QS605 Grapple Processor

Watch as the QS605 Grapple Processor grabs, sorts, and measures logs; effortlessly delimbs; handles several logs at once; and operates on steep BC terrain with its twin rotating motors. Ideal for 22 – 26” trees, the QS605 combines the functionalities of a grapple and process machine with that of a multi-stem processor, bringing you decreased downtime and long-lasting support. 

Big Horn Logging operators demonstrate the QS605’s wide frame structure, designed for reduced frame cracking and improved hose routing, as well as its unique side stepping drive that allows for independent control over two stems. Its grapple arms feature extra-limb capacity while the powerful 4×4 drive provides the torque you need for large wood–plus the processing ability to handle multiple smaller stems at once. 

The QS605 also features the best in updated technology: magnetic touch-less encoders mean better accuracy and longer machine life while tilt-leveling software allows for better log control when handling wood off-center.


The QS605 grapple processor is designed to be able to sort, shovel and load like a grapple and process and measure and cut with all the advantages of a Southstar processor. Combine your loading and processing into one effective machine. The QS605 is designed for medium to large sized wood with an optimum operating size of 22 – 26″ in diameter. This large multi-tree grapple processor is packed full of design features that set it apart from the competition.
