ABSTRACT:
The invention relates to a device for straightening combine rasp bars mounted on a rasp bar wheel. The device includes a bar having at one end a surface designed to engage the rasp bar axle. The other end of the bar is telescopingly received in a sleeve having located therein a bolt for adjustably positioning the bar within the sleeve. Attached to the outside of the sleeve is a wedge which serves to engage the inner side of the rasp bar so that the rasp bar may be bent outward to its original position by use of the positioner between the bar and the sleeve. Attached outwardly of the engaging wedge on the sleeve is an underslung receiving pocket which receives a crossbar having at either end bolts which may be used to force the rasp bar inward.
