A contract firm that specializes in clearing right-of-way for geophysical exploration and site development. They operate two Brown Bear FS4000 shredder units. The FS4000 units are equipped with GPS navigational units that direct the shredders via satellite to sub-meter accuracy. Production clearing rates vary depending upon population,wood density, terrain, operator, and soil conditions!

Reduces trees and shrubs up to 8 to 10 inches in diameter to mulch.

Reduce tire punctures, leaves mulch and smooth stumps - not sharp stobs.

Reduce landowner complaints

Reduce liability from flying debris.

Reduce overall operating costs.

Reduce extra safety personnel to stop traffic.

Redesigned head for better mulching efficiency.

Redesigned to discharge material down and under the machine with minimal unidirectional front discharge.

SAE standard parts, not metric.

Specifically designed swing out radiator and cooling systems, with onboard air compressor for easy maintenance.

Productivity of up to 3 acres per hour, depending on population, wood density, size of material and terrain.

Rotor is powered by a variable displacement hydrostatic pump which drives a fixed displacement motor. Final drive is through a toothed belt drive on the rotor end. Sealed rotor bearings.

The newly designed head incorporates cutter overlap and allows for quick changing of individual teeth.

Tip to tip cutting diameter of the rotor is 28 inches and the rotor is available in two different styles: swinging flair cutter and fixed tooth cutter.

The flail rotor is equipped with 54 sharpened, heat treated cutters, each independently, rotatively pin mounted.  The cutters are positioned in the drum by centrifugal force.  Should the cutter deflect, it is free to rotate 360 degrees around the pin mount to minimize damage.  Each cutter is overlapped on both sides by another cutter to deliver flat cut stumps.  One hundred percent of the cut width is cut by a cutter.

 

ITAM – Fort Drum, NY

Integrated Training Area Management (ITAM) operates the FS4000 with fixed tooth rotor in clearing troop and tank training and range areas for the Tenth Mountain Division at Fort Drum, New York. 

 

 

The fixed tooth rotor is equipped with 78 fixed carbide teeth.  Each tooth is overlapped on both sides by another tooth to deliver flat cut stumps.  One hundred percent of the cut width is cut by a tooth.
