Abstract:
1. A lawn mower attachment for a self-propelled lawnmower, comprising: a frame having a rear end, and two sides extending forward therefrom; brackets attached to forward ends of the two sides, the brackets being adapted for removable attachment to a rear portion of the self-propelled lawn mower; weight brackets adapted for attachment over rear wheels of the lawn mower, the weight brackets having a weight attachment boss for removable attachment of weights above the wheels; a U-shaped roller suspension member extending laterally between the two sides of the frame, the suspension member being pivotally attached to the two sides; a lawn conditioning roller, the lawn conditioning roller being removably attachable to ends of the U-shaped roller suspension member; torsion springs disposed between the frame side members and the U-shaped suspension member to provide a bias to keep the suspension member locked in an operable position when the suspension member is extended substantially perpendicular to the frame sides, the torsion springs also providing a bias to keep the suspension member locked in a retracted position when the suspension member is retracted to a position substantially parallel to the frame sides; and a control arm pivotally connected to the suspension member, the control arm being operable by a user to extend the suspension member to the operational position to engage the lawn conditioning roller to the ground, and, alternatively, to retract the suspension member to a stowage position to disengage the lawn conditioning roller from the ground.
