How much power (hp) is required for an add-on firewood processor?

The higher the cutting speed and splitting force, the more powerful the vehicle’s drive must be.
For attachment firewood processors with a splitting force of 15 to 20 tons, a vehicle power of 25 hp to 60 hp is typically required. This allows for an average capacity of 3 m³ to 9 m³ per hour.

Usage scenarios

Mobile applications:
When the attached firewood processor is used at multiple locations, the vehicle’s power and weight play a crucial role in stable operation. In addition to the hydraulic properties for machine movement, the vehicle’s lifting capacity also plays a role.

Stationary installation:
In stationary operation, the firewood processor is installed in a fixed location. The required power is primarily determined by the hydraulic power required for the direct controls.

The power versus capacity:

Firewood processors can normally operate at the minimum power requirement. However, more power can also be beneficial. This means you can work and maneuver faster with the attached firewood processors. With BTD machines, the hydraulic oil pressure and flow are automatically limited. This offers the advantage that the machines deliver maximum performance and are always limited to prevent damage. See also Features BTD hydraulic.

Factors that also determine the capacity:

Loading and Splitting Area:
The distance and efficiency of the work environment
Log Length and Diameter:
Larger logs require more force and time
Cutting Length and Wood Type:
The characteristics of the wood influence the speed
Type of Vehicle:
Whether it is a mobile crane, wheel loader, or telescopic handler, the type of vehicle also determines performance

Type of wood

Softwood:
For types of wood such as pine or poplar, a smaller power output is often sufficient. Splitting requires less force because the fibers are more flexible
Hardwood:
For wood such as oak or beech, a more powerful drive is needed. This ensures that the machine continues to operate smoothly and efficiently, even with demanding material

Selection of a suitable machine

Based on the factors above, you can search specifically for an add-on firewood processor that suits your vehicle (including power) and specific needs. Also check Which add-on firewood processor do I need?

BTD Technics offers three models in this context: the PROcompact, PROcompact-S and the PROplus.

PROcompact:
Suitable for smaller vehicles with relatively low hydraulic and lifting capacity
PROcompact-S:
Suitable for smaller vehicles with medium to high hydraulic power and relatively low lifting capacity.
PROplus:
Covering a wider range of requirements, ideal for heavier applications with regard to log thickness, pressing force, and capacity

In short, BTD machines offer a wide range of options to meet the diverse needs and requirements of users.
