As adjacent blades from the upper and lower cutting rings are separated in an open position, plant material may be collected in the opening defined by the adjacent blades. As the blades converge, the opening may close, and plant material collected in the opening may be severed from the plant. System variables, may be adjusted to accommodate different types of plant material. The pruning system may be used with a vision system to remove materials from plant beds in a field.
