Harvester (forestry)

A harvester in forestry is like a special machine that helps cut down and gather trees in huge forests. It has big arms called harvester heads with very sharp circular saws or chainsaws on them. The harvester can grab the tree with these arms and cut it down. Then, it starts removing the branches, leaves, and bark from the tree by shaking it really hard. The tree trunk is then cut into smaller pieces and collected in a container attached to the harvester. The harvester can even separate the different parts of the tree, like the trunk and branches, and put them in different containers. It's like a giant robot that works really fast and can do the work of many people at once!
