A tillage implement has a frame with a center section and first and second outer wing sections hingedly attached to respective outer ends of the center section. Controlling a pressure in a secondary side of a hydraulic circuit enables adjustment of the downward pressure precharge provided by hydraulic cylinders based on a desired stiffness of the implement. Flow from a hydraulic supply through a pressure-reducing valve puts the downward pressure precharge on gauge wheels. Once this desired downward pressure precharge has been achieved, flow from the hydraulic supply is shut off and a check valve holds the pressure such that the hydraulic cylinders hold the gauge wheels in the desired position.

An autonomous agricultural carrier vehicle, for carrying an agricultural implement includes a chassis with steerable wheels or tracks attached to a frame, wherein the frame includes a mounting apparatus for connection to the agricultural implement. The vehicle further includes an environmental sensor system for determining obstacles or elements present in the vicinity of the carrier vehicle and a control device for controlling the carrier vehicle or the at least one implement, wherein the control device is connected to a position determination system that captures and issues a position to create an autonomous agricultural carrier vehicle with which the impact force is not reduced. No additional tractor vehicle is needed for the implement and no operator is necessary during field work, wherein it is provided that position-dependent working instructions for the carrier vehicle are preferably stored in the control device.

A system for determining material accumulation relative to ground engaging tools of an agricultural implement may include a frame member, and first and second ground engaging tools coupled to the frame member. The first and second ground engaging tools are configured to engage soil within a field as the agricultural implement is moved across the field. The first and second ground engaging tools are electrically isolated from each other. The system may further include a power source configured to apply a voltage across the first and second ground engaging tools, a sensor configured to measure a capacitance across the first and second ground engaging tools, and a controller communicatively coupled to the sensor. The controller may be configured to determine a presence of material accumulation between the first and second ground engaging tools based at least in part on the measured capacitance.

A system, apparatus and method, for enhancing resolution during remotely controlled adjustment of a fore/aft trim angle of a frame of a towable tillage implement, utilize a fore/aft trim angle adjustment arrangement operatively attached between a hitch and the frame of the implement for tilting the frame at a desired trim angle along a fore/aft axis of the frame. An adjustable-length fore/aft trim linkage is operatively connected between the frame and the hitch for adjusting and maintaining the trim angle. A linear actuator is operatively attached to the trim angle linkage for remotely controlling the length of the trim angle adjustment linkage to thereby adjust the trim angle as a function of a stroke of the actuator. The fore/aft trim linkage provides an adjustment in its length that is proportionally less than the stroke of the actuator, to thereby provide enhanced resolution for remote control of the trim angle.

A system that includes a wheel carrier system. The wheel carrier system includes a wheel carrier arm that couples to a wheel and to a wheel carrier frame. A link rotates a ground engaging tool system with respect to a row unit to transition the ground engaging tool system from a lowered position to a raised position. An actuator that simultaneously rotates the first wheel carrier arm from a first position to a second position and the ground engaging tool system from the lowered position to the raised position.

A system for determining material accumulation relative to ground engaging tools of an agricultural implement includes a frame member extending along a first direction, first and second ground engaging tools coupled to the frame member, a sensing arm, a sensor, and a controller. The first and second ground engaging tools are spaced apart from each other in the first direction such that an open space is defined between the first and second ground engaging tools. The sensing arm is aligned with the open space defined between the first and second ground engaging tools and is displaceable, with the sensor being configured to detect displacement of the sensing arm. The controller is configured to monitor the displacement based at least in part on data received from the sensor to determine a presence of material accumulation between the first and second ground engaging tools.

An implement for tilling the soil and methods of using the same. The implement may include cultivator sweeps arranged in staggered rows, trailing coulters positioned behind a rearmost row of the cultivator sweeps, and a finishing attachment positioned proximate the trailing coulters. The trailing coulters are designed to penetrate deeper into the soil than the cultivator sweeps. The method includes passing such an implement through the soil such that the trailing coulters pass through the soil after the sweeps and the finishing attachment passes over and/or through the soil.
