Abstract

The pick-up head may include a plurality of tine bars for carrying a plurality of pick-up teeth. The tine bars may be rotatably supported by a drive shaft and the drive shaft may be secured to end plates of the pick-up head. The anti-wrapping device may be attached to an end of the tine bars to fill in gaps between the tine bars and to create a surface rotatable with the tine bars that is less susceptible to wrapping.
