An apparatus for preparing soil for the placement therein of at least one of seed and fertilizer. A frame is provided with there being first structure on the frame for penetrating the soil to create an opening for at least one of seed and fertilizer as the frame is advanced in a travel direction. A second structure is provided on the frame at least partially downstream of the first structure for at least one of a) stripping soil clods from the first structure and b) loosening soil downstream of the first structure.

1. An apparatus for preparing soil to be planted, said apparatus comprising:a frame having a front and rear; a coulter wheel mounted on the frame at an elevation at which said coulter wheel penetrates the soil as the frame is advanced in a travel direction over the soil; and at least one toothed wheel rotatably mounted on the frame and engaging the soil, a portion of said toothed wheel extending rearwardly of said coulter wheel with respect to said travel direction, and a forward portion of said toothed wheel overlapping a rear portion of said coulter wheel to strip soil clods from said coulter wheel. 2. The apparatus of claim 1 wherein said toothed wheel is angled to redistribute residue laterally from said opening created by said coulter wheel with the overlapping portion of said toothed wheel converging toward said coulter wheel so that the tips of the teeth are closest to said coulter wheel.3. The apparatus of claim 2 wherein said toothed wheels are both angled to redistribute residue laterally from said opening created by said coulter wheel with the overlapping portion of said toothed wheel converging toward said coulter wheel so that the tips of the teeth are closest to said coulter wheel.4. The apparatus of claim 1 which includes a pair of said toothed wheels.5. The apparatus of claim 1 wherein said coulter wheel has a central axis and said toothed wheel resides substantially entirely rearwardly of said central axis of the coulter wheel.6. The apparatus of claim 1 wherein said coulter wheel is one of a wave and a ripple construction.7. The apparatus of claim 1 in combination with a pair of discs mounted on the frame for continuously defining an open slot in the soil for receipt of at least one of seed and fertilizer as the frame advances in a travel direction.8. The apparatus of claim 7 in combination with a seed supply mounted on the frame for continuously delivering at least one of seed and fertilizer to soil and a pair of closing wheels mounted on the frame for continuously placing soil in said slot as the frame is advanced in a travel direction.9. A method of preparing soil to be planted, said method comprising:traversing the soil with a frame carrying a rotatable coulter wheel mounted at an elevation at which said coulter wheel penetrates the soil as the frame is advanced in a travel direction over the soil, and at least one toothed wheel rotatably mounted on the frame, a portion of said toothed wheel extending rearwardly of said coulter wheel with respect to said travel direction, and a forward portion of said toothed wheel overlapping a rear portion of said coulter wheel to strip soil clods from said coulter wheel, said toothed wheel being mounted at an elevation at which said toothed wheel engages the soil to redistribute residue on the soil. 10. The method of claim 9 wherein said toothed wheel is angled to redistribute residue laterally from said opening created by said coulter wheel with the overlapping portion of said toothed wheel converging toward said coulter wheel so that the tips of the teeth are closest to said coulter wheel.11. The method of claim 9 which includes a pair of said toothed wheels.12. The method of claim 11 wherein said toothed wheels are both angled to redistribute residue laterally from said opening created by said coulter wheel with the overlapping portion of said toothed wheel converging toward said coulter wheel so that the tips of the teeth are closest to said coulter wheel.13. The method of claim 9 wherein said coulter wheel has a central axis and said toothed resides substantially entirely rearwardly of said central axis of the coulter wheel.14. The method of claim 9 wherein said coulter wheel is one of a wave and a ripple construction.15. The method of claim 9 which includes continuously forming an open slot in the soil behind the toothed wheel for receipt of at least one of seed and fertilizer as the frame advances in a travel direction.16. The method of claim 15 which includes continuously delivering at least one of seed and fertilizer to soil and a pair of closing wheels mounted on the frame for continuously placing soil in said slot as the frame is advanced in a travel direction.17. An apparatus for preparing soil to be planted, said apparatus comprising:a frame having a front and rear; a coulter wheel mounted on the frame at an elevation at which said coulter wheel penetrates the soil as the frame is advanced in a travel direction over the soil; and at least one toothed wheel rotatably mounted on the frame and engaging the soil, said toothed wheel overlapping a rear portion of said coulter wheel to strip soil clods from said coulter wheel and tracing a path in rotation bounded by a plane that intersects said coulter wheel. 18. A method of preparing soil to be planted, said method comprising:traversing the soil with a frame carrying a rotatable coulter wheel mounted at an elevation at which said coulter wheel penetrates the soil as the frame is advanced in a travel direction over the soil, and at least one toothed wheel rotatably mounted on the frame and overlapping a rear portion of said coulter wheel to strip soil clods from said coulter wheel and tracing a path in rotation bounded by a plane that intersects said coulter wheel, said toothed wheel being mounted at an elevation at which said toothed wheel engages the soil to redistribute residue on the soil. 19. An apparatus for preparing soil to be planted, said apparatus comprisinga frame having a first portion adapted to mount a rotatable coulter wheel at an elevation at which said coulter wheel penetrates the soil as the frame is advanced in a travel direction over the soil, and a second portion adapted to mount at least one rotatable toothed wheel in a position at which said toothed wheel engages the soil as the frame is advanced in a travel direction over the soil, with a portion of said toothed wheel extending rearwardly of said coulter wheel with respect to said travel direction, and a forward portion of said toothed wheel overlapping a rear portion of said coulter wheel to strip soil clods from said coulter wheel, a coulter wheel adapted to be mounted on said first portion of said frame, and at least one toothed wheel adapted to be mounted on said second portion of said frame. 20. A method of preparing soil to be planted, said method comprisingproviding a frame having a first portion adapted to mount a rotatable coulter wheel at an elevation at which said coulter wheel penetrates the soil as the frame is advanced in a travel direction over the soil, and a second portion adapted to mount at least one rotatable toothed wheel in a position at which said toothed wheel engages the soil as the frame is advanced in a travel direction over the soil, with a portion of said toothed wheel extending rearwardly of said coulter wheel with respect to said travel direction, and a forward portion of said toothed wheel overlapping a rear portion of said coulter wheel to strip soil clods from said coulter wheel, providing a coulter wheel adapted to be mounted on said first portion of said frame, and providing at least one toothed wheel adapted to be mounted on said second portion of said frame.
