Maintenance
2. Stop the tractor engine, apply the tractor parking
brake, and take the key with you.
3. Apply the parking brake on the drill.
4. Locate the button for the shunt valve (2) on the
left-hand side of the machine near the ladder (3).
Push the button all the way in to empty the air
reservoir. This will release the air from the air
brake system.
5. Carefully remove the retainer ring (4) from the
housing. Components are under spring pressure.
Be careful not to lose any of the components.
Individual parts are not available.
6. Remove the cap (5) and O-ring (6).
7. Remove the outer spring (7).
8. Remove the brass washer (8).
9. Remove the screen (9).
10. Remove the inner spring (10).
11. Using gentle compressed air, or a soft brush and
compatible cleaning fluid, remove debris from the
screen. Dry thoroughly.
12. Wipe the inside of the housing with a clean
lint-free cloth.
13. The cap is a debris sump. Clean with air, or water
and mild detergent. Dry the cap if wet. Inspect
the O-ring and replace as necessary.
14. Install the inner (light) spring in the housing.
15. Install the screen in the housing closed-end first.
16. Install the brass collar with the flange away from
the filter.

Cart Brake Maintenance
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.
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).
Check brakes for wear, contamination and damage
seasonally or every 9600 km.
Review the entire procedure. Great Plains suggests
performing a complete operation on one wheel at a
time, so that there is a fully-assembled wheel to use
as an assembly reference.
1. Park the drill on a solid, level surface. Unfold and
lower the drill. Stop the tractor engine and take
the key with you.
2. Chock both cart tires, both caster wheels, and
both gauge wheels to prevent movement.
3. Put the tractor transmission in park. Release
tractor service brake and tractor parking brake.
a. If the drill has hydraulic brakes:
Rotate the shaft in the emergency valve (1) to
release the pressure in the accumulator (2).
Releasing the pressure in the accumulator
releases the brakes.
