Chop down the spruce and determine the weight
When a spruce in the garden or directly on residential buildings has grown too big or is no longer healthy grows and poses a danger to the environment, the spruce should be felled professionally prepare. It is important to ask in advance whether a permit is required and what technique the tree can be felled with, and you should also determine the weight of the spruce.
What you need:
- chainsaw
- Chainsaw driving license
- Tape measure
- Lifting platform or lifting crane
The permit to fell the spruce
- In order to be absolutely sure whether the felling of the spruce requires a permit, you should inquire at a gardening specialist or the forest farmers' association.
- As a rule, the felling of trees with a trunk diameter of 10 centimeters or more, measured at a trunk height of one meter, is subject to approval. The experts can not only explain the conditions from which trunk size a permit has to be applied for, they also give comprehensive advice on felling the tree itself.
The right technical equipment
- The technical equipment of professionals offers security when felling in a residential area. Do not cut down large trees without professional help. Usually there is not enough space to fall, and the exact direction of the fall can rarely be predicted. A lifting platform or a lifting crane is necessary to prune and remove trees piece by piece. This enables safe felling, the trunks and branches do not fall down in an uncontrolled manner.
- For chainsaws is a Chainsaws- Driver's license required, without it you are no longer allowed to work.
Determine the weight of the spruce
- Determining the spruce weight is important for the working method, with which the tree is cut as a whole close to the ground and has sufficient fall space. The spruce weight must also be determined for the utilization of the wood.
- Fresh from the forest, i.e. freshly cut, spruces weigh around 850 kilograms per cubic meter of wood. The solid cubic meters can be calculated using the formula: mean tree diameter x trunk length times pi divided by 4. The mean tree diameter is also measured exactly in the middle of the trunk.

Felling the spruce
- Depending on the planned working method, the tree is cut close to the ground and tied into one with wedges and ropes guided in a certain direction of fall or removed by means of a lifting platform and chainsaw and fall to the ground piece by piece calmly.
- When the trunk is on the ground, limed and pitted, measurements are taken. The mean trunk diameter provides the basis for calculating the spruce weight. The formula can be used to determine the solid cubic meter content and thus also the price for the wood.
