The invention relates to a mechanized farming implement with a retractable transport wheel comprising a support (1) for attaching an articulated arm (2) intended to bear said transport wheel (4). According to the invention the attachment support (1) comprises at least one oblong slot known as a guide slot (64) designed to accept a guide pin (9) secured to said articulated arm (2) and able to move in said oblong guide slot (64) as said articulated arm (2) is moved from a transport position into a work position and vice versa. By virtue of the invention the articulated arm is easier to manoeuvre because the articulated arm is guided in its pivoting from the transport position into the work position and vice versa making retraction of the transport wheel easier and quicker than in known mechanized farming implements.
