ABSTRACT:
A crop harvesting header drive mechanism is disclosed wherein a toothed drive belt transfers rotational power from a drive sprocket to a driven sprocket, both of which have indentations around the perimeter thereof to correspond to and engage with the drive belt teeth to provide a positive driving action. Shielding is provided for the return run of the drive belt, wherein the teeth are projecting upwardly, to prevent dirt and/or debris from filling up the interstitial spaces between adjacent drive teeth and disrupting the positive drive relationship between the drive belt and the drive and driven sprockets. The shielding mechanism is pivotally attached at its rearward end to permit the forward end to be vertically movable with the driven sprocket. A detachable L-shaped member is provided to close off a gap formed in the shielding for access to the drive belt.
