Abstract: A winch drum drive system for controlling a kite. The winch drum drive system includes spools for winding an unwinding kite control lines and a set of planetary gears rotatably attached to one end of each of the spools. A ring gear wraps around each set of planetary gears so that the internal perimeter of the ring gear is meshed with each of the planetary gears in the set. The ring gear includes a set of external teeth so that it may be meshed with a second ring gear corresponding to a different spool. A ring drive gear is meshed with one of the ring gears, so that when power is sent to the ring drive gear the ring gears rotate in different directions. A sun gear is positioned between and meshed with each set of planetary gears. A sun drive gear is placed between and meshed with the sun gears so that when power is sent to the sun drive gear, the sun gears rotate in the same direction.

Abstract: A method and apparatus are provided for felling and chipping trees, all on a single vehicle, including mounting a grapple and a shear on a connector, mounting the connector to a boom, engaging a tree with the grapple and shear, shearing the tree, moving the tree to a table, moving the vehicle forward to feed the tree on the table into a chipper, feeding the chips from the chipper, into a bin, and empty the bin by tilting same.
