装置。 A pair of left and right engagement recesses between the rear of the three-point linkage mechanism attached to the rear of the tractor and the front of the work equipment, and a pair of left and right engagement shafts that are removably engaged with these engagement recesses. an engaging portion having an engaging portion, which allows the engaging shaft portion to engage with the engaging recessed portion and prevents the engaging shaft portion engaged with the engaging recessed portion from disengaging. A pair of rotatable hooks are provided on the left and right at a first rotational position and a second rotational position that allows the engagement shaft to disengage from the engagement recess, and the rotation angle of the hooks is adjusted to In the coupling device for a work machine, the coupling device includes a spring that selectively biases the hook toward a first rotational position and a second rotational position in accordance with the rotational position, from the engagement recess of the engagement shaft. A biasing body is provided that biases the hook toward the first rotational position in response to the detachment of the hook, and the biasing force of the biasing body is set to be stronger than the biasing force of the spring. Work equipment coupling device.
