1. A harvester reel for an agricultural harvester header comprising:
(i) a central rotatable shaft;
(ii) a reel tine bar extending widthwise across the reel and connected to the central rotatable shaft for rotation therewith, the reel tine bar including a biasing member for biasing the reel tine bar to rotate about its central longitudinal axis, a follower operatively connected to the reel tine bar, and a tine; and
(iii) a cam assembly including:
a primary cam,
a linkage having a first end that is connected to the primary cam and a second end that is configured to be releasably connected to the tine bar for guiding rotation of the tine bar about its central longitudinal axis during rotation of the central rotatable shaft,
a latch for releasably connecting said second end of the linkage to the tine bar, wherein in an unlatched configuration of the latch, the reel tine bar can pivot relative to the second end of the linkage, and in a latched configuration of the latch, the reel tine bar is non-rotatably connected to the second end of the linkage, and
a secondary cam having a surface that is configured to be contacted by the follower of the reel tine bar, wherein upon contacting the secondary cam, the follower moves the latch from the latched configuration to the unlatched configuration.
