Welcome to Peterson, manufacturer of industry-leading Whole Tree Chippers and Debarkers, Horizontal Grinders, and Blower Truc ... ks and Trailers. Peterson Pacific Corp. has been an Oregon Corporation since 1981. The company began as Wilbur Peterson & Sons, a heavy construction company. Peterson expanded into manufacturing to develop equipment to suit their land clearing/construction needs. A portable chain flail Delimber-Debarker was designed first, the Model DD 4800. The Model DDC 5000, a portable Delimber-Debarker-Chipper, was developed next followed by the development of other portable equipment for the paper pulp industry. In 1990 Peterson developed its first wood waste recycling machine. Continuous development of wood grinders has led to the current line of horizontal feed wood grinders. These models have been very well received both in the U.S. and overseas, with production rates up to 150 tons per hour. The company has rapidly grown with the demands of the industry and in 1993 built their 60,000 sq. ft. manufacturing plant in Eugene, Oregon. In 2000 they expanded again, adding an additional 50,000 sq. ft. to the manufacturing facility. With the 2001 acquisition of manufacturing rights for the BloTech line of blower trucks, Peterson has extended its reach into the soil erosion and landscape markets, building trucks designed for distributing bark, mulch, compost, and soil amendments. In July of 2007, Peterson was purchased by Astec Industries, Inc., opening a new chapter in their corporate history. With Astec's on going investment in Peterson we have continued and accelerated our tradition of innovation by continuously developing new machines. read more
