Is configured to perform a reverse rotation operation of the motor M that drives the motor M.

It is preferable that the motor M is rotated in a reverse direction by a timer for a predetermined period of time and then stopped. In addition, after the excessively large rush seedlings G are artificially divided, the pretreatment device is restarted to perform reprocessing. As shown in FIGS. 1, 3, and 4, the cutting section 2 grips and transports the rush seedlings G near the end of the substantially horizontal portion of each of the endless rotating belts 5a and 5b. Disc-shaped cutters 6 and 7 are provided for cutting and aligning the tip of the root portion with a predetermined length. Each of the cutters 6, 7 is composed of two upper and lower sheets, and the cut chips are allowed to fall downward from the left and right sides.

The lower disk-shaped cutter 7 that cuts the root of the rush seedling G has its blade portion inserted into the container 60 at a lower position. A solvent is stored in the container 60, and the cutter 7 rotates, so that the blades around the entire circumference are immersed in the solvent. As this solvent, if an insecticide, a herbicide, a germination promoter, etc. are mixed in addition to water, the cutter 7
Can be supplied to the roots of the rush seedlings G. In addition, this solvent can wash off soil adhering to the blade portion of the cutter 7, and can prolong the life of the cutting effect.
