Product & applications
About the tree shear
A hydraulic tree shear for cutting bamboo, saplings and hedges. Its cutting and gripping mechanism mounts on an excavator for controlled vegetation removal.
Features & benefits
Structural steel
Q355 steel plates form the load-bearing structure.
Wear-resistant cutting blade
An NM400 blade cuts the vegetation. Select the blade geometry and cutting width for the intended material.
Typical applications
- Bamboo cuttingCut bamboo stems within the selected model’s cutting limits.
- Sapling trimmingSelect the cutting width and opening for the size of the saplings.
- Orchard and landscape maintenanceMatch vegetation size, access and the carrier’s working limits to the cutting task.

Excavator identification
Compare the model-specific 2–6, 4–10 and 12–16 tonne carrier ranges.
Mounting connection
Confirm actual pin diameters, centres, clear mounting width and coupler interface.
Hydraulic supply
Compare pressure and oil flow in the table for the selected JY-RLS model.
Cutting dimensions
Check vegetation, opening width, stated cutting width and the machine’s lifting limits.
Product questions
Tree shear questions
Is this a log grapple?
No. This product uses a cutting blade and hydraulic cutting mechanism. A log grapple primarily grips and positions timber.
What vegetation can this series cut?
Bamboo, saplings and hedges within the selected model’s cutting limits. Check cutting width and material before selecting a model.
Does opening width equal cutting width?
No. The table lists both values separately. The space within an open jaw is not itself the permitted cutting section.
Are mounting dimensions in the specification table?
The table gives operating and package dimensions. Confirm the mounting interface separately using the machine and coupler drawings.

Grapples & Material Handling
Rotating log grapple
A hydraulic rotating grapple with curved tines for gripping, positioning and loading timber. Compare jaw opening, attachment weight and the separate hydraulic requirements for rotation and gripping.
Grapples & Material Handling
Hydraulic excavator thumb
A hydraulically operated claw that works against the excavator bucket to hold rocks, logs and irregular debris. Check the thumb length, bucket clearance and mounting arrangement together before selecting a configuration.
