Die 1 zeigt einen Hydraulikschaltplan für die Hydraulikzylinder 1 und 2 Spuranreißern einer landwirtschaftlichen Verteilmaschine mit einem Fahrgassenmarkierungsventil 3. An das Markierungsventil 3 sind mittels der Leitung 4 und 5 die nicht dargestellten Spuranreißern einer Verteilmaschine zugeordneten Hydraulikzylinder 1 und 2 angeschlossen, so dass die Hydraulikzylinder 1 und 2 wechselseitig anhebbar und absenkbar sind. Das Fahrgassenventil 3 ist über die Zuleitung 6 an ein Schaltventil 7 der Schlepperhydraulikanlage 8 angeschlossen. Durch die Druckbeaufschlagung der Leitung 6 durch die Schlepperhydraulikanlage 8 schaltet das Gasmarkierungsventil 3 um, so dass beim nächsten Drucklosschalten der andere Spuranreißer über den zugeordneten Hydraulikzylinder abgesenkt wird.The 1 shows a hydraulic circuit diagram for the hydraulic cylinder 1 and 2 Track markers of an agricultural distributor with a tram marking valve 3 , To the marking valve 3 are by means of the line 4 and 5 the track markers, not shown, of a distributor associated hydraulic cylinder 1 and 2 connected so that the hydraulic cylinder 1 and 2 are mutually raisable and lowerable. The tramline valve 3 is over the supply line 6 to a switching valve 7 the tractor hydraulic system 8th connected. By the pressurization of the line 6 through the tractor hydraulic system 8th switches the gas marking valve 3 at, so that is lowered at the next depressurization of the other track marker on the associated hydraulic cylinder.

Zwischen den beiden vom Gassenventil 3 zu den jeweiligen Hydraulikzylindern 1, 2 der Spuranreißer führenden Leitungen 4, 5 ist die Verbindungsleitung 9 angeordnet. In der Verbindungsleitung 9 ist ein mittels eines nicht dargestellten Betätigungselementes fernbetätigbarer Absperrhahn 9 angeordnet. Wenn der Absperrhahn 10 geschlossen ist, werden die Spuranreißerzylinder 1, 2 und somit die Spuranreißer wechselseitig über das Gassenventil 3 eingefahren oder ausgefahren.Between the two from the lane valve 3 to the respective hydraulic cylinders 1 . 2 the track marker leading lines 4 . 5 is the connection line 9 arranged.
