Improvement to a machine for harvesting and processing grain, having a structural part defined as a chassis (1) supported on a pair of wheels (2), constituting a cart structure, the front part of which projects in a spear-like configuration with universal connection (3), in the proximity of which there are two assemblies, the first of which is a vertical resting foot (4), placed to the side, and the second of which is a Cardan shaft (5) that, via the front end, can be coupled to the power take-off of a conventional tractor, whereas, at the other end, said shaft is connected to a transmission (6) that actuates the second Cardan shaft (7), there being, under the latter, an intake tunnel (8) for material to be processed, which is equipped with an intake opening (9), lateral guides (10), rollers (11), a harvesting roll (12), screen (13) and entraining apron (14), interacting in order to pick up the branches and entrain them onto said screen (13), feeding same inside a transverse compartment (15) in the front part of the chassis (1), where a compressor cylinder (16) is housed that, in conjunction with screens (18-19) and beater cylinder (20), separates the grain for final cleaning in a suction duct (22), after which the clean grain falls into a transverse trough (24) for collecting grain, with a conveyor screw (25) that, in turn, ends at a lateral point on the machine and, from that point upwards, there is a chain, scoop elevator (26) that, lastly, ends over a rocking container skip (27).L'invention concerne une amélioration apportée à une machine de récolte et de traitement de grains, comprenant une partie structurale définie comme châssis (1) en appui sur une paire de roues (2) constituant un véhicule tracté, dont la partie avant se prolonge pour former un organe d'accouplement universel (3), au voisinage duquel se trouvent deux ensembles, le premier étant un pied d'appui latéral et vertical (4) et le second étant un arbre de transmission longitudinal (5) qui, par l'ex
