A tillage control system for a plurality of row units having an implement and being connected to a frame is disclosed. The system includes a hyrdaulic system having fluid, a supply port and a drain port. A plurality of control subsystems are fluidly coupled with the supply port and the drain port. Each control subsystem is coupled with one of the plurality of row units and include a control valve and an actuator fluidly coupled to the control valve. The system further includes a controller communicatively coupled with each of the control valves to independently operate each actuator to raise and lower each implement of the plurality of row units relative to the frame.

In one aspect, a system for reducing variations in the penetration depths between ground-engaging tools of an agricultural implement may include an implement having tires spaced apart from each other. The system may also include pressure sensors provided in operative association with the tires, each pressure sensor being configured for detecting an air pressure within the associated tire, Additionally, the system may include a controller communicatively coupled to the pressure sensors. The controller may be configured to monitor an air pressure differential between a pair of tires based on measurement signals received from the pressure sensors. The air pressure differential may be indicative of variability in the penetration depths of the ground-engaging tools. Furthermore, the controller may be configured initiate a control action associated with reducing the variability in the penetration depths of ground-engaging tools when the air pressure differential exceeds or falls below a predetermined tire pressure differential threshold.

An attachable tilling device for a vehicle is provided. The device includes a housing having a base member, wherein a pair of opposing side members extend downwardly from a first end and a second end thereof. A bar member is rotatably affixed between the pair of opposing side members, wherein the bar member rotates about a longitudinal axis. The bar member includes a plurality of tilling blades affixed thereto. A gear system is operably connected to the bar member, wherein the gear system rotates the bar member. A gearbox is disposed on an upper side of the housing, wherein a pair of shaft members are operably connected to the gearbox, wherein a first shaft member connects to the gear system and a second shaft member connects to a motor, such that when the motor is actuated, power is transferred to the gearbox, thereby rotating the plurality of tilling blades.

A remotely positionable stabilizer wheel arrangement for a towable agricultural implement utilizes an electronic control unit that receives an input signal indicative of a desired position of the stabilizer wheel, and/or a desired depth of penetration of tillage tools operatively attached to the front and rear of the implement frame, to automatically control an electrically powered linear actuator of the remotely positionable stabilizer wheel arrangement to position and hold the stabilizer wheel at the desired position of the stabilizer wheel.

An agricultural implement system includes a down force cylinder configured to apply a downward force to a row unit, and a depth control cylinder configured to vary a penetration depth of a ground engaging tool of the row unit. The agricultural implement system also includes a valve assembly in fluid communication with the down force cylinder and the depth control cylinder. The valve assembly is configured to automatically adjust the downward force by varying fluid pressure within the down force cylinder based on fluid pressure within the depth control cylinder.

A width-variable tillage device is provided with a frame and a leading four-bar first guide mechanism connected to the frame. The first guide mechanism has a depth guide element which regulates a height of the first guide mechanism above the ground, and an actuator which actuates the height of the first guide mechanism between a working position close to the ground and an elevated position remote from the ground. The tillage device further has a trailing second guide mechanism connected to the frame and having at least one tool for tillage, and a connecting member which connects the first and second guide mechanisms such that the second guide mechanism follows the height of the first guide mechanism and can be moved in a transverse direction. Furthermore, the tillage device has a width adjustment unit which can adjust a distance in the transverse direction between the first and second guide mechanisms.

Systems and methods for tilling ground material are provided. According to one embodiment, a tiller system is provided comprising two coiled conical blades that penetrate ground material to provide both forward propulsion and tillage of the ground material. An operator of the tiller system can adjust the angle at which the coiled conical blades penetrate the ground material to achieve an optimal balance of forward propulsion, stability, and tillage of the ground material.

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.
