THEORY OF OPERATION - CONTINUED
FRAME, TOWING ATTACHMENTS, DRAWBARS, AND ARTICULATION SYSTEM - CONTINUED
Articulation System. The front frame section and the frame and case (rear frame section) are joined (hinged) at their
hitch bushings. Two hydraulic articulation cylinders and lines provide power for articulation. They are controlled from
the cab. One cylinder is mounted at each side of the front frame section and extends to attach to the rear frame section to
provide articulation control.
Articulation Indicator. Indicator is mounted inside the cab at the top of the steering console. A small housed cable
mounted on the front frame is attached to a lever fastened to the rear frame. When the frame is articulated, the cable
moves the pointer on the indicator to show the amount of articulation.
