One embodiment includes a grading tool structured for attachment to a work machine. The grading tool includes a frame, ground contacting wheels coupled with the frame, a comb coupled with the frame and extending from a first end of the frame, and a coupling member coupled with the frame and structured to be accessible from a second end of the frame. When the ground contacting wheels are in contact with the ground a depth of penetration of the comb into the ground surface is adjustable by changing the pitch of the grading tool.
