A walk-behind saw is a type of cutting tool designed for large-scale concrete or asphalt projects. It features a powerful engine and a diamond blade, allowing operators to make precise cuts in hard surfaces. The saw is pushed along by the operator, who walks behind it, making it easier to maneuver over long distances. These saws are commonly used in construction and road maintenance, where they can efficiently create expansion joints or repair surfaces. Their design often includes adjustable cutting depths, making them versatile for various applications. Safety features are also included to protect the operator during use.
