What is the primary purpose of a sharp angled blade on a grader?

The primary purpose of a sharp-angled blade on a grader is indeed for ditching. This design allows the blade to slice through the earth and effectively create ditches or drainage channels. The sharp edge helps in cutting into the soil or materials with precision, making it easier to shape the ground for water drainage purposes, which is crucial in preventing flooding and maintaining road stability.

While leveling soil, cutting asphalt, and moving dirt are tasks associated with graders, they are typically accomplished using different blade configurations or tools. For example, leveling soil generally uses a flatter blade angle to ensure an even surface. Cutting asphalt often requires specific blades or attachments designed for that particular material. Moving dirt can be achieved with various angles of the blade, but the sharp-angled configuration specifically excels in creating ditches or channels where an effective cut is needed.
