Depending on the field, the wood chipper can also be called a splitter, splitter or even saw for firewood; and this to refer to the same tool: the one that serves to divide your logs or timber.
The wood chipper, therefore, is reserved for professionals who develop a logging activity or for individuals who have a heating system such as a wood boiler, an insert, etc.
Able to split any trunk lengthwise, the chipper replaces in practice the ax as well as the entente formed by the club and the wedge.
What are the different types of wood chippers?
Depending on your garden job more specifically on the amount of cubic meters of wood that you need to split every year, you can choose between three types of chipper for you:
- Electric wood chipper;
- Thermal wood chipper;
- Hydraulic wood chipper.
Electric wood chipper
The electric motorized is recommended for users who have an approximate consumption of 10 m3 of firewood every year; Electric chippers are practical because of their energy, non-polluting and low noise. Capable of splitting logs up to 40 cm in diameter, its fixing cylinder can reach 10 tons, being 5 tons (T) the minimum, corresponding to logs of 30 cm. Its power varies according to its intrinsic characteristics and is between 1,500 and 3,500 watts (W).
Thermal wood chipper
Destined to individuals or professionals with a work volume of more than 12 m3 per year, the thermal chippers are designed for intense activities and offer much higher power thanks to its 4-stroke engine. Its initial thrust is approximately 11 tonnes (T) for a power (P) of 5.5 horsepower (cv), ie 9000 W. The most powerful develop up to 22 T and cut logs up to 60 cm in diameter.
Hydraulic wood chipper
Conceived to work connected to the end of the shaft of a tractor, the hydraulic wood chippers are often used (evidently) by those who own this type of agricultural vehicles. Its initial thrust is about 11 T (logs approximately 35 cm in diameter). They can reach very high powers; they are robust and reliable machines that guarantee a work volume of more than 12 m3 per year.
Finally, if you require heavy garden job & plan to have best commercial wood chipper then you should either choose thermal or hydraulic power chippers. So that you can do your job in a large amount.
Wood chipper: vertical or horizontal?
Regardless of the engine we have, a wood chipper can be vertical or horizontal. Let’s analyze these two provisions:
The advantage lies in the fact that this slitter is equipped with a table in which the log is placed. The drawback is that you have to settle it, which entails something more manipulation. Suitable for splitting logs less than 50 centimeters long and whose diameter is small.
The handling is smaller and its use is preferable for large diameter logs that exceed 50 cm in length. The split types often have a guide to keep the trunk well placed.
What other features to value in a wood chipper?
Once your consumption and / or production of wood is calculated per year, after evaluating the size of your logs (length and diameter) and consequently knowing what power and thrust your wood chipper needs, you are in a position to apply these selection criteria:
- the duration of the cracking cycle consists of the duration of the going and the return;
- the size of the wedge to crack;
- the different cracking heights, if it is a vertical chipper;
- the speed of advance (a data very similar to the duration of the cycle);
- the number of decibels (dB) (especially for 4-stroke engines);
- the towable option for thermal models;
- if the table can be tilted, in the case of horizontal chippers;
- the solidity and the finish of the chassis;
- the weight of non-towable electric models;
Other specific characteristics are indicated in the technical specifications of the manufacturer, such as the hydraulic oil capacity (referring to the size of the cylinder), its type (viscosity), the material of the chassis (normally made of epoxy coated steel), although these data are not as important as those listed above are.
