9. A closing system for a work machine, the closing system comprising:
one or more closing devices that are operable to contact a ground surface;
one or more springs that are operable to apply an initial amount of force to the one or more closing devices;
an actuator that is disposed adjacent the one or more springs, the actuator operable to apply an actuator force to the one or more springs to increase the amount of force that the one or more springs apply to the one or more closing devices, wherein a stroke length of the actuator is adjustable to thereby adjust the amount of actuator force applied by the actuator to the one or more springs, further wherein the actuator is arranged so that adjustment of the stroke length of the actuator does not directly alter a position of the one or more closing devices;
an end plate configured to move relative to one or more springs to adjust the amount of force that the one or more springs apply to the one or more closing devices, the end plate includes one or more pin holes;
a shank plate having one or more holes therein, wherein the shank plate is assembled with the end plate such that one of the pin holes aligns with one of the holes in the shank plate; and
a pin received in the aligned pin hole and hole to attach the end plate to the shank plate.
