A mobile wood chipper that is mounted to a small, comparatively light, motor vehicle and is contained within the vehicle during transit, for improved access to remote areas. The wood chipper has an input hopper that during operation is desirably located at a convenient height for a user. In the case of mounting in a station wagon or van, a slidable structure may be used to allow the wood chipper to be slid into an operational position with the wood chipper at least largely outside the vehicle, and a stowed position with the wood chipper at least largely inside the vehicle. In the case of mounting in a truck, a lift mechanism may be used to allow the wood chipper to be lowered into an operational position with the wood chipper at a convenient height for a user, and lifted up into a stowed position within the truck bed. A power generator is also included to supply power to the wood chipper.
