Forestry in big scale is heavy work that requires heavy machinery. Generally you have a timber harvester, which is an all-terrain vehicle and will have a chain-saw to cut the tree at the base and it has delimbing knives that cut the branches, for the cutting process you have feed rollers that forces the log through, while the knives limb the tree.
After the threes have been cut a skidder, another heavy machinery, drags the logs to the central collection point called the landing. The skidder can have rubber tires or have tracks, usually a quarter mile distance, limited to slopes of 30° or less if they are with rubber tires and up to 50° if they are tracked.
Difference of how they pull the logs. Cable or grapple Cable uses a cable with chokers that are attached to the log and the log can then be dragged out from the area where it was cut, the skidder doesn’t have to get that close. A grapple has steel claws that can grip a number of logs and maneuver around areas.
Once all the logs are collected at the landing they can be lifted onto trucks and driven to a sawmill or paper mill. Logging trucks can be divided into ones that are used within the forest closer to where the trees are felled and need all-terrain properties and those who are more just used for highway transport. The all-terrain has high both suspension and tire requirements to be able to handle the rough terrain. To achieve good traction in addition to good tires, you can see trucks with up to 9 axles. This is both to get better traction though the number of good tires as well as low ground pressure, which reduces the footprint in the forest.
The best time to cut down the trees is late winter, early spring. This means that the weather conditions can be quite challenging for these equipment to get there. You will need very sturdy and rugged tires that can handle both mud and snow. You need excellent steering abilities as you maneuver through rough terrain and great driving stability from the tires. The tires need to be able to carry extremely high loads and need to have excellent traction to enable to drag the logs, without slipping. Special skidder tires and harvester tires that are part of the heavy tire assortment is a must to ensure low down time and good service life.
