Wood heads

NAARVA accumulating energy wood heads - E models

Three frames, four guillotines, and four accumulating grapple options provide a wealth of choice: a total of twelve different combinations. E models are suitable for small wood, energy wood harvesting, first thinning, clearing on electricity and gas lines, road and railway sides. The unique sliding guillotine, cutting against the grippers, ensuring that all stems in the bunch are cut through.

All Naarva accumulating energy wood heads can be used for loading since the guillotine does not interfere with loading when it is fully open. Easy to install, compatible with control systems of most base machines. Naarva radio control is available as an option and facilitates installation without a boom cable and plugs. Radio control also allows free rotation of the grapple, which contributes to ease of working.
