Abstract

An agricultural tillage implement includes a center frame section having a front frame member extending transverse to a travel direction, a rear frame member extending transverse to the travel direction, and a plurality of longitudinal frame members extending from and attached between the front frame member and the rear frame member. The plurality of longitudinal frame members include a pair of side frame members positioned at respective sides of the center frame section, and a pair of load distribution frame members. A plurality of tillage implements extend downwardly from the center frame section. A pull hitch is directly attached to the front frame member at two attachment locations and extends forward from the center frame section in the travel direction. Each attachment location is aligned with a respective load distribution frame member.

First claim

What is claimed is:

1. An agricultural tillage implement, comprising:
a center frame section including a front frame member extending transverse to a travel direction, a rear frame member extending transverse to the travel direction, and a plurality of longitudinal frame members extending from and attached between said front frame member and said rear frame member;
a plurality of tillage implements extending downwardly from said center frame section; and
a pull hitch directly attached to said front frame member and extending forward from said center frame section in the travel direction.

2. The agricultural implement of claim 1 , wherein said pull hitch is attached to said front frame member at two attachment locations, and wherein said plurality of longitudinal frame members include a pair of side frame members positioned at respective sides of said center frame section, and a pair of load distribution frame members each having one end which is aligned with a respective said attachment location.

3. The agricultural implement of claim 2 , wherein said pull hitch is pivotally attached to said front frame member at said two attachment locations.

4. The agricultural implement of claim 1 , further including a rear auxiliary tillage implement directly attached to said rear frame member.

5. The agricultural implement of claim 1 , further including a plurality of wing sections, including at least one left wing section pivotally coupled with a left side of said center frame section and at least one right wing section pivotally coupled with a right side of said center frame section.

6. The agricultural implement of claim 5 , wherein said center frame section includes a rear auxiliary tillage implement directly attached to said rear frame member, and each of said plurality of wing sections includes a rear auxiliary tillage implement.

7. The agricultural implement of claim 6 , wherein each said rear auxiliary tillage implement includes a multi-teeth drag and a rolling basket.

8. The agricultural implement of claim 6 , wherein each said rear auxiliary tillage implement includes a plurality of mounting brackets which are attached to said rear frame member.

9. The agricultural implement of claim 1 , wherein said agricultural tillage implement is a field cultivator.

10. An agricultural tillage implement, comprising:
a center frame section including a front frame member extending transverse to a travel direction, a rear frame member extending transverse to the travel direction, and a plurality of longitudinal frame members extending from and attached between said front frame member and said rear frame member, said plurality of longitudinal frame members including a pair of side frame members positioned at respective sides of said center frame section, and a pair of load distribution frame members;
a plurality of tillage implements extending downwardly from said center frame section; and
a pull hitch directly attached to said front frame member at two attachment locations and extending forward from said center frame section in the travel direction, each said attachment location being aligned with a respective said load distribution frame member.

11. The agricultural implement of claim 10 , wherein said center frame section includes a rear auxiliary tillage implement directly attached to said rear frame member.

12. The agricultural implement of claim 10 , wherein said pull hitch is pivotally attached to said front frame member at said two attachment locations.

13. The agricultural implement of claim 10 , further including a plurality of wing sections, including at least one left wing section pivotally coupled with a left side of said center frame section and at least one right wing section pivotally coupled with a right side of said center frame section.

14. The agricultural implement of claim 13 , wherein said center frame section includes a rear auxiliary tillage implement directly attached to said rear frame member, and each of said plurality of wing sections includes a rear auxiliary tillage implement.

15. The agricultural implement of claim 14 , wherein each said rear auxiliary tillage implement includes a multi-teeth drag and a rolling basket.

16. The agricultural implement of claim 14 , wherein each said rear auxiliary tillage implement includes a plurality of mounting brackets which are attached to said rear frame member.

17. The agricultural implement of claim 10 , wherein said agricultural tillage implement is a field cultivator.
