Knock-on sweep structure includes a wedge adapter having opposite sides with upper and lower surfaces that engage the wrap-around portion of the sweep stem. The upper and lower surfaces diverge at different rates from a narrow end to a wide end to improve sweep-adapter contact. In one embodiment, the upper and lower surfaces on each side are planar and define a compound angle. The differential rate of divergence assures early contact between the adapter and stem at a plurality of spaced locations for improved retention and more reliable sweep positioning.

Sweep retaining structure includes a spring wire retainer with a base supported in a groove on the underside of the wedge support which mates with a stem portion of the sweep. The wedge support is apertured, and a central curved portion of the retainer passes through the aperture and supports a sweep-contacting end above the surface of the wedge support. The end is biased toward a contact area on the sweep to engage the area and eliminate sweep loss problems by preventing the sweep from slipping downwardly from the mounted position. To remove the sweep, a tool is inserted through the slot to depress the retainer end, and the sweep is forced off the wedge support. A raised area on the sweep directs soil away from the retainer and contact area to reduce wear and eliminate depression of the end during operation. The underside of the raised area positions the wire end and provides bend-resisting support for the wire.

A sweep removal tool includes a pair of claws with angled surfaces conforming to the top edge of the sweep stem to locate the tool and help distribute sweep removal impact forces. A retainer depressor centered below the claws moves the retainer to a release position and slides between the angled surfaces during sweep removal. The depressor shape assures desired tine contact, even when the sweep is at an extreme position in the range of possible mounted positions, while preventing damaging contact as the depressor moves relative to the retainer during sweep removal. A curved surface extends between the claws and the depressor and facilitates free pivoting of the tine about the claw contact points to depress the retainer. The tool bottoms against the sweep when the depressor is moved to the release position to prevent retained damage from removal impact forces.

Ripper point structure includes a nose with a tapered top that initiates lift and fracture of compacted soil layers. The tapered top with an included angle of about 100 degrees just forward of the parting wear shin creates a parting stress which increases until the center portion of the soil profile is cut by a sharp leading edge of the shin. In a winged embodiment, gently sloping ripper point wings gradually enter the fracture plane left below the lifted compaction layer and initiate a second fracture of the soil profile. The wings are spaced rearwardly from the point so that the point and wear shin have enough time to lift, fracture, and part the soil profile in contact with the shank prior to any wing action.

Gang tube rail structure is attached to the lower front and rear corners of the implement gang tube to provide a lower clamp support. Two pivoting clamp jaws are attached to the clamp support and secured against the support by tightening a single clamp bolt extending between the lowermost portions of the jaws. A locator shoe is secured between the tube and the c-spring and includes a protrusion that projects into a hole in the c-spring. The ends of the locator shoe include short legs that wrap around the gang tube rail. The single clamp bolt provides a vertical clamp force that is approximately twice the tension generated in the bolt when the nut is tightened.

An agricultural implement including a coupling mechanism for coupling to a vehicle and a frame having a tool tube with a top, which is coupled to the coupling mechanism. The frame is adapted to be pulled by the vehicle. The agricultural implement includes a plurality of wheel assemblies coupled to the frame, which support the frame above a surface. The agricultural implement includes a tool tube bracket coupled to the tool tube. The agricultural implement includes a standard having a mounting portion and a tool-receiving portion. The mounting portion is coupled to the tool tube bracket for translational adjustment of a position of the standard relative to the tool tube. The agricultural implement includes a tool coupled to the tool-receiving portion of the standard.
