HP refers to “High Performance” and represents the Centurion Pro workhorse line of buckers, which include single and triple-workstation options. The HP line utilizes two rollers that pull the stem into the machine, therefore popping the flowers off. This allows you to continuously feed the bucker for more efficient de-stemming. The feed rate of this machine ranges from 175 lbs / hour wet and 35 lbs per hour dry.
