AI Technical Summary

Technical Problem

Existing row cleaners fail to provide optimal performance in terms of cleaning efficiency and soil preparation for seed trench opening.

Method used

A row cleaner assembly with an upper subframe, lower subframe, intermediate subframe, and actuator system that adjusts the downforce on row cleaner wheels and gauge wheels, allowing for dynamic adjustment of cleaning depth and force.

Benefits of technology

Enhances cleaning efficiency by dynamically adjusting downforce on the wheels, ensuring a cleaner seed bed for seed trench opening, thereby improving planting conditions.

Abstract

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.
