Striptill row unit
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.
1 . An agricultural striptill row unit for tilling soil, comprising:
a trash cleaner at a forward end of the row unit;
a coulter assembly behind the trash cleaner;
a knife behind the coulter assembly for applying fertilizer;
berm discs behind the knife; and
a firming wheel behind the berm discs at a rearward end of the row unit;
the berm discs and firming wheel being foldable between a field position and a transport position;
the firming wheel being foldable independently from folding of the berm discs;
a first actuator to fold the berm discs, and a second actuator to fold the firming wheel; and
a third actuator to control penetration of the coulter assembly and the knife into the soil.
2 . The agricultural striptill row unit of claim 1 further comprising a fourth actuator to control up and down force of the striptill row unit.
3 . The agricultural striptill row unit of claim 1 wherein the berm discs are adjustable vertically, laterally, and angularly.
4 . The agricultural striptill row unit of claim 1 further comprising a gauge wheel associated with the coulter assembly to control depth of the coulter assembly in the soil.
5 . The agricultural striptill row unit of claim 1 further comprising independent up/downforce systems for each of the coulter assembly, berm discs, and firming wheel.
6 . The agricultural striptill row unit of claim 1 wherein the knife has opposing wings with leading edges extending substantially perpendicular to a line of travel for the striptill row unit.
