Plough anchor comprising a neck portion through which an elongate shank is pivotally connected to the plough body

摘要

A plough anchor 30 comprises an elongate shank 32 and a plough body 34. The plough body has therein a neck portion 44 pivotally attached to the remainder of the plough body and through which the elongate shank is connected thereto. The axis y-y described by the pivotal connection of the neck portion and remainder of the plough body is tilted forward of the vertical such that upon rotation of the shank with respect to the plough body the shank is at its highest when not orientated along an axis o-o described by the plough body, i.e the axis y-y is oriented forwardly of the vertical which results in the first end 36 of the shank 32 being higher than the pivotal attachment between the shank 32 and the neck portion 44 upon rotation thereof away from the axis o-o. The neck portion of the plough body may be pivotally received on a shoulder plate 88 which is provides below an uppermost portion of a pair of blades 82 forming the plough body.
