Vermeer continues to innovate with the introduction of the redesigned HG4000 horizontal grinder. This new generation of the HG4000 delivers powerful performance in a variety of wood waste recycling applications. It’s equipped with a 399.7-kW (536-hp) CAT C13B Stage V/T4F diesel engine, a Series III duplex drum, improved infeed to better accommodate a variety of materials, and many performance and durability upgrades. It’s quieter, too, with a working sound level of 112 dba.

According to Vermeer Product Manager for Environmental Equipment Jeff Bradley, the HG4000 horizontal grinder is a popular model in Europe because of its powerful performance, transportability and versatility. “This new generation of the HG4000 builds upon those qualities with more robust components and a powerful engine to produce an even better on-the-job performance and enhanced serviceability. The new HG4000 is optimized for compost operations, biofuel producers, land-clearing crews, tree service specialists and municipalities alike.”

The HG4000 has a feed table capacity of 3.5 cubic meters (4.6 yd3). It features the proven cutting performance of the Vermeer patented Series III duplex drum with reversible hammers and tips for nearly double the wear life of single-sided designs. The new hard-faced anvil on the HG4000 delivers impressive cutting action with the drum, and a redesigned anvil-mount structure helps simplify the hard-faced wear edge replacement process.

The HG4000 benefits from a new feed roller with aggressive teeth and down pressure to maintain control of the fed material. A fully enclosed feed roller drive planetary provides protection and a tighter clearance between the roller and mill housing to improve material feeding.

A wireless remote control comes standard with the HG4000, allowing operators to run most machine functions from up to 91.4 meters (300 ft) away. “With the remote, operators are able to adjust infeed settings, engine speed droop, conveyer height and more, which means more time grinding throughout the day,” explained Bradley.

The redesigned Vermeer HG4000 incorporates several services and maintenance enhancements, including a drive belt tensioning system that does not require the engine to be moved when adjusting, large hinged side shields for better maintenance access, added power rotation to the screen hoist for changing screens, and a CAT engine with worldwide support. It can also be outfitted with an optional cross band magnet and magnetic head pulley to pull metal from the top and bottom of material on the conveyor after it’s gone through the machine for cleaner finished material.

The HG4000 has a transport width of 2.5 meters (8.2 ft), height of 4 meters (13 ft), 5th wheel hitch trailer length of 9.7 meters (32 ft), and weight of 24,000 kilograms (52,910 lb), or a pintle hitch trailer length of 11.3 meters (37 ft) and weight of 25,000 kilograms (55,155 lb).
