Abstract: 1485047 Plows INTERNATIONAL HARVESTER CO 20 Aug 1974 [24 Sept 1973] 36576/74 Headings A1B A plow is formed in two (or more) sections 20, 120 pivoted together end-to-end about a horizontal transverse axis, the trip plow shares 80-95 being equally spaced. In Figs. 1 and 4 a tongue 131 projects forwardly from the frame member 121 of the rear section 120 and carries a tube 134 provided with plates 136 pivoted by bolts 71 adjustably carried by plates 67 secured to the arm 34 of the front section, 20. The plow sections 20, 120 may be prevented from pivoting (for transport independent of the tractor) by swinging a lock bar 140 forwards and pinning it to a lug 74. The plow is connected to the tractor draw-bar 11 by means of a hitch bar 38 pinned in a working or narrow transport position in a hitch member 36 pivoted to a frame beam 31. A hydraulic ram 51 is connected to the beam 31, and to a mast 43 on the hitch member 36 and also to linkage 50, 47, 48 supporting a castoring wheel 49, to raise and lower the front end of the plow. The centre of the plow is supported by a pair of wheels 60 which are carried by parallel links 55, 56 and a hydraulic ram 66, and which may be locked in a wide or narrow transport orientation. The rear of the plow is supported by a castoring ground wheel 151 carried by parallel links 152 and a hydraulic ram 153. Adjustable gauge wheel 150 only engages the ground during plowing. The lines of draft LD are each inclined at 6-12 (e.g. 6¢) to the horizontal. The plow bottoms 80-85, 90-95 and their associated coulter discs 87 are carried by overload trip mechanisms 86. In Figs. 7 & 8 (not shown), the centre of the plow is supported by a pair of ground wheels mounted on a bogie having a vertical spindle rotatably carried by a horizontal bar on the rear plow section which pivots the front and rear plow sections together. A hydraulic ram causes the plow sections to move up and down the vertical spindle. The bogie may be locked angularly in different steering positions. In Figs 9 & 10 (not shown), the horizontal bar on the rear plow section which pivots the front and rear plow sections together is cranked to support a steerable transport-only wheel. A hydraulic ram is connected between the front plow section and a lever projecting from the bar in order to rotate the bar and raise and lower the wheel. A fixed gauge wheel engages the ground during plowing and is carried at the rear of the front plow section. In Figs. 11 & 12 (not shown), the pivot between front and rear plow sections is higher, resulting in a line of draft that is too steep, but this is compensated for by a compression spring acting between the sections above the pivot. In Fig. 13 (not shown), a pair of steerable ground wheels are mounted on the front of the rear plow section by means of parallel links and a hydraulic ram.
