| 摘要 |
The invention refers to an agricultural machine (1) for cultivation comprising a frame beam extending on both sides of a centre line in the driving direction of the machine, on which tools (11), preferably planter aggregates, are arranged at relative or group wise generally equal spacing. The agricultural machine has at least one joint for dividing the frame beam into frame beam sections (5, 6) and means (9) for swinging the corresponding frame beam sections on each side of said centre line through a generally equal angle in the horizontal plane, so that neighbouring tools in the working position on the frame beam sections always maintain a generally equal relative spacing. |
