General Safety Practices
Safety on the job should always be a top priority.
Training and experience are important factors in the
safe operation of equipment. Please consider the
following information and realize that safe operation is
a matter of using common sense as it relates to the
machine, its maintenance, the operator, the training,
and the operating conditions. These are general
safety instructions that apply to most turf maintenance
equipment.
This list includes many general safety
instructions as they relate to turf equipment.
This list does not encompass all hazards.
Common sense must always be used to
determine the safest way to operate a
machine under specic conditions.
TRAINING:
● Always read the manual, the decals, and the safety
warning decals before operating a machine for the rst
time.
● Always check the location and use of each control
before operating a machine for the rst time.
● Practice operating the machine in a safe area with no
obstructions until becoming familiar with the controls.
● If you have questions, ask your supervisor or call the
factory.
CLOTHING:
● Clothes should be snug t. Loose tting clothing is
hazardous because it may get caught in the mechanism
during service or operation.
● Remove jewelry before operation. Jewelry may get
caught in the mechanism.
● Wear shoes that will protect your feet. The protection
of leather shoes, boots, or steel toed safety shoes, is
required.
● Hard Hat: A hard hat should be considered when
using equipment on a golf course. The danger of being
hit by a golf ball should be a major concern as well
as protection needed while operating under trees or
around obstacles.
● Eye Protection: Safety glasses and/or face shields
should be worn when operating, as well as working in
close proximity to high speed rotary equipment. Watch
for rotary mowers, edgers, brush and string trimmers.
Rotary mowers can throw debris at speed up to 320
Km/h.
● Hearing: If the noise level of the equipment is too
loud, use ear protection.
● Do not use stereo headsets during operation. This
is a distraction that may lead to an accident. Headsets
also make it difcult to hear other people and other
equipment while operating the machine.
● Gloves: Use gloves to protect your hands. Use gloves
when handling sharp or hazardous objects.
● Respirators: When operating in dusty, windy
conditions, wear a respirator. This is also an important
consideration if operating equipment while spraying
chemicals and fertilizers.
THE OPERATOR:
● The operator should never use a machine while
under the inuence of alcohol or drugs.
● The operator should be aware of the hazards of
working in the sun and should take proper precautions
to avoid heat stress and dehydration. Use sun screen
products when necessary.
● The operator should never attempt to ride a machine
that is not designed for that propose. Do not allow
others to ride a machine that is not designed for
passengers.
● Do not operate any equipment at unsafe speeds.
Speeds should be reduced when turning or operating
on slopes. The operator must use common sense to
determine a safe speed based on the equipment, the
load, the slope, the surface, and other conditions that
may affect safe operation.
● The operator must be aware of the conditions around
the machine. Be careful to observe other people and
machines in the area.
Recognizing Safety Warnings Used In Manual
LOOK FOR THE SAFETY HAZARD WARNING SYMBOL
The symbol is used to alert the operator of safety hazards.
It is used in conjunction with the words DANGER, WARNING, and CAUTION.
“DANGER” identifies immediate hazards which will result in serious injury or death.
“WARNING” identifies potential hazards which could result in serious injury or death.
“CAUTION” identifies hazardous situations which may result in minor injury and/or could result in
damage or destruction of equipment.
WARNING CAUTION
DANGER
SAFETY

85399 Rev B
● Beware of slippery conditions. Wet turf can be
encountered on slopes, when turning or stopping, or
at higher speeds.
● Keep hands and feet away from cutting devices and
drive components. Shut off the engine and remove the
key or spark plug wire when servicing cutting devices
or drive components.
● Care should always be taken when mounting and
dismounting a riding machine. Prevent injuries and
falls by making sure the operator does not slip. Unless
it is an emergency, do not jump off a machine. Injury
may result when an operator’s foot slips trying to jump
from a machine.
● If required to lift, an operator should ask for help if
the object is too heavy. The operator should lift with the
legs instead of the back. Care should be taken to avoid
twisting the back while lifting a heavy load.
● Never allow children to operate the machine.
THE MACHINE:
● Do not modify the machine in any manner. Always
check the machine to make sure it is in good working
order.
● Do not place hands or feet near moving or rotating
● parts. Check that all guards are functional and
properly installed. Do not operate a machine without
all guards installed.
● Do not use your ngers or hands to check for leaks.
High pressure leaks can puncture the skin and force oil
into the body. This can cause severe injury or death.
● Check tires. Inate to pressure shown on tire.
● Check to assure that all controls are in good
operating condition.
● Do not overload machinery. The components
are designed for certain weights and capacities.
Overloading machine will cause unsafe conditions.
● Shut off the engine before servicing the machine.
Check machines on a level area. Machines on a slope
may roll when the engine is off.
● Refer unfamiliar repairs and adjustments to
mechanics that have been trained to do them
properly.
● Replace decals that are damaged or illegible.
THE ENGINE:
● Do not run the engine in an enclosed area. The
exhaust gases contain carbon monoxide, an odorless
and deadly poison. The engine exhaust from this
product contains chemicals known to the State of
California to cause cancer, birth defects or other
reproductive harm.
● Do not refuel machines indoors or in an unventilated
area. Do not over ll. Do not add fuel while the machine
is hot because spilled fuel may cause a re. Use
fresh gasoline. Stale fuel can gum the carburetor and
can cause leakage. Check the fuel lines and ttings
frequently for cracks and leaks.
● Pull the starter cord slowly until resistance is felt.
Then pull the cord rapidly to avoid kickback and to
prevent hand or arm injury.
● Do not remove the fuel tank cap or ll fuel tank while
the engine is hot or running. Allow the engine to cool
before refueling.
● Do not operate the engine if gasoline is spilled. Do
not operate the engine when the smell of gasoline
is present or if any other explosive conditions exist.
Move the equipment away from the spill and avoid any
ignition until the gasoline has evaporated.
● Do not store, spill, or use gasoline near an open
ame. Do not store, spill, or use gasoline near a stove,
furnace, water heater, or appliance that uses a pilot
light or can create sparks.
● Do not choke the carburetor to stop the engine.
Whenever possible, gradually reduce the engine
speed before stopping.
● Do not tamper with the governor springs, links or other
parts to increase the engine speed. Run the engine at
the speed set by the equipment manufacturer.
● Keep the cylinder ns and the governor parts free of
dirt, grass, and debris which can affect engine speed.
● Do not transport the engine with fuel in the tank.
● Prevent accidental starting by removing the spark plug
wire(s) when servicing the engine or the equipment.
Disconnect the negative wire from the battery terminal
if the engine is equipped with an electric starting
system.
● Do not strike the ywheel with a hammer or any
hard object. This may cause the ywheel to shatter
during operation. Use the correct tools to service the
machine.
● Do not check for a ignition spark with the spark plug
removed. Use an approved tester.
● Do not crank the engine with the spark plug removed.
If the engine is ooded, place the throttle in fast and
crank until the engine starts.
● Do not start the engine with the air cleaner and/or the
air cleaner cover removed. Do not operate the engine
without a mufer. Replace the mufer if it is leaking or
worn. Replace only with correct mufer. Do not touch a
hot mufer, cylinder, or n. It will cause burns.
● Do not operate the engine with an accumulation of
grass, leaves, or other combustible material in the
mufer area.
● Do not use the engine on any forest covered, brush
covered, or grass covered unimproved land unless
a spark arrester is installed in the mufer. The spark
arrester must be maintained in good working order.
In the State of California, the above is required by
law (Section 4442 of the California Public Resources
Code). Other state may have similar laws. Federal
laws apply on federal lands.

DESCRIPTION OF OPERATOR CONTROLS
(See Figure 2 and Figure 3)
The Operator Controls are located on the dashboard and
the operator platform. On the dashboard, the controls
are the engine ignition, engine throttle & choke controls,
tine depth control and directional control handles. The
foot operated tine switch is on the operators platform.
Ensure that all operator controls are in good operating
condition. Do not alter operator controls and/or operate
the Aerator with defective or non-operational operator
controls.
Operator Platform Locking Handles (See Figure 2):
The operator platform can be tipped up and locked in
a raised position for maintenance, storage or during
transportation on a trailer to the worksite. Do not
operate the aerator when the platform is raised.
Engine Controls (See Figure 3):All engine controls
are on the dashboard. Use the keyed three position
ignition switch (off, run & start), throttle and choke to
control the engine. Set at full throttle during operation,
use partial throttle for warm up and slow transport. A
fuel shutoff valve is located on the engine.
Directional Control Handles (See Figure 3): The right
and left handles control turning, speed and forward/
reverse direction. Pushing both handles forward makes
the machine go forward. The further the handles are
pushed forward the faster the machine will go. If the
handles are pulled backwards, the machine will go in
reverse. The further the handle is pulled backwards, the
faster the machine will backup. When only one handle is
pushed forward (or backwards) the machine will turn in
that direction. Turning speed will increase the further the
handle is pushed forward (or backwards).
Choose a speed that is comfortable for the operator
to safely control the machine. Decrease speed when
operating in an area of close obstacles.
Slowly Engage The Direction Control Handles.
Fast Engagement Can Cause Loss of Control of
the Aerator.
The directional handles will not act as a brake when
released. If the directional handles are released when
the Aerator is going up or down a slope, the machine
can freewheel forwards (or backwards).
Foot Operated Tine Switch (See Figure 2): The foot
operated switch controls the raising and lowering of the
tine assemblies. When the switch is stepped on, the
tine assemblies hydraulically lower to put the tines into
the ground. Your foot must stay on the switch to keep
the tines in the ground. When the switch is released,
the tine assemblies automatically raise removing the
tines from the ground.
Tine Depth Setting Control (See Figure 3): The
tine depth setting control controls the depth of tine
penetration by limiting the lowered position of the tine
assemblies. Move the stop to the desired hole setting.
The depth setting range is 1-1/2” to 5” - because of
soil and tine conditions (new vs worn) the settings are
approximate. Adjust as needed.

 Check - All guards are in place. Do Not Operate
Without Guards In Place.
 Check - Retighten any loose nuts and screws to
ensure safe operation.
 Check - The work site for above and below
ground obstructions and/or dangerous areas.
WORK SITE PREPARATION
Under certain conditions (in very loose and uneven
turf), the Aerator tines can reach a depth of 5” plus
inches. Damage will occur to any buried object that
the tines may come in contact with. Plan your path
and know the location of any below ground as well as
above ground objects that could be damaged by the
aerating process.
Locate and mark all shallow buried electric service,
cable TV, telephone, outdoor lighting, and any other
buried cable that may be damaged by the aerating
process.
Locate and mark all irrigation heads, above and below
ground irrigation control boxes, and any shallow
buried irrigation lines that may be damaged by the
aerating process.
Locate and mark any shallow buried natural gas,
propane gas, or other gas or fuel line that may be
damaged by the aerating process.
Locate and mark any shallow buried roof drain pipes,
drain tiling, drain catch basins, or any other buried
drainage items that may be damaged in the aerating
process.
MAXIMUM ANGLE OF OPERATION
TO AVOID SERIOUS INJURY,
Do Not Operate the Aerator On Slopes
Over 15° Degrees.
Aerator Can Tip, Roll Over, Or Roll Back Onto
Operator.
Do not operate the Aerator on slopes over 15°degrees.
Serious injury can occur. When operated on steep
slopes or when operated in an unsafe manner, the
Aerator can tip, roll over, or roll back on to the operator,
causing serious injury. When aerating on minor slopes,
never operate straight up or down or across the slope.
Approach a minor slope moving up and down at a 45°
degree angle to the slope.

85399 Rev B
Steering characteristics will change when traveling along
on a slope. The front wheel casters will want to steer
down the slope instead of following the slope. Correct
this by using the directional controls to slightly steer up
the slope.
OPERATING GROUND SPEED
Operating ground speed should be at the normal factory
set speed (5-1/2 to 7 MPH), but can vary depending
on the conditions of the turf and work site. Vary the
operating ground speed to suit conditions. Reduce
speed when on slopes and reduce speed when near or
next to obstacles.
Forward ground speed is controlled
by the directional control handles
and engine throttle setting .
ENGINE STARTING AND STOPPING PROCEDURES
To Start Engine:
2. Place Fuel Shutoff in ON Position.
3. Set Engine Throttle & Choke.
4. Use .
6. After Start, Reset Throttle & Choke, Slow Engine
Allow Engine & Hydraulics To Warm Up.
Engine should be set at full speed during operation
To Stop Engine:
1. Tines must be out of the ground.
2. Reset Throttle to Idle and Allow Engine to Return to
Idle Speed (Briggs and Stratton).
3. Ignition Switch key to STOP Position.
4. Place Engine Fuel Shutoff To OFF Position.
To stop the engine in an emergency situation,
engine throttle to slow & turn off ignition.
PLANNING AERATING PATH
Move the XT8 to the area being aerated before lowering
the tines. To prevent damage to tines, do not operate
the Aerator with the tines down across any hard surface,
rock covered areas, over obstacles or across pavement.
For best results, plan a path with straight lines. Limit
turns to gentle sweeping turns and normal turns at the
end of a row. Tight turns are possible with the aerator,
but the aerating holes may be enlarged if turns are too
tight.
Aerate the turf more than once to maximize the number
of holes. Aerate the same work site at least twice,
changing direction of travel by 90° degrees. Change
to 45° degrees if aerating for a third pass. For safety
reasons, only do minor slopes at 45° degree angles to
the slope. Never operate the Aerator on steep slopes.
Aerating In Tight Areas
All lawns will have areas that are too tight to turn.
To turn the Aerator in a tight area lift the tines out
of the ground. Pull back on the Directional Control
handles and back out of the tight spot. Go forward and
reposition the machine to return to your planned path.
Moving In Reverse
When in reverse, the tines can be left in the ground
for very short distances. In very wet conditions the
Aerator may tear the turf when turn with the tines in
the ground. If soil conditions are such that tearing of
the turf is occurring during reverse operations, lift the
tines before going backwards.
INSPECTION DURING OPERATION
Stop and check the depth of the tine penetration by
checking the holes with a pen or pencil.
Visually inspect the tines often during the aerating
process to ensure that they have not become plugged
with stones, roots or debris. A plugged tine will still make
a hole, but will compact the soil in the hole instead of
removing a core. Compaction of the soil is the opposite
of the effect desired by the aerating process. When
inspecting or cleaning the tines, STOP THE ENGINE
and move the Aerator to a level surface. Use caution
and wear the proper protective items when working
around the tines.
TO AVOID SERIOUS INJURY,
Be Aware of Sharp Tines. Wear Protective Items
When Working Around Tines.

OPERATING DIRECTION CONTROL HANDLES
Slowly push the direction handle forward to engage the
forward direction. Slowly pull the handle back to engage
reverse direction. Slowly pushing or pulling only one
handle at a time will cause the machine to turn. Fast
engagement of the direction can cause the Aerator to
surge forward (or reverse) causing the operator to loose
control of the machine. Releasing the directional control
handles will return the drive to a neutral position and the
machine will stop.
Slowly Engage The Direction Control Handle. Fast
Engagement May Cause Operator To Loose Control
Of The Aerator. Fast Engagement On Uneven
Ground Can Cause The Aerator To Tip Or Roll Over.
The directional handles will not act as a brake when
released. If the directional handles are released when the
Aerator is going up a slope, the machine can freewheel
backwards. If the directional controls are released when
going down a slope, the machine can freewheel forward.
To Move Forward and Reverse From a Stopped
Position.
A. Slowly push both handles equally forward to go
forward in a straight line. The further the handles are
pushed forward, the faster the machine will go.
B. Slowly pull both handles equally backwards to go in
reverse in a straight line. The further the handles are
pulled back, the faster the machine will go.
To Turn the Aerator From a Stopped Position.

WARNING
TO AVOID SERIOUS INJURY,
Never Perform Any Inspection With the
Aerator Engine Running.
Wear the appropriate safety gear when inspecting
the Aerator.
Before each use, check the following items. Refer any
repairs to service personnel.
●
Inspect fuel levels. Do not ll fuel tank(s) over 3/4 full.
● Check for proper lubrication of the entire machine.
● Check for proper oil levels in the engine. Check engine
oil with engine setting level.
● Check for proper oil levels in the hydraulic reservoir.
● Check condition and sharpness of the tines. Check for
plugged or blocked tines.
● Inspect all operator controls for proper operation. Do
not operate any machine with missing, inoperative or
damaged controls.
● The Aerator operates with vibration. Before and after
each use, check and retighten any loose nuts and
bolts. Inspect the entire machine for loose fasteners.
● Inspect for damaged, inoperable, or missing guards
and components. Do not operate any machine
with missing, inoperable, or damaged guards and
components.
● Check for a buildup of dirt or debris on the machine.
Clean machine before use. Do not high pressure
wash.
Storage
TO STORE THE Aerator over an extended period,
clean all surfaces and remove any remaining aeration
cores from the machine. Use only Low Pressure Wash
on the machine. High pressure washing can wash away
the grease from the bearings.
Check the tines and remove any cores, stones, or
debris. Apply a light lm of light machine oil to the tines
to control rust. See the lubrication directions and follow
the procedures.
Remove fuel from gas tank and run engine until
carburetor is empty. Prepare engine in accordance with
engine manufacturer’s directions.
Place plywood under the tines to provide protection if
the tine wheel assemblies slowly settle and lower during
prolong storage.
TO RETURN TO SERVICE AFTER EXTENDED
STORAGE, inspect the entire machine for any damage
that may have occurred during storage. Look for loose
or missing parts. Refer any needed correction to the
proper service level maintenance personnel. Check all
lubrication levels.
Troubleshooting Table

85399 Rev B
Chassis: Lightly lubricate all pivot points with light machine oil.
Chains, Sprockets And Pivot Points: All bearings in the drive train require no lubrication. Periodic
inspection should be done to insure that any worn bearings are detected and replaced.
Lubricate and protect chain from rust and moisture with a very light coating of machine oil.
Engine: CHECK OIL LEVELS DAILY. Follow the engine manufacturer’s manual for intervals of oil change,
proper oil types, and ll levels for the engine. Check oil with engine sitting level.
Hydraulic System: Use 20/50 MOTOR OIL. See the decal on the front of the reservoir mounting bracket
for ll levels. Change hydraulic oil and lter annually.
TO AVOID SERIOUS INJURY, Never Perform Any Service or Adjustment Procedures With the
Engine Operating.
All Of The Following Lubrication, Service, or Adjustment Procedures Involve Or Are Near
Rotating and Moving Parts.
Use Caution When Working Near the Tine Reel Assemblies. Tines Are Sharp and Can Easily
Cut Hands and Feet. Wear the appropriate safety gear.

CLEANING AND HARDWARE INSPECTION
The Aerator operates with vibration. Check and retighten nuts and screws frequently to ensure safe operation.
Keep the Aerator free of any buildup of dirt, cores or debris. Low pressure wash only. DO NOT HIGH PRESSURE
WASH. High pressure washing can force water into the sealed bearings washing away the lubrication.

V-BELT ADJUSTMENT (See Figure 7)
The hydraulic pumps are driven by a V-belt from the engine. Tension on the V-belt is
maintained by an idler pulley. The idler can be adjusted to set the V-belt tension.
Before adjusting, inspect the V-belt wear or damage and check the bearings in the idler
pulley. Check the hardware holding the engine and the pumps to the frame. Check for a
buildup of dirt and debris in the V-belt grooves pulleys, clean as needed.
Check for free movement of the idler mounting plate. The plate must be free to slide. Clean
and adjust as needed.
To adjust the idler pulley, turn the adjuster screw (accessible only from under the machine)
to compress the spring. Tighten the adjuster until the spring has been compressed to a
measure of 2-1/2” to 2-5/8” (63.5mm to 66.7mm).
Test and repeat adjustment if required. Replace V-belt if proper operation cannot be
reached with adjustment.

CHAIN IDLER SPROCKET ADJUSTMENT (See Figure 8)
INSIDE CHAINS ARE FOR TINES - OUTSIDE CHAIN ARE FOR REAR WHEELS
The chain idler sprockets (two per side, total four) can be adjusted to remove excess slack in the
chain caused by normal chain wear or stretch. Before adjusting idler sprocket position, ensure that
the chain and all sprockets have been cleaned and that the chain seats properly on the sprockets.
A build-up of dirt on the sprockets or chain can cause the chain to become too tight. Inspect all the
sprockets, bearings, and the chain for wear or damage. Inspect for sprocket wear.
TINE CHAINS - With the tine reel elevated, loosen the idler sprocket and move along the slot to
adjust to the proper tension setting. Chain should have a up and down movement of 1/2” inch
to 3/4” inch (12 mm to 19 mm). Take measurement half way along the upper half of the chain
between the tine sprocket the hydraulic motor. Retighten idler sprocket and recheck tension setting
measurement. Set both sides with the same tension.
REAR WHEEL CHAINS - With the rear tires elevated, loosen the idler sprocket and move along
the slot to adjust to the proper tension setting. Chain should have a up and down movement of 1/2”
inch to 3/4” inch (12 mm to 19 mm). Take measurement half way along the upper half of the chain
between the rear wheel sprocket the hydraulic motor. Retighten idler sprocket and recheck tension
setting measurement. Set both sides with the same tension.

DIRECTION CONTROL HANDLE ADJUSTMENTS
FIXED HANDLE ADJUSTMENT (See Figure 9) - The xed handle limits the forward ground speed
by limiting the forward movement of the direction control handles. Ground speed can be changed
(adjusted) by moving the xed handle location. Speed adjustment range is between 5 mph to 7 mph
(8 Kph to 11.2 Kph).
● Loosen the upper carriage bolt (both sides) on the xed handle. The handle will pivot forward or
backward on the lower carriage bolt.
● Adjusting handle forward will increase speed, adjusting backwards will decrease speed.
● Adjust as desired. Make sure the xed handle is even on both sides and the direction control
handles equally touch the xed handle. Retighten the carriage bolts.
DIRECTION CONTROL HANDLES (See Figure 10) - The direction control handles can be adjusted
to correct for unequal steering. This adjustment will also correct unequal contact of the handles to
the xed handle.
● Remove the front cover and locate the yokes on the upper end of the direction control rods.
● Loosen the lock nut on the yoke on the side you are adjusting. Remove the pin holding the yoke
to the control.
● Turn the yoke to adjust. Limit adjustment to 1/2 turn of the yoke and test result. Turning clockwise
will increase speed, counterclockwise to decrease (as viewed standing in front of the machine
looking back)
● Test, tighten lock nut and replace front cover.
