Abstract

A row cleaner assembly (5000) includes an upper subframe (5100A) mounted to an agricultural planter forward of the planter row unit and longitudinally aligned with the trench opening assembly. A lower subframe (5100C) rotatably supports first and second row cleaner wheels (5060-1, 5060-2). An intermediate subframe (5100B) 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 (5200-1, 5200-2) 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 (5300) is capable of applying a downforce and an optional lift force to the lower subframe. The row cleaner assembly includes a coulter (5555) supported by a rear strut subframe (5100D). The row cleaner assembly may include a depth selector to change the depth of penetration of the row cleaner wheels into the soil surface.

Dependent claims

A row cleaner assembly mounted to an agricultural planter, the agricultural planter having a row unit with a trench opening assembly configured to open a seed trench in a soil surface as the planter travels in a forward direction of travel, the row cleaner assembly comprising:

an upper subframe mounted to the planter forward of the row unit and longitudinally aligned with the trench opening assembly;
a lower subframe rotatably supporting first and second row cleaner wheels, the first and second row cleaner wheels oriented to diverge outwardly and rearwardly such that as the first and second row cleaner wheels rotate about their respective axes of rotation by engaging with the soil surface as the planter travels in the forward direction of travel;
an intermediate subframe pivotally connected at a forward end to the upper subframe and pivotally connected at a rearward end to the lower subframe;
a first linkage and a second linkage, each pivotally connected at a forward end to the upper subframe and each pivotally connected at a rearward end to the lower subframe;
an actuator system capable of applying a downforce to the lower subframe;
wherein the lower subframe includes a rear strut subframe and wherein a portion of the lower subframe is pivotally movable with respect to the rear strut subframe;
and
a coulter rotatable about a coulter axle supported by the rear strut subframe rearward of the first and second row cleaner wheels.

a lower subframe rotatably supporting first and second row cleaner wheels, the first and second row cleaner wheels oriented to diverge outwardly and rearwardly such that as the first and second row cleaner wheels rotate about their respective axes of rotation by engaging with the soil surface as the planter travels in the forward direction of travel, the rotating first and second row cleaner wheels direct crop residue laterally outwardly to provide a cleaner seed bed for the rearwardly aligned trench opening assembly;
a parallel arm linkage pivotally connect at its rearward end to the row unit and at its forward end to the lower subframe;
an actuator system capable of applying a downforce to the lower subframe;
wherein the lower subframe includes a rear strut subframe and wherein a portion of the lower subframe is pivotally movable with respect to the rear strut subframe;
and
a coulter rotatable about a coulter axle supported by the rear strut subframe rearward of the first and second row cleaner wheels.
