One embodiment of the present invention relates to a system for cannabis stem harvesting configured to specifically separate the leaves and buds from the stem. The system includes a frame member, die member, first rotating cylindrical member, second rotating cylindrical member, and a rotation system. The die member is coupled to the frame member and includes a plurality of orifices disposed within a plate. The first and second rotating cylindrical members are coupled to the frame member in a vertical configuration and oriented substantially adjacent to the die member. The vertical configuration of the first and second rotating cylindrical members defines a pinch region therebetween as a region across which a first and second circumferential surface of the first and second rotating cylindrical members are closest in proximity. The rotation system is coupled to the frame member and at least one of the first and second rotating members.
