Abstract
A twin sickle drive system for a crop harvesting machine is disclosed wherein universal rotary input shafts are connected to each end of the upper conditioning roll to transfer rotational forces therefrom to individual wobble drive units situated along the outside of the machine to either side of the crop conditioning unit. Each wobble drive unit is connected to a drive shaft which transmits reciprocating motion to the sickle bar located adjacent that respective side of the machine.
