Site preparation and circumstances
– Evaluate the terrain to determine what
accessories and attachments are needed to
properly and safely perform the job. Only use
accessories and attachments approved by the
manufacturer.
– Clear the area to be aerated of objects such
as rocks, toys, wire or other debris that may be
picked up or thrown by the machine.
– Be sure the area is clear of pets and people,
especially young children. Never assume they
will remain where you last saw them. Stop the
machine if any enter the area.
– Operate only in daylight or in good articial light.
– Do not operate on wet grass as tires may lose
traction.

SAFETY
OPERATING SAFELY
IN GENERAL
– Use extra care when loading or unloading the
machine onto a trailer or truck. Do not use split
ramps. Use full width ramps to load or unload
unit.
– Watch out for trafc when near or crossing
roadways.
– Do not run the engine in an enclosed area where
dangerous carbon monoxide fumes can collect.
– Do not place your foot on the ground while
operating the machine with the platform down.
– Do not pull any loads or equipment.
– Never leave a machine unattended. Always set
parking brake, stop engine and remove keys
before dismounting.
MACHINE PREPARATION
– Check operator present interlock system and
brake operation. Adjust or repair any problems
before using.
– Do not tamper with or defeat safety devices.
Keep guards, shields and interlock safety devices
in place and in proper working condition. They
are for your protection.
– Keep all fasteners such as nuts, bolts and pins
well secured.
– Visually inspect tines, tine bolts and the aerating
assembly for wear or damage. Replace worn or
damaged tines and bolts.
– Verify that machine and attachments, if any, are
in good operating condition.
– Do not lower tines until ready to aerate.
STARTING
– Start only according to instructions in this manual
or on the machine.
– Before attempting to start the engine, make sure:
- the parking brake is on;
- the traction drive is in NEUTRAL.
– When starting the engine, make sure hands and
feet are clear of the tines.
– Do not change engine governor settings or
overspeed the engine. Operating the engine
at excessive speed can increase the hazard of
personal injury.
MANEUVERING SAFELY
IN GENERAL
– Slow down before turning.
– Do not aerate in reverse unless absolutely
necessary. Always look behind and down
for small children and pets before and during
backing.
– Be aware when approaching blind corners,
shrubs, trees, tall grass or other objects that may
obscure vision.
WALK-BEHIND USE
– The aerator may be operated as a walk behind
unit by raising the footplate and latching it in the
stowed position. Walk behind mode is useful
when terrain or circumstances make operation as
a ride-on uncomfortable or even dangerous. For
example operation near a bank, above a drop-off
or retaining wall would be places where walk-
behind mode should be used. When operating
as a walk-behind, operate across slopes, not up
and down.

5
SA-30 SAFETY
INTERRUPTING OPERATION
– Before leaving the operator's position:
- Park on level ground;
- Set the parking brake;
- Shut off the engine and remove the key.
– Stop the engine:
- before refueling;
- before making adjustment unless the
adjustment can be made from the operator's
position.
– Stop the engine and disconnect the spark plug
wire(s) or remove the key:
- before clearing blockages;
- before checking, cleaning or working on the
machine;
- after striking a foreign object. Inspect the
machine for damage and make repairs before
restarting.
- if the machine begins to vibrate abnormally:
Inspect and make repairs as needed before
restarting;
- except for repairs or adjustments as
specically noted, such as for carburetor
adjustment, where the engine must be running.
Keep hands and feet clear of moving parts in
these circumstances.
– Reduce the throttle setting during engine shut-
down and, if the engine is provided with a shut-
off valve, turn the fuel off at the conclusion of
aeration.
AERATING SLOPES
Slopes are a major factor in loss-
of-control and tip over accidents
that sometimes lead to severe
injury or death. All slopes require
extra caution.
– Before operating on slopes evaluate the risks
involved.
– Do not operate on slopes if uneasy or uncertain.
Ultimate responsibility for safe operation on
slopes rests with the operator.
– Do not aerate steep slopes:
Slope is too steep if:
- the machine must be crabbed (turned partially
sideways uphill) to drive across the slope.
- The machine turns downhill going across the
slope.
-You are uneasy about being on the slop.
– With ride-on machines, including articulated
steering machines, operate up and down slopes,
not across, except for zero turn machines. Zero
turn machines should operate across slopes.
– With walk-behind machines, always operate
across slopes, not up and down.
– Avoid starting or stopping on a slope. If tires lose
traction, disengage the tines and proceed slowly
straight down the slope.
– With a zero turn machine, if tires lose traction
going down a slope, steering control may be
regained by speeding up.
– Zero turn machines have much greater traction
pointed up slope than down slope. Be aware that
traction may be lost going down a slope. Do not
operate a zero turn machine on slopes it cannot
back up.
– Keep all movement on the slopes slow and
gradual. Do not make sudden changes in speed
or direction.
– Do not turn on slopes unless necessary, and then
turn slowly and downhill when possible.
– Stay away from slopes if the ground is loose or if
caught in the rain during aeration.
– Use lower speeds on a slope to avoid stopping or
shifting.
– Use extra care with attachments. These can
change the stability of the machine.
– Avoid driving over ruts, holes, rocks and roots
whenever possible. Be alert to dips and rises.
Uneven terrain can overturn a machine or cause it
to slide.
– Do not aerate dropoffs, ditches or embankments.
The machine could suddenly turn over if a wheel
runs over the edge or an edge caves in.
– Follow the manufacturer's recommendations
for wheel weights or counterweights to improve
stability.

MAINTENANCE SAFETY
IN GENERAL
– Maintain machine according to manufacturer's
schedule and instructions for maximum safety
and best results.
– Park machine on level ground.
– Never allow untrained personnel to service ma-
chine.
– Adjust or repair only after the engine has been
stopped and the tines have stopped rotating.
– Guards should only be removed by a qualied
technician for maintenance or service. Replace
when work is complete.
– Replace parts if worn, damaged or faulty.
For best results, always replace with parts
recommended by the manufacturer.
– Disconnect battery or remove spark plug wire(s)
before making any repairs. Disconnect the nega-
tive terminal rst and the positive last. Reconnect
positive rst and negative last.
– Do not dismantle the machine without releasing
or restraining forces which may cause parts to
move suddenly.
– Provide adequate support for lifted machine or
parts if working beneath.
– Do not put hands or feet near or under rotating
parts.
– Clean up oil or fuel spillage thoroughly.
– Replace faulty mufers.
– To reduce re hazards, keep the engine, mufer,
battery compartment and fuel storage area free
of grass, leaves, debris buildup or grease.
Tines
– Tines are sharp and can
cut. Use extra caution when
handling. Wear appropriate
personal protective equip-
ment.
WARNING
FUEL
– Gasoline and diesel fuels are
ammable; gasoline vapors
are explosive. Use extra
care when handling.
– Store only in containers spe-
cically designed for fuel.
– When refueling or checking fuel level:
- Stop the engine and allow to cool;
- Do not smoke;
- Refuel outdoors only;
- Use a funnel;
- Do not overll;
- If fuel is spilled, do not attempt to start the
engine until the spill is cleaned up and vapors
have cleared.
Sparks from static electricity can start res or cause
explosions. Flowing fuel can generate static
electricity. To prevent static electricity sparks:
- Keep fuel containers electrically grounded.
– Do not ll containers in a vehicle or on a truck or
trailer bed with a plastic liner. Fill containers on
the ground away from the vehicle.
– When practical, remove gas powered equip-
ment from the truck or trailer and refuel it on the
ground. If equipment must be refueled on the
truck or trailer, refuel from a portable container
rather than a dispenser nozzle.
– Keep the dispenser nozzle in contact with the rim
of the fuel tank or container opening until fuel-
ing is complete. Do not use a nozzle lock-open
device
– Replace caps on fuel cans and tanks securely.

interlock system each time you operate the
unit.
PRE-OPERATION CHECK LIST
SERIOUS INJURY OR DEATH MAY RESULT
FROM MACHINE ROLLOVER
• DO NOT OPERATE MACHINE ON STEEP
SLOPES OR NEAR DROPOFFS
• AVOID SHARP AND/OR QUICK TURNS
ROLLOVER MAY CAUSE PERMANENT INJURY OR DEATH.
• SUDDEN STARTS OR TURNS ON RAMPS OR SLOPES CAN CAUSE OVERTURN.
• USE GREATER CARE ON RAMPS AND AS THE SLOPE INCREASES.
Use caution when making turns. Slow down before making sharp turns to help maintain control and to
prevent torn turf from skidding or spinning tires. To help prevent turf damage, keep both drive tires moving
whenever a turn is made.
TIP: The best way to make a sharp "zero" turn is to come to a stop, get the machine moving in reverse with
both drive wheels and then powering the machine around with the outside wheel. This technique keeps the
drive tires turning and results in less turf damage.

SA-30 OPERATION
FUELING
– Fill fuel tank(s) with good quality, clean, unleaded
gasoline. Do not use hi-test fuel. Do not use fuel
with more than 10% ethanol (E10).
– Use a funnel to avoid spillage.
WARNING
TO CHECK OR ADD FUEL:
– Do it outdoors
– Do not smoke
– Stop engine; allow to cool
– Fill to one inch below bottom
of ller neck
– Do not overll
– Clean up spilled fuel
BEFORE STARTING THE ENGINE
– Be familiar with all controls, how each functions
and what each operates.
– Check the engine oil level and add if necessary.
Turn fuel valve to ON.
– Choke: For cold starts, set the throttle lever to
the half-open position and pull the choke out to
the ON position. For warm starts set the throttle
to the half-open position and the choke to the OFF
position.
OPERATOR PRESENCE
INTERLOCK SYSTEM
To start the engine:
–The left hand operator presence control lever
must be in the neutral position.
–The parking brake must be ON.
To operate the machine:
1. The operator must release the parking brake
before holding the operator presence control lever
down or the engine will kill.
STARTING THE ENGINE
1. Lower the operator platform and stand on it.
2. Turn the key to operate the electric starter to start
the engine. Release the key when the engine
starts.
3. If the engine does not start immediately, do not
crank for more than 10 seconds at a time. Allow
60 seconds for the starter motor to cool down
between starting attempts to prevent the starter
motor from burning out.
4. If the choke is ON when the engine starts, gradu-
ally back it off until the engine runs with no choke
at all.
DRIVING
1. Move the parking brake to OFF position.
2. Move traction control lever out of neutral.
3. Push both traction levers forward evenly to drive
forward in a straight line. Pull both traction levers
back evenly to drive backward in a straight line.
OPERATING NOTES
– Practice at slow engine and travel speeds with the tines up until fully familiar with the controls.
– For normal aeration, the throttle should be set at the full open position. By using the traction levers to
speed up or slow down the machine during use, maximum control and aeration efciency can be main-
tained.
– Using the machine at less than full throttle in heavy conditions will cause the engine and hydrostats to
labor and result in excessive wear to the engine and hydraulic system.
– The aerator may be operated as a walk behind unit by raising the footplate and latching it in the stowed
position. Walk behind mode is useful when terrain or circumstances make operation as a ride-on
uncomfortable or even dangerous. For example operation near a bank, above a drop-off or retain-
ing wall would be places where walk-behind mode should be used. When operating as a walk-
behind, operate across slopes, not up and down.

Turns during reverse movement:
–Reverse right turn -
move the right traction
lever forward toward
neutral to slow the right
drive wheel.
–Reverse left turn -
move the left traction
lever forward toward
neutral to slow the left
drive wheel.
Slow, sweeping turns are made with both traction
levers on the same side of neutral and slightly
apart. True zero radius turns about the center of the
machine are made by having one lever in reverse
while the other is in forward. By varying the relative
positions of the two levers, the rate of turn is varied to
suit the situation.
Slow down before making sharp turns. The machine
is capable of turning very rapidly when the levers are
moved further apart from each other. Loss of control
and/or turf damage may result.
STOPPING
1. Raise tines.
2. Release control traction levers or move to neutral.
3. Engage the parking brake.
4. Turn key to OFF (counterclockwise).
STEERING
Forward movement - To
move the machine straight
ahead, push both control
levers forward equally
from their neutral posi-
tion. Increase speed: as the levers are moved
farther forward from the neutral position. Decrease
speed: when traveling forward, pulling the traction
levers rearward slows the machine. Stopping: The
machine will stop when the levers reach the neutral
position.
Reverse movement - To
move the machine straight
back, pull both traction
levers back equally from
their neutral position. Re-
verse speed increases as the levers are moved back
farther. Maximum reverse speed is reached when the
levers stop. When moving in reverse, pushing the
levers forward slows the machine, and the machine
stops when the neutral position is reached.
NOTE: The control levers are spring loaded to return
to neutral in both forward and reverse. This spring
resistance may be felt when moving the traction le-
vers. When control levers are released, spring ten-
sion will quickly return them to the neutral position.
To turn, move one lever forward and one back.
Turns during forward movement:
–Forward Right turn
- move the right trac-
tion lever back toward
neutral to slow the right
drive wheel.
–Forward Left turn
- move the left traction
lever back toward neu-
tral to slow the left drive
wheel.

SA-30 OPERATION
AERATING
NOTE: For best performance, the lawn to be aerated
should be thoroughly watered the day before.
1. Drive machine to the site to be aerated.
2. Set the tine depth stops to the desired aeration
depth.
3. Lower the tines by rocking the raise-lower switch
forward.
4. Drive the machine forward to aerate. When aerat-
ing, drive with the front tire next to the line of cores
from the previous pass to avoid overlap and get
even aeration.
5. Raise the tines when crossing hard surfaces, such
as driveways or sidewalks or going over things like
sprinkler heads
6. To obtain maximum benet, a second pass may be
made at right hand angles to the rst or by lapping
by 1/2.
Aerating TIPS
– Typical aeration core depth is 2 1/2" to 3" (60-
75mm). This gets below the surface compaction
and is easily performed. The machine is capable
of going deeper in the right soil conditions, but
noticeably more power is required. This increases
wear and tear on the entire drive train with minimal
additional benet from the increased depth.
– The machine may be turned with the tines in the
ground within limits. Too tight a turn will lead to the
tines tearing turf. A good rule of thumb is to limit
turns to about a 4' (1.2m) inside radius.
– When aerating a lawn, operate across the lawn.
Raise the tines at the end of the pass, turn around,
then lower the tines to continue on the next pass.
To nish, aerate the perimeter.
Use of the Depth Stops (J1 & J2)
– The depth stops enable consistent core depth in
varying soil conditions by setting the maximum core
depth. A consistent core depth keeps the machine
from bogging down when going from harder to
softer soil for more consistent operation and better
performance.
– Both depth stops need to be set to the same depth
to avoid twisting the aeration frame. The depth
stops set the maximum depth the tines penetrate
to. Actual depth may vary due to soil conditions,
tires, tire pressure and tine condition and wear.
– To get a consistent core depth, watch the depth
stops and depth arms. The depth arms should stay
tight against the depth stops pins when the tines
are in the ground. Occasional movement up is
acceptable and helps protect the tine assembly if it
rides over a rock or other buried object. Adjust the
down pressure with the pressure control to keep
the depth arms tight against this pins in normal
operation. Actual pressure is indicated by the pres-
sure gauge on the control panel,. In normal aerat-
ing conditions, 200-400 psi should give 2 1/2" to 3"
core depths.
Excess pressure:
– Wastes fuel. Pressure is generated by the hydrau-
lic lift pump. More pressure takes more power
– Creates excess heat. More pressure generates
more heat which must be removed via the oil cooler
and reservoir.
– Creates greater loads on the components in the lift
system.

OPERATOR PLATFORM
To reduce the space required, the operator platform
may be folded up. A latch is provided to hold it in the
"UP" position. the latch automatically engages when
the platform is raised. to lower the operator platform,
raise the latch to disengage it and lower the platform.
See Controls Section Pg. 13
LOADING THE MACHINE
DO NOT use split ramps when loading or unload-
ing the machine on a truck or trailer. Use full width
ramps rated for at least the machine weight ( Approx-
imately 1200 lbs (545 kg)) plus operator weight. Full
width ramps reduce the possibility of falling off the
ramp. Reduce engine speed and drive slowly when
loading or unloading the machine.
Secure the machine before transporting. Front Q
and rear Rtie down locations are provided to secure
the machine.
STORAGE
To prevent possible explosion or ignition of vaporized
fuel, do not store equipment with fuel in tank or
carburetor in an enclosure with an open ame (for
example, a furnace or water heater pilot light).
Before the equipment is put into storage for any
period exceeding 30 days, the following steps
should be taken.
1. Drain all fuel from the fuel tank and fuel lines.
2. Start the engine and run until all the fuel is used
from the carburetor oat bowl.
3. While the engine is still warm, drain the
crankcase oil and rell with the proper weight oil
corresponding to the season the equipment will
next be used.
4. Remove the spark plug and squirt a small
amount of engine oil into the cylinder. Turn the
engine over a few times to distribute the oil.
5. Lubricate the chains.
To put the equipment into service after an
extended period of storage:
1. Check for loose parts and tighten if necessary.
2. Check for cracked or broken tines and replace
as necessary.
3. Fill the fuel tank with clean, fresh fuel.
4. Check the engine and gear reduction case oil
levels with the engine in a level position.
5. Start the engine.
6. Check for fuel leaks.
7. Check operator present operation.
