A grading blade attachment for a work machine comprising an attachment frame including an upper attachment frame portion and a rear attachment frame portion wherein the upper attachment frame portion has a frame length extending forward from the rear attachment frame portion. The attachment further includes a coupler bracket, a pivot beam, a left wheel assembly, a right wheel assembly, a grading blade, and a knock down blade. The knock down blade assembly is movably coupled to the upper attachment frame portion between an operative position and an inoperative position. The knock down blade assembly including a knock down blade positioned fore of the wheel assemblies connected to the upper attachment frame portion when in the operative position.

Disclosed herein are example box blade assemblies and foldable assemblies for use with the same. The foldable assemblies can have two or more segments which are pivotally connected to each other, such that the assemblies can be moved between an unfolded configuration and a folded configuration. In some cases, the foldable assemblies can include an actuator configured to extend and retract to move the assemblies between the unfolded configuration and the folded configuration. A locking mechanism may also be included to lock the foldable assemblies in the unfolded configuration, and in some cases, to lock the actuator into an extended position. The locking mechanism may also be engaged by the actuator. The actuator may be in communication with a controller that allows the user of a work vehicle to control the operation of the actuator and thus the foldable assembly.
