Abstract: On March 21, 2005, Employee #1, of P & R Brar Farms, was applying an herbicidal spray in the facility's vineyard. He was operating a Landini type PPHL/BA agricultural tractor, pulling the spraying machinery mounted on a trailer. The spraying mechanism is activated when one end of a rope attached to a lever on the trailer is pulled by the operator. The rope being used was sisal twine with a diameter of approximately 0.19 in. Slack in the twine between the tractor and the trailer had caused a loop to form in the line. The loop became entangled around the tractor's rear tire and suddenly pulled the twine taut, catching Employee #1's left hand between the two components and amputating three fingers. He was hospitalized.
