I installed the scarifiers on mine this weekend to breakup the ice from a rain event last week. Helped with the driveway that had turned into an ice rink.
box blades work pretty good for pulling snow forward from garage doors and the like plus if you plow forward with the bucket then just drop the box and plow in reverse. A tractor with a stout 3 point is probably a good idea though since pushing on the 3 point arms in reverse puts a lot of strain on them.
Double bladed Boxes should plow in reverse much better than a single blade box.
