Abstract: Work vehicles, such as construction vehicles, include an attachment tool to transport material. The attachment tool is coupled to a lift arm assembly of the construction vehicle via a coupling assembly. The coupling assembly is designed to be coupled to any one of a variety of attachment tools. However, coupling assemblies commonly utilize coupling pins to couple the attachment tool to the lift arm assembly. The coupling pins are onerous to insert/remove and prone to rusting. Furthermore, the coupling assemblies often have too much lateral tolerance. As such, the attachment tools are prone to lateral movement relative to the lift arm during operation. Therefore, an attachment tool coupling assembly for a construction vehicle is needed to easily couple and release the attachment tool from the lift arm assembly and prevent lateral movement of the attachment tool relative to the lift arm assembly.
