Summary:A three-point hitch for an agricultural tractor includes a lift arm, a lower link arm, and a lift spindle disposed between lift arm and lower link arm for transmitting a pivoting movement performed on the lift arm to the lower link arm. The lift spindle includes a first fastening section articulated on the lift arm and a second fastening section articulated on the lower link arm. An elongated hole is formed in the second fastening section along a longitudinal direction of the lift spindle, and a mounting pin extends through a fastening opening in the lower link arm and is mounted in the elongated hole. At least two locking regions are spaced apart from one another and formed along the elongated hole for receiving a shaped feature provided on the mounting pin. A movement of the lower link arm along the elongated hole is blocked when the shaped feature is received in one of the locking regions.
