he Peterson model 5900 disk chipper is built to produce high quality paper chips when used with a Peterson model 4800 debarker or fuel chips as a stand alone fuel wood chipper. The same high quality chipping components have been used for many years in Peterson’s 5000G delimber/debarker/chipper.
The 5900 has a large feed throat capable of accepting up to a 23 inch (563mm) diameter tree or multiple smaller diameter stems. The 5900 is provided with a standard three knife disk, and is also available with an optional four knife disk. Peterson’s heavy-duty 66 inch (1676mm) diameter 4.75 inch (121mm) thick chipper disk has a replaceable 0.5 inch (13mm) thick wear plate. Chipping production rates from 60–100 tons (55–90 tonnes) can be achieved depending on chip size. The 5900 is designed with a minimum of complication for reliable low cost long term operation. The chipper disk is directly driven from a high-capacity dry-disk clutch and belts. The six-cylinder Caterpillar C18 engine is more economical and requires less maintenance than twelve-cylinder engines. A twelve channel radio remote control permits control of the 5900 by the loader operator. The machine can be also controlled from the control box on the chipper.
