Experience Felling Head - QUADCO 27SC in action. Performance, technology, and reliability in forestry work.

The Quadco 27SC is a disc felling head designed to deliver extreme efficiency in handling and rapidly stacking timber. With an operating weight ranging from 3,493 kg to 3,674 kg (depending on the rotation type) and an impressive cutting capacity of 686 mm, this equipment is the perfect partner for heavy-duty tracked forestry excavators. Its innovative design allows for optimal and rapid stacking, safely processing up to 24 15-cm-diameter trees per cycle.

Large description

Engineering and design: Power and leverage for steep terrain

The Quadco 27SC felling head has been manufactured under the concept of “engineering built for the forest floor,” prioritizing structural strength and the protection of all mechanical components. Its most distinctive feature is an extended high-strength tower that provides superior leverage, giving the operator absolute control and unmatched stability when handling tall timber and logs. The robust chassis minimizes breakdown downtime, translating into superior profitability in the most demanding logging operations.

Accumulation and performance: The power of the “Four Arms Up” system

Productivity in clearfelling operations is defined by cycle speed, and that is where the Quadco 27SC excels. Thanks to its advanced “Four Arms Up” design and a heavy-duty timing bar, tree grabbing and stacking are smooth and automated. The system optimizes hydraulic performance by utilizing a single cylinder per arm set, accelerating the wood collection process. With a massive accumulation area of 2.1 m² over the saw disc, the gathering efficiency per movement is enormous.

Clean and consistent cut quality

The heart of this feller buncher is its powerful 1,651 mm tip-to-tip diameter disc saw, operating at a regulated rated speed of 1,000 rpm. Equipped with 18 teeth and a 61.91 mm cutting kerf, it delivers instant, clean cuts that preserve the integrity of the butt log. Furthermore, operators can choose between one-piece or segmented discs depending on the timber type and terrain, guaranteeing continuous high performance with low field maintenance.

Hydraulic flow and pressure – Requires a continuous working pressure between 3,650 and 4,200 psi (approximately 250 to 290 bar).
Rotation configuration – Available with a 40° partial rotation system (High Torque) or 360° continuous rotation powered by 2 high-performance hydraulic motors.
Recommended base machines – Tracked feller bunchers and construction excavators adapted for forestry use from 25–30 tons.

Frequently Asked Questions (FAQ)

For what type of forest stands is the Quadco 27SC recommended? It is specifically designed for varied timber types and large diameters, excelling in handling and accumulating tall trees thanks to its extended tower that optimizes leverage.
How many small trees can be grouped in a single cycle? Thanks to its wide 2.1 m² accumulation area, the head can process and gather up to 24 trees with an average diameter of 15 cm (6 inches) before dumping.
What advantages does the Quadco 27SC cylinder system offer? It utilizes a single high-capacity cylinder for each set of arms, assisted by a reinforced timing bar. This reduces hydraulic complexity, accelerates opening/closing times, and allows for easier maintenance.
What disc and tooth options are available for maintenance? The 499 kg cutting disc can be configured in either a one-piece or segmented style. It features 18 interchangeable teeth that allow quick sharpening or replacement directly on the forest floor.
Is the Quadco 27SC head compatible with a conventional construction excavator? Yes, provided the excavator has the appropriate tonnage (usually over 25 tons), mandatory forestry guarding, and a regulated hydraulic line that meets the operating pressure range of 3,650 to 4,200 psi.
