  • Patent number: 4037666
    Abstract: Leafy and woody plants are harvested by holding the uprooted plants in a guided path while they are being removed. The uprooted and removed plants are classified and counted by a counter along the path to establish a minimum standard size to which the counter responds. The plants meeting this standard are counted until the number of the counted plants has reached a set number and the counted plants accumulate in a space between the end of the guided path and a packaging device. The counter is set to operate a forked element for moving the accumulated plants to the packaging device when the set number has been reached.
