Explanation
Early production YP Planters and Air Drills were not manufactured with fan motors that utuilized a
case drain connection. If there are only two lines connected to the fan motor , then the case drain
connection is not utilized. If there are three hoses connected to the fan motor , then case drain is
utilized.
The purpose of this guide is to show the port locations for connecting case drain and motor return
for Great Plains YP Planters and Air Drills that utilize continuous flow fan motors. The information
obtained for this guide was taken directly from the tractor manufacturer’s information that is
available on-line and through tractor dealers.
Since tractor equipment and options vary , the connections shown in
this guide must be verified through the tractor manufacturer or dealer
to prevent damage to the tractor and implement hydraulic systems.
Great Plains continuous flow fan motors require case drain and motor return lines to protect
the motor during use. The case drain line must be connected first, then connect motor return
line before connecting the pressure line. Failure to do so can cause damage to the motor
seals. When disconnecting, always disconnect pressure, then motor return, and case drain
last.
ALWAYS Connect ALWAYS Disconnect
Case Drain First Fan Pressure First
Motor Return Second Motor Return Second
Fan Pressure Last Case Drain Last
Case Drain
This connection is required to carry the motor case internal leakage directly to the
tractor hydraulic reservoir (sump) with zero pressure. This oil serves to lubricate and
cool motor components not directly exposed to the working oil. Great Plains supplies a
3/8” body size ISO 16028 zero pressure flat face case drain male coupler on a 1/4”
hydraulic hose for the fan case drain line. It is normal to have seepage from this fitting
when disconnected from the tractor to protect the motor seals from thermal expansion.
If the tractor is not equipped with a female flat face case drain coupler , then it must be
sourced through a tractor dealer or hydraulic supplier.

Motor Return
This connection is required to carry the low pressure return oil from the motor to the
hydraulic reservoir or charge circuit. Using a motor return port prevents accidental
reverse operation and possible flow checking of the return SCV coupling. Great Plains
supplies a 3/4” body size ISO 7241-1 Series A male and female coupler with each
YP planter and air drill. The male coupler is installed on the 1/2” or 5/8” motor return
hydraulic hose from the factory. The mating female coupler must be connected to the
tractor motor return port. The motor return hose and couplers are large to reduce back
pressure to the motor.

Tractor Requirements
Tractors connected to Y P Planters and Air Drills must meet the following requirements:
1. LS Closed or PC Closed hydraulic systems with a case drain
connection and a motor return connection. Open Center
hydraulic systems
MUST NOT be used.
2. Verify the tractor Hp meets the requirements listed in the
Specification section of the planter or drill Operator’s Manual
before connecting.
Tractors Equipped with Additional Accessories Connected
to Case Drain and/or Motor Return
Some tractors may be equipped with additional accessories that connect to power beyond
connections on the rear of the tractor (i.e. auto steering). If the case drain and motor return
connections are already in use, then tee’s can be installed to add connections.
IMPORTANT!
DO NOT tee case drain into motor return. Case drain must have zero pressure return. Great
Plains warranty will be voided if case drain has been connected and/or teed to a motor
return line. Case drain should only be returned directly to the hydraulic reservoir. The case
drain line must utilize an ISO 16028 coupler that will allow seepage due to thermal expansion
when disconnected from the tractor.
If tractor case drain circuit is filtered, it is necessary to make sure to have a clean filter to
prevent excessive case pressure. High case pressure will cause motor seal failure.
DO NOT connect the fan motor to power beyond pressure. Continuous flow through the
power beyond will deprive the tractor rear differential and pto drive gears of hydraulic flow
and cause damage to the tractor.
Some tractor manufacturer’s have chosen to use the same type coupler for power beyond
load sense lines as for case drain lines. It is very important that these not be confused to
prevent motor seal damage. DO NOT connect the case drain hose to a power beyond load
sense coupler.
Some tractor manufacturer’s recommend running motor return through a tractor SCV return
port. DO NOT run motor return through a tractor SCV return port. Minimum pressure on
most tractor SCV return ports is approximately 250 to 300 psi. Only connect motor return to
a motor return port. Motor return ports allow pressures less than 50 psi, which prolongs
motor seal life.
Failure to use the correct motor return port can cause oil starvation to the transmission
pump and hydraulic charge circuit on some tractors. This is caused when oil is returned into
the differential housing rather than the transmission or hydraulic charge circuit.
Make sure all hydraulic couplers and hose ends are clean before connecting.

The motor return and case drain ports are
capped with DIN (Deutsch Institute Normung)
sized fittings from the factory . It is necessary to
convert the motor return fitting to 1-1/16 MORB
to use the female o-ring motor return coupler
supplied with Great Plains planters and air drills.
The case drain must be converted to 3/4-16
MORB.
Tractors manufactured later than s/n P146047
will have a loadsensing decompression tube
installed between the load sense and case drain
ports. The decompression tube can be removed
if port access is needed. Removal of the
decompression tube leaves a small risk that the
hydraulic circuit could hold residual loadsensing
oil pressure.
IMPORTANT: ALWAYS connect case drain

prevent motor damage. ALWAYS disconnect
pressure line first, motor return second, then
case drain last to prevent motor damage.

Determining Type of Fittings Needed for
8600 Series / DTB Series / MT600C Series
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.
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.
