A mechanism for offsetting cutting units for a grass mowing machine includes lift arms that pivot between a first lowered position in which the cutting units are offset to the left of the traction vehicle, a second lowered position in which the cutting units are offset to the right of the traction vehicle, and a raised position intermediate the first and second lowered positions. Each lift arm has a first pivot axis and a second pivot axis parallel to the first pivot axis.
