ABSTRACT:
The horizontal diagonal angle (z) of the rear frame (16) of an articulated plow (11) is greater than the horizontal diagonal angle (y) of the front frame (14), thus providing a lead angle (x) between the frames (14, 16). This construction reduces the overcut by the plow bottoms (17) that would otherwise occur due to the lateral flexing of the rear frame (16). The lead angle (x) can be adjusted between predetermined minimum and maximum values by moving an eccentric (51) between predetermined positions of pivotal adjustment. The eccentric (51) is part of a pivot joint (33) which together with a pivot joint (32) establishes the transverse pivot axis (31) between the articulated plow sections (12, 13).
