A link assembly (3) for an agricultural ground engaging chain (1) including a plurality of said link assemblies (3), the link assembly including: a first component (7) having a first clamping portion (21) and a first link portion (13) for linking with a link portion of an adjacent link assembly; a second component (9) having a second clamping portion (27) and a second link portion (15) for linking with a link portion of an adjacent link assembly; a resilient harrow member (5), wherein the resilient harrow member (5) is elastically deformable; and at least one fastening element (11). When the link assembly (3) is assembled, the resilient harrow member (5) is clamped between the first clamping portion (21) and the second clamping portion (27) under an applied pressure, elastically deforming to enable engagement of the at least one fastening element, whereby upon release of the applied pressure, the resultant elastic stress in the harrow member (5) urges the first (7) and second (9) components to bear against th
