A.  aMachines for harvesting citrus fruit.  c1978  aThe performance of three types of harvesting machines on Valencia oranges in discussed. The machines  were a butt shaker (J. M. Adrian peach harvester), an experimental limb shaker (Fridley Shaker), and a prototype air shaker. The direct-attachmet shaking machines proved more effective than the air shaker, with the Fridley achieving better removals than the J. M. Adrian. All machines were more effective as the mature fruit abscission force was reruced. The air harvester was the most sensitive machine to changes in fruit abscission force.  aCitrus Sinensis  aAbscission chemical  aAbscission force  aAir shaker  aButt shaker  aLimb shaker1 aHUTTON, R.
