The DUXSON FELLING HEAD has been created to bring new levels of performance and reliability to the market.

Professionally designed and constructed, these heads are for the high volume application that demands the best. Huge capacity, quick acting, powerful action and reliable long life are just a few features to improve your throughput.

This versatile attachment suits all applications including fall and bunch for ground based crews or swing yarder grapple, windblown sites – safe for handling fallen or hung up stems, truck and trailer loading, woodlot thinning and sorting and stacking stems.

Construction
  • High Strength Steel. High strength alloy steel is generally used throughout the frame and jaws for long lasting durability.
  • Pins. These are induction-hardened alloy steel. All pin joints also have either heavy-duty hardened steel or high specification plastic bushes— significantly lengthening pin and bearing life.
  • Tight pin tolerances reduce wear and promote long life for the induction hardened pins.
  • All mounting surfaces are precision machined increasing accuracy and reducing uneven loading on mounting bolts. Durability and reliability are greatly enhanced.
Jaws
  • Built Tough. Felling head jaws are made of high-strength alloy steel for maximum durability with the SWITCHBACK™ web feature offering strength in all directions of force.
  • Jaw design is optimised to perform in all areas of loading, sorting, shovelling or bunching.
  • Clamping power is best in class. This improves safety by reducing slippage and reduces the chance of damage to saw bars.
  • Overlapping Jaws. Jaws will close up tight — allowing operators the ability to easily handle single, smaller stems.
  • Wide Opening. Best in class opening widths give the user greater operating flexibility.
  • Wear Shims. Shims are fitted to all high wear areas for reduced body wear, smoother and quieter operation.
Hydraulics
  • 360° Continuous Rotation. High-torque hydraulic motor positions the head precisely for rapid positioning. Built-in cross port relief protects the hydraulic system even with heavy loads. Heavy-duty slew bearing for reliability.
  • Internal Routings. Hose connections and supply lines are protected inside the frame, away from the possibility of damage.
  • Hydraulic Cylinders. All high pressure cylinders are precision made heavy-duty wall construction with heavy duty hardened steel or composite plastic bushes in all pivots. This benefit delivers durability and maximum closing power reliability. Bolted glands offer both durability and serviceability.
  • Rotating seal joint assembly gives unsurpassed seal life with large sealing areas and specialised high pressure seals.
  • Hose layout between head and base machine is compact and neat.
  • Excellent physical cylinder protection with precise hose placement for reduced maintenance.
  • Easy access bar release valve for chain replacement or maintenance.
Saw Bar Assembly
  • Super strong and simple this saw won’t let you down.
  • Fits common bar chain lengths.
  • Large diameter standard saw bar clamping bolts.
  • Saw bar cylinder is mounted away from the chain to prevent premature failure.
  • Saw bar oil lubricates saw bearing with variable oil flow adjustment.
  • Cutting speed is automatically adjusted to suit chain cutting load.
  • Infinite cutting and retraction speed adjustment.
  • External flag indicates when bar is home.
Serviceability and Product Support
  • Access Panels. Bolt-on access panels protect the internals, but allow easy serviceability in the field.
  • In-the-Field Servicing. All grease points, motors and other serviceable components are easily accessible in the field with standard hand tools. Service can be performed quickly, from one position, minimizing downtime.
  • All common spare parts are available ex stock for same day dispatch.
  • Standardised fit up with various setup options and links available.
  • Optional hose through or non-hose through rotators.
