Meet The QS600

Stands Out In Both Performance And Innovative Technology.

The striking QuadStar 600—shown here on a Doosan—stands out in both performance and innovative technology. Ideal for logs 22-26” in diameter, the QS600 features bidirectional drive teeth made for achieving optimal grip, four feed rollers that can handle wide surface areas in multi-stemming, and a durable front knife and sliding mount. 

Here, Cascade Trader puts this attachment to use harvesting, sorting, and delimbing both single and multiple logs as the extended delimb tips make picking up from stacks easy. Side-stepping drive functionality allows for independent control of two stems. The high pressure cylinders pack a punch while the spring link means you can vary multi-stem diameters without losing traction and speed. 

Powerful, durable, and backed by Quadco’s reputation for delivering long-lasting products, the QS600 is a great option for harvesting or road-side processing.


The QS600 is designed for medium to large sized wood with an optimum operating size of 22 – 26″ in diameter. This original large multi-tree processor is packed full of design features that set it apart from the competition.
