These tractor models may or may not be
equipped with case drain and motor return lines
from the factory. The part numbers given for
these models is assuming the lines are
installed. Contact an AGCO dealer if the lines
are not installed.
IMPORTANT: The coupler called out in the
AGCO parts books for the case drain
connection is NOT compatible and must be
changed.
AGCO calls for using a standard 1/2” male
coupler for the case drain which is not
compatible. Case drain requires a 3/8” body
size ISO 16028 zero pressure female flat face
coupler.
Determining Type of Fittings Needed for
8600 Series / DTB Series / MT600C Series
The coupler supplied through AGCO for motor
return is compatible and can be used. However,
the coupler is male, therefor the male coupler
on the motor return line on the planter or drill
must be removed and install a female coupler
in its place.
There are two different types of fittings used
on these models of tractors. The difference is
in the type of caps on the bulkhead fittings. One
type is ORFS (one piece), the other type is DIN.
Determine which type of caps are on the tractor
and use the correct diagram and parts listing
on the following page to install adaptor fittings
for the case drain coupler.
