This document discusses different types of snow plows and their designs. There are three main types: commercial snow plows for large roads and parking lots, residential plows for driveways and sidewalks, and all-terrain plows for occasional or light snow. Snow plow designs include manual plows that attach to vehicles' receiver hitches, electric plows that are electronically controlled from inside the cab, and hydraulic plows that use hydraulic fluid pressure for control. The document provides an overview of snow plow options to help buyers choose the appropriate type and design.
