Abstract
A striptill row unit includes a trash cleaner assembly, a coulter assembly, a knife assembly, a berm disc assembly, and a firming wheel assembly. The berm disc and firming wheel assemblies are independently movable between a raised transport position and a lowered field position. The knife assembly includes downwardly angled wings with leading edges extending substantially perpendicular to the line of travel of the row unit. Up/downforce systems are provided for various assemblies, with an independent actuator for each system. The berm discs are adjustable vertically, laterally, and angularly.
