  • Patent number: 6148593
    Abstract: The device is a multifunctional handle for controlling an agricultural combine. The device consists of palm grip with a finger rest. Attached to the palm grip is a crescent control region. The crescent control region has an upper control area and a lower control area separated by a thumb rest area. The control areas have various controls arranged by usage. The control areas are stepped from the thumb rest area so as to allow the operator to tactilely sense the position of his right thumb relative to the control areas. The palm grip and finger rest are tapered so as to be ergonometrically comfortable for the operator's arm.
