ABSTRACT:
An articulated plow has a front section 12 supported at its front end by a ground engaging furrow wheel 19, a rear section 13 supported at its rear end by a ground engaging furrow wheel 22, pivot joints 32, 33 interconnecting the diagonally disposed frames 14, 16 of the end-to-end front and rear sections 12, 13 on a transverse articulation axis 31 and central support wheels 23, 24 which contact the ground forwardly of the articulation axis 31 to produce a counter moment acting on the rear section 13 to counteract the tendency of the rear plow bottoms to operate at a reduced plowing depth.
