ABSTRACT:
A cast prickle chain link element, and a prickle chain made by interconnecting a plurality of these links. Each link element includes a body, the body having at least one hole, and at least one hook formed into it, and at least one ground engaging finger projecting outwardly from the body. The hook formed into the body of one element, is adapted to engage the hole formed into the body of another identical element, thereby facilitating the linking of elements in order to form a prickle chain.
