A security lock assembly includes a channel blocking frame, deadbolt and a pin-lock assembly. The channel blocking frame defines a central opening along a first axis and a pair of opposing apertures along a second axis orthogonal to the first. The deadbolt also defines an aperture or bore extending therethrough for alignment with the frame's opposing apertures when positioned at least partially within the central opening of the channel blocking frame. The pin lock assembly has an elongated shaft dimensioned to extend through opposing apertures of the lock frame and deadbolt thereby entrapping the deadbolt within the channel blocking frame. Enlarged ends of the pin lock assembly prevent unauthorized removal of the pin-lock, the deadbolt, and thus the installed lock assembly from a detachable assembly (e.g., plow). The security lock assembly when secured within an attachment channel of a plow prevents unauthorized attachment without first removing the security lock assembly. |
