Tree clearing

Tree clearing. In many cases, after cutting down or destroying trees, it is necessary to remove their stumps, ie grubbing up.

Traditional grubbing-up requires a lot of work and the use of equipment with high lifting power. In order to remove a stump, it must be dug, and trim the roots. Then the stump is pulled out with a grubber, tractor, crane or similar devices. Forest grubs produced in Poland have a lifting force of up to 8 your. In forestry, explosives are used to clear up. This method in urban conditions is severely limited due to safety and the required silence. A convenient way is to remove the tree along with the stump. For this purpose, a rope is tied on a trunk at a height of several to several meters, then the tree is knocked over with this rope, e.g.. by the tractor. The part of the trunk serving as a one-sided lever should not have weakened places - mainly large wood losses. Smaller trees with flat root systems can be cut in this way without entrenching. In compact soils, it is often necessary to undercut these roots, which are stretched during grubbing up.

Often, when clearing and felling together with a stump, a stable anchorage point is needed. It can be a different stump or a special anchor, however, never use an adjacent tree for this purpose.

In some cases, grubbing up should be abandoned not only for reasons of economy, but also ecological. The decaying root system of the stump left behind improves the soil structure, creates ventilation channels and enriches the soil with organic matter. In addition, leaving stumps on the slopes prevents erosion. Often, stumps from low-cut trees are not removed. To cut down a tree like that, they should be previously dug up and the pockets formed by the root runs removed from stones and soil. The tree is cut down flush with the ground or even lower. For this purpose, special motor cutters are used.
