Hydraulic Hose Hookup
High Pressure Fluid Hazard:
Shut down tractor before making hydraulic connections.
Only trained personnel should work with system hydraulics.
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. If an accident
occurs, seek immediate medical assistance from a physician
familiar with this type of injury.
Use paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems.
Refer to Figure 8
On implements with more than one hydraulic circuit,
hydraulic hoses are color coded to help you hookup
hoses to your tractor outlets. Hoses that go to the same
remote valve are marked with the same color.
To distinguish hoses on the same hydraulic circuit, refer
to hose label.
• The hose under an extended-cylinder symbol feeds a
cylinder base end, or the return side of a hydraulic
motor.
• The hose under a retracted-cylinder symbol feeds a
cylinder rod end, or the pressure side of a hydraulic
motor.
Use a regular remote and not a dedicated tractor 3-point
remote
a
Secure hoses and cables so that they have sufficient
slack for hitch movements, but cannot get caught
between moving parts of fertilizer applicator. Failure to
safely route and secure hoses and cables could result in
damage requiring component repair/replacement, and
lost field time.

a. Some tractors provide a special remote pair at the 3-point hitch arms. On some tractor models, this circuit has specific flow and/or
pressure-sensing behavior intended for certain implements (other than Nutri-Pro ® ). Nutri-Pro ® lift and/or fold and weight transfer may
not function on this type of circuit.
Machine Function Risk:
The NP4000 weight transfer system requires a tractor with
closed center hydraulics. Open center hydraulics are
incompatible.
