PROBLEM TO BE SOLVED: To provide a monoaxial rotation tiller which is improved to enable simple earthing works and furrowing works even in a lightweight small crop management machine and in whose reverse rotation tilling tine shaft portion a plurality of rows of tine seats are arranged to use outward hatched tines on the reverse rotation tilling tine shaft, thereby simplifying the roles of the earthing works and the furrowing works.;SOLUTION: In the crop management machine manufactured by disposing a tilling device R in the front portion, disposing wheels 18 behind the tilling device R, and disposing an operation handle 9 behind the wheels 18, the forward/reverse rotation tiller whose reverse rotation tilling tines 5 on the reverse rotation tilling tine shaft 3 are rotated in the clock-wise direction and whose forward rotation tilling tines 30 on the forward rotation tilling tine shaft 1 are rotated in the counter clock-wise direction is characterized by detaching the forward rotation tilling tines 30 on the forward rotation tilling tine shaft 1 to use the outward reverse rotation tilling tines on the reverse rotation tilling shaft 3, on the earthing works, thereby enabling the earthing or furrowing works.;COPYRIGHT: (C)2006,JPO&NCIPI
