ABSTRACT:
A forestry machine with devices for felling, trimming and cutting trees includes a control system with operating devices which are actuable by an operator. The operating devices control the felling, trimming and cutting devices, as well as the movements of the forestry machine. The operating devices are disposed discrete and separate from the forestry machine so that the working environment of the operator is free of the turnings, jolts and vibrations which the forestry machine is subjected to during operation. Preferably, the operator and the operating devices are placed in a load-carrying vehicle on which the forestry machine loads the felled trees. A system for forest felling includes a felling unit and an operating module. The operating module is disposed discrete and separate from the felling unit. Preferably, the operating module is disposed in a load-carrying vehicle which receives felled trees from the felling unit.
