Abstract
A representative system for preparing a field for planting includes: first disk blades, each exhibiting a first offset angle with respect to a tilling direction; second blades, each exhibiting a second offset angle with respect to the tilling direction; ripper shanks disposed behind the second disk blades; third disk blades disposed behind the ripper shanks, each exhibiting a third offset angle with respect to the tilling direction; fourth disk blades, each exhibiting a fourth offset angle with respect to the tilling direction; and a chopper reel disposed behind the fourth disk blades; wherein, with respect to magnitude, each of the first offset angle and the second offset angle is greater than each of the third offset angle and the fourth offset angle.
Claims18
A system for preparing a field for planting by breaking up soil compaction, the system comprising:
- a frame configured to be drawn over a field in a tilling direction;
- a first row of disk blades mounted to the frame and oriented transverse to the tilling direction, each of the disk blades of the first row of disk blades extending beneath the frame to engage soil of the field, and each of the disk blades of the first row of disk blades exhibiting a first offset angle with respect to the tilling direction;
- a second row of disk blades mounted to the frame and oriented transverse to the tilling direction, the second row of disk blades being disposed behind the first row of disk blades with respect to the tilling direction, each of the disk blades of the second row of disk blades extending beneath the frame to engage soil of the field, and each of the disk blades of the second row of disk blades exhibiting a second offset angle with respect to the tilling direction, the second offset angle mirroring the first offset angle with respect to the tilling direction;
- a row of ripper shanks mounted to the frame and oriented transverse to the tilling direction, the row of ripper shanks being disposed behind the second row of disk blades with respect to the tilling direction, each of the ripper shanks of the row of ripper shanks extending beneath the frame to engage soil of the field, each of the ripper shanks being configured to penetrate the soil and disrupt soil compaction;
- a third row of disk blades mounted to the frame and oriented transverse to the tilling direction, the third row of disk blades being disposed behind the row of ripper shanks with respect to the tilling direction, each of the disk blades of the third row of disk blades extending beneath the frame to engage soil of the field, and each of the disk blades of the third row of disk blades exhibiting a third offset angle with respect to the tilling direction;
- a fourth row of disk blades mounted to the frame and oriented transverse to the tilling direction, the fourth row of disk blades being disposed behind the third row of disk blades with respect to the tilling direction, each of the disk blades of the fourth row of disk blades extending beneath the frame to engage soil of the field, and each of the disk blades of the fourth row of disk blades exhibiting a fourth offset angle with respect to the tilling direction, the fourth offset angle mirroring the third offset angle with respect to the tilling direction;
- a chopper reel adjustably mounted to the frame and oriented transverse to the tilling direction, the chopper reel being disposed at a rearmost position behind the fourth row of disk blades with respect to the tilling direction, the chopper reel having chopper blades configured to rotate about a chopper blade rotational axis oriented transverse to the tilling direction to mix field residue located at a surface of the field and level the surface of the field while retaining decompaction of the soil;
- and
- a positioning assembly, mounted to the frame, having an actuator configured to apply downward pressure to adjust a position of the chopper reel relative to the frame to set a working depth of the chopper reel;
- wherein, with respect to magnitude, each of the first offset angle and the second offset angle is greater than each of the third offset angle and the fourth offset angle.
