To provide a reaping machine wherein in reaping of branches and leaves of a tree and weed, reaping is carried out finely chopping the branches and leaves and the weed and the reaped materials can be automatically accumulated in an accumulating tank evacuated by using a vacuum route.

In a hood of the reaping machine 1, reaping teeth for reaping the branches, leaves and the weed are fitted to two pieces of rotors arranged parallel to an axis which are rotated at a high speed in mutually opposite directions. The drooped branches, leaves and the weed also are reaped being finely cut since rotary orbits of the reaping teeth pass alternately a part in the rotary orbit of mutually mate teeth. Since the reaped materials are finely cut, the reaped materials can be automatically accumulated by connecting the reaping machine 1 to the vacuumed accumulating tank 3 by using the vacuum route 2. The reaping operation can be carried out by a remote operation 23 by attaching the reaping machine 1 to a tip of an arm 4b capable of moving in three dimensional directions by making such the condition.
