An agricultural apparatus (2) that is configured to travel over the ground includes a pick-up device (22) for picking up an agricultural bale (24) from the ground. The pick-up device (22) includes a sensing system (60, 62) that is configured to sense the position and/or size of an object on the ground as the agricultural apparatus travels towards the object, a pick-up mechanism (26) that is engageable with opposite sides of the object and operable to lift the object, and a control unit (64) that is configured to determine the position of the pick-up mechanism (26) relative to the object (24) based on signals received from the sensing system (60, 62) prior to picking-up the object, and to operate the pick-up mechanism (26) when the pick-up mechanism is positioned correctly relative to the object. |
