This study was carried to develop the chip-harvester and to analysis the operation productivity and cost for effective collection and forwarding of forest biomass. Main target specification of chip-harvester is speed of 8km/h, maximum climbing capacity of 30° and maximum load capability of 2000 kg. Body structure is articulate type to reduce turning radius. Driving equipment is six-wheel drive, and a rear wheel is tandem bogie type to increase grip force. As a result of the driving test about developed chip-harvester, driving speed was 6.9 km/hr and 8.1 km/hr in ±10% slope with loaded and 7.3 km/hr and 7.9 km/hr in ±10% slope without load. As a result of the operation productivity and cost, operation productivity of grinding and forwarding was approximately 10 m3 per day, and operation cost was 393,126 won per day.
