identical. Location and layout of the port bulkheads are
different. Both are to the left side of cart rear frame.

!

WARNING

Escaping fluid under pressure can penetrate skin, causing seri-
ous injury. Avoid the hazard by relieving pressure before dis-
connecting hydraulic lines. Use a piece of paper or cardboard,
NOT BODY PARTS, to check for leaks. Wear protective gloves
and safety glasses or goggles when working with hydraulic
systems. If an accident occurs, seek immediate medical atten-
tion from a physician familiar with this type of injury.

Refer to Figure 22

To distinguish hoses on the same hydraulic circuit, refer
to plastic hose label. The hose under an extended-cylin-
der symbol feeds a cylinder base end. The hose under a
retracted-cylinder symbol feeds a cylinder rod end.

IMPORTANT !

DO NOT connect return line to a power-beyond-port.

The drill has two or three hydraulic circuits (with a low
pressure sump return line). The standard circuits power
lift, fold and weight-transfer functions. An optional circuit
operates the markers.

16. Remove male fittings from hydraulic quick couplers

on the rear of the cart. Screw the male ends onto the
implement hydraulic hoses.

IMPORTANT !

If you will not be installing markers, store the male QD
fittings with the drill for future use. Do not leave them in
the QD ports or oil will spill.

17. Shut down tractor hydraulics.

18. Connect either (orange) Marker hose to receptacles

and

in any order.

20. Connect the Retract/rod-end hose of the (yellow)

Fold pair to receptacle

. Connect the Extend/base-

end hose of the (yellow) Unfold pair to receptacle

.

21. Connect the sump hose to receptacle

22. Check hose routing to ensure adequate slack for link

arm movement, and clearance from pinching or
abrading cart/drill components.
