Blade assemblies having a plurality of teeth extending therefrom are useful for working soil and/or for removing objects buried under the surface of the ground. However, having a plurality of teeth extending below the blade assembly can be detrimental since ground clearance is reduced or if the blade assembly inadvertently lowers during movement of the vehicle from one job site to another. In the subject arrangement, a blade assembly is provided having a plurality of teeth extending therefrom. The plurality of teeth are retractable in response to movement of a mechanism within the blade assembly. Upon raising the blade assembly to its carry position with subsequent retraction of the plurality of teeth, a mounting bar assembly which is associated with the plurality of teeth is moved into a recessed pocket of a latching flange. The latching flange is attached to a vehicle by a frame assembly. This arrangement ensures that the blade assembly is maintained in its carry position by the retraction of the plurality of teeth. Furthermore, this arrangement retracts the plurality of teeth to a position generally within the blade assembly for added ground clearance.
