Which tool should be used to cut finish grade?

Bobcat
Excavator
Road grader
Backhoe

The correct answer is: Road grader

A road grader is specifically designed for grading and finishing surfaces, making it the most suitable tool for achieving a precise finish grade. Its long blade can be adjusted to optimize the level and smoothness of the surface, which is crucial in preparing for various applications, such as paving roads or laying foundations. Road graders are particularly effective at distributing materials evenly, thereby producing a consistent and level finish on grading projects. In contrast, while a bobcat, excavator, and backhoe can perform various earth-moving tasks, they do not provide the same level of control and precision for finish grading as a road grader. Bobcats are largely used for smaller sites and can dig or lift but are not ideal for large-scale grading. Excavators excel at digging and moving large amounts of material but are less efficient for fine grading tasks. Backhoes are versatile but tend to be less efficient when it comes to achieving fine finishes compared to the specialized capabilities of a road grader.
