Abstract

A single arm row cleaner unit mountable to a grain drill opener arm includes a row cleaner arm and a mounting saddle. The mounting saddle is generally configured for attachment to a main arm of a furrow forming assembly. A row cleaner arm may be pivotally attached to the mounting saddle about a mandrel, and a row cleaner wheel may be pivotally mounted to the row cleaner arm. A biasing member may be positioned adjacent the mandrel to engage the row cleaner arm and a biasing member retainer, which may be affixed to the mounting saddle. A deflector may be positioned adjacent the row cleaner wheel and biased there against. A connector and lever arm may be used to communicate forces from a closing wheel arm to the row cleaner wheel for adequate clearance of the row cleaner wheel during transport of the grain drill.

3. The single arm row cleaner according to claim 2 wherein said deflector is further defined as comprising:

a. a deflector arm, wherein said deflector arm is affixed to said row cleaner arm;

b. a deflector blade, wherein said deflector blade is affixed to said deflector arm, and wherein said deflector blade is positioned adjacent said row cleaner wheel;

c. a pin, wherein said pin is positioned in a pin aperture formed in said row cleaner arm, and wherein a first end of said pin engages said deflector arm; and

d. a deflector biasing member, wherein said deflector biasing member is affixed to said row cleaner arm and engages a second end of said pin.

4. The single arm row cleaner according to claim 3 wherein said single arm row cleaner is further defined as being affixed to a main arm of said furrow forming assembly of said grain drill.

5. The single arm row cleaner according to claim 4 wherein said main body and said front portion of said saddle mount are further defined as being integrally formed.

6. The single arm row cleaner according to claim 5 further comprising a mounting saddle connector, wherein said mounting saddle connector functions to attach said mounting saddle to said furrow forming assembly.

7. The single arm row cleaner according to claim 6 wherein said mounting saddle connector is further defined as a plurality of u-bolts.

8. A single arm row cleaner comprising:

a. a mounting saddle configured to be affixed to a furrow forming assembly of a grain drill, said mounting saddle comprising;

i. a body;

ii. a front portion affixed to and angled with respect to said body; and

iii. a mandrel, wherein said mandrel is affixed to said front portion;

b. a row cleaner arm, wherein said row cleaner arm comprises;

i. a mounting aperture formed in a first end of said row cleaner arm, wherein said mounting aperture is positioned adjacent said mandrel, and wherein said row cleaner arm is pivotally mounted with respect to said mounting saddle about said mandrel;

ii. a wheel aperture formed in a second end of said row cleaner arm;

c. a row cleaner wheel, wherein said row cleaner wheel is pivotally mounted to said row cleaner arm about said wheel aperture;

d. a lever arm, wherein a first end of said lever arm is affixed to a closing wheel arm with a lever arm bracket; and

e. a connector, wherein a first end of said connector is affixed to a second end of said lever arm, and wherein a second end of said connector is affixed to said row cleaner arm.

9. The single arm row cleaner according to claim 8 further comprising a biasing member, wherein a first end of said biasing member is secured in a biasing member retainer affixed to said mounting saddle, and wherein a second end of said biasing member is secured to said row cleaner arm via a biasing member engager affixed to said row cleaner arm between said wheel aperture and said mounting aperture.

10. The single arm row cleaner according to claim 9 further comprising a deflector, wherein said deflector is mounted to said single arm row cleaner adjacent said row cleaner wheel.

11. The single arm row cleaner according to claim 10 wherein said deflector is further defined as comprising:

a. a deflector arm, wherein said deflector arm is affixed to said row cleaner arm;

b. a deflector blade, wherein said deflector blade is affixed to said deflector arm, and wherein said deflector blade is positioned adjacent said row cleaner wheel;

c. a pin, wherein said pin is positioned in a pin aperture formed in said row cleaner arm, and wherein a first end of said pin engages said deflector arm; and

d. a deflector biasing member, wherein said deflector biasing member is affixed to said row cleaner arm and engages a second end of said pin.

12. The single arm row cleaner according to claim 11 wherein said single arm row cleaner is further defined as being affixed to a main arm of said furrow forming assembly of said grain drill.

13. The single arm row cleaner according to claim 12 wherein said main body and said front portion of said saddle mount are further defined as being integrally formed.

14. The single arm row cleaner according to claim 13 further comprising a mounting saddle connector, wherein said mounting saddle connector functions to attach said mounting saddle to said furrow forming assembly.

15. The single arm row cleaner according to claim 14 wherein said mounting saddle connector is further defined as a plurality of u-bolts.
