position de lame

OBS: A chaque travail [de la niveleuse] correspond une position de lame optimum, (...) Ne jamais terrasser avec la lame perpendiculaire à l'axe de la niveleuse; ce n'est pas un bulldozer.

OBS: The blade of the motor grader can be held in positions like those of the angle dozer, bulldozer, or tilting dozer blade - all with greater flexibility of movement than the dozer. ... The versatility of the blade position does not mean that the motor grader can replace the various forms of dozer.
