capabilities.
• Always look where you are going and be aware of your
surroundings.
• Listen to the machine and be aware of any change.
• Feel the machine and its responses from both your inputs
and the environment.

4
English
EN
• Follow daily and weekly checklists, making sure
electrical connections are secured and bolts are tightened.
• Replace damaged parts immediately
.
• Never operate mower without a proper trail shield,
discharge cover, switch control, or other safety device in
place and in working order. Do not operate the mower
with damaged safety devices; doing so can result in
injury.
• Repair or replace any damaged components before
restarting and operating the lawnmower.
• Only use approved replacement parts.
• Minimize exposure to water. Do not drive into water. Do
not leave in rain. Do not clean with pressurized water or
hose.
• Always store your lawnmower indoors. When not in use,
the mower should be stored indoors in a dry and locked
place, out of reach of children.
2.3 MOWING AREA
• Before mowing any area, thoroughly inspect the area for
any hazards. Walk the area to ensure there is adequate
traction and no holes, drop-of
fs, or hidden objects that
could cause issues. Clear the area of objects such as
rocks, wire, toys, etc., which could be thrown by the
blades.
• Be sure the area is clear of bystanders before operating.
Stop machine if anyone enters the area.
• Plan your mowing pattern in such a way as to avoid
discharging material toward roads, sidewalks, bystanders,
vehicles, windows, etc. Do not discharge material against
a wall or obstruction. Doing so may cause the discharged
material to ricochet back toward the operator.
• Do not mow anything but grasses.
• Stop the blades when crossing dirt, gravel, or paved
surfaces.
• Avoid dangerous environments. Do not operate the
mower in the rain or in wet or damp grass. To reduce the
risk of electric shock, do not expose to water or operate
on wet ground.
2.4 MOWING
• For riding mower models, always remain seated while
operating machine.
• Do not operate on inclines greater than 15 degrees.
•
Mow only in daylight or in good artificial light. Never
rush a mowing job.
• Never attempt high-speed maneuvering, especially in
crowded, congested areas or on slopes.
• In order to avoid contact with the blade or injury caused
by a thrown object, stay in the operating zone behind the
handles, and keep children and bystanders at least 100ft
(30m) away from the mower while it is in operation. Stop
the motor immediately if someone enters the mowing
area.
• Look down and behind before and while moving
backwards.
• Slow down before turning.
• Do not mow in reverse unless absolutely necessary
.
• When moving in reverse, SLOWLY pull right and left
Drive Control Levers rearward and avoid sudden
movements. Rapid movement of the Drive Control
Levers in either direction could result in a reaction of the
machine that can cause serious injury.
• Do not put hands or feet near rotating parts or under the
cutting deck. Contact with the blade can amputate hands
and feet.
• If the mower starts to vibrate excessively, stop the motor
and check for the cause immediately. Excessive vibration
is generally a sign the mower is not functioning properly.
• Stop the motor and wait until the blade comes to a
complete stop before unclogging the chute. The cutting
blade will continue to rotate for a few seconds after the
motor is shut off. Do not place any part of your body in
the blade area until you are sure that the blade has
stopped rotating.
• If lawnmower strikes a foreign object, stop the machine,
rotate the ignition switch to "OFF" position, then, if it is
safe, inspect for damage.
• Don't force the lawnmower.
• Do not use the mower for any job except that for which it
is intended.
2.5 SERVICING
• Turn off and remove key before servicing, cleaning, or
removing material from the ride-on mower.
•
Do not reach under blade guard. Keep hands, feet, and
clothing way from rotating blades.
• To reduce personal risk and damage to the machine, never
clean with pressure washer.
• Maintain your mower. Keep cutting edges sharp and
clean to ensure the best performance and safe operation.
2.6 CHILD SAFETY
Tragic accidents can occur if the operator is not aware of the
presence of children. Children are often attracted to the
machine and the mowing activity. Never assume that children
will remain where you last saw them.
•
Never leave machine unattended with key in switch,
especially with children present.
• Keep children out of the mowing area and under the
watchful care of a responsible adult other than the
operator.
• Do not allow children under the age of 14 to operate this
mower. Children who are 14 years of age and older must
read and understand the operating instructions and safety
rules in this manual, and must be trained and supervised
by a parent.
• Always disengage deck blade switch and turn key to
“OFF” position and remove key.
• Stay alert, and turn the mower off if a child or any other
person enters the mowing area.
5
English
EN
• Use extreme care when approaching blind corners,
doorways, shrubs, trees, or other objects that may obscure
your view of a child who may run into the path of the
mower.
•
Before and while backing, look behind and down for
small children.
• Never carry children on the mower with you, even with
the blade(s) shut off. They may fall off and be seriously
injured or interfere with safe machine operation. Children
who have been given rides in the past may suddenly
appear in the mowing area for another ride and be run
over or backed over by the machine.
2.7 USE A RAMP
• Use extreme caution when loading and unloading this
mower onto a truck or trailer with a ramp.
• Use only a single, full-width ramp. This provides a
surface for the mower frame to contact if the unit starts to
tip backwards. It also reduces the risk of a wheel going
of
f and the machine tipping over.
• Do not exceed a 15-degree angle between the ramp and
the ground or between the ramp and the trailer or truck.
• Become familiar with the mower’s controls and confident
in its smooth operation before attempting to drive it up or
down a ramp.
• Use slow drive mode and drive carefully.
• Avoid any sudden movement of the controls and use only
slow, even acceleration.
2.8 TOWING
• Tow only with a machine that has a hitch designed for
towing. Do not attach towed equipment except at the
hitch point.
• Follow the manufacturer
’s recommendation for weight
limits for towed equipment and towing on slopes.
• Never allow children or others in or on towed equipment.
• On slopes, the weight of the towed equipment may cause
loss of traction and loss of control.
• Travel slowly and allow extra distance to stop.
2.9 BATTERY AND CHARGER
• Prevent unintentional starting. Ensure the switch is in the
of
f-position before connecting to battery pack, picking up
or carrying the appliance. Carrying the appliance with
your finger on the switch or ener
gizing appliance that
have the switch on invites accidents.
• Disconnect the battery pack from the appliance before
making any adjustments, changing accessories, or storing
appliance. Such preventive safety measures reduce the
risk of starting the appliance accidentally.
• Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type of
battery pack may create a risk of fire when used with
another battery pack.
• Use appliances only with specifically designated battery
packs. Use of any other battery packs may create a risk of
injury and fire.
• When battery pack is not in use, keep it away from other
metal objects, like paper clips, coins, keys, nails, screws
or other small metal objects, that can make a connection
from one terminal to another
. Shorting the battery
terminals together may cause burns or a fire.
• Under abusive conditions, liquid may be ejected from the
battery; avoid contact. If contact accidentally occurs,
flush with water. If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery may cause
irritation or burns.
• Do not use a battery pack or appliance that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behavior resulting in fire, explosion or risk
of injury.
• Do not expose a battery pack or appliance to fire or
excessive temperature. Exposure to fire or temperature
above 130°C may cause explosion. The temperature of
130°C can be replaced by the temperature of 265°F.
• Follow all charging instructions and do not charge the
battery pack or appliance outside of the temperature range
specified in the instructions. Charging improperly or at
temperatures outside of the specified range may damage
the battery and increase the risk of fire.
• Have servicing performed by a qualified repair person
using only identical replacement parts. This will ensure
that the safety of the product is maintained.
• Do not modify or attempt to repair the appliance or the
battery pack (as applicable) except as indicated in the
instructions for use and care.

the reverse mode button is illuminated in green. Remember
that a careless fraction of a second is suf
ficient to inflict
death or serious injury
.
WARNING
Be especially careful before and when backing with the
bagger kit (not provided) installed, as it may limit visibility
.
Always look closely behind and down for small children,
bystanders, and pets and move the mower slowly to prevent
back over accidents that can cause death or serious personal
injury
.
8.2.6 SAFETY INTERLOCK SYSTEM
This mower features a Safety Interlock System to protect the
operator by shutting off the blades if the operator leaves the
seat with the blades running. T
est the system before each use
to be sure it is working correctly.
1. Make sure direction control switch is in neutral (N)
position and PTO switch is down.
2. Install start key and turn to start position.
3. Raise the PTO switch to activate blades.
4. Briefly lift off the seat, but do not get off the mower.
The blades should shut off within 5 seconds. If they don’t,
contact customer service. Do not operate the mower until the
safety interlock system has been repaired.
8.2.7 USE THE USB PORT
USB port
The USB charging port provides charging power of 5 Volts
DC at up to 2.1 amps for your cell phone, MP3 player, or
other USB devices. Consult the owner
’s manual for your
device for specific charging requirements.
Connect one end of a USB cable (not provided) to your
device and the other end to the USB charging port on the
mower, to begin charging your device.
NOTE
Attempting to charge devices rated more than 2.1 amps
could damage the USB charging port and/or the mower
.
NOTE
The USB port is only powered when the machine starts.

WARNING
Never use headphones or any electronic device, such as a
smart phone or tablet, while operating the mower.
Distracted operation can result in an accident that could
result in death or serious personal injury to the operator or a
bystander.
8.2.8 OPERATION TIPS
• Keep mower blades sharp.
• Make sure the lawn is clear of stones, sticks, wires, toys,
tree nuts, tree branches, and other objects that could
damage the lawn mower blades or motor
. Do not mow
over property stakes or other metal posts. Such objects
could damage the blade or be accidentally thrown by the
mower in any direction and cause serious personal injury
to the operator and others.
• For a healthy lawn, always cut off one-third or less of the
total length of the grass.
• When mowing large areas, start by turning to the right so
that clippings will discharge away from shrubs, fences,
driveways, etc. After one or two rounds, mow in the
opposite direction, making left hand turns until finished.
• Mow so that discharged clippings exit in the direction of
the lawn area that has already been cut.
• When cutting heavy grass, reduce speed to allow for more
effective cutting and a proper discharge of the clippings.
• During normal mowing, cut only about 1.5" of the grass
blade. Cutting more than that is not recommended unless
grass is sparse or it is the end of the mowing season.
• Do not cut wet grass. It will stick to the underside of the
deck and prevent proper bagging or mulching of grass
clippings.
• New or thick grass may require a narrower cut or a higher
cutting height.
• Keep the mower deck and side discharge chute clean.
Remove grass clippings, leaves, dirt, and any other
accumulated debris before and after each use. Do not
spray with a garden hose to clean.
NOTE
Always stop mower, allow blades to completely stop,
and remove the start key before cleaning underneath the
mower.
8.2.9 SLOPE OPERATION
Slopes are a major factor related to loss of control and tip-
over accidents, which can result in severe injury or death.
Operation on all slopes requires extra caution. If you cannot
back up the slope or if you feel uneasy on it, do not mow it.
• Travel in the manufacturer recommended direction on
slopes. Use caution while operating near drop-offs.
• Do not operate machine under any condition where
traction, steering, or stability is in question. Tires could
slide even if the wheels are stopped.
• Always keep the machine in gear when going down
slopes. Do not coast downhill.
• Mow up and down slopes, not across.
• Watch for holes, ruts, bumps, rocks, or other hidden
objects. Uneven terrain could overturn the machine. Tall
grass can hide obstacles.
• Do not mow near drop-offs, ditches or embankments. The
machine could suddenly roll over if a wheel goes over the
edge or if the edge caves in.
• Choose a low ground speed so you will not have to stop
or shift while on a slope.
• Do not mow on wet grass. Tires may lose traction.
• Avoid starting, stopping, or turning on a slope. If the tires
lose traction, disengage the blade(s) and proceed slowly
straight down the slope.
• Keep all movement on slopes slow and gradual. Do not
make sudden changes in speed or direction, which could
cause the machine to roll over.
• Use extra care while operating machine with attachments;
they can affect the stability of the machine. Do not use on
steep slopes.
• If using the optional bagger kit, use extreme caution and
operate the mower slowly when operating on slopes, as
the bagging kit can change the stability of the mower.
• Always use the brakes when travelling down the slope.
Do not attempt to let the mower coast downhill in neutral.

11 MAINTENANCE
Regular maintenance is the best prevention for costly
downtime or expensive, premature repair. The following
pages contain suggested maintenance information and
schedules which the operator should follow on a routine
basis. For more detailed information, refer to the website for
your unit. Remain alert for unusual noises, as they could be
signaling a problem. Visually inspect the machine for any
abnormal wear or damage.
11.1 TIRES
It is important for level mowing that all tires have the correct
amount of air pressure. The recommended pressure are:
NOTE
Tire pressure should only be measured or adjusted when
tires are cold.
Drive wheels 8 psi
Front caster wheels 24 psi
NOTE
Inspect the tires daily. Replace immediately if damaged.
WARNING
Check the tire pressure carefully while inflating. T
oo much
air in the tire could cause the tire to burst, causing serious
personal injury
.
11.2 MOWER BLADE MAINTENANCE
Check the mower blades daily. They are the key to power
efficiency and well-groomed turf. Keep them sharp -- a dull
blade will tear rather than cut the grass, leaving a brown
ragged top on the grass within a few hours. A dull blade also
requires more power
. Replace any blade that is bent, cracked
or broken.
WARNING
Never attempt to straighten a bent blade by heating, or weld
a cracked or broken blade as the blade may break and cause
serious injury. Replace worn or damaged blades.
WARNING
Never work with blades while key is in the ignition switch.
Turn key to “OFF” position, remove key from switch and
disconnect battery cables by pulling inward on RED battery
quick disconnect handle in battery box compartment. Block
up mower when you must work under it. W
ear gloves when
handling blades. Always check for blade damage if mower
strikes a rock, branch or other foreign objects!
DANGER
The blade adapter will come off when the blade cap screw
is removed. Touch-up sharpening can be done with a file.
Check the blades for balance following grinding. A
commercial balancing tool is available through most
hardware supply stores, or balancing can be done by placing
the blade on an inverted line punch or 1/2" bolt. Blade
should not lean or tilt. While spinning the blade slowly, it
should not wobble. If blade is out of balance, true it up
before reinstalling. Lay the blade on a flat surface and check
for distortion. Replace any distorted blade.
WARNING
•
The blade sail (curved part) must be pointing upward
toward the inside of the deck to ensure proper cutting.
• When mounting blades, rotate them after installation to
ensure blade tips do not touch each other or sides of the
mower
.
• Failure to correctly torque the bolt may result in the loss
of the blade, which can cause serious injury.
• Mower blades are sharp and can cut. Wear gloves and
use extra caution when servicing them.
11.2.1 REPLACE THE BLADE
Blade

asher
Bolt
1. Stop the motor, remove the start key, and set the parking
brake.
2. Raise the height of the cutting deck to its highest position
to allow access to blades.
NOTE
If necessary, raise the mower by placing on a lift or
using a jack and jack stands, or remove the cutting deck
as described in the previous section to gain access to the
blades.
WARNING
If raising the mower to access the blades, make sure the
mower is properly secured and the parking brake is set
before proceeding. Failure to properly secure the mower
could cause it to fall, resulting in death or possible
serious personal injury.
3. Wedge a block of wood between the blade and mower
deck to prevent the blade from turning.

, blade insulator, and blade.
6. Thread the blade nut on the shaft and finger tighten.
7. Torque the blade nut down clockwise using a torque
wrench (not provided) to ensure the bolt is properly
tightened. The recommended torque for the blade nut is
796~885 in. lbs.
WARNING
Ensure blade is properly seated and the blade nut is
tightened to the torque specifications above. Failure to
properly attach the blade could cause it to come loose
and result in possible serious personal injury.
8. Repeat with second blade, if needed.
NOTE
Make certain all parts are replaced in the exact order in
which they were removed.
11.3 REPLACE THE HEADLIGHT

11.5 TORQUE VALUES
WARNING
Particular attention must be given to tightening the drive
wheel lug nuts and blade spindle bolts. Failure to correctly
torque these items may result in the loss of a wheel or blade,
which can cause serious damage or personal injury.
Torque values are given below:
Part Ft-lbs. Nm
Wheel (lug) nuts 89 120
Blade spindle bolt 66 90
Lug nuts only -It is recommended that these be checked after
the first 2 hours of operation, initially, every 100 hours and
following removal for repair or replacement.
For all other torques refer to the various mower parts manuals
for standard torque chart.

1.6 BATTERY PACK MAINTENANCE
Your Greenworks mower is powered by a battery pack which,
when maintained properly, will provide years of useful life.
For proper care, adhere to the following instructions:
•
Always charge batteries after each use.
• Whenever a battery pack is fully discharged and turned
off, it is best to recharge the battery as soon as possible.
Over-discharge of the battery pack means the battery life
will be shortened and the battery may become
permanently damaged. There is no need to fully charge; it
will be beneficial even if you only charge the battery pack
for 5-10 minutes. It is best to recharge it within 24 hours.

• Check that battery cables are securely tightened to
batteries each time you service the battery.
•
Keep grass, dirt and debris from collecting near battery
terminals and in battery area.
• Charge batteries indoors in a well-ventilated and dry
location away from sparks or flames. Never expose
charger to rain, vapor or liquid.
• Charge only lithium batteries provided by Greenworks.
• Do not touch uninsulated portion of charger (terminal
pins) or of output connector.
• Do not use with defective cords and wires. Replace
defective cords and wires immediately.
• For long-term storage, please make sure the storage
temperature is -4°F - 113°F within one month, and 32°F -
95°F between two and 12 months.
• The working environment of the battery pack is 14°F -
113°F. Battery pack can be used a -5°F - 131°F for

• Use a stick or similar instrument to clean under the
mower, making sure that no part of the body -- especially
arms and hands -- is under mower.
• Keep your machine clean and remove any deposits of
trash and clippings.
• Keep battery compartment, deck and operator’s station
clean of accumulated trash, grass clippings, and other
debris.
•
Clean battery compartment, drive motor compartment,
mower deck, seat, etc., of all dirt and debris. T
o clean, use
only compressed air. DO NOT use water, solvents, hard
cleaners or abrasives.
• Always wear adequate eye protection when servicing the
batteries or when grinding mower blades and removing
accumulated debris. Never attempt to make any
adjustments or repairs to the mower’s drive system,
mower deck or any attachment while the traction drive
system is running. Repairs or maintenance requiring
power should be performed by trained maintenance
personnel only.
• Never work under the machine or attachment unless it is
safely supported with jack stands. Make certain machine
is secure when it is raised and placed on the jack stands.
• The jack stands should not allow the machine to move
when the traction drive system is running and the drive
wheels are rotating. Use only certified jack stands. Use
