The packer fork drive (20) is an epicyclic drive with a first arm (224) secured to a driven first shaft (214) and a second arm (248) rotatably secured to a second shaft (234) on the free end of the second arm (248). A chain (256) is trained around a stationary sprocket (250) concentric with the first shaft (214) and a second sprocket (254) concentric with the second shaft (234) and secured to the second arm (248). A packer fork assembly (18) is connected to the free end of the second arm (248). |
