towers are installed on the implement. Route the hos-
es above the cart-axle tube. Allow only enough slack
for implement to be fully raised and lowered without
binding. Use cable ties to secure hoses in a safe loca-
tion. Secure hoses to metering-box-outlet tubes using
2 1/2-inch band clamps and tighten securely. Be sure
outer clamps do not interfere with meter-box latches.
Refer to Figure 2-3.

WARNING!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Avoid the hazard by
relieving pressure before disconnecting 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, see
a doctor immediately. Any fluid injected into the skin must be
surgically removed within a few hours or gangrene will result.
Connect hydraulic hoses to rear of cart. Refer to Figure 2-
4. Working from left to right, connect hoses in the following
order.
a. Connect fold hoses to outlets on the far right (out-
lets A and B).
b. Connect lift hoses to the next set of outlets (out-
lets C and D).

Hydraulic Hose Connections
NOTE: The SAE O-ring and JIC 37˚ flare-type hose con-
nections do not require sealant for reconnecting. They do
not require high torque for a good seal.
6. Plug the lead from the electrical harness on the imple-
ment into the cart.
7. When all connections have been made, carefully
check all lines to make sure none will be damaged
when the implement is operated. Re-route the lines or
use cable ties to keep them in a safe place. Check
warning lights for correct operation.
Bleeding the Lift Hydraulics
The implement lift system is equipped with rephasing hy-
draulic cylinders that require a special procedure for bleed-
ing air from the circuit. Read and follow the procedure
carefully. The rephasing cylinders will not function properly
with air in the circuit.

WARNING!
You may be severely injured or killed by being crushed by a fall-
ing implement. Always have the frame sufficiently blocked up
when working on implement.

1. Check the hydraulic fluid level in the tractor reservoir
and fill to the proper level. Add fluid to the system as
needed while cycling new cylinders. About 5 gallons
of oil will be used to fill new cylinders. A low oil level
may draw air into the system, causing jerky or uneven
cylinder movement.
2. Jack up and support the front member of each frame
section at a point close to each gauge wheel.
3. With the frame blocked and supported, unpin the rod
end of the gauge-wheel cylinders. Pivot the cylinders
up. Wire or otherwise safely support the rod-end port
higher than the base-end port.

IMPORTANT: The cylinders located directly behind
the cart will not pivot upward for bleeding. Unpin and
remove these cylinders from the implement, then
support rod-end port higher than the base-end port.
Refer to Figure 2-5.
