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 di󰀩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 a󰀨ect 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

85540-85541
● 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 o󰀨 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 o󰀨 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 o󰀨 the engine before servicing the machine.
Check machines on a level area. Machines on a slope
may roll when the engine is o󰀨.
● 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 a󰀨ect 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 mu󰀪er. Replace the mu󰀪er if it is leaking or
worn. Replace only with correct mu󰀪er. Do not touch a
hot mu󰀪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
mu󰀪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 mu󰀪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.

Engine Controls: All engine controls are on the engine.
● On the Briggs & Stratton engine, a throttle is located on
the right hand side of the engine. The throttle controls the
engine speed and has a shut down “Stop” position. A fuel
shuto󰀨 valve is located on the right side the engine.
● The Yamaha engine does not have a throttle. The engine
speed will automatically go to full speed after starting.
The Yamaha engine has a choke for starting and a on/o󰀨
switch for shut down. The fuel shuto󰀨 for the Yamaha is
part of the fuel tank selector.
Neutral Lock Knob: When the engine is not running, the
front drive wheels are locked and
will not turn. The neutral lock knob
allows the user to set the transaxle
in “neutral” which allows the front wheels to turn. Pull the
knob out and move to the side to unlock the wheels and
latch the knob. When the engine is running, the knob must
be unlatch before the transaxle will work.
Direction Control Handle (See Figure 3): The handle
controls both forward/reverse direction and speed. Pushing
forward on the handle makes the machine go forward. The
further the handle is pushed forward the faster the machine
will go. If the handle is pulled backwards, the machine will go
in reverse (back up towards operator). The further the handle
is pulled backwards, the faster the machine will backup.
Forward and Reverse ground speed is controlled
by the Direction Handle.
Choose a speed that is comfortable for the operator to
walk safely behind. Decrease speed when operating in an
area of close obstacles.
Slowly Engage The Direction Control Handle. Fast
Engagement On Uneven Ground Can Cause The
Aerator To Tip Or Roll Over.
The direction handle will not act as a brake when released.
If the direction handle is released when the Aerator is
going up a slope, the machine can freewheel forwards or
backwards towards the operator.
Transport Locking Pin (See Figure 4): The transport
locking pin secures the transport wheels in a lowered
position for transporting, maintenance or storage. The pin
must be removed during operation. Stored the pin in the
“Unlocked” hole in the wheel linkage (See Figure 4).
Transport Wheels Lift Handle (See Figure 4): The
transport wheels lift handle, located across the rear of the
handlebar, raises or lowers the transport wheels. Push
down on the transport handle to raise the transport wheels
so that the tines go into the turf. Pull up on the transport
handle to lower the transport wheels and remove the tines
from the turf.
Depth Setting Stop (See Figure 4): The depth setting
stop limits the depth of tine penetration by limiting the
raised position of the transport wheels. If the tines are
penetrating too deep, the transport wheels will touch
the ground and keep the tines from going any deeper.
Two settings are available - one at 1-3/4” inches and
one at 2-3/4” inches (when tines are new). Move the
stop to the desired hole on both sides of machine.
● 1-3/4” setting - range is 1-1/4” to 1-3/4”
● 2-3/4” setting - range is 2-1/4” to 2-3/4”
Because of soil and tine conditions the settings are
approximate.

1. Pull Transport Wheel Lift Handle Up. Tines must be out
of the ground. Ensure that the Direction Control Handle
is disengaged.
2. Place Fuel Shuto󰀨 in ON Position. On the Yamaha
engine use the fuel selector to select either the front or
rear fuel tank.
3. Set Engine Throttle (or choke on Yamaha)
4. Pull Starter Rope To Start Engine.
6. Reset Throttle (or choke), Allow Engine To Warm Up.
Engine should be at full speed (3600 RPM)
during operation
To Stop Engine:
1. Release Direction Control Handle.
2. Pull Transport Wheel Lift Handle Up. Tines must be out
of the ground.
3. Reset Throttle to Idle and Allow Engine to Return to Idle
Speed (Briggs and Stratton).
4. Place Throttle to STOP Position (Use On/O󰀨 switch on
Yamaha engine)
5. Place Engine Fuel Shuto󰀨 To OFF Position.
To stop the engine in an emergency situation,
release the direction control handle and put the
engine throttle in the STOP position.
On Yamaha engines, Use the On/O switch .
OPERATING DIRECTION CONTROL HANDLE
Slowly push the direction handle forward to engage
the forward direction. Slowly pull the handle back to
engage reverse direction. Fast engagement of the
direction will cause the Aerator to surge forward (or
reverse) causing the operator to loose control of the
machine. Releasing the direction control handle will
return the drive to a neutral position.
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 Direction Control will not act as a brake when
released. If the Direction Control is released or
disengaged when the Aerator is going up a slope, the
machine can freewheel and roll backwards towards
the operator. If the Direction Control is released or
disengaged when going down a slope, the machine
can freewheel forward.
OPERATING GROUND SPEED
Operating ground speed should be at a normal walking
speed, but can vary depending on the conditions of the
turf and work site. Vary the operating ground speed to
suit conditions. Reduce speed by the direction control
to slow down when near or next to obstacles.
Forward ground speed is controlled
by the direction control handle.

PLANNING AERATING PATH
Move the XT5 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 and
gentle sweeping turns.
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
TURNING THE AERATOR AND MOVING IN
REVERSE
To Turn the Aerator
Apply pressure on the appropriate side of the handlebar
to guide (steer) the aerator. Apply the pressure to the
left side of the handlebar to turn left, apply pressure
to the right to turn right. For best aerating results, limit
turns to 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.
Make sure you keep the machine rolling while turning.
In very wet conditions the Aerator may tear the turf
when turn with the tines in the ground. To avoid
tearing in these conditions, raise the tines and use the
direction control to backup and reposition the aerator
for the nest pass.
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 using the transport wheels lift handle. Pull back
on the Direction Control handle and back out of the
tight spot. While backing up, pull on the handlebar in
the direction you want to turn to swing the machine
around. 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
or raised. If soil conditions are such that tearing of the
turf is occurring during reverse operations, lift the tines
before going backwards. The reverse speed is slower
than the forward speed but caution must be used when
in reverse to keep hands and feet away from the tines.
TO AVOID SERIOUS INJURY,
Keep Hands and Feet Away From Tines Especially
When Operating In Reverse.
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 e󰀨ect 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.
Be aware of any damage to the turf caused by the
wheels dragging during turns or on uneven surfaces.
Check the depth stop.

TRANSAXLE V-BELT ADJUSTMENT (See Figure 6)
The transaxle is driven by a V-belt from the engine. Tension on
the V-belt is maintained by an idler pulley that is mounted to
the deck. 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 transaxle to the frame. Check for a buildup of
dirt and debris in the V-belt grooves pulleys, clean as needed.
To adjust the idler pulley, loosen the nut on the pulley (accessible
only from under the machine) and slide the pulley along the
slot. Tension the belt with an approximate 1/4” of deection in
the belt measured between the engine and transaxle pulleys.
Test and repeat adjustment if required. Replace V-belt if proper
operation cannot be reached with adjustment.
DIRECTION CONTROL HANDLE CABLE ADJUSTMENT
(See Figure 7)
The direction control cable and the reverse handle can be
adjusted to acquire correct positioning for forward/reverse
speeds and to recenter the “neutral” position of the direction
handle.
Adjusting the control cable will change the forward speed.
The correct position is where the forward handles contact
the handlebar when accuated. There should not be a gap
between the forward handles and the handlebar when
fully accuated. Make minor adjustments. To adjust the cable,
loosen the nuts holding the cable, then change the adjustment
by turning the nuts one turn at a time until forward speed is
corrected. Secure adjustment by tightening the adjuster nuts.
Once the forward handles are located correctly adjust the
reverse handle into position by loosening the nut in the slot
on the handle. Locate the handle so when fully accuated it
contacts the handlebar. There should not be a gap between
the reverse handle and the handlebar when fully accuated.
Ensure that the machine will freewheel when the “neutral” knob
is pulled out (located on the right side of the frame). Make sure
that the machine will not creep or move on its own without the
direction handle being activated. Test and repeat adjustment
if required.

CHAIN IDLER SPROCKET ADJUSTMENT
(See Figure 8)
The chain idler sprockets (one per side - located under the side chain guards) 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.
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 above the idler sprocket, see gure 8. Retighten idler sprocket and recheck tension
setting measurement. Set both sides the same.
If the chains cannot be adjusted within the movement of the idler sprocket, the chain can be shortened by
removing a half link. Each chain has two half (o󰀨set) links. Remove one (or both) half links. The shortened
chain will reposition the idler in the slot allowing for extra adjustment. Both chains should be the same.
