A cultivator includes at least one cultivator row unit, each of the at least one cultivator row unit having a support assembly for securing the cultivator row unit to a tool bar, a shank, an earth working tool operatively connected to the shank, and at least one assembly for providing discrete incremental adjustment for at least one of (a) an angle of the earth working tool, (b) a depth of the earth working tool, and (c) a gauge wheel depth.

A convertible box blade scraper apparatus includes a frame assembly including a first sidewall, a second sidewall, one or more shank support cross-members, a first blade support cross-member having a first scraper blade secured thereto, a second blade support cross-member extending between and secured to the first sidewall and the second sidewall, and having a second scraper blade and a leveling blade secured thereto, and a moldboard support cross-member, the moldboard support cross-member having a moldboard support longitudinal center axis. The apparatus further includes an elongated moldboard having an arc-shaped front surface that extends between a moldboard top edge and a moldboard bottom edge, the moldboard including one or more pivot arms rotatably coupled to the moldboard support cross-member to provide the moldboard with a pivot axis, wherein the pivot axis is coincident with the moldboard support longitudinal center axis, and further including a hitch assembly.

An agricultural row cleaner having: a frame; a first row cleaner wheel disposed on a first side of the frame; a second row cleaner wheel disposed on a second side of the frame; and a row cleaner diverter connected to the frame and disposed forward of the first row cleaner wheel and the second row cleaner wheel in a direction of travel and disposed between the first row cleaner wheel and the second row cleaner wheel.

An implement is disclosed for smoothing grounds that include at least a compact base having a top surface and a lesser compact footing on top of the base. The implement includes a frame having a front portion, a central portion, a rear portion, and a width. Wheels are mounted for rotation directly to the frame, and tools are carried by the frame for engagement with the ground. The tools include a specially shaped cleaving blade connected to the rear portion of the frame by a tool support, which securely connects the cleaving blade at predetermined heights. The blade has a front shaving edge and a rear compressing edge. The blade extends straight across the width of the frame so as to maximize the drag displaced on the frame during use of the blade. Arrangement of the wheels directly on the frame provides optimal stabilization of the frame during operation of the blade.

A row cleaner assembly includes an upper subframe mounted to an agricultural planter forward of the planter row unit and longitudinally aligned with the trench opening assembly. A lower subframe rotatably supports first and second row cleaner wheels. An intermediate subframe is pivotally connected at a forward end to the upper subframe and is pivotally connected at a rearward end to the lower subframe. A first and second linkages are pivotally connected at a forward end to the upper subframe and are pivotally connected at a rearward end to the lower subframe. An actuator system is capable of applying a downforce and an optional lift force to the lower subframe. The row cleaner assembly may include a gauge wheel supported by a rear strut subframe. The row cleaner assembly may include a depth selector to change the depth of penetration of the row cleaner wheels into the soil surface.

A cultivator includes at least one cultivator row unit, each of the at least one cultivator row unit having a support assembly for securing the cultivator row unit to a tool bar, a shank, an earth working tool operatively connected to the shank, and at least one assembly for providing discrete incremental adjustment for at least one of (a) an angle of the earth working tool, (b) a depth of the earth working tool, and (c) a gauge wheel depth.

A system for controlling an implement during a tillage operation may include a frame and a ground-engaging tool pivotally coupled to the frame and movable relative to the frame between a retracted position and an extended position. An actuator may be configured to bias the ground-engaging tool towards the extended position during the tillage operation. An adjustable valve may be configured to permit flow out of the actuator when a fluid pressure of the actuator exceeds a reset pressure such that the actuator allows the ground-engaging tool to pivot towards the retracted position. A controller may be configured to determine at least one of an actuator position or a load value indicative of a force applied by the ground-engaging tool against the soil during the tillage operation and adjust the reset pressure based on the at least one of the actuator position or the load value.
