Abstract: An agricultural baler comprises a baling chamber and pick-up device for collecting crop material from a field and feeding it to conveyor mechanism which transports it into the baling chamber. A plunger reciprocates therein for compressing the crop material to a package and a tying mechanism encircles the package with one or more strands of tying material, thereby forming a completed bale. The baler comprises bale discharge device disposed at the outlet of the baling chamber, the bale discharge device being movable between an extended position for receiving the completed bale and depositing it onto the field and a retracted position for reducing the overall length of the baler. In the retracted position, a rear portion of the bale discharge device is rested on a support on top of the baling chamber. The discharge device are held in their retracted position by the rear portion itself.

Abstract: A baler comprises means for securing a completed bale of material and metering means for triggering the operation of the securing means. The metering means includes a pinion drivingly connectable with a trip arm. Relative driving movement between the trip arm and the pinion takes place on rotation of the pinion until the pinion engages a recess in the trip arm, at which point, operation of the securing means is triggered. The extent of the relative driving movement between the trip arm and the pinion is representative of a dimension of the bale being formed. The metering means further comprises a roller mounted on the trip arm at the entry of the recess for engaging the pinion when the pinion is at the point to enter the recess thereby breaking the driving connection between the pinion and the trip arm.
