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.
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 the cylinder symbols on the hose handles
a
.
• The hose with an extended-cylinder symbol feeds a
cylinder base end, or the return side of a hydraulic
motor.
• The hose with a retracted-cylinder symbol feeds a
cylinder rod end, or the pressure side of a hydraulic
motor.
On a 2-point
b
implement, connect either hose to either
side of the remote. Use a regular remote and not a
dedicated tractor 3-point remote
c
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. Older implements do not have handles. The cylinder symbols are instead on a hose label clamped near the QD connectors.
b. The 2-Point implement has a merged hydraulic circuit in which different cylinders are extending and retracting at the same time, and thus
cannot meaningfully use the hose label. Determine by testing which lever direction lifts/folds and lowers/unfolds.
c. Some tractors provide a special remote pair at the 3-point hitch arms. On some tractor models, this circuit has specific flow and/or pres-
sure-sensing behavior intended for certain implements (other than Nutri-Pro
®
). Nutri-Pro
®
lift and/or fold may not function on this type of
circuit.
Machine Function Risk:
The NP30/40L weight transfer system requires a tractor with
closed center hydraulics. Open center hydraulics are
incompatible.
