A surface brake system for a detachable agricultural implement towed by a tow vehicle is provided. The detachable agricultural implement includes a frame connected by a telescoping tongue assembly at the tow vehicle. The frame and tongue assembly are movably supported by at least one wheel assembly having a circumferential tread surface. The brake system includes a pivot linkage pivotally connected at the frame of the detachable agricultural implement, and a horizontal aligned brake arm attached at the pivot linkage. The brake system further includes an actuator cylinder interconnected between the pivot linkage and the frame. Movement of the actuator cylinder causes the brake arm to engage a brake pad assembly against the outer circumferential tread surface of the wheel assembly so as to restrain movement of the wheel assembly and frame of the agricultural implement as the tow vehicle extends and retracts the telescoping tongue assembly.

A seed planting assembly is provided having a plurality of planting units supported by a tool bar, each of which being operable to form a seed trench in soil, plant seeds in the seed trench, and close the seed trench. Each planting assembly is supported by the tool bar via a mounting assembly that can be actuated by a vertical positioner to raise and lower individual planting units.

An in-line seed treating unit is provided for an air seeding implement to coat seeds carried by a flow of air through a product distribution line before being planted into the ground. The in-line seed treating unit includes a cylindrical housing having input and outlet ends located at opposing axial ends of the cylindrical housing to provide a generally linear overall flow path for the seed entrained air flow through the product distribution line. A baffle formed as a spiral flighting with an open center portion is disposed within the cylindrical housing to induce the air flow and entrained seeds in a spiral flow path along the housing axis and, thereby pushing the entrained seeds outwardly toward the inner wall of the housing. The seed treatment material is injected through an injection port located a distance less than one flighting pitch of the baffle from the beginning of the flighting so that the seed treatment material is dispersed within the air flow to coat the entrained seeds. Preferably, the in-line seed treating unit is formed as a modular component that can be inserted into any selected product distribution line on the air seeding implement.
