## Abstract

The disclosure relates to a harvester (10) for harvesting logs. The harvester comprises a traction arrangement (11) configured to drive the harvester, an articulated boom (13) configured to connect to a processing head, a fuel reservoir, an electrical energy generator fueled by a fuel from the fuel reservoir and configured for supplying power to the traction arrangement and the articulated boom, and an electrical connector (17) configured for coupling the electrical energy generator to an electrical energy storage of a shuttle. The harvester is configured to load a harvested log onto a coupled shuttle and charge the electrical energy storage of said coupled shuttle using electrical energy from the electrical energy generator.

## Claims
