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