An attachment for laterally shifting a working implement is provided. The attachment can have a primary frame having a first side and a second side, the primary frame can be connectable to the vehicle so that the primary frame extends substantially perpendicular to the vehicle. A secondary frame can have a first side and a second side and be moveably connected to the primary frame so that the secondary frame can move laterally relative to the vehicle. An extension frame can have a first side and a second side and be moveably connected to the secondary frame so that the extension frame can move laterally relative to the vehicle. A working implement, such as a mower, can be operably connectable to the extension frame so that the working implement can be shifted laterally relative to the vehicle using the attachment.
