An agricultural work vehicle according to an aspect of the present invention, which can adaptively adjust the velocity profile of the hitch according to the weight of the work machine, is characterized by comprising: a hitch on which an work machine is mounted； a weight calculation unit that calculates the weight of the work machine when the work machine is lifted following a first lift of the hitch； and a hitch controller that firstly lifts the hitch according to a reference velocity profile comprising a constant-velocity section (T) and, when calculation of the weight of the work machine is completed, generates an updated velocity profile comprising acceleration sections (a1, a2), constant-velocity sections (b1, b2), and deceleration sections (c1, c1) according to the weight of the work machine, and secondly lifts the hitch according to the updated velocity profile.
