DEFINITION

Classification: 172/663

(under the class definition) Apparatus comprising an actuator for adjusting some part of the apparatus.

(1) Note. See the class definition for the definition of

"actuator".

(2) Note. A latch or lock operator which does not adjust some part of the apparatus is not included under this definition.

2+, for power actuators which are automatically controlled.

224+, for actuators for implements rotatable about a longitudinal axis for right or left hand operation. 263, for an actuator which is released when an earth working element shifts due to an overload.

278+, for an actuator for changing the horizontal angle of the axis of rotation of a wheel.

293+, for power-actuating means for sequentially operating a plurality of like implement parts.

297+, for an actuator to adjust an implement mounted forward of the rear of a self-propelled vehicle.

315+, for an actuator on an implement which is controlled from a propelling vehicle.

317+, for an actuator on a vehicle for relatively moving parts of a trailing implement.

321, for an actuator on a vehicle for moving a wheeled implement.

322, for an actuator for rocking an implement about a wheel axis.

324+, for an actuator for moving a draft member laterally or vertically on a wheeled frame.

395+, for an actuator for vertically adjusting a wheel relative to a frame.

439+, for mast-type hitches (e.g., 3 point hitch) with actuating means to adjust the hitch.

452+, for an actuator for raising and lowering an implement on a wheeled frame and being capable of lifting the implement out of ground contact for transport. 613+, an actuator for changing the position of a plurality of relatively movable tools.

781+, for an actuator for moving a scraper mounted between the front and rear ground supports of a vehicle.

810+, for an actuator to move an implement mounted ahead of a

motor vehicle.
