Abstract
A multi-piece tool bar assembly including a main support structure suited for connection to a frame of an agricultural implement and a second support structure selectively attachable in end-to-end abutting relation with the main support structure for extending the effective length of the tool bar assembly. A fastener assembly initially aligns support surfaces on the support structures relative to each other and thereafter maintains such alignment to facilitate movement of one or more row units onto the second support structure. The fastener assembly is arranged wholly within the exterior of the support structures and comprises a guide pin which extends beyond an abutting end of one of the support structures and is accommodated in a close sliding fit relationship within an opening defined at the abutting end of the other support structure. The guide pin and opening are precisely located on the respective support structures to ensure alignment of the support surfaces of the support structures. Threaded fasteners releasably interconnect the support structures to each other and furthermore maintain the support surfaces in alignment relative to each other.
