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.

A coupler includes a collar defining a member receiving passage. First and second lobes extend outwardly from the collar. The first lobe includes a lobe ramp surface, a cylindrical projection extending from the first lobe and radially surrounding the lobe ramp surface, and a gear extending from the cylindrical portion. A passage is defined in the first and second lobes and has a first axis. A lever arm is rotatable about the first axis. The lever arm includes a lever ramp surface. A pawl arm is movably connected to the lever arm. The pawl arm includes a portion biased into engagement with the gear teeth. A fastener extends through the passage and couples the lever arm to the first lobe so the lever ramp surface cams with the lobe ramp surface. Rotation of the lever arm in a first direction brings the first and second lobes toward each other.

A road transport system of a header of a harvesting machine includes two pairs of wheels and two wheel frames. Each wheel frame is connected to a pair of wheels. The two wheel frames are rotatable between a field operation position and a road transport position. A header of a harvesting machine includes two pairs of wheels and two wheel frames. Each wheel frame is connected to a pair of wheels. The two wheel frames are rotatable between a field operation position and a road transport position. A method of converting a header of a harvesting machine from a field operation mode to a road transport mode includes: releasing wheel frames of the header from the header; rotating the wheel frames from a field operation position to a road transport position; and enabling kingpin steering connections between at least one of the wheel frames and a pair of wheels.

A second data processor determines candidate passes of the second vehicle in alignment with the defined plant rows to provide area coverage of the work area or field within the defined boundary based on an implement width or swath of the second vehicle and row spacing of the second vehicle, wherein the one or more candidate passes are associated with the defined plant rows consistent with a planned guidance path. From the present position and heading of the second vehicle, a user interface or display displays the determined candidate passes to minimize overlap of adjacent candidate passes of the second vehicle and to minimize any yield loss associated with unharvested/untreated passes or zones within the work area or field. The user interface or display supports selection of one of the displayed or presented candidate passes as the planned guidance path of the second vehicle consistent with the provision of area coverage of the work area or field.

A stand or fixture for supporting a mower cutting unit having a base frame with side members interconnected with at least 2 cross members. A cradle supports stable engagement with a roller of a mower cutting unit, and is secured to and extends upward from and between the side members. The cradle is parallel to the cross members, and positioned above the side members, supported on and secured to riser members. Each of the riser members is secured to a side member. A support member is adjustably secured at a desired location between cross members, and has a top portion extending upwardly away from the base frame, and above the cradle. The support member includes aligned openings above the cradle for receiving and securing a support pin supporting a support chain for engaging and suspending the mower cutting unit supported within the cradle, for accessing components of the mower cutting unit for service.

An agricultural system includes an arm that supports a cutter bar assembly and is coupled to a fluid-filled biasing member such that the fluid-filled biasing member imparts a torque onto the arm. The agricultural system further includes an actuator and a controller. The actuator is coupled to the fluid-filled biasing member and is configured to move the fluid-filled biasing member relative to the actuator to change the torque imparted by the fluid-filled biasing member onto the arm. The controller is configured to determine a target position of the arm associated with a leveled configuration of the cutter bar assembly, receive an input to set the cutter bar assembly in the leveled configuration, and output a signal to instruct the actuator to set the fluid-filled biasing member relative to the actuator based on the target position upon receiving the input to set the cutter bar assembly in the leveled configuration.

An agricultural system includes a frame, a cutter bar assembly configured to move relative to the frame during an operation of the agricultural system, a reel assembly configured to guide crops to the cutter bar assembly during the operation of the agricultural system, and a controller. The controller is configured to receive feedback indicative of a profile of the cutter bar assembly, set a position boundary of the reel assembly based on the feedback, and block movement of the reel assembly to a position beyond the position boundary of the reel assembly.
