- Model 4800F Series - Chain Flail Debarker



Continuing Peterson’s long history of innovation, this 6th generation design has the features that clean chip operations demand. The Peterson 4800F multiple log delimber/debarker is designed to be used in tandem with whole tree chippers to produce high quality pulp chips. Capable of processing multiple logs from 2 to 23 inches (5–58 cm) in diameter, the 4800F increases productivity while reducing bark content, product handling time, and fiber loss.

Powered by a 350 HP (261 kW) CAT C9 TIER 3 or TIER 4 engine, the 4800F meets all US, Canadian, and European Union emission regulations.

The 4800F features upper and lower flails, direct drive lower in-feed and out-feed rolls, and a floating direct drive upper feed roll. The bark pusher has been redesigned and is now 5 feet (1.5 m) wide.

The machine also features a dedicated 135 gallon (511 l) hydraulic oil tank, and a 175 gallon (662 l) fuel tank to allow the 4800F to run an entire shift without fill-up.

The 4800F is controlled by an IQAN operating system, which provides the operator the information to efficiently operate the unit. The IQAN system provides self-diagnostics for faulty sensors and open circuits, and can communicate complete engine and system parameters.
With a retractable gooseneck, the 4800F is easily moved between jobs and has a curb weight of 42,660 lbs (19 350 kg). The four fixed landing gear (with floating pads) allow the 4800F’s operating height to be adjusted. The operator can operate the machine with a wireless remote which also can pair with the Peterson 5900E disc chipper.

Since 1981, Peterson has specialized in the developing of delivery and processing equipment that turns low-grade organic materials into high value products.
