Abstract: A lawn aerator sulky adapted for attachment to a selflawn vehicle, such as a walk-behind mower or fertilizer spreader. The sulky includes a frame supported with wheels, a first platform on which an operator can stand and ride while not aerating, and a second platform carrying one or more aerator tine assemblies on its underside. The second platform and tine assemblies are moveable by the operator selectively transferring his/her weight to position the tine assemblies in a ground-engaged or ground-disengaged position. The sulky includes a device to support the second platform and its tine assemblies in the disengaged position when the operator steps off the platform, and a latching device to hold the second platform and its tine assemblies in the engaged position when the operator steps off the second platform.

Abstract: A mechanism for adjusting the height of a farm implement/tool of the type to be carried by a drawing vehicle includes a connector for supporting a farm implement/tool in an operative position. A guide directs sliding movement of the connector selectively between first and second positions corresponding to raised and lowered positions for a farm implement/tool which is carried by the connector. A mount connects the guide to one of a drawing vehicle and a support to be carried by a drawing vehicle. A lock fastens the connector in one of the first and second positions and selectively releases the connection to allow the connection to be slid into the other of the first and second positions therefor.
