Hydraulics
High Pressure Fluid Hazard
Escaping fluid under pressure can have
sufficient pressure to penetrate the skin
causing serious injury. Check all hydraulic
lines and fittings before applying pressure.
Use paper or cardboard, not body parts,
and wear heavy gloves to check for
suspected leaks. If injured, seed immediate
medical attention from a physician familiar
with this type of injury.
High Pressure Fluid Hazard
Do not attempt to make hydraulic system
repairs. Great Plains strongly recommends
that all hydraulic system repairs to be
completed by a trained professional who is
knowledgeable about how to safely complete
hydraulic system work. You should only
maintain or adjust your hydraulic system as
described within this manual. Compromising a
closed hydraulic system can cause serious
injury or death.
Contamination is the most common cause of
performance problems and premature wear with
hydraulic systems. Make sure to properly clean quick
couplers before attaching the hoses to the tractor.
Never let the hoses fall on the ground.
In-Line Hydraulic Filter
If folding/unfolding time slows noticeably, check the
in-line hydraulic filter and clean if needed. The
hydraulic filter is located at the inlet port of each
pressure valve.
1. Move the drill to typical field conditions. Unfold
the drill. Lower the openers. Turn on the fan and
bring up to normal field rpm.
2. Set fold circuit to float.
3. Shut down the tractor and remove the key.
4. Slowly loosen the hydraulic filter and relieve any
residual pressure in the line. When disconnecting
the hose, support the end to minimize fluid loss.
5. To disassemble, unscrew the end cap of the
hydraulic filter. Remove the top retaining washer
and screen.
6. Clean the filter screen with solvent and
compressed air, or replace if needed.
7. When reassembling put the screen into the
hydraulic filter. Place the retaining washer on top
of the hydraulic filter and screw on the end cap.
8. Install the hydraulic filter.
9. Activate the fold circuit. Cycle the lift and fold
systems several times. Check for leaks.

Brakes
Possible Asbestos Hazard
If you are unable to confirm that you are
removing and installing ADR approved
parts, you may have linings that contain
asbestos. Some after - market brake shoes
may contain asbestos, and require strict,
complex and costly safety procedures not
covered in this manual.
Equipment Malfunction Risks
If brake shoe replacement is indicated, use
only parts supplied or recommended by
ADR. Unapproved parts may appear to fit,
but will not function correctly.
Check brakes for wear, contamination and damage
seasonally or every 9600 km.
Inspecting the brakes may show a need to refinish
the drums and/or replace other brake parts. Although
not strictly part of brake maintenance, you may need
to repack the bearings (generally the outer), and it
may be necessary to replace a worn or damaged
inner seal and pack the inner bearing with fresh
grease.
For service of internal brake components, refer to
ADR parts and service information.

Air Brake Reservoir Draining
Before storage, or daily in humid operations, drain
water from the air reservoir tank (1). Draining the air
reservoir can prevent rust inside the tank and rust
contamination of the brake valve system.
1. Chock the cart tires.
