2017 - Morbark 3400X Grinder

About this machine

This Morbark 3400X is a used horizontal grinder — sometimes called a tub grinder's inline counterpart or, more commonly, a wood hog — built to process large volumes of wood waste, land-clearing debris, stumps, and organic material into mulch, chips, or biomass fuel. Morbark is a well-established American manufacturer with a long-standing reputation for heavy-duty size-reduction equipment, serving industries including forestry, land clearing, recycling, and biomass production.

Power comes from a Caterpillar C-18 Tier IV-compliant diesel engine rated at 800 horsepower, providing the sustained output needed for demanding, continuous grinding operations. The feed opening measures 57.5 inches wide by 44 inches tall, allowing the machine to accept large-diameter material and bulky feedstock without pre-processing.

The infeed system is 16 feet long and 57.5 inches wide, fitted with a live floor driven by four strands of staggered WDH-120 chain, which meters material into the mill at a controlled rate. On the discharge side, the machine is equipped with both a horizontal conveyor and a stacking conveyor, giving operators flexibility in how processed material is piled or transferred. A magnetized end pulley paired with a collecting slide tray handles ferrous metal removal, protecting downstream equipment and keeping the output stream clean.

The machine is operated via remote control, with a tethered back-up system included for redundancy. Undercarriage is provided by Cat 320L triple-grouser tracks, reported at approximately 80% remaining life. The machine travels at a legal transport width of 8 feet 6 inches and has a working weight of 72,000 pounds. The seller describes it as well maintained and in very good running condition. This unit is available FOB Texas, USA, priced at $459,000.
