Abstract
A leveling mechanism for harvester platforms or headers which is predicated upon the fact that a slight forcible distortion of the feeder housing to which the platform is secured will, when the distortion is effected in a particular manner, result in a side-to-side rocking motion of the platform. The mechanism for effecting such distortion is disposed immediately beneath the usual access door in the top wall of the feeder housing where it is readily accessible for manipulation, and locking means are provided for releasably securing the feeder housing in any of the distorted conditions of which it is capable of assuming.
