The invention relates to a driver (2) and a driver arrangement (1) comprising two drivers (2) for a link chain (7), particularly of a chain conveyor, moved in a chain direction (8). The driver (2) is provided with a base body (4) extending in the chain direction and with a beveled driver horn (3) angled away from the base body, said driver horn being insertable into the clear inner chamber (5) of a chain link (6). The driver horn (3) is beveled at an angle away from the base body. The base body has a contact and displacement surface (18) for an additional driver (2), said surface running substantially parallel to the chain direction. In order to increase durability while at the same time preserving a simple structure and without increasing installation expense, the invention provides for the contact and displacement surface (18) to be at least partially delimited by a support section (23) of the base body protruding substantially perpendicularly to the contact and displacement surface (18) on the side of said surface facing the link chain (7).
