The deep tilling tines till the field to a depth of about 5 to 12 inches at row planting locations, loosening the soil for easy plant growth. This deep grooving action builds mounds of soil at both sides of the deep groove which are cleared by a second set of shallow tilling curved coulter tines followed by a third set of plurality of rows of shallow tilling toothed coulters that till the space between grooves to a depth of about 1 to 4 inches, providing a water reservoir space and clearing plant debris. A last row of shallow tilling ruffled coulters are provided to mix and incorporate into soil plant debris and plant stocks, anchoring tilled soil. | ||||||
| 75 | TILLAGE IMPLEMENT WITH ADJUSTABLE GANG ANGLE | US13964806 | 2013-08-12 | US20130327550A1 | 2013-12-12 | Rodney D. Hake; Michael J. Ohnsat; Hank A. Kummer |
| A tillage implement has gang assemblies of rotatable tillage tools that can be angle-adjusted from the seat of the towing tractor using hydraulic actuators. The tillage tools may comprise generally flat, wavy coulter blades or the like so that the machine may be set up for vertical tillage with the coulters aligned at a zero degree angle with the path of travel of the implement or for residue management operations with the coulters maintained at an oblique angle of up to ten degrees relative to the path of travel. A six degree angle is preferred for the residue management position. A master-slave hydraulic flow arrangement for the actuators assures simultaneous actuation, while mechanical synchronizing apparatus between the two front gang assemblies on the center frame section of the machine assures synchronized movement of those assemblies. Mechanical motion-transmitting mechanism transmits the hydraulically powered adjusting movement of the front gang assemblies to the rear gang assemblies. | ||||||

| A planting unit for depositing fertilizer and seed in a single pass, double shoot manner includes a rotating disc that cuts a furrow in a planting surface and a trailing seed boot, having a cutting edge, that cuts a vertically and horizontally offset trench in the furrow to form a seed bed in the planting surface. The disc has a mounting frame for mounting the disc to a linkage assembly that is, in turn, coupled to a toolbar mount. The seed boot is also attached to the mounting frame. This common attachment provides a relatively short and compact device without sacrificing fertilizer and seed stratification. | ||||||
