The Drift Cutter Kit is VERY STRONGLY RECOMMENDED for snow of 1 foot or more deep. The cutter bar installs on the pole just behind the Roof Razor head. It will vertically slice snow above the Roof Razor head and better allow it to fall into the created tunnel and down the snow slide.
THIS ACCESSORY IS EXTREMELY USEFUL IF YOU ANTICIPATE REMOVING ROOF SNOW OF 1 FOOT OR MORE DEEP. PLEASE CONSIDER YOUR NEEDS CAREFULLY AS A COMBINED PURCHASE WILL SAVE YOU ON SHIPPING.
