A feed conveyor for conveying wood to be crushed is installed on one side of the body frame in the longitudinal direction thereof and includes a drive wheel, a driven wheel, and a running member looped between the drive wheel and the driven wheel. A bottom-equipped hopper having side walls on both sides of the feed conveyor in the transverse direction thereof, and a bottom wall disposed under the feed conveyor has a guide member disposed in continuation with the bottom wall of the hopper at a position near the drive wheel of the feed conveyor to prevent wood pieces from accumulating near the drive wheel. This arrangement prevents the wood pieces from being dropped onto the ground during the crushing work.
