  • Mechanism for selectively repositioning a farm implement
    Patent number: 5129282
    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.
