Abstract: 1388963 Combine harvesters DEERE & CO 14 Feb 1973 [14 Feb 1972] 7319/73 Heading A1F A crop-gathering unit 160 is detachably secured to a support frame 118, 124, 126 which may be tilted relative to the feeder house 78 of a hillside combine harvester about either one of pivots pins 122 resting in open recesses 134, by means of hydraulic cylinders 112, 114. The support frame 118, 124, 126 is guided during tilting by bolts 138 mounted in holes in the frame plates 124 and held captive in slots 136 formed in feeder plates 88, and also by rollers 152, 154 on U-members 146 extending into tubes formed by feeder plates 88 and mounting members 106. The self-levelling of the harvester is controlled by an attitude-sensing mechanism (not shown) which operates a solenoid valve 180 (Fig. 6) to supply pressure fluid to interconnected levelling cylinders 60L and 60R to swing wheel support arms 48 about pivots 46. Control cylinders 162, 164 are connected with lost motion between the harvester body 12 and the arms 48, and are connected to the tilting cylinders 112, 114. Operation: As the harvester moves from level ground to ground which slopes downwardly to the right, the solenoid valve 180 supplies fluid to the rod end of levelling cylinder 60L to raise the left wheel 14 and vents the rod end of levelling cylinder 60R to the reservoir 178. Fluid expelled from the anchor end of cylinder 60L passes to the anchor end of cylinder 60R to lower the right wheel 14. As fluid is supplied to cylinder 60L it is also supplied to the rod end of tilting cylinder 114 to keep the right-hand pivot pin 122 in its recess 134. As the wheel support arm 48R moves the wheel downwardly, control cylinder 164 is compressed and fluid is forced via line 196 to the anchor end of the tilting cylinder 112 to tilt the support frame 118, 124, 126 as shown in Fig. 5. Right-hand bolt 138 is moved into the inwardly-directed part of the slot 136 to hold the right-hand pin 122 in its notch 134. Bypass passages 200 are provided. Retraction of tilting cylinder 112 is limited by the extent of the extension of control cylinder 164 which is controlled by movement of the wheel support arm 48R. The lower edge of the crop discharge opening in the crop-gathering unit is always above the lower edge of the crop inlet opening in the feeder house.
