It can produce paper quality chips when used with a Peterson 6800 Debarker, or fuel chips as a standalone fuel wood chipper.
The 6910 is powered by a Caterpillar C27 Tier III engine that produces 1,050 hp (772 kW), or an optional C32, 1,125 hp (839 kW) engine. The 6910 comes with a five pocket, 86 in (218 cm) diameter chipper disc with traditional babbitted knife systems, or Key Knife™ systems, with several optional sheave sizes to produce the chip size required. The chipper disc is directly driven from a hydraulic clutch and belts. Peterson claims chipping production rates of up to 200 US tons (181 tonnes) per hour can be achieved, depending on the chip size required. The 6910 has a large feed throat can accept up to 27 in (69 cm) diameter trees or multiple smaller stems. The 6910’s parallel wall feed throat stabilizes logs. Direct drive feed rollers results in no chain and sprocket wear, nor is there a need for adjustments. In order to control the stem better during chipping for high quality chips, Peterson has minimised the distance from the feed roller to the disc. A primary and secondary anvil provides easily serviceable cutting surfaces for good chip quality.
The chipper housing has a quick release hood clamp, bolt in disc wear liners, and an over-sized hood which easily opens out of the way for superior disc access for knife changes. Servicing the 6910 is accessible from the convenient platforms around the engine and chipper. Source: http://www.petersoncorp.com/products/6910-disc-chipper/
