The newest model in Morbark’s next-generation platform of horizontal grinders, the 6400XT Wood Hog includes many feature improvements first introduced in the smaller 3400XT, focusing on production, operator-friendliness, ease of maintenance and transportability. The infeed bed is 24 inches (60.96 cm) longer than previous Morbark grinders in the 1,000-plus horsepower range and has sloped sides. This configuration improves operator sight lines for more efficient loading of material. Standard on the 6400XT is a removable infeed chain return floor, which allows excess material to fall away to minimize the wear on the floor, bed chain and inserts, particularly useful in land-clearing or other applications with dirty material.
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 provides an additional 31.5″ (80 cm) of working space for better access for maintenance and changing screens.
Sloped Infeed Sides
Sloped infeed sides and an additonal 24″ (60.96 cm) infeed length gives the operator improved visibililty and loading efficiency.
External Adjustable Break-away Torque Limiter
Flexible, easily adjustable torque limiter helps protect the driveline and hammermill for damage.
