Abstract

An agricultural tillage implement has a vertical tillage section and an aerating section behind the vertical tillage section, each extending substantially perpendicular to the pull direction of the implement. Individual vertical tillage elements, such as disc blades, can be indexed with individual rotary tine assemblies of the aerator section so that discrete holes formed by the aerator section are positioned between substantially continuous slits formed by the vertical tillage section. Rolling baskets can be provided behind the aerator section for further soil conditioning.

First claim

What is claimed is:

1. An agricultural tillage implement, comprising:
a main frame including a pull hitch extending in a travel direction;
a vertical tillage assembly including a plurality of disc blades carried by the main frame and extending generally laterally with respect to the travel direction;
an aerating assembly including a plurality of rotary tine assemblies operably carried by the main frame behind the vertical tillage assembly, the plurality of rotary tine assemblies extending generally laterally with respect to the travel direction, wherein each rotary tine assembly of the plurality of rotary tine assemblies includes a plurality of individual tines, each individual tine of each rotary tine assembly connected to a hub, each hub of each rotary tine assembly connected via an arm which connects to and extends a distance from a rotary tine assemblies frame carried by the main frame, the plurality of individual tines are positioned about each hub such that each individual tine creates a separate discrete hole for aeration in the ground being tilled, such that the plurality of individual tines positioned about each hub does not form a continuous slit through the ground being tilled, wherein each individual tine on each hub is positioned in its entirety at a 90 degree angle relative to each tine on either side thereof, wherein each individual tine is formed as a knife with one edge of the tine having a slope at the free end toward an opposing edge of the tine, creating a knife point at a free end of each individual tine, and wherein opposing rotary tines positioned about each hub of each rotary tine assembly are in a longitudinal alignment relative to each other, the longitudinal alignment extending through each connected end and each free end of each opposing rotary tine; and
a soil conditioning assembly including a plurality of rolling basket assemblies positioned behind the plurality of rotary tine assemblies to smooth the oil.

2. The agricultural tillage implement of claim 1 , wherein the plurality of disc blades are arranged in a disc blade left row and a disc blade right row symmetric about an implement centerline.

3. The agricultural tillage implement of claim 1 , wherein the plurality of rotary tine assemblies are arranged in a rotary tine assembly left row and a rotary tine assembly right row symmetric about a centerline of the implement.

4. The agricultural tillage implement of claim 3 , wherein individual disc blades of the plurality of disc blades form a substantially continuous slit through ground being tilled.

5. The agricultural tillage implement of claim 4 , wherein the plurality of disc blades and the plurality of rotary tine assemblies are indexed so that the plurality of rotary tine assemblies operate in ground between the paths of the plurality of disc blades.

6. The agricultural tillage implement of claim 1 , wherein the plurality of disc blades and the plurality of rotary tine assemblies are substantially perpendicular to the travel direction.

7. The agricultural tillage implement of claim 6 , wherein the plurality of disc blades and the plurality of rotary tine assemblies are substantially parallel to one another.

8. The agricultural tillage implement of claim 1 , wherein the plurality of disc blades and the plurality of rotary tine assemblies are provided in left rows and right rows symmetric about a centerline of the implement.
