Agricultural implement with boltless tines

1. An agricultural implement, comprising:

a chassis;

a hitch connected to said chassis; and

a harrow carried by said chassis, said harrow comprising:

a tine frame having at least one clamp tab formed as a lance tab in said tine frame; and

at least one tine clamped to said tine frame by said at least one clamp tab, said at least one tine including a clamped portion with a pair of opposite ends and a pair of vertically descending teeth, each of said vertically descending teeth being connected to a respective one of said opposite ends of said clamped portion.

2. The implement according to claim 1 , wherein said tine frame includes two clamp tabs clamping said clamped portion of said at least one tine to said tine frame.

3. The implement according to claim 2 , wherein said pair of opposite ends of said clamped portion define a clamping width therebetween which is equal to a maximum distance between said two clamp tabs.

4. The implement according to claim 1 , wherein said at least one clamp tab extends from a first surface of said tine frame and said tine frame includes a second surface angled with respect to said first surface, said at least one clamp tab clamping said clamped portion of said tine against said second surface.

5. The implement according to claim 4 , wherein said second surface includes a stop extending therefrom.

6. The implement according to claim 5 , wherein said clamped portion of said at least one tine defines a middle region which is equidistant from said opposite ends, said middle region of said clamped portion abutting against said stop.

7. The implement according to claim 5 , wherein said stop is formed as a lance tab in said second surface.

8. The implement according to claim 5 , wherein said clamped portion of said at least one tine defines a height, said at least one clamp tab and said stop defining a resting clearance therebetween which is less than said height of said clamped portion.

9. The implement according to claim 5 , wherein at least one of said at least one clamp tab and said stop comprises a reversibly deformable material.

10. The implement according to claim 1 , wherein said at least one clamp tab supports a bottom of said at least one tine.

11. The implement according to claim 1 , wherein said at least one clamp tab comprises a plurality of clamp tabs and said at least one tine comprises a plurality of tines, each of said plurality of tines being clamped to said tine frame by at least one of said clamp tabs.

12. The implement according to claim 11 , wherein said vertically descending teeth of said plurality of tines define an equal tooth spacing between adjacent teeth.

13. The implement according to claim 11 , wherein said plurality of clamp tabs are identical.

14. The implement according to claim 11 , wherein said plurality of tines are identical.

15. An agricultural implement, comprising:

a chassis;

a hitch connected to said chassis; and

a harrow carried by said chassis, said harrow comprising:

a tine frame having a first surface with at least one clamp tab and a second surface joined with said first surface and angled with respect to said first surface, said second surface comprising a stop extending therefrom; and

at least one tine clamped to said first surface and said second surface by said at least one clamp tab, said at least one tine including a clamped portion and at least one vertically descending tooth connected to said clamped portion.

16. The implement according to claim 15 , wherein at least one of said at least one clamp tab and said stop is formed as a lance tab.

17. The implement according to claim 15 , wherein at least one of said at least one clamp tab and said stop comprises a reversibly deformable material.
