Abstract
A tying machine may include a feeding mechanism configured to feed a tying string, a battery, and a voltage detection circuit configured to detect a voltage of the battery. The feeding mechanism may include a feeding motor to which power is supplied from the battery. The tying machine may be configured to set a duty ratio for driving the feeding motor when feeding the tying string, in accordance with the voltage of the battery detected by the voltage detection circuit.
