Snow and ice removal products clear off sidewalks, driveways, parking lots, and other surfaces to reduce hazards and leave a path for travel. Ice melt and traction control treat paved surfaces to dissolve ice and enhance grip to prevent slipping. Snow blowers have a powered auger to pick up snow from surfaces and discharge it into piles. Snow shovels and pushers use their blade to scoop up or move snow. Roof rakes pull down heavy snow loads before they cause structural damage to roofs. Ice scrapers and choppers drive into or under packed snow and thick ice to shave it off or break it up. Snow sweepers rotate their brush to scour off snow and slush for their plow blade to clear away.
