What is the typical engine power range for a standard road grader?

The typical engine power range for a standard road grader is best represented by the range of 100 to 300 horsepower. This range is widely accepted in the industry, as it provides the necessary power for road grading applications, which often involve moving significant amounts of earth and material. A road grader's engine power is crucial because it directly affects the machine's ability to operate under various conditions, including different types of soil and material densities.

Engines within this power range are capable of providing the torque and thrust needed for effective grading, allowing operators to manipulate materials and create precise surfaces for roads and other infrastructure. As such, machines in this category are commonly found on construction sites and are designed to balance efficiency and power for standard grading tasks.

The other options mentioned either underrepresent or overestimate the typical engine power for road graders. The lower end of the power range, while functional for smaller tasks or lighter machinery, does not encompass the capabilities needed for standard road grading. Meanwhile, higher horsepower ranges are typically found in specialized or larger equipment designed for more extensive and demanding grading tasks, which is beyond the scope of what a standard road grader is designed to do.
