A pick system includes a holder and a pick assembly. The holder includes a first end, a second end, and a bore extending between the first end and the second end and defining a longitudinal axis. The surface of the bore may be tapered so that the diameter of the bore proximate the first end is greater than the diameter of the bore proximate the second end. The pick assembly includes a shaft. The shaft is received within the bore of the holder along the longitudinal axis, and the shaft may be tapered to mate with the bore.

A conveying arrangement conveys loose material in a conveying direction, in particular agricultural material. Several knives of a cutting assembly are mounted below a cutting area guiding surface. The material is first conveyed along the cutting area guiding surface and afterwards along a further guiding surface. Both guiding surfaces are mechanically supported by a connecting assembly. A positioning mechanism can pivot the connecting assembly upwards and downwards. This pivotal movement causes both guiding surfaces to be moved upwards and downwards. The cutting area guiding surface together with the cutting assembly can be shifted laterally, i.e. perpendicular to the conveying direction, and is guided during this lateral movement.

A bale shredder may comprise a bale hopper defining an interior bale chamber for receiving a bale to be shredded, a bale shredding assembly to shred a bale in the chamber including a shredding rotor having a plurality of flails to contact a bale in the bale chamber, and a passage for receiving material shredded by the shredding rotor. In embodiments, a conveying assembly may facilitate material flow through the passage with a moving conveying surface. A collecting auger assembly may collect material ejected by the shredding rotor through the passage and may include an auger with an auger shaft rotatable about a rotation axis. In embodiments, a discharge assembly with a discharge rotor configured to receive the shredded material from the collecting auger assembly and expel the material through a discharge opening, and the discharge rotor may rotate on the auger shaft of the collecting auger assembly.
