefore it cuts the stump roots and the ground all around it. After the work the machine lifts the cylinder containing the extracted stump; the last phase consists in the ejection of the wooden stump from the cylinder, to make it ready for work again.
This is the tool to be assembled on the base of the stump-removing machine that allows to completely destroy the stump leaving its fragments in the ground. It consists of a drilling device that bores the stump in the centre and two knife blades that cut the whole wood and the roots that branch off the stump itself. At the end of the operation the wood will be inside the ground but totally crushed, so that the ground can be worked without difficulty.
These tools (drill and cylinder) are interchangeable and are supplied on demand.
The machine must be taken next to the stump to be removed. The position is centered by bringing the tool down on the stump with the machine in the non-rotation mode. You have the tool spin and push it to the bottom. At this point the machine is lifted and the rotation stopped. If you are using the cylinder, the wood can be expelled from its inside with the jack provided. The operation is finished.
The time necessary for a working cycle is just one minute.
