A raking mechanism is disclosed which comprises a side delivery raking means mounted on a frame having three support wheels. The mechanism can be self-propelled or towed for raking and/or dethatching mowed lawns, with clipped foliage being discharged to one side and deposited in windrows. A steerable first support wheel is located toward the front end of the frame, whereas second and third support wheels are located adjacent the ends of a wheel suspension means that is pivotally attached to the rear of the frame. The second support wheel is mounted on a nonpivotable axle and rotates in a plane that is parallel to the line of draft of the mechanism, and the third support wheel is freely pivotable on a vertical axis. The side delivery raking means is immobilized against vertical movement with respect to the frame, but the rear of the frame can be electively raised or lowered to a preferred elevation for adjusting the height of the raking means relative to the surface of the ground.
