Independent attachment selection guide
Felling Heads
Felling heads are forestry attachments built to grip and sever standing stems. Depending on the design they may cut one tree at a time, accumulate several small stems, or combine felling with limited handling before the timber is placed for processing.
Quick answer: Best suited to mechanized felling where stems must be controlled at the cut and placed in a planned direction or bundle. The main reason to choose another attachment is when full cut-to-length processing when delimbing, feeding and measuring are required in the same head.
What are felling heads?
In practical terms, felling heads are selected when the job calls for mechanized felling where stems must be controlled at the cut and placed in a planned direction or bundle. They are not simply another name for a neighboring attachment family: the working geometry and duty are different.
You may also see this attachment described as forestry felling head, tree felling attachment, accumulating felling head. Terminology varies by region and manufacturer, so compare the working principle, mounting geometry and rated limits rather than the product name alone.
This felling heads guide is manufacturer-neutral. Use it to build a shortlist and a technical question list, then confirm the exact fit and safe operating limits from the carrier and attachment documentation.

Common types and configurations
Single-tree felling head
Grips and cuts one stem at a time, keeping the mechanism comparatively simple.
Accumulating felling head
Adds arms or pockets that can retain several small stems before placement, which can improve productivity in thinning or biomass work.
Felling head with rotation
Rotation helps orient the head and place stems, especially when mounted on excavators or carriers that work around obstacles.
How to choose the right setup
- Stem range
- Use the manufacturer cutting range and grapple geometry for the species and diameter expected on the site.
- Cutting principle
- Disc saw, bar saw or shear systems have different cycle characteristics, maintenance needs and cut behavior.
- Accumulation capacity
- For small stems, accumulation can reduce placement cycles but adds weight and operating complexity.
- Carrier hydraulics
- Cutting, gripping and rotation may have different flow and pressure demands. Check simultaneous function requirements.
- Boom and guarding
- Forestry work exposes the carrier to falling limbs and debris; the complete machine setup may need forestry guarding and hose protection.
For felling heads, carrier weight is only a first filter. Pay particular attention to stem range, cutting principle and the complete attachment mass. Mounting height, center of gravity, working radius and the material being handled can change the load on the carrier substantially.
Carrier, mounting and hydraulic compatibility
Typical carrier groups for felling heads include forestry machines, excavators. Start with the exact machine make and model, then verify the approved coupler or pin geometry, attachment mass and working envelope. If a quick coupler, tilt unit, rotator or adapter is added, include it in the total geometry and weight calculation.
For powered felling heads, compare the required auxiliary flow and pressure with the carrier’s continuous capability, not just the maximum headline figure. Confirm return-line, case-drain and electrical-control requirements where applicable. A physical connection is not proof that the complete hydraulic and structural configuration is approved.
Practical operating approach
- Approach the stem so the grapple can control it before the cut is completed.
- Plan where the stem will move after separation and keep the machine outside the expected fall path.
- Place or accumulate timber without overloading the head or boom at long reach.
With felling heads, machine position is part of the attachment setup. Work from a stable stance, keep the highest loads as close to the carrier as the task allows, and avoid unnecessary side loading. This improves visibility and reduces leverage through the coupler, boom and attachment frame.
Limits and safety checks
- A felling head does not automatically provide delimbing or measuring.
- Accumulation is useful mainly where stem size and site method suit multi-stem handling.
- A head sized by cutting diameter alone can still be too heavy or hydraulically demanding for the carrier.
The limits for felling heads are model-specific and apply only to the conditions stated by the manufacturer. Combine the attachment instructions with the carrier manual and local site rules, and use an exclusion zone whenever the work can create falling, swinging, rolling, rotating or ejected material.
Maintenance and wear points
- Inspect cutting tools, grapple pivots, accumulation arms and guards for damage.
- Check hydraulic hoses and rotator connections where repeated twisting or stem contact can occur.
- Maintain saw lubrication, blade condition or shear edges according to the specific cutting system.
A short pre-shift check is particularly useful on felling heads because the working components are exposed directly to the material and environment. Record abnormal play, cracks, heat, leaks, bent components or unusual noise early rather than treating them as normal wear.
Compare related attachments
- Grapple Saws — combine gripping and sawing but are often simpler than dedicated felling heads.
- Tree Shears — offer a direct shearing approach for vegetation and stem removal.
- Forestry Mulchers — process vegetation in place instead of felling stems for handling.
If felling heads are only one option for the job, use the attachment directory to compare adjacent tool families. You can also start from the machine-type guides or the application guides when the carrier or job is already fixed.
Before requesting a quote
- Write down the carrier make, model, operating weight and coupler or pin dimensions.
- Record auxiliary flow, pressure, return and electrical connections available on the machine.
- Describe the material, expected duty cycle, working environment and the most demanding part of the job.
- Ask for attachment weight, dimensions, rated limits, hydraulic requirements, wear-part list and service intervals.
- Confirm how the attachment changes machine stability, visibility, transport width and working envelope.
Common questions
Felling head or harvester head?
A felling head focuses on gripping and severing stems. A harvester head usually adds feeding, delimbing and measuring for cut-to-length processing.
What is an accumulating felling head?
It can hold more than one smaller stem before placement, helping reduce repeated boom movements in suitable thinning or biomass work.
Can an excavator use a felling head?
Yes, many felling heads are offered for excavator-based carriers, but boom geometry, guarding, hydraulics and stability must be checked for the complete setup.
How this guide should be used
This page places felling heads inside the MachineAttachments.com tool, carrier and application directory. It is an independent selection overview rather than a compatibility approval, product review or substitute for a manufacturer manual. Because model-specific dimensions, interfaces and ratings can change, verify the current technical documentation before ordering or operating equipment.
