Abstract: An agricultural baler. The agricultural baler includes a baling chamber including a first segment, a plunger, and a baling chamber. The agricultural baler further includes a controller and 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. The agricultural baler further includes 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. The plunger is configured for reciprocally moving in the baling chamber to compress slices of crop material into a bale. The controller is configured for adjusting a synchronization between the periodically forming and pushing of the slice in the pre-compression chamber and the reciprocally moving of the plunger.

Abstract: A tying mechanism for a baler, operable to produce two successive knots in a pair of strands during one full operating cycle of the tying mechanism; the mechanism comprising a twine holder for maintaining the pair of strands in a suitable position throughout the complete formation of a first one of said two successive knots and to continue to maintain the pair of strands in a suitable position during the initial stage of the formation of a second one of said successive knots, and a cutter co-operating with the twine holder for severing the strands during formation of said first one of said two successive knots. The tying mechanism further comprises releasing means to release said pair of strands from the twine holder before full completion of said second one of said two successive knots. No twine tails will be formed, preventing knotter problems occurring during the baling process. Also environmental pollution will be prevented since no twine tails will be removed from the baler.
