Taking into consideration the conditions in the field in terms of the type of soil and its characteristics, it may be necessary to adjust the furrow width accordingly to achieve the ideal working results. Depending on the point-to-point spacing, different furrow widths can be achieved.
To achieve a consistent turnover of the furrow ridge, the furrow width needs be adapted when the furrow depth is changed, in order to ensure a constant ratio of ploughing depth to furrow width.
It is also possible to change the formation of the furrow ridge for agronomic reasons by changing the furrow width.
Adapting the furrow width on SERVO ploughs using the PLUS hydraulic furrow width adjustment system is easy, convenient and can be done on the move. This is so convenient that it allows the furrow width of the plough bodies to be adjusted without the need for tools. The disc coulters and the depth wheels are also adjusted automatically.
To manage this, the tractor requires a double-acting spool valve. Once it has been set to the inside track width of the tractor, the front furrow width is automatically adjusted when the furrow width is changed. This is done by the four-joint linkage at the control centre in accordance with the remaining furrows.
The furrow width of each body on ploughs with hydraulic furrow width adjustment is controlled indirectly by a lever actuated by a hydraulic cylinder. When actuated, every change in the hydraulic cylinder is transmitted extremely smoothly and precisely to the plough body by the furrow width control lever.
On the PLUS adjustment system, the plough body pivot points are located alongside the plough beam tube. This means that no large holes are required through the tube, increasing plough beam strength. For an extended service life, the bearings of the pivot points are designed to be lubricated.
On SERVO ploughs without hydraulic adjustment of the furrow width, the plough bodies are adjusted manually. This is done to match on-site requirements using a bolt and a hole matrix.
