An agricultural tillage implement for use in a field. The agricultural tillage implement including a frame section and a plurality of wing sections. The frame section has a pull hitch extending in a travel direction. Each of the plurality of wing sections are coupled to the frame section and/or a wing section. The wing sections each have an articulated portion pivotal about an axis substantially perpendicular to the travel direction.

The present document discloses an agricultural implement comprising a first frame section (10), a portion (11a, 11b, 12a, 12b), which is moveable relative to the first frame section, and an actuator (15a, 15b, 16a, 16b, 215) for controlling a relative movement between the first frame section (10) and the portion (11a, 11b, 12a, 12b). The agricultural implement has a first sensor (20, 220), arranged to provide a first value corresponding to the angle of the first frame section relative to a predetermined reference plane or a predetermined reference direction, and a second sensor (21, 22), arranged to provide a second value corresponding to the angle of the portion relative to the predetermined reference plane or the predetermined reference direction. Said reference plane or reference direction is defined in relation to a direction of gravity.

An agricultural tillage implement includes a main section including a hitch extending in a travel direction, a plurality of foldable wing sections coupled with the main section, a plurality of ground engaging tilling elements, a plurality of wheel assemblies and a control system. The tilling elements are coupled to the main section and wing sections. Each of the wheel assemblies include an actuator. The wheel assemblies include a first plurality of wheel assemblies associated with the main section and a second plurality of wheel assemblies associated with the plurality of wing sections. The actuators of the first plurality of wheel assemblies being independent of the actuators of the second plurality of wheel assemblies. The control system is configured to actuate the actuators to control a depth of tilling elements in each of the sections when the implement is in a field mode.

An agricultural tillage implement includes a main section including a hitch extending in a travel direction, a plurality of foldable wing sections coupled with the main section, a plurality of ground engaging tilling elements, a plurality of wheel assemblies and a control system. The tilling elements are coupled to the main section and wing sections. Each of the wheel assemblies include an actuator. The wheel assemblies include a first plurality of wheel assemblies associated with the main section and a second plurality of wheel assemblies associated with the plurality of wing sections. The actuators of the first plurality of wheel assemblies being independent of the actuators of the second plurality of wheel assemblies. The control system is configured to actuate the actuators to effect a profile minimizing operation of the foldable wing sections when the implement is being transitioned into a transport mode.

An agricultural tillage implement includes a main section including a hitch extending in a travel direction, a plurality of foldable wing sections coupled with the main section, at least one auxiliary implement assembly coupled to each of the wing sections and a control system. Each auxiliary implement assembly includes at least one support member, at least one pivotal arm pivotally coupled to the support member, at least one actuator coupled to both the support member and the pivotal arm and a ground contacting implement coupled to the pivotal arm. The control system is configured to actuate the actuators to control a position of each ground contacting implement in each of the sections when the agricultural implement is transitioning to a transport mode.

A tillage implement has a main frame, a hinged wing and a plurality of gangs each having tools along its length. The plurality of gangs includes a main frame gang mounted to the main frame and inner and outer wing gangs mounted to the wing. The inner and outer wing gangs have inner ends that are forward or rearward with respect to the direction of travel of outer ends, and the lengths of the inner and outer wing gangs are offset from each other in the direction of travel.

A drawbar for finishing attachments is arranged to attach to a fore-aft frame member of a tillage implement. The drawbar has a saddle with spaced apart side walls defining a channel configured to receive the frame member. When the frame member is received in the channel, the side walls of the saddle overlap side walls of the frame member and extend in the fore-aft direction rearward of an end of the frame member. The side walls of the saddle and the frame member have mounting openings that align along a lateral direction transverse to the fore-aft direction.

A triple-fold agricultural implement includes a center frame section, and a plurality of wing sections positioned on opposite lateral sides of the center frame section. The plurality of wing sections include an inner wing section, a middle wing section and an outer wing section. Each outer wing section may be folded approximately 180 laterally inward and over a respective middle wing section. Each middle wing section may be folded approximately 180 laterally inward and over a respective inner wing section. Each inner wing section may be folded approximately 90 laterally inward and over the center frame section, whereby each of the plurality of wing sections when in a folded state are in a transport position lying above the center frame section.

A suspension mechanism for a rotary rake implement incorporates elastomeric shock absorbing members in the corners of a tubular member situated in between the corners of a square rod formed as part of the wheel assembly and received within the tubular member such that the corners of the square rod assert a pre-load spring force on the tubular member when the implement is in an extended operating configuration. The movement of the implement into a folded transport configuration with the weight of the implement supported on the transport wheel assemblies causes a deflection of the square rod that compresses the elastomeric shock absorbing members within the corners of the tubular member to provide maximum suspension for the implement when in transport, while providing minimum suspension when the implement is in operation. An end cap on the square rod engages a stop formed on the tubular member to control rotation.

A folding agricultural implement including a plurality of tilling sections and a hinge system. The tilling sections include first and second tilling sections, with the second tilling section being pivotally coupled to the first tilling section about a first pivot axis. The hinge is system coupled to both tilling sections. The hinge system includes a link, an actuator, at least one wheel and a ramp system. The link is pivotally coupled to the first tilling section about a second pivot axis. The actuator has a pivoting connection on each end with one pivoting connection being coupled to the second tilling section and the other pivoting connection is coupled to the link, with the actuator having a range of travel. The wheel is rotationally coupled to the link. The ramp system is configured for the wheel to traverse thereover for a portion of the range of travel of the actuator.
