For the proper splitting of firewood, a log splitter is essential. Attached to the rear coupling of a SIKU tractor, this device from the Austrian company Posch splits the included plastic tree trunks into two parts in a model-appropriate manner. The movable splitting hammer pulls the trunk into the optimal splitting position via a bracket connected by a chain. The splitting hammer then descends and separates the trunk into two halves. Splittable tree trunks are available as accessories.
