An agricultural implement includes a frame carrying a toolbar, and row units coupled to the toolbar. Each row unit includes a tool support and a rotating support coupled to the tool support and configured to rotate about an axis of rotation. Ground-engaging tools are carried by the rotating support and extending outward from the axis of rotation. Rotation of the rotating support about the axis of rotation moves the ground-engaging tools around the rotating support to change which of the ground-engaging tools interacts with the ground. A method of adjusting the agricultural implement includes disengaging the row units from a ground surface, rotating at least one rotating support about a corresponding axis of rotation to move the ground-engaging tools around the rotating support, and re-engaging the row units with the ground surface.

Disclosed herein is a vehicle (1)—preferably a tractor—with a trailer (2) operatively connected thereto with a cardan (3), said cardan (3) comprising a power take-off, said power take-off being switched off when said cardan (3) builds with said vehicle (1) and/or with said trailer (2) an angle (ε) smaller than a first threshold value (a) and/or larger than a second threshold value (β) and being switched on when said angle (ε) exceeds again said first threshold value (β) thanks to suitable actuators, including detection means of the angle formed between the cardan (3) and said vehicle and/or trailer. According to the present invention, said angle (ε) is detected by a detector consisting of a magnetic device (4) placed on the trailer (2) or the vehicle (1) and an electronic compass (5) placed on the vehicle (1) or on the trailer (2). Preferably, the angle (ε) insisting on the cardan (3) is obtained according to the formula: ε=180−Y−arcsen (l/m sen y) (3) where y is the angle the compass (5) forms with respect to the straight travel with the magnet (4), I is the distance between the cardan (3) and the compass (5), m is the distance between the cardan (3) and the magnet (4).

An apparatus, which may be a tillage apparatus, is disclosed that may have a flexible frame. The frame may be made from open members. The frame may support ground engagers and may be supported on wheel assemblies. The ground engagers may be connected to a spring trip mechanism. The ground engagers may be mounted to open members of the frame with a clamping style mechanism. The clamp mechanism may include wedge devices. The frame may be lowered and raised relative to wheels of the wheel assemblies with a lift mechanism. One row of ground engagers may be raised or lowered relative to the frame independent of another row of ground engagers. An anti-skid or skew control system may be employed in association with the independent height adjustment of one row of ground engagers. A system may be provided to maintain and control the height of a tow hitch forming part of the apparatus.

A method for increasing the efficiency of farming operations used in the production of sown crops. In the proposed method for cultivating sown crops, all bar none of the technological operations which are carried out in the field, beginning from pre-sowing preparation and ending with the gathering of a harvest, make use of a self-propelled power-operated technological device capable of functioning on tires having a super-low pressure of 5-60 kPa and/or with a pressure on the ground of less than 60 kPa. The proposed method is realized with the aid of a transport and technological system primarily for farming purposes, that utilizes a self-propelled power-operated vehicle on tires of super-low pressure operating among others at a pressure of 5 to 60 kPa and/or exerting a pressure of less than 60 kPa on the soil. This vehicle is equipped with a discharging device and/or a lifting device.

A U-shaped support frame has a base beam and parallel side beams extending rearward from the base beam and defining an open implement area, which can be made adjustable. A hitch is attached to the front end of the support frame and frame wheels support the side beams, and rotate about a horizontal frame wheel axis that is fixed in an orientation perpendicular to the operating travel direction. Implements are configured to perform an implement operation and to rest on the ground surface when in an idle position. The support frame is moved rearward to a loading position where each implement is movable to an operating position supported by the support frame. Each implement provides a beam lock connection between the side beams that resists twisting movement of the side beams to maintain the frame wheels and the side beams in a substantially fixed relationship with respect to each other.
