TBG 640 Horizontal Grinders

The TBG640 is a high-speed horizontal grinder designed for maximum production output and minimum operator downtime. It processes applications such as tree stumps, green waste, wood waste, logs, land clearing debris and C&D waste with a strong tolerance for high contamination. The TBG 640 horizontal grinder is designed for both primary grinding and regrinding duties and is operated by simple and intelligent control systems to ensure full operator control.

Available as a tracked or wheeled model, the grinder features a 41” high x 63” wide (1,041 mm x 1,600 mm) infeed opening and a 40” diameter x 189” length (1,016 mm x 4800 mm) feed roll. With convenient service access, the machine operator can conduct routine machine maintenance at a moment’s notice. Powered by either a 755 hp or 765 hp Caterpillar diesel engine, the TBG640’s advanced engine load management system maximizes production and fuel usage.
