Mechanical linkage for agricultural accumulator including extendable carriages

An accumulator coupled to an agricultural baler, the accumulator configured to support a crop package exiting the baler, the accumulator comprising:

• a frame including a first end, a second end, and a support surface positioned between the first and the second ends, the support surface configured to support the crop package that exits the baler;
• a carriage coupled to the first end of the frame and moveable relative to the frame between a retracted position and an extended position, the carriage configured to support the crop package when in the extended position;
• and
• a linkage coupled to at least one of the frame and the carriage, the linkage configured to move the carriage to the extended position, the linkage configured to retain the carriage in the retracted position.
