Rotor Assembly for an Agricultural Baler

A rotor assembly for an agricultural baler. The rotor assembly has a rotor shaft having a central portion and first and second end portions either side of the central portion. The rotor assembly further has a number of tine plates to be arranged axially along the rotor shaft, each of the tine plates having one or more tines. The tine plates are arranged such that there is an angular spacing between the tines of adjacent ones of the tine plates. A magnitude of the angular spacing is greater or smaller at the central portion than at the first and second end portions of the rotor shaft. This can help to ensure that collected crop is more evenly distributed when it is moved into a pre-compression chamber of the baler in the case of relatively narrow or wide windrows, in particular that the crop that fills the sides of the pre-compression chamber is optimal, which means that a desired bale shape and bale rate may be more readily achieved.
