Felling head MD series

Product overview
The Tree Shear Grapple is a hydraulic cutting grapple designed to cut and hold trees, bushes and branches while mounted on excavators and carriers. Constructed from wear-resistant steel, it combines a patented dual-blade cutting system with an enclosed drive for operator safety and reliable field performance.

Tool functions

• Cutting trees, branches and bushes
• Field, forest and overgrown land clearing
• Greenery pruning and shrub clearing
• Riverbank and riparian vegetation cleaning

Smart modular concept
The grapple is compatible with a modular upgrade system offering over 100 additional functions. Modular upgrades allow quick adaptation to different tasks and extend the operational capability of the base unit.
