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 6
Hydraulic hoses are color coded to help you hookup
hoses to your tractor outlets. Hoses that go to the same
remote valve have coded ties with the same color.
Refer to Figure 6
To distinguish hoses on the same hydraulic circuit, refer
to the cylinder symbols on the clamps.
• The hose under an extended-cylinder symbol feeds a
cylinder base end or motor return line.
• The hose under a retracted-cylinder symbol feeds a
cylinder rod end, or motor pressure line.
Low Population Risk:
If the motor hose connections are reversed (relative to
operator expectations), the motor runs in reverse, but at a
speed and air flow too low for correct seed metering.
Secure hoses and cables so that they have sufficient
slack for hitch movements, but cannot get caught
between moving parts of planter. Failure to safely route
and secure hoses and cables could result in damage
requiring component repair/replacement, and lost field
time.
