In one aspect, a piston assembly for a fluid-driven actuator may include a piston defining a passage extending between first and second chambers of the actuator. The piston assembly may further include a valve having a valve head and a valve stem. The valve may be positioned within the passage and slidable between an open position and a closed position. The valve stem may extend outward from the passage into the second chamber when the valve is positioned in the closed position. Additionally, the piston assembly may include a spring compressed between the valve head and the piston. The spring may be configured to bias the valve to the closed position. The valve may be configured to move to the open position when a pressure in the second chamber exceeds a pressure threshold or when the valve stem contacts a cylinder of the fluid-driven actuator.

The agricultural row units feature soil finishing assemblies. This configuration of the finishing assembly provides a simple adjustment of the height of the finishing assembly to enhance usability and flexibility of the row unit. The improved adjustment mechanism enhances user control over the vertical distance between the finishing wheels/discs and the ground opening assembly. In an exemplary embodiment, soil finishing assembly is pivotally coupled to the row unit frame via a height adjustment assembly. The height adjustment assembly may feature a biasing member and other components to allow adjustment of one end of the pivotal coupling of the adjustment assembly within the row unit assembly.

A scraper system to remove and deflect debris and soil from a disc gang mounted on an agricultural implement is provided. The scraper system includes a mounting bracket member supported at a common axle in support of the disc gang. The mounting bracket member is aligned generally parallel to and located forward of the common axle, and is mounted at a forward end of an elongated carry member supported from the common axle. The elongated carry member is generally aligned perpendicular relative to the common axle. A scraper blade is supported by a scraper arm mounted at the mounting bracket member and is located above the common axle. The location of the scrapper blade and the scraper arm allows a deflector plate to be located at the rearward end of the carry member.

A carrier frame for a spring cushion truck hitch includes first side mounting plates and a transverse load-resisting tube connected between the mounting plates. The stiffener extends laterally beyond the first plate and includes second side plates which connect the frame of the hitch to the truck frame, so that the carrier frame can be removed from the hitch and the hitch re-used on a different truck having a different frame configuration.

Truck hitch mounting frame

A carrier frame for a spring cushion truck hitch includes side mounting brackets and a transverse load-resisting (torsion) bar connected between the mounting brackets. The mounting brackets connect the frame of the hitch to the truck frame, so that the carrier frame can be removed from the hitch and the hitch re-used on a different truck having a different frame configuration. The mounting brackets carry the hitch below the truck bumper which need not be removed or replaced.
