The newest tree shears and grapples for excavators

Fixed-knife Tree Shears with Unique Features

The new Mastergrapple series with the largest grapple opening, unparalleled for grappling stems by bunch and wood handling.

Extra sturdy for use on excavator, its frame and grapple made of Hardox, mistreated during the test phase to reach the best quality and reliability.

The knife it detachable in a minute, for switching to wood handling, or for demolition tasks after the harvesting season.

2 models: MG260 and MG320.

Why Mastergrapple?

It’s the new concept of excavator-grade grapples, aimed to be as multifunctional as possible, for the use in forest and other seasonal tasks. One grapple as master, several accessory modules, to cover a wide range of jobs.

In forest harvesting, the CPR9 rotator is real efficient, very fast and very decent at holding trees, even though it has no break. It makes to wood handling so much better, particularly with such a large grapple opening.

That's the fast rotator kit in action on the MG260. It makes the large grapple opening (147 cm) even more useful. The knife is detachable in 1 min and the grapple can be used for any material handling. @baltrotors_com #baltrotors #biojack #biokackgrapples #mastergrapple #hardoxinmybody #treeshears #energiakoura #trädklipp #baumschere #cisaille #energywood #energieholz #boisénergie #metsäkoneet #materielforestier #grapple #grappin #kahmari #grip #greifer #madeinfinland

The accumulation grapple (E-kit) speeds up the energy wood picking, and we were running it with the MG260. 🌲💪🇫🇮 Here it works automatically: one grapple opens when the other closes. For dropping the stems on the ground, there's a radio command to open both grapples together.
