The log splitter screw is a particular tool, used to divide the logs into longitudinal sections; it is used by connecting it to a motor, which rotates it by engaging it on the side of the trunks. The thread on the screw attracts the piece of wood to itself, and the conical shape widens the crack that is created; in this way the logs and trunks are not cut, but split along the grain of the wood. These types of instruments are not very compact, and there are several models, even very cheap. It can be sold equipped with an external electric or internal combustion engine, which operates a hydraulic jack, which pushes and turns the screw. But these large screws can also be connected to external motors, such as the engine of a tractor, or an excavator.
Conical log splitter screw
The conical model itself is a decidedly inexpensive tool; the cost essentially depends on the presence or absence of an engine. When we talk about the screw model, we generally mean the conical one, connected to a motor and to an equipment that facilitates the movement of the machinery: nothing else is needed to split the logs. But the screws can also be sold without motors, supported by a structure that allows them to be connected to external motors. One screw wood splitter it can be very expensive, as the engine that runs it must be powerful; prices are generally above one thousand euros, because they are generally large machines. For hobbyists, on the other hand, models without engine are sold, to be connected to a tractor or a cultivator. In this case we are talking about much cheaper equipment, which often does not exceed 100-150 euros in price.
