traction and no holes, drop-offs, 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.
3
English EN
P0802465-00 v1.2

• 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.
• Disengage blade(s) when not mowing. Shut off engine
and wait for all parts to come to a complete stop before
cleaning the machine or unclogging the discharge guard.
• If lawnmower strikes a foreign objects, 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 the machine before servicing or removing blade.
•Do not reach under blade guard. Keep hands, feet, and
clothing way from rotating blades.
• To reduce risk of injury to persons, remove battery pack
when not in use.
• 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.
• Remove or disconnect battery before servicing, cleaning
or removing material from lawnmower.
2.6 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.
•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.
• 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.
• Always keep the machine in gear when going down
slopes. Do not shift to neutral and coast downhill.
• 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.
• Do not try to stabilize the machine by putting your foot
on the ground.
• 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.
2.7 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.
4
English
EN
P0802465-00 v1.2

• 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.
• 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.
2.8 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
off 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.
2.9 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.
2.10 BATTERY AND CHARGER
• Do not recharge batteries in a confined or unvented area.
• Do not smoke, strike a match, or cause a spark in the
vicinity of the battery during charging.
• Store indoors, and do not expose to rainwater. Avoid
storing in direct sunshine.
• Do not charge batteries in rain or in wet location.
• Double insulation - When servicing, use only identical
replacement parts.
• Only to be used with Greenworks Commercial 82V
Batteries (2919002). See Parts Manual.
• Electrical maintenance should be performed by trained
professionals ONLY
2.10.1 BATTERY
• Battery-operated mowers and tools do not have to be
plugged into an electrical outlet; therefore, they are
always in operating condition. Be aware of possible
hazards when not using your battery-operated mower or
when changing accessories. Following this rule will
reduce the risk of electric shock, fire, or serious personal
injury.
• Do not place battery-operated machines or tools -- or the
batteries themselves -- near fire or heat. This will reduce
the risk of explosion and possibly injury.
• Do not crush, drop or damage battery pack. Do not use a
battery pack or charger that has been dropped or received
a sharp blow. A damaged battery is subject to explosion.
Properly dispose of a dropped or damaged battery
immediately..
• Batteries can explode in the presence of a source of
ignition, like a pilot light. To reduce the risk of serious
personal injury, never use any cordless product in the
presence of an open flame. An exploded battery can
propel debris and chemicals. If exposed, flush with water
immediately. Do not charge battery tool in a damp or wet
location. Following this rule will reduce the risk of
electric shock.
• For best results, your battery-operated machine should be
charged in a location where the temperature is more than
0°C (32° F) but less than 45°C (113° F). To reduce the
risk of serious personal injury, do not store outside or in
vehicles.
• Under extreme usage or temperature conditions, batter y
leakage may occur. If this liquid comes in contact with
your skin, wash immediately with soap and water. If
liquid gets into your eyes, flush them with clean water for
at least 10 minutes, then seek immediate medical
attention. Following this rule will reduce the risk of
serious personal injury.
• 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 sparks, burns, or a fire.
• Battery posts, terminals, and related accessories may
contain lead and lead compounds, chemicals known to
the State of California to cause cancer and reproductive
harm. Wash hands after handling.
5
English EN
P0802465-00 v1.2

• Charge batteries in an open, well-ventilated area away
from spark and flames. Unplug charger before connecting
or disconnecting battery to/from the charging port.
Always wear safety glasses and protective clothing/gear.
Use insulated tools.
• Sparks can cause a battery gas explosion, which will
result in serious personal injury. Prevent the battery
terminals from touching any metal mower parts when
removing or installing the battery. Do not allow metal
tools to short between the battery terminals and metal
mower parts. Use insulated tools. Always keep protective
battery cover and rear cover in place.
• Explosive gases from batteries can cause serious injury,
or death. Poisonous battery fluid contains sulfuric acid;
contact with skin, eyes or clothing can cause severe
chemical burns.
• Follow first aid directions for contact with battery fluid.
Get medical attention immediately.
• Incorrect battery cable routing could cause damage to the
mower and battery cables. This can cause sparks, which
can cause a battery gas explosion that will result in
serious personal injury.
• Do not open or mutilate the battery. Mutilated batteries
can release corrosive electrolytes which can cause
damage to the eyes or skin. It may be toxic if swallowed.

blades ON and OFF switch.
The mower’s safety start interlock system is also designed to
protect the operator and others from accidental injury due to
unintentional traction drive system starting.
Check mower safety start interlock system daily, prior to
operation. This system is an important mower safety feature.
It should be repaired immediately if it malfunctions. Call
Greenworks Commercial immediately. The machine
incorporates a separate seat switch which will stop the drive
system and deck motors when the operator is unseated for any
reason while the mower is operating. This is a safety feature
designed to prevent runaway or accidental entanglement.
WARNING
The safety interlock system must not be disconnected or
bypassed. Doing so could cause the machine to operate
unexpectedly, resulting in personal injury.
To inspect the system:
1. The operator must be on the seat when testing the seat
switch.
2. Turn the master power ignition switch to the ON position
with key.
3. Keep steering control levers in neutral position.
4. Pull the deck blades ON and OFF switch to engage the
motor.
5. Slowly raise off of the seat. The deck blade system should
stop.
6. If the deck blade system fails to stop when the operator is
off of the seat and if the cause cannot be
determined,contact your Greenworks dealer immediately.
7.4 ANTI-SCALP WHEELS
Anti-scalp wheel kits are standard on Greenworks
Commercial units. These anti-scalp wheels (19) are designed
to minimize scalping when mowing on rough, uneven terrain.
After setting the cutting height, adjust the anti-scalp wheels
so they extend below the deck but do not contact the ground.
They should always be at least 1/4" to 3/4" below the deck.
With the unit sitting on a flat level surface, the wheel position
can be adjusted up or down as needed from 3/4" to 1-3/4"
below the blade surface. Move the wheels up or down - using
the different axle mount holes in the wheel mount bracket (if
applicable on model).

7.5 NEUTRAL BYPASS KNOB
1. Locate the Neutral Bypass Knobs behind the frame at the
rear of the mower.
2. Remove the (4) thumb screws (24) holding in the mesh
cover.
3. Remove the neutral bypass knob from its original location
and install it to the motor (25). Operate one or both of the
knobs on the motor, as needed.
4. Rotate the neutral bypass knobs (26) clockwise to release
drive brakes; counterclockwise to engage.
5. Install the neutral bypass knob(s) (26) back to its/their
original location after completing maintenance.

or loading/unloading – Pull Deck Height Adjustment
Handle completely rearward until handle locks in highest
position. To lower deck from highest position – pull
rearward on Deck Height Adjustment Handle with one hand
until rearward on Deck Height Locking switch to the
position, proceed to lower Deck Height Adjustment Handle
to desired height.
8.2 OPERATE THE MACHINE
8.2.1 START THE MACHINE
1. With key inserted, turn master power ignition switch on
by rotating key clockwise to the ON position.
2. Check for the appropriate speed mode by pressing drive
speed control button to “low speed” position.
NOTE
It is always recommended to start out in low mode/slow
speed.
3. Pull right and left drive control levers inward until stops
are contacted.
4. Pull up on deck blades ON/OFF switch to start cutting
blades for mowing.
10
English
EN
P0802465-00 v1.2

NOTE
Only engage blades when drive control levers are in the
NEUTURAL position! NEVER engage blades when
moving!!
5. Push drive control levers forward for forward motion and
pull for reverse motion.
NOTE
Electric brake will engage after drive control levers are
returned to neutral.
8.2.2 DRIVE THE MACHINE
After starting the traction drive system, engage the steering
control levers and steer as follows:
WARNING
Always be aware of what is behind the machine before
backing up. Do not mow in reverse unless absolutely
necessary. Always look down and behind before and while
backing up.
WARNING
Rapid movement of steering control levers is not
recommended as damage to the electrical system
components may occur.
•To go forward, push steering control levers forward an
equal distance.
•To go in reverse, pull steering control levers rearward an
equal distance.
•To turn left, move the right steering control lever farther
forward from neutral than the left steering control lever.
•To turn right, move the left steering control lever farther
forward from neutral than the right steering control lever.
•To execute a zero-radius turn, move one steering
control lever forward and the other steering control lever
back of neutral. This will allow the drive wheels to
counter-rotate.
•To stop or decrease speed, move steering control levers
to neutral. When going forward, pull back gently on
steering control levers. When going in reverse, push
forward gently on steering control levers.
•For an emergency stop, there are two methods that can
be used:
• When traveling forward or in reverse, place the
steering control levers in the park brake position
immediately. When moving in the rearward direction,
push forward gently on steering control levers and
avoid sudden movement. Any sudden movement
could cause the front of the mower to come off of the
ground, resulting in possible loss of control, thereby
causing serious injury or death.
• Turn the ignition key to the OFF position. This will
shut down the traction drive system and the deck
drive system.
•To make a three-point turn to the right, move the left
steering control lever farther forward from neutral than
the right steering control lever and start the turn. Next,
pull back on the steering control levers until they are past
neutral and the machine starts to go rearward. Pull the
right steering control lever farther rearward from neutral
than the left steering control lever until the rear of the
machine has pivoted around. Then, push the steering
control levers forward until they are both past neutral and
the machine starts to go forward. Push the left steering
control lever farther forward from neutral than the right
steering control lever and finish the turn.
•To increase speed, increase steering control lever’s
distance from neutral. The farther forward steering
control levers are from neutral, the faster the machine will
travel forward. The farther back steering control levers
are from neutral, the faster the machine will go in reverse.
8.2.3 STOP THE MACHINE
DANGER
Never make sudden stops or reverse direction, especially
when maneuvering on a slope. The steering is designed for
sensitive response. Rapid movement of the steering control
levers in either direction could result in a reaction of the
machine that can cause serious injury.
1. Return drive control levers to the Neutral/Park brake
position.
2. Push down on deck blades ON/OFF to turn off the blades.
3. Push drive control levers outward into park brake
position.
4. Rotate key in Master Power Ignition Switch
counterclockwise to the OFF position.
8.2.4 OPERATION SUGGESTIONS
DANGER
Prior to operation, the operator should be thoroughly
familiar with the proper use and operation of the equipment,
should read the manual completely and thoroughly, and
should have attempted slow moving maneuvers to become
familiar with the operation of the equipment before
attempting normalspeed operation. An inexperienced
operator should not mow on slopes or on uneven terrain.
11
English EN
P0802465-00 v1.2

WARNING
If you lose steering control while operating the machine,
place the steering control levers in the park brake position
immediately and turn key to the “OFF” position. Inspect the
machine and consult your Greenworks Commercial dealer
to resolve the problem before continuing to operate.
WARNING
The unit’s steering control levers are very responsive. For
smooth operation, move levers slowly, avoiding sudden
movements. Skill and ease of operation come with practice
and experience. The machine can spin very rapidly. Use
caution when making turns and slow down before making
sharp turns.
Inexperienced operators may have a tendency to oversteer
and lose control. Slow-moving practice maneuvers are
recommended to become familiar with these characteristics
before attempting normal-speed operation.
WARNING
Sharp depressions or raised obstacles (such as gutters or
curbs) should not be directly approached at high speed in an
attempt to “jump” them as the operator could be thrown
from the equipment. Approach at a slow speed and angle
one drive wheel at the obstruction. Continue at an angle
until the wheel clears and then pivot the opposite wheel
around.
When turning on soft, wet turf, keep both wheels rolling
either forward or backward. Pivoting on one stopped wheel
can damage turf. This is especially important when mowing.
Keep blades sharp. Many professional mowing companies
have additional sets of blades and change blades twice a day:
once in the morning and again at noon. Many problems with
incorrect cutting patterns are due to dull blades or blades
which have been sharpened incorrectly. Information on
sharpening blades is listed in this manual’s maintenance
section. In addition, most communities have individuals or
companies that specialize in sharpening mower blades. Blade
sharpness should be checked daily.
DANGER
Never work with blades while key is in the ignition switch.
Always place deck clutch switch in the disengaged position,
place steering control levers in the park brake position and
turn key to the OFF position and remove key from switch.
Block up mower when you must work under it. Wear gloves
when handling blades. Always check for blade damage if
mower strikes a rock, branch, or another foreign object
during mowing.
•Direct grass discharge to right, away from unmown
area. Select a mowing pattern that directs grass discharge
towards the outside the mowing area. Generally, this
means using a pattern utilizing left turns because side
discharge is to the right. In any case, avoid throwing grass
discharge onto unmowed area because grass is then
mowed “twice.” Mowing twice puts an unnecessary load
on the unit and reduces mowing efficiency.
•When mowing a lawn for the first time, cut grass
slightly longer than normal to avoid scalping uneven
terrain. When possible, it is best to use the cutting height
that was used in the past. When cutting grass taller than
six inches, you may want to mow the lawn twice to
achieve a better quality of cut.
•During normal mowing, cut only about 1/3 of the grass
blade. Cutting more than that is not recommended unless
grass is sparse or it is the end of the mowing season.
•Alternate mowing direction to keep the grass growing
straight and better dispersion of the clippings.
•Remember, grass grows at different rates at different
time of the year. Mow more often in the early spring to
maintain the same cutting height. As the growth rate
slows in mid summer, mow less frequently. If you cannot
mow at a regular interval, mow at a high cutting height at
first, then mow again two days later at a lower cutting
height.
•Raise the cutting height of the mower if the cutting
width of the mower is wider than the previous mower.
This ensures that uneven turf is not cut too short.
•Raise the cutting height of the mower if the grass if
slightly taller than normal or if it contains a high degree
of moisture. Then mow it again with the cutting height set
lower. If the machine’s forward motion must be stopped
while mowing, a clump of grass clippings may drop onto
your lawn. To avoid this, move onto a previously cut area
with the blades engaged.
•Charge the battery immediately. If battery percentage is
higher than 2% and less than 5%, the maximum drive
speed will be 5.5 mph and the unit will in low blade
mode. If battery percentage is less than 2%, the working
blade will stop automatically. The unit should
immediately be returned to the battery charging area and
the unit connected to the battery charger.
•Allow motors 30-60 minutes to cool down. If drive
motor exceeds programmed temperature, the motor speed
will decrease. If temperature continues to increase, drive
will shut down at a higher programmed temperature.
8.3 SLOPE OPERATION
• Use extreme caution when operating on slopes.
•Do not remove or modify the stabilizer wheels.
• Watch for holes, ruts, bumps, rocks or other hidden
objects. Uneven terrain could overturn the machine. Tall
grass can hide obstacles.
• Remove obstacles such as rocks, tree limbs, etc.
• Keep all movement on slopes slow and gradual. Do not
make sudden changes in speed or direction.
• Avoid starting and stopping on a slope. If tires lose
traction, disengage the blades and proceed slowly straight
down the slope.
• Mow a safe distance (minimum of 10 feet, or 3.05
meters) away from drop-offs, retaining walls, drainage
ditches, embankments, water, and other types of hazards
12
English
EN
P0802465-00 v1.2

to avoid a wheel dropping over the edge or the ground
breaking away. This will reduce the risk of the machine
suddenly rolling over, which could cause either serious
injury or death.
• Use a walk-behind, push mower or hand-held trimmer on
slopes and near drop-offs, retaining walls, drainage
ditches, embankments and water to avoid machine
rollover.
• Do not mow on wet grass. Reduced traction could cause
sliding and loss of steering control.
• Do not tow on slopes. The weight of the towed equipment
may cause loss of traction and control.
• If the mower’s tires lose traction when operating on
slopes, disengage the deck drive, place the steering
control levers in the park brake position, turn the key to
the “OFF” position and get help.
• Never make sudden starts, stops, turns, or reverse
direction, especially when maneuvering on slopes. The
steering is designed for sensitive response. Rapid
movement of the steering control levers in either direction
could result in a reaction of the machine that can cause
serious injury.
• Never stop suddenly while backing down slopes. This
action may result in a reaction of the machine that can
cause serious physical injury.
• The Greenworks Commercial mower is capable of
operating horizontally (traverse) on moderate slopes.
When operating on slopes up to 15 degrees, be aware of
any conditions that may cause the mower drive tires to
lose traction, resulting in a possible loss of control of the
machine. An operator should not operate on a slope until
he is thoroughly familiar with the equipment.
Do not operate on slopes greater than 15 degrees.
Refer to Slope Guide, when determining the degree of
slope to be mowed. It is strongly recommended that the
operator drive the machine off of the slope, using extreme
caution, if any sign of loss of traction is detected. Wait
until the condition that caused the problem is resolved
before attempting to operate on the slope again. Terrain
conditions can affect traction, resulting in possible loss of
control of the machine. Some of the conditions to be
aware of are:
1. Wet terrain
2. Depressions in the ground (e.g., holes, ruts, washouts)
3. Mounds of dirt
4. Certain types of soil (e.g., sand, loose dirt, gravel,
clay)
5. Grass type, density, and height
6. Extremely dry conditions
7. Tire pressure
The attachments mounted to the mower will also affect
the way it handles on a slope. Be aware that each
attachment’s characteristics vary.
Another consideration is to always mow a safe distance
(minimum of 10 feet/3 meters) away from drop-offs,
retaining walls, drainage ditches, embankments, water,
and other types of hazards to avoid a wheel dropping over
the edge or to avoid the ground from breaking away and
always be aware of what is located at the bottom of the
slope. This will reduce the risk of the machine suddenly
rolling over, causing serious injury or death. Extreme
caution should be used when there is a hazard located at
the bottom of the slope. Some examples are: water (e.g.,
lake, river), cliffs, retaining walls, roads, highways,
buildings, rocks.
These are just a few examples of situations where caution
must be used when operating on a slope. There are many
other possibilities too numerous to mention. Remember to
always exercise extreme caution while operating on any
slope.
• The ROPS may minimize chance of injury or death from
rollover. Seat belt must be fastened while operating a
mower equipped with ROPS in the raised and secured
position. Both retaining pins and hair pins must be
installed. Failure to use seat belt with ROPS will result in
serious injury in the event of a rollover.
