Key Features & Specs
Listening closely to customer feedback while developing the design for the 3400X Wood Hog, Morbark provides the features customers want and the versatility they need, while staying true to our proven technology. One of the most important features of the 3400X is that it can be made as narrow as 8’4″ (2.53 m), making it within the legal transport width in any country, no matter what engine is used. This model accommodates engines from 520 to 800 horsepower (388 to 596 kW), so it is ideal for a broad range of applications in a wide variety of markets worldwide. Like all of Morbark Wood Hog models, the 3400X also is available with electric power. The size of the 3400X allows the same model, using a broad range of engines, to be configured for multiple applications and global markets without additional design considerations.
  • Sloped Infeed Sides - Sloped infeed sides and an additional 24″ (60.96 cm) infeed length gives the operator improved visibility and loading efficiency.
  • Externally Adjustable Break-Away Torque Limiter - Flexible, easily adjustable torque limiter helps protect the driveline and hammermill for damage.
  • Feed System - Internal planetary drive with no chains and sprockets means lower maintenance, more torque and better durability.
  • Morbark Integrated Control Systems (MICS) - Automatically adjusts feed rates and monitors pressures and feed wheel position to maximize production and engine efficiency.
  • Extended Maintenance Platform - The area between the hood and the engine has been reconfigured to provide an additional 12 inches (30.48 cm) of working space, for better access to components for general maintenance or to change screens.
