Overview

The 6440 is a high horsepower drum chipper. Designed for high production and high uptime, the 6440 employs a through-drive and belt system to turn the rotor, eliminating the need for clutches.

Through-Drive Rotor System

The rotor drive belt is driven off of the engine using a flex drive coupling and drive adapter. The engine base extends and retracts to
engage or disengage the drive belts eliminating the need for a clutch.

Chip pockets are lined with replaceable wear plates.

Excellent Service Access

Platforms and steps are located around the machine at maintenance and service areas such as the engine air filters, hydraulic oil filters, and fuel fill. A centralized service area in the centre of the machine allows access to hydraulic components, electrical components, and engine filters.

High Output Discharge

The discharge chute is angled at 25° to allow for high volume output without the need for a chip accelerator. An optional chip accelerator is available for micro chip applications.
