A walk-behind lawn aerator has a left and right aerator reels both journalled side by side on the same axle and rotatable independently of one another. Left and right hydraulic drives provide motive power to the left and right reels, and each is capable of rotating the associated reel forward, reverse, or at intermediate speeds. A wheel boom carries front wheels, and is raised and lowered using a hydraulic cylinder. With the wheel boom lowered, the unit is capable of a zero-radius turn.
