Synchronization Mechanism

An agricultural baler comprising:

• a baling chamber comprising a first segment and a plunger;
• a pre-compression chamber configured for gathering crop material, periodically forming a slice of the crop material, and pushing the slice towards the baling chamber into the first segment of the baling chamber;
• a controller;
• a slice-presence-detecting sensor disposed in an upper region of the first segment of the baling chamber, the slice-presence-detecting sensor comprising an output operationally connected to the controller;
• a plunger driving mechanism;
• a slice pushing driving mechanism;
• and
• an intermediary coupling element controllable by the controller, the plunger driving mechanism mechanically connected to the slice pushing driving mechanism via the intermediary coupling element,
• wherein the plunger is configured for reciprocally moving in the baling chamber to compress slices of crop material into a bale, and
• wherein the controller is configured for adjusting a synchronization between the plunger driving mechanism and the slice pushing mechanism.
