Abstract
A snap-away auxiliary tine for harvester reels. The tine is attached to its supporting shaft by a split cylinder which partially encloses a shaft fitting. Rounded axial grooves in the inside of the split cylinder interlock with splines on the shaft fitting and prevent normal rotation of the tine. Extreme force on the tine, such as that when the tine hits a hard object, causes the split cylinder to spread slightly, disengage the grooves and rotate on the shaft, thus preventing tine breakage. Manual rotation repositions the tine.
