Max. log diameter

The largest log diameter that a log splitter can handle.

This parameter depends both on the size of the working nozzle and the “seat” for the workpiece, and on the splitting force. Usually, it is indicated per log of maximum length (see above). However, this does not mean that with a shorter length of the workpiece, it can be thicker than stated in the specifications — anyway, it is not recommended to work with too thick logs, i.e. the tool may experience undesirable loads. As for specific values, the maximum thickness of up to 30 cm is typical for wood splitters mainly for domestic purposes, more than 30 cm for powerful professional units.

Max. power

Wood splitter motor power in watts. The designation in watts is used for all types of engines, which allows you to compare units with different types of motors.

A powerful motor is needed above all in order to provide a high splitting force (see above). However, when choosing, it is worth focus not so much on power, but on the force stated in the characteristics and the length / thickness of the logs. In addition, in the case of electric motors (see "Motor type"), the power directly determines the energy consumption, which is important in some situations (when running from a generator, with weak wiring, etc.)

Protective box

Models that are equipped with a protective box that prevents the log from falling apart and the logs falling down after it is split. It is designed to stop chips and logs that can scatter in all directions under the pressure of the knife. Often, a protective box is created from perforated sheet metal. Thanks to the perforation, the wood splitter operator can visually control what is happening in the working area. Most often, the protective box is installed on wood splitters with a horizontal log arrangement. In such models, when chopping firewood, the wood can literally “shoot” forward, which can be dangerous. And in vertical wood splitters, wood chips always just fly down, which in itself is absolutely safe.
