ABSTRACT:
An automatic height control for a gathering reel used with an agricultural combine of the type in which a floating cutter assembly and a gathering reel are carried by the header of the combine forwardly of the header. The control system of the invention adjusts the height of the gathering reel in closely tracking relation with vertical movement of the floating cutter assembly to thereby avoid damage to the gathering reel and to the cutter assembly due to interference between the cutter assembly and the gathering reel. The control system of the invention may be used in conjunction with a prior art header height control arrangement which responds to a predetermined vertical movement of the floating cutter assembly to vertically adjust the header and thus to vertically adjust the gathering reel carried by the header. However, the automatic height control of the invention requires a smaller increment of vertical movement of the cutter assembly for initiation of the gathering reel height adjustment than is required by the prior art header height control. The close tracking relation of the vertical position of the gathering reel relative to the vertical position of the cutter assembly provided by the control arrangement of the present invention permits location of the gathering reel closer to the cutter assembly and to the crop inlet end of the header, and in an optimum position for most effectively gathering the crop for cutting and for depositing the cut crop in the header of the combine.
