During the cutting operation, if the shifter 149 is operated to slide the clutch 141 to the right in FIG. 3 and the claw portion 145 is disengaged from the claw portion 147 of the input gear 23,
The bundling work will stop and will not interfere with the cutting work.

As described above, this invention is based on a tying device in which a needle part for wrapping a tying string around a culm and a part of a knot for tying the tying string are provided facing each other via a culm passage. In a binding device equipped with a cutting device in which a cutting device for cutting the culm is integrally built into one side lower part of the culm passage, a transmission system for transmitting power to the scraping rotor of the cutting device includes: A clutch for connecting and disconnecting the power is provided, and the clutch is disconnected at a position where the scraping rod of the scraping rotor protrudes into the shell culm passage at approximately the same position as the T protrusion of the binding device, and the scraping rotor is turned off. Since this is a tying device equipped with a cutting device and a fixed position stopping device for stopping, the raking rod of the raking rotor is operated as a culm raking device during the cutting operation and also during the tying operation. By acting as a resistance rod at the tip of the culm, the direction in which the bundled bundles are released can be controlled.
