Agricultural tillage implement and assemblies

An agricultural tilling device comprising:

• a central portion that defines a rotational axis about which the device is configured to rotate in use;
• and
• a plurality of tilling members that in use of the device are configured to engage the ground, each tilling member projecting generally radially outwardly with respect to the rotational axis from an inner end that is connected to the central portion, to an outer, ground engagement end that defines a radially outer peripheral edge of the tilling member,
• wherein each tilling member is configured such that at least one tangential plane, which is substantially coincident with the respective radially outer peripheral edge, is oblique to the rotational axis of the device,
• wherein the radially outer peripheral edge of each tilling member has a single tangential plane, and the tangential planes of all the tilling members are arranged at a common angle to the rotational axis, and
• wherein the tangential planes of all the tilling members are arranged at an angle to the rotational axis that is either less than 45° or greater than 45°.
