The present invention provides a planar tine plate having a number of tines. The tine plate is for arranging on a rotor shaft of a rotor cutter apparatus of an agricultural baler. The tine plate is for moving or conveying crop material collected by the agricultural baler, for example by pickup apparatus of the agricultural baler. The tine plate has at least one first tine and at least one second tine spaced angularly from the at least one first tine. The at least one first tine has a length greater than that of the at least one second tine. The invention is advantageous in that, by providing a tine plate with tines of different size around its circumference, an increase in the cleaning efficiency and the crop conveying efficiency of an area to be swept by the tine plate as the rotor shaft rotates may be achieved.
