TAKE A LOOK AROUND
DISC HOUSING
The disc housing contains (14) 22”
(559mm) hardened steel convex
discs, for long life with
superior performance.
HITCH FRAME
The unit includes an easy to mount
hitch frame, compatible with all
category II 3-Point hitches.
SWING CYLINDER (OPTIONAL)
An optional swing cylinder is
available; allowing the operator
to swing the disc housing in for
storage and transport, or out for
cutting operations.
PITCH CYLINDER
Standard equipment is a hydraulic
cylinder that controls the pitch
of the disc housing, allowing the
operator to control the angle and
depth of the cutting discs for
optimum performance.

GETTING STARTED
MOUNTING THE DISCS
Reference the tractor’s operator manual
for information on adjusting the draft
links(1) and anti-sway bars/spacers(2)(3) (if
present) on the tractor’s 3-Point hitch.
This unit requires a Catagory II hitch.
•Adjust the 3-Point hitch draft links(1)
to the fixed (non-floating) position.
◦NOTE: Draft links vary in
appearance for various
tractor models (if present).
•Replace the factory 3-Point upper
hitch link with the cylinder link(4).
•Mount the pitch cylinder(5) to the
cylinder link(4) with its hardware.
◦NOTE: Reference the parts pages
for additional clarification.
•Connect draft beams “A”(6) and “B”(7)
and the pitch cylinder(5) to the hitch
frame(8) with the QD pins and lynch
pins.
•Raise the stand(9) and secure it in
place with its pin and lynch pin.
◦NOTE: lower the stand when
removing the All American Disc
from the tractor.
•Connect the hydraulic hoses(10) to

OPERATING THE ALL AMERICAN DISC
CONTINUED ON NEXT PAGE
Before you operate, note that the primary responsibility for safety on this
equipment falls to the operator. Only trained individuals who have read and
understood this manual should operate this unit.
If any portion of this manual is not understood, contact:
Diamond Mowers’ Service/Warranty at 888.960.0364 or 605.977.3300.
Be sure to read all warnings carefully. They are included for your safety,
and for the safety of others working with you.
SAFETY TIPS
Indicates where SERIOUS injury or death WILL result if instructions
are not followed.
Indicates where SERIOUS injury or death COULD result if instructions
are not followed.
Indicates where MINOR injury COULD result if instructions are
not followed.
Indicates a property damage hazard ONLY, no PERSONAL injury.
•Always wear personal protective equipment (safety glasses, goggles,
etc.), when operating.
•Operate only from the operator’s station.
•Clear the work area of obstructions and safety hazards.
•Bystanders must keep a distance of 300ft/100m from the unit
when operating.
•Discs are always sharp and can cause injury, even when not
in motion.
•DO NOT use extremities to dislodge debris from the cutting discs.
10

•Hydraulic fluid is hot and will heat any exposed steel, hoses, motor, or
spindle in its proximity.
•Make certain hoses are out of the way and will not snag on vegetation
and debris.
•Be certain to come to a complete stop and all motion is ceased before
exiting the cab.
When transporting Diamond’s All
American Disc between operations,
make sure to protect it from collisions
and accidental damages by placing it in
the stowed position.
Failure to place the head in its stowed
position could result in
structural damage.
STOWED POSITION
•EXTREME CAUTION should be used
when operating on slopes(1) greater
than 25°(2). It is the operator’s
responsibility to properly counter-
balance the vehicle and machine to
prevent rollover.
Contact with the cutting discs while the All American Disc is in
operation can result in serious injury or death.

OPERATING THE ALL AMERICAN DISC
DISCING
CONTINUED ON NEXT PAGE
Use to reclaim road shoulder material.
•Start the tractor and raise the engine RPM’s to operating speed.
•Extend the optional swing cylinder (if present) until the disc housing(1) is
at full extension(2).
•Use the pitch cylinder to adjust the pitch(3) of the cutting discs.
◦The pitch of the cutting discs should allow the rearmost disc to enter
the soil before the lead disc when the discs are lowered into the soil.
◦DO NOT exceed a maximum of 15° difference in height between the
rearmost and lead cutting disc.
•Lower the cutting discs into the ground, but do not exceed 1” (25mm)
cut depth.
◦DO NOT cut sod with the lead blade! This indicates either there is
not enough pitch or the cutting depth is too deep, and will result
in peeling large clumps of sod; this is undesireable. Cutting is
accomplished with the other blades.
-Adjust your pitch as needed to prevent cutting with the lead disc.
(2)

12

•Begin discing the road shoulder at a steady pace (10MPH/16KMH)
maximum for gravel roads, less for hard surfaced roads.
◦Keeping the speed even and constant will allow the cutting discs to
feather the material evenly.
-It is recommended to allow the material to dry for a minimum of
two to three days, longer if there is precipitation, before discing.
Dry material grades easier than wet material.
-A roller will help on hard surfaced road shoulders. It is suggested
to disc, roll, grade, and then do a final roll for best results on hard
surfaced road shoulders.
-Always grade after the first pass of the discs.
DO NOT make multiple passes of the cutting discs and then
attempt to grade; there will be too much material to grade
effectively.
For more tips, visit us online at www.DiamondMowers.com
Lowering the cutting discs too deep into the soil can damage the road
shoulder, and can cause damage to the cutting discs, housing, and
hitch frame.
