Older Style Hoses with Color Ties
Refer to Figure 7 and Figure 8 on page 17
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 tie.
Refer to Figure 7
To distinguish hoses on the same hydraulic circuit, refer
to hose label.
• The fan motor case drain line is a separate hose with
no label plate. This hose is always connected first and
disconnected last.
• 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.
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.
Make connections in a specific order, described on the
next page.
