Abstract
A tillage tool achieves stability at higher speed ranges by providing stabilization with additional damping through damping elements on the front support wheels and on the constant level linkage and on the rear tool. The tillage tool maintains maximally one longitudinally positioned unsuspended load path to the ground provided by unsuspended depth gauging wheels longitudinally positioned parallel to a front to rear rocking axis to allow for constant settings throughout the depth, speed, and field condition ranges.
Claims12
A towable disc tillage tool, comprising:
- a plurality of discs for mixing at a predetermined soil depth;
- and
- a stability control system including a combination of mechanical and hydraulic dynamic force control through damping of the leveling linkage, front support wheels, rear tools and the position of the depth gauging wheels.
A wing depth gauging wheel for a towable disc system, comprising:
- a tire mounted to a hub;
- a movable arm connected to the hub
- a length adjustable hydraulic actuator;
- and
- a single screw incorporated in between an end of a rod and a clevis of the hydraulic actuator for adjustment of a length of the hydraulic actuator.
A support wheel apparatus for a towable disc system:
- a tire mounted to a hub;
- a movable arm connected to the hub;
- a wheel hydraulic actuator with hydraulic flow restriction, the hydraulic actuator attached to the movable arm to control the movement of the movable arm.
A rear tool attachable to a towable disc system, comprising:
- a soil working element;
- a positioning assembly mounted to the soil working element;
- a hydraulic actuator with hydraulic flow restriction, the hydraulic actuator attached to the positioning assembly to control the movement of the positioning assembly.
