Abstract
A hand control system for a tractor having several controllable units such as hydraulic and brake units. A tubular member is rotatably mounted about its longitudinal axis and it connects to one of the units for actuating the same, and a member is pivotally mounted on the tubular member and has a handle thereon which connects to a linkage extending partly through the tubular member and connects to another of the units for operating same. The tubular member can be rotated to actuate its connected unit, without requiring actuation of the handle, and, conversely, the handle can be actuated to move its linkage and actuate its connected unit, without moving the tubular member and its unit. Also, another tractor unit, such as a brake, is connected into the system such that when the one member is pivoted upwardly on the tubular member the handle is placed in an inoperative position and the brake is automatically operated, as desired.
