Where to buy

Innovative and engineered for the toughest applications, the HTH622C 4x4 harvesting and processing head provides peak performance, productivity and uptime.

This head features a four-roller design for single harvesting/processing or multi-stem processing applications. Automatic dual stem and end alignment allow for fast processing and minimal waste.

This heads's auto-tension 3/4 pitch main saw with 65 cm (26 in.) cutting capacity offers extra efficiency, longer chain life and fewer service intervals. A high-flow hydraulic valve contributes to faster feeding and saw performance.

Loggers can experience extreme accuracy with dual diameter- and length-measuring innovation. Plus, the 360-degree continuous rotation helps improve log handling, reduce carrier-to-head hose failures and lower operating costs.
