The present invention relates to a grading device adapted for easy and quick connection to a pulling machine, such as a tractor or dozer, utilizing two points of attachment provided by the pulling machine. The grading device has two main blades, each with an extendable blade to increase the contouring range. Each main blade is separated by an intermediate pivoting member, which enables independent movement of each blade. Accordingly, the device can crown or v-notch a loose surface in a single pass. Additionally, a remotely located joystick assembly enables control of the blades from an ergonomic position on the pulling machine.
