ABSTRACT:
Locking structure for a harvester basket having an upper basket portion telescopingly received within a lower basket portion. Channel lock-ups are located at three of the four corners of the basket. Each lock-up includes two channels, one channel having a length equal to the extension length of the upper basket portion and the other half that length. The two channels are connected together by a pivot pin in the middle of the long channel. One end of the long channel is connected by a pivot pin to the basket and one end of the short channel is connected by a pivot pin to the top of the upper basket portion. As the upper basket portion is raised or lowered, the channels pivot about the middle of the long channel. Approaching the raised position, the upper portion of the long channel may be used as a lever to urge the upper basket to the final extended position. The upper channel portion is received against the upper portion of the short channel, and a quick-lock pin is inserted through the upper ends of the channels adjacent the upper edge of the basket to secure the basket in the telescoped position.
