An apparatus for trimming plant material includes a rotatable tumbler through which the plant material is to be axially propagated while rotationally tumbling, and a plurality of cutting reel systems adjacent the tumbler. The plurality of cutting reel systems includes a first cutting reel system adjacent the tumbler, and a second cutting reel system adjacent a landing zone of the rotatable tumbler. The landing zone is an angular range about the axis of the tumbler within which plant material tends to land on the tumbler after tumbling through a central volume of the tumbler.
