The short answer
Shear if the timber has value or has to be placed somewhere specific. Mulcher if the material is waste and you are clearing by area rather than by stem. That single distinction settles most of these conversations, and many contractors eventually own both.

Tree shear
Grips, cuts and keeps holding the stem in one motion
Choose it when
- Timber has value and must be stacked, loaded or sold
- Stems must be placed precisely — near buildings, roads or services
- You are thinning to a spec rather than clearing everything
- You are quoting per stem, not per hectare

Forestry mulcher
Reduces standing vegetation to mulch in a single pass
Choose it when
- Material is waste and can stay on site as mulch
- You are pricing per hectare, as fuel reduction and roadside work is
- Stem density is high and stem diameter is moderate
- Nobody needs the timber and nothing needs carting
Side by side
| Criterion | Tree shear | Forestry mulcher |
|---|---|---|
| Unit of work | The stem | The hectare |
| Output | Whole stems, placed where the operator wants | Mulch, left in place |
| Handles valuable timber | Yes — that is the point | No, it destroys it |
| Second pass needed | Yes — stems still have to be processed and moved | No — one pass finishes it |
| Carrier range | 2–50 t | 1–30 t |
| Circuit | Double-acting | Single-acting hammer line |
| Load on the carrier | Intermittent, like normal excavator work | Continuous — pumps, coolers and final drives feel it |
| Dominant running cost | Periodic blade rebuild | Teeth, budgeted monthly in abrasive or stony ground |
Shaded cell is the stronger side on that criterion
When the answer is both
On mixed sites the shear takes the merchantable stems and anything that has to be placed, then the mulcher makes one pass over what is left. Owning both is common precisely because they are not substitutes.
Questions that follow
01Can a mulcher handle standing trees?
Up to its rated diameter, yes — it takes them standing and reduces them in place. Beyond that you are felling first, which is shear or saw work.
02Does a tree shear remove the stump?
No. It leaves a cut stump in the ground. Stump removal is a grinder or cutter job, which are different tools doing a different job.
03Which is better for bushfire fuel reduction?
Mulcher, almost always. Hazard-reduction programs are measured in treated hectares, and area targets favour a tool that finishes in one pass.
