SAFETY DECALS 3

Safety is a primary concern in the design and
manufacture of our products. Unfortunately, our
efforts to provide safe equipment can be wiped
out by an operator’s single careless act.
In addition to the design and configuration of
equipment, hazard control and accident preven-
tion are dependent upon the awareness, con-
cern, judgement, and proper training of person-
nel involved in the operation, transport, mainte-
nance and storage of equipment.
It has been said “The best safety device is an
informed, careful operator." We ask you to be
that kind of operator.
TRAINING
• Safety instructions are important! Read all
attachment and power unit manuals; follow all
safety rules and safety decal information.
(Replacement manuals are available at www.
riataranch.com.) Failure to follow instructions or
safety rules can result in serious injury or death.
• If you do not understand any part of this manu-
al and need assistance, contact Riata or dealer.
• Operators must be instructed in and be capa-
ble of the safe operation of the equipment, its
attachments, and all controls. Do not allow any-
one to operate this equipment without proper
instructions.
• Never allow children or untrained persons to
operate equipment.
• Train all new personnel and review instruction’s
frequently with existing workers. A person who
has not read and understood all operating and
safety instructions is not qualified to operate the
machine. An untrained operator exposes himself
and bystanders to possible serious injury or
death.
PREPARATION
• Always wear relatively tight and belted clothing to
avoid getting caught in moving parts. Wear sturdy,
rough-soled work shoes and protective equip-
ment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropri-
ate.
• Make sure attachment is properly secured,
adjusted, and in good operating condition.
• Power unit, when applicable, must be equipped
with ROPS or ROPS cab and seat belt. Keep
seat belt securely fastened. Falling off power
unit can result in death from being run over or
crushed. Keep foldable ROPS system in “locked
up” position at all times.
• A minimum 20% of tractor and equipment
weight must be on the tractor front wheels when
attachments are in transport position. Without
this weight, tractor could tip over, causing per-
sonal injury or death. The weight may be
attained with a loader, front wheel weights, bal-
last in tires or front tractor weights. Weigh the
tractor and equipment. Do not estimate.
TRANSPORTATION
• Always comply with all state and local laws
governing highway safety and lighting and
marking requirements.
• Never allow riders on power unit or attach-
ment.
• Do not operate or transport on steep slopes.
• Use extreme care and reduce ground speed
on slopes and rough terrain.
• Do not operate or transport equipment while
under the influence of alcohol or drugs. Consult
your doctor about operating this machine while
taking prescription medications.

never advisable to use powered equipment in
areas with livestock. Never operate Riata Rake in
an arena while livestock is present.
• Do not operate or transport on steep slopes.
• Do not stop, start, or change directions sud-
denly on slopes. Always operate down slopes;
never across the face.
• Use extreme care and reduce ground speed
on slopes and rough terrain.
• Keep alert and watch the front as well as the
rear when operating.
• Stop power unit and equipment immediately
upon striking an obstruction. Turn off engine,
remove key, inspect, and repair any damage
before resuming operation.
• Before leaving operator’s seat, put attachment
on the ground. Engage brake, stop engine,
remove key, and remove seat belt.
MAINTENANCE
• Always wear relatively tight and belted cloth-
ing to avoid getting caught in moving parts.
Wear sturdy, rough-soled work shoes and pro-
tective equipment for eyes, hair, hands, hear-
ing, and head; and respirator or filter mask
where appropriate.
• Never go underneath equipment (lowered to
the ground or raised) unless it is properly
blocked and secured. Never place any part of
the body underneath equipment or between
moveable parts even when the engine has
been turned off. Hydraulic system leak down,
hydraulic system failures, mechanical failures,
or movement of control levers can cause equip-
ment to drop or rotate unexpectedly and cause
severe injury or death.

ATTACH INSIDE LEVELING COMB
The inside rake has a turnbuckle which at-
taches between the leveling comb frame and
the level control arm. Raise the free end of
the top link and insert it into the clevis pin as
shown.
OPERATIONAL USE OF LEVELING COMB
You can operate the Riata Rake using a oat-
ing method or xed method of leveling. It is
recommended that the rst use of the imple-
ment you use it in a oating position with the
handle in the up position (as shown). Once
you have made a complete pass over your
arena you may wish to lock the inside leveling
comb (Down position) at a height that allows
a small amount of material to build up in front
of the comb but not in excess of a couple of
inches. This will allow Riata Rake to distribute
the footing consistently as you condition your
arena.

CONNECT RIATA RAKE TO YOUR TRACTOR’S 3
POINT HOOKUP
Now you are ready to connect your Riata Rake to the
tractor. Lower link pins are provided and are pinned in
place on your unit. Top links can vary depending on your
tractor model and size—we do not provide a top link pin.
Make sure you set the inside leveling comb adjustment
handle to the down, or locked position before you lift the
rake from the pallet.
If you are using a fork lift, attach a nylon strap to the
spine around the welded plate that connect the two
sides of the spine. This position should give a balanced
position for lifting the Riata Rake.
Warning: Do not lift Riata Rake with a forklift with the
forks under the frame. It is prone to slip off the forks due
the slick surfaces and standard length of the forks may
make this a drop hazard.
The Top Link Mast should be vertical, 90 degrees to the
arena footing. This ensures that the tine bar is level
front to back. The correct setup can be seen in gure 1

OPERATION 15

Connecting Riata Rake to Tractor
The Riata Rake is compatible with tractors equipped
with Category 1 or Category 2, 3-point hitch systems
that use side-swing type lower lift arms. The Riata
Rake will also fit tractors equipped with a Category
1 and 2 Quick Hitch ( or I Match) system.
Category 1 & 2 Standard (Figure 1)
1. Attach the tractor’s lower link arms to the Riata
Rake through the lower, inner set of holes.
2. Use the hitch pin supplied with your Riata Rake
and re-install the lynch pins.
3. Attach the tractor’s top link to the Riata Rake's
mast using a heavy-duty top link pin and lynch pin
supplied with your top link. DO NOT USE DOWN
PRESSURE/DRAFT!
4. Make sure the lower link arms are in float
position.
5. Stablizing bars should be in float position with
3-inches of sway.
1. Use Category 1 Standard instructions except
use lower, outer set of holes (*bushings required).
Category 1 Quick Hitch (Figure 2)
1. Connect the tractor’s Quick Hitch to the Riata
Rake through the upper, inner set of holes.
2. Slide lower sleeve over the mounting pin (sold
separately). Re-install lynch pins.
3. Slide upper sleeve over the heavy-duty top link
pin supplied with top link. Reinstall retaining pin.
Category 2 Quick Hitch (Figure 3)
1. Connect the tractor’s Quick Hitch to the Riata
Rake through the upper, outer set of holes.
2. Slide upper sleeve over the heavy-duty top link
pin supplied with top link. Reinstall retaining pin.
Adjusting Top Link
Adjust the three point top link so that the tine bar is
level front to rear. This will also be enabled by the
mast being in a level vertical position. In most
cases this will give the desired results. To adjust
the scarifier depth or angle of address, shorten the
three point top link. Lengthen the top link to
decrease the scarifier depth. Be sure to re level
the tine bar/Mast before using tines after ripping.
NOTE: When attaching Riata Rake to any hitch
other than a standard Category 1 hitch, bushings
and sleeves must be purchased separately.

16 OPERATION

ADJUSTING TINE DEPTH
Your Riata Rake is equipped with a tine bar array and a single adjustment point (see gure 4
below).
One way of determining the depth that is best suited for your arena is to adjust the tine bar by
extending the ratchet jack until the tines are in the footing of your arena. Now continue to adjust
the depth until you begin to see the rake frame raise off the ground—this is easy to detect if you
watch the rear comb. Now raise the tines until the rear comb is solidly in the footing material.
This position depth is the lowest possible position at that location in your arena that the tine can
be pulled. It is up to your particular sport and your footing preferences to determine the depth
for your arena footing but as a rule of thumb, 1 1/2” - 2 1/2 “ is the typical depth for most eques-
trian sports. You should not attempt this method of depth setting if your arena is a deep sand
arena.
