disconnecting the thermal liquid tubing of the drive unit from the set of fluid couplers of the mowing unit;
disconnecting the electric wiring of the drive unit from the mowing-unit electric motor of the mowing unit;
disengaging a set of drive-unit mechanical-engagement structures of the drive unit from a set of mowing-unit mechanical-engagement structures of the mowing unit;
positioning the mowing unit away from the drive unit aligning the additional mowing unit with the drive unit;
engaging the set of drive-unit mechanical-engagement structures of the drive unit to a set of additional mowing-unit mechanical-engagement structures of the additional mowing unit;
connecting the electric wiring of the drive unit to an additional mowing-unit electric motor of the additional mowing unit;
