Abstract
An agricultural implement connection assembly. The assembly has a plurality of hooked tongues secured to a four bar parallel linkage associated with an agricultural implement. The tongues are designed to fit into mating engagement with a similar plurality of grooves defined by a frame coupled to an agricultural vehicle. Hydraulic lines from the agricultural vehicle are coupled to the agricultural implement to lift the agricultural implement into mating engagement with the grooves and then lowered until the hooks engage cleats provided at the tops of the grooves. A locking pin assembly is provided through the groove frames and tongues to secure the tongues within the grooves. The locking mechanism has a spring actuated bias system which maintains the locking pins out of engagement with the tongues for attachment and detachment, and also biases the locking pins into engagement with the tongue during transport, storage and use of the agricultural implement.
