A tine assembly is used with an agricultural machine such as a harvester or hay merger. The tine assemblies mount on a reel that rotates about an axis extending transverse to the direction of travel. The tine assembly includes a first tine and a second tine, each having a main extended portion and a lateral portion extending transverse to the main portion at a mounting end of the tines. The lateral portions mount into tabs or opposite ends of a sleeve. The sleeve or tabs and mounting end of the tines are enclosed by a molded mounting portion that also includes a reinforcing arcing element configured for mounting to the reel bar. The arcing element includes orifices that allow for easily bolting and unbolting the tine assemblies for easy attachment and removal.
