The invention relates to an agricultural machine comprising a first frame and at least one roller 4. The roller 4 comprises at least one tube rotatably mounted about a first axis XX on bearings connected to the first frame. The agricultural machine further comprises a second frame, connected to the first frame, and at least one wheel 5. The wheel 5 comprises at least one rim rotatably mounted about a second axis YY on bearings connected to the second frame. The wheel 5 is provided with at least one tire 51 threaded on the rim. The roll 4 has a bandage 42 around the tube. The tire 51 of the wheel 5 has a tread 52. The tire 42 and the tread 52 are provided with sculptures 43, 53 defining an elementary pattern 44, 54 repeated in a transverse direction parallel to the first axis XX, respectively to the second axis YY. The transverse repetition pitch L of the elementary pattern 44 of the roll 4, and the transverse repetition pitch L of the elementary pattern 54 of the wheel 5 are equal to 10%, The elementary patterns 44, 54 define ribs 45, 55 of which the height L on the roller 4 and the height L on the wheel 5 are equal to 90%, so that the repetition and the height of the ribs 45, 55 form in the earth 10 a series of grooves 11 substantially parallel and equidistant.L'invention concerne une machine agricole comprenant un premier bâti et au moins un rouleau 4. Le rouleau 4 comprend au moins un tube monté à rotation autour d'un premier axe XX sur des paliers reliés au premier bâti. La machine agricole comprend en outre un second bâti, relié au premier bâti, et au moins une roue 5. La roue 5 comprend au moins une jante montée à rotation autour d'un second axe YY sur des paliers reliés au second bâti. La roue 5 est pourvue d'au moins un pneu 51 enfilé sur la jante. Le rouleau 4 présente un bandage 42 autour du tube. Le pneu 51 de la roue 5 présente une bande de roulement 52. Le bandage 42 et la bande de roulement 52 sont munis de sculptures 43, 53 définissant un motif élémen
