Furrow closing device
DCFirst Claim
1. In a planting assembly having a furrow forming mechanism, a seed dispensing mechanism for placing seeds in the furrow formed by said furrow forming mechanism, a structure for creating seed soil contact and conditioning the soil for seed germination and emergence comprising:
- support structure attached to said planting assembly;
a plurality of wheels having a plurality of teeth on the periphery thereof attached to said support structure rearwardly of said seed dispensing mechanism, and located to the sides of said furrow;
said teeth having sharpened faces to positively penetrate the soil as the wheels rotate;
said wheels attached to said support structure at an angle to the vertical; and
means connected between said support structure and said planting assembly for forcing said teeth of said wheels into the soil to condition the soil and establish positive seed soil contact.

Abstract
A seed furrow closing device for planting units including a plurality of closing wheels, each wheel having a plurality of sharpened teeth on the periphery. The closing wheels canted at an angle to the vertical and press toward the seeds in the furrow.
The teeth, controlled by down pressure mechanism, penetrate the soil to till compacted soil and firm loose soil to improve germination and emergence. The sharpened teeth interact with the soil to remove residue from the teeth as the teeth emerge. The penetration of the teeth helps break up clods and also stabilizes the rear of the planting unit.
A trailing press wheel over the furrow may provide intermittent compacting of the soil loosened by the closing wheels over the center of the furrow.
This loosening and compaction by the sharpened toothed wheels improves the germination and emergence of the seeds in the furrow.
