1 . A reversible mouldboard plough (1 ), wherein a plough beam (12) is provided with a pair of plough bodies (1 1 ), a skimmer arrangement (14) being connected to the plough beam (12) providing a first skimmer (141 ) and a second skimmer (141 a) proximate and in front of the respective plough bodies (1 1 ), wherein each skimmer (141 , 141 a) is attached to a skimmer shank (142) which is arranged displaceable in a longitudinal direction of the skimmer shank (142), and wherein the first skimmer (141 ) and the second skimmer (141 a) are interconnected with a synchronization mechanism (144) arranged to provide equal displacement of the skimmers (141 , 141 a) relative to the respective plough bodies (1 1 ), c h a r a c t e r i s e d i n that the first skimmer (141 ) and the second skimmer (141 a) are further interconnected with a linear actuator (15) arranged for displacing the skimmers (141 , 141 a) in the longitudinal direction of the skimmer shanks (142).

2. The reversible mouldboard plough (1 ) according to claim 1 , wherein the linear actuator (15) is electrically powered.

3. The reversible mouldboard plough (1 ) according to claim 1 , wherein the linear actuator (15) is connected to a control unit (16) arranged for remote control of the displacement of the first and second skimmers (141 , 141 a).

4. The reversible mouldboard plough (1 ) according to claim 1 , wherein the linear actuator

(15) is connected to a control unit (16) arranged for simultaneous remote control of the displacement of the first and second skimmers (141 , 141 a) of multiple skimmer arrangements (14).

5. The reversible mouldboard plough (1 ) according to claim 4, wherein the control unit (16) is arranged for individual remote control of the displacement of the skimmers (141 , 141 a) of each of the skimmer arrangements (14) of a multi-furrow reversible mouldboard plough (1 )-

6. The reversible mouldboard plough (1 ) according to claim 1 , further comprising a depth wheel (13) provided with a depth adjustment actuator (131 ) controlled by the control unit

(16) , and wherein the control unit (16) is arranged to allow a change of a vertical position of the depth wheel (13) providing a correlated change of the vertical position of the skimmers (141 , 141 a).

7. The reversible mouldboard plough (1 ) according to claim 1 , wherein the linear actuator

(15) is connected to mid-portions (1423) of the shanks (142) of the skimmer arrangement (14).

8. The reversible mouldboard plough (1 ) according to claim 1 , wherein the skimmer arrangement (14) is connected to a horizontal portion (121 ) of the plough beam (12) with a bracket (143) displaceable along said plough beam portion (121 ).

9. The reversible mouldboard plough (1 ) according to claim 1 , wherein the synchronization mechanism (144) is formed as a link-arm arrangement (144a) including a pivot arm (1441 ) pivotal around a centre axis and connected to upper second end-portions (1422) via link arms (1443).

10. The reversible mouldboard plough (1 ) according to claim 9, wherein a centre portion of the pivot arm is provided with an engagement portion (1442) arranged for connecting a manually operated skimmer depth adjusting tool to the pivot arm (1441 ).

1 1 . Method of setting the working depth of skimmers (141 , 141 a) of a reversible multi-furrow mouldboard plough (1 ) according to claim 1 , 4 and 6, c h a r a c t e r i s e d i n that the method comprises the steps of:

a) setting the working depth of the plough (1 ) by changing the vertical position of the depth wheel (13);

b) setting the working depth of the first and second skimmers (141 , 141 a) of the skimmer arrangements (14);

c) setting the control unit (16) to allow change of the vertical position of the depth wheel (13) providing a correlated change of the vertical position of the skimmers (141 , 141 a);

d) operating the plough (1 ) including changing the working depth of the plough (1 ), thereby simultaneously displacing the first and second skimmers (141 , 141 a) correlative^.

12. Method according to claim 1 1 , wherein the method comprises the further step of:

b1 ) setting the working depth of the first and second skimmers (141 , 141 a) of every one of the skimmer arrangements (14) individually.

13. Method according to claim 1 1 , wherein the method comprises the further step of:

b1 ) setting the working depth of the first and second skimmers (141 , 141 a) of every one of the skimmer arrangements (14) collectively.
