Abstract:
1. A drive for transferring sideward motion from a first elongate sickle cutting knife on a header of an agricultural combine to a second elongate sickle knife on the header, the sickle knives being mounted in substantially longitudinally aligned relation along a sidewardly extending forward portion of the header for sideward motion relative thereto, the drive comprising: a double rack and pinion arrangement including at least one pinion mounted at a fixed location on the forward portion of the header, a first sidewardly extending rack connected to the first sickle knife for sideward movement therewith enmeshed with the pinion, and a second sidewardly extending rack connected to the second sickle knife for sideward movement therewith enmeshed with the pinion opposite the first rack, such that when the first sickle knife is moved reciprocally sidewardly relative to the header, the first rack will move correspondingly reciprocally sidewardly to reciprocally rotate the pinion so as to reciprocally sidewardly move the second rack and the second sickle knife oppositely to the reciprocal sideward movement of the first rack and the first sickle knife.
