The Boss RPL21615B is a Drag Pro Fixed Wing. The new BOSS DRAG PRO™ brings all of the power and productivity of BOSS plows to the back of your truck. It mounts from the rear to pull snow from the back. Back in, drop the plow, pull forward, and start saving time and money. Expand the hydraulic folding wings to tackle more snow with each pass, all with a standard 3/4-ton truck. The down force of the plow helps the DRAG PRO scrape more cleanly and efficiently than traditional plows, especially in wet snow. Pair with a BOSS v-plow, straight-blade plow or EXT plow for the ultimate expanding plow rig and a huge boost in productivity built to BACK YOU UP.
