Hydraulic Down Pressure Adjustment: (4000TM,

4800TM)

Note: This setup procedure is for tractors with closed

center pressure compensated or pressure and flow

compensating hydraulic systems. Open center

hydraulics are NOT SUPPORTED.

1) Close the rear valve (12) by turning it clockwise

until it is completely closed. Then open the valve one

complete turn.

2) Set the tractor flow rate for the hydraulic fold/unfold

system to SLOW.

3) Engage the unfold hydraulic system (continuous

flow).

4) Adjust the front valves (13)(14) to obtain 1200 psi

each.

5) Adjust the rear valve (12) to 1100 psi. Once

achieved, lock the valve using the locking disc.

6) Adjust the front valves (13)(14) to the desired down

pressure. It is recommended to adjust valve (13)

between 300-800 psi for the inner wings and adjust

valve (14) between 200-500 psi for the outer wings.

During field operation, if the wings are running too

high, increase the pressure setting on valves (13)(14)

to help level the machine. If the center of the machine

is running too high, decrease the pressure setting on

valves (13)(14).

Hydraulic Single Point Depth Stop Adjustment:

The hydraulic dept stop will ensure a consistent depth

every time the implement is lowered.

1) Prior to setting the single point depth stop, ensure

that the machine is completely level front to back and

side to side.

2) Lower the implement to the desired working depth

and pull forward. Once satisfied with the working

depth, adjust the depth stop handle to make contact

with the depth stop valve.

desired, 1 full turn of the depth stop handle either in or

out will change the depth of the machine approxi-

mately 1/4" up or down.
