An agricultural tillage implement with a hydraulic system having a left wing hydraulic subsystem with an outer left wing hydraulic circuit supplying hydraulic pressure and flow to an actuator for actuating an actuator of an outer left wing folding implement section, and a right wing hydraulic subsystem having an outer right wing hydraulic circuit for actuating the actuator of an outer right wing implement section; the hydraulic system additionally having a hydraulic flow divider dividing hydraulic flow and pressure between the outer left wing hydraulic circuit and the outer right wing hydraulic circuit, the hydraulic flow divider being configured to coordinate the motion of the outer left wing section and the outer right wing section.

An agricultural implement having ground engaging components and inboard and outboard frame members are safely unfolded by using a radar or laser sensor to detect the presence of an obstacle in the unfolded position. A warning signal or disabling the unfolding process occurs when an obstacle is detected.

An agricultural implement comprising a first frame section, a portion which is moveable relative to the first frame section, and an actuator for controlling a relative movement between the first frame section and the portion. The agricultural implement has a first sensor 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 arranged to provide a second value corresponding to the angle of the portion relative to the predetermined reference plane or the predetermined reference direction. The reference plane or reference direction is defined in relation to a direction of gravity.

In one aspect, a method for reducing an overall transport profile of a multi-section tillage implement is disclosed. The tillage implement may include a frame including a center frame section and at least one wing frame section. The tillage implement may include a plurality of ground-engaging tools pivotally mounted to the frame. The method may include pivoting each of the plurality of ground-engaging tools away from the ground surface from a ground-engaging position to a retracted position. The frame may be disposed at an initial height relative to the ground surface before pivoting. After pivoting, the frame may be lowered to a transport height relative to the ground surface. At least one wing frame section may be folded relative to the center frame section from an operating position to a transport position to reduce a width of the tillage implement in the widthwise direction.

A method for controlling the actuation of wing sections of an agricultural implement may include regulating a supply of hydraulic fluid to a wing actuator coupled to a wing section to pivot the wing section relative to a center frame section of the implement from a transport position towards a work position. The method may also include monitoring a wheel load associated with at least one wheel of the wing section as the wing section is being moved towards the work position and detecting when the wheel(s) of the wing section contacts the ground based at least in part on the monitored wheel load. In addition, the method may include adjusting one or more flow parameters of the supply of hydraulic fluid to the wing actuator to reduce an actuation rate at which the wing section is being pivoted after detecting that wheel(s) has contacted the ground.

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.

An agricultural tool bar is provided with outer wings foldable between a lowered use or field position and a raised transport position. A primary pair of hydraulic cylinders fold and unfold the wings, while a secondary pair of hydraulic cylinders initially incline the wings from the horizontal use position before folding to the transport position. The secondary set of cylinders allow the tool bar to be used for narrow row planting without interference from seed boxes mounted on the toolbar center frame and the wings. The primary cylinders extend to push the wings to the transport position and retract to pull the wings to the use position.

An implement for clipping weeds in a field, where the weeds are standing taller than the crop. The implement comprises a plurality of rotatable blades on a frame, with variable height adjustment means to elevate the frame and position the blades above the crop but at a level sufficient to clip the upper portions of the weeds, The blades are powered by PTO-driven shaft segments, the segments connected by U-joints, wherein the implement further comprises alignment means for aligning the U-joints so that the frame can be folded for transport without damaging the shafts or U-joints.
