Agricultural implement having a tow bar device for towing the implement with a towing vehicle includes an implement part that trails the tow bar device mounted so as to be pivotable about a first pivot axis. The first pivot axis is parallel to a horizontal transverse axis of the implement. The trailing implement part and the tow bar device are coupled by means of at least one first actuator. The tow bar device, by means of the first actuator, is pivotable about the first pivot axis in such a manner that a tilt angle between the tow bar device and the trailing implement part is adjustable.

An exemplary self-locking actuator mechanism includes a floating plate and a linear actuator. The floating plate defines a first slot that includes a first central portion, a first jog extending laterally from a first end of the first central portion, and a second jog extending laterally from a second end of the first central portion. The linear actuator includes a shaft pivotably connected to the floating plate, and is operable to drive the shaft between a first shaft position and a second shaft position to thereby move the self-locking actuator mechanism between a first locking state and a second locking state.

A first assembly combinable to the heavy equipment and a second assembly pivotally attached to the first assembly for rotation about a first axis and configured for pivotal attachment to the vehicle for rotation about a second axis. A tow rod extending from the first assembly with a third axis extending therethrough and combinable to the heavy equipment and configured for rotation with respect to the heavy equipment about the third axis.

An offset towing apparatus for an implement supported by rear wheels rotating about an axis perpendicular to the operating travel direction. A tow arm connects between a vertical towing pivot axis at the towing vehicle and a vertical implement pivot axis at the implement hitch. A middle portion of the tow arm is pivotally attached about a vertical beam pivot to a beam on castor wheels. A strut attached to the implement pivot axis extends laterally and a bar is attached to the strut about a strut pivot axis and extends forward parallel to the tow arm to a front end attached to the beam about a bar pivot axis. The tow arm, the beam, the strut, and the bar form a parallel linkage between the beam pivot axis, the implement pivot axis, the strut pivot axis and the bar pivot axis allowing the implement to pivot to either side.

An articulating tongue arrangement includes a vehicle attachment section enabling attachment of the articulating tongue arrangement to a tow vehicle, an implement attachment section enabling attachment of the articulating tongue arrangement to an agricultural implement, and an articulating beam assembly located between the vehicle attachment section and the implement attachment section. The articulating beam assembly includes, in turn, a leading end portion movably coupled to the vehicle attachment section at a leading pivoting joint, a trailing end portion movably coupled to the implement attachment section at a trailing pivoting joint, and a beam assembly actuator coupled between the leading end portion and the trailing end portion of the articulating beam assembly. The beam assembly actuator is controllable to adjust an effective tow length of the articulating beam assembly, as measured along a straight line extending from the leading pivoting joint to the trailing pivoting joint.
