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.

An on-the-go monitor and control means and method for an agriculture machines includes on-the-go soil sensors that can be used to control tillage and seeding depth. On seeder implements, the sensors provide information that affects uniform plant emergence.

It is an object to secure a state where an operator easily reaches various operating means with a hand, and to reliably maintain an original function of an arm rest (to put the hand on the arm for rest). A working vehicle is configured such that speed of power from an engine provided in a traveling machine body is changed by a hydraulic continuously variable transmission, and the power is transmitted to a traveling unit and a working unit. An arm rest on which the operator's arm and hand are put is placed on a side of a cockpit in the traveling machine body. A main transmission lever which changes traveling speed by the traveling unit is arranged on a front end of the arm rest on the side of the cockpit. An elevating dial which hoists and lowers the working unit is arranged on a side surface of the arm rest on the opposite side from the cockpit.

An agricultural implement includes at least one row unit having a plurality of support members, each of which is pivotably coupled to an attachment frame or another of the support members to permit vertical pivoting vertical movement of the support members, and a plurality of soil-engaging tools, each of which is coupled to at least one of the support members. A plurality of hydraulic cylinders are coupled to the support members for urging the support members downwardly toward the soil. A plurality of controllable pressure control valves are coupled to the hydraulic cylinders for controlling the pressure of hydraulic fluid supplied to the cylinders. A plurality of sensors produce electrical signals corresponding to predetermined conditions, and a controller is coupled to the sensor and the controllable pressure control valves. The controller receives the electrical signals from the sensors and produces control signals for controlling the pressure control valves.

An agricultural implement including an implement frame, a trench opener, a gauge wheel arm and a depth adjustment assembly. A depth adjustment body is disposed between the depth adjustment assembly and the gauge wheel arm. An accelerometer is disposed on at least one of the depth adjustment assembly, the gauge wheel arm and the depth adjustment body and is configured to detect a position thereof. The accelerometer is disposed such that none of the x-axis, y-axis and z-axis of the accelerometer are perpendicular to the soil surface across the entire range of motion of the depth adjustment assembly, the gauge wheel arm or depth adjustment body to which the accelerometer is attached.
