Abstract
A leveling arrangement for an agricultural implement frame having a draft tongue which is pivotally attached to a front end of the frame includes a rocker arm attached to the frame front end for pivoting about a transverse axis, a transfer link pivotally connected between a lower end of the rocker arm and a frame lift lever extending from the frame lifting rockshaft, and a leveling link pivotally connected between an upper end of the rocker arm and a front end of the tongue. Rotation of the rockshaft by the action of a hydraulic cylinder to lift or lower the frame is transferred through the leveling arrangement, by reaction against the pivoted hitch member, to the front end of the frame to respectively lift or lower the frame front end to thereby maintain a substantially constant pitch of the implement frame.
