Abstract
Agricultural machines and implements have a need to adapt to changing environments. A closing system for an agricultural machine has a need to adapt to changing ground surface. The closing system includes a closing device pivotably connected to the agricultural machine, a passive mechanical element that is operable to apply an initial amount of force to the closing device, and an actuator that is operable to apply an actuator force to the passive mechanical element to increase the amount of force that the passive mechanical element applies to the closing device. The actuator can be a linear actuator having an adjustable stroke length to vary the amount of actuator force applied to the passive mechanical element. The passive mechanical element is operable to absorb a shock force as the closing device traverses a ground surface. The passive mechanical element includes one or more springs adjacent the actuator.
