The tnple-shank npper for a excavator (back hoe) was developed as a reforestation machine to promote the regeneration of Fagus crenata BL. on steep slopes by natural seeding. The ripper is pinned to the tip of the arm and the bucket link of the excavator and rakes out the bamboo grass by its roots. The excavator naturally moves forward and backward, and it turns 360°, moreover, the arm with the ripper works as a third leg, therefore, it can cope with micro topography, and can do fine raking-out into a ring form or a curved-band form, and can do other work on the forest floor under its vertical crown projection. It can separate bamboo-grass roots from the bottom of a dense layer of bamboo-grass roots very well. It treats a swath 2.4〜2.6 m wide and covers 90 to 120 m/h on slopes of -13° to +10°. The average productivity in terracing is about 120 m/h with breadths of 2.5〜3.0 m on slopes of 10°, but this decreases to 60 m/h as slopes steepen to 35°. This is because the earth volume to be cut increases with increasing gradients of slopes.
