Shaker injuries to the bark of trees can be minimized by careful operation of properly designed equipment. One careful grower, Andrew Micke of Tehama County, has been harvesting prunes with a commercial shaker for five years with no indication of serious damage. He has lost a few limbs but no trees. He was probably the first person to mechanically shake prunes with a tractor shaker, according to extension service records.
