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.
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.

SAFETY INFORMATION
•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.
USING 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.
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.
BATTERY & CHARGER
CAUTION
Use only Greenworks Commercial approved replacement batteries, as other batteries may cause
injury or damage to the mower. Only to be used with Greenworks Commercial 82V Batteries.
BATTERY SAFETY RULES
•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.

10
•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, battery 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.
•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. Useinsulated 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 toolsto 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.

SAFETY START INTERLOCK SYSTEM
The machine is equipped with a safety start interlock system consisting of the park brake switches, seat
switch, and deck 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.

WARNING
Do not operate the mower with the ROPS folded (lowered position) -- a standard operating mode. Afolded
ROPS does not provide rollover protection.
WARNING
Always wear your seat belt unless the ROPS is folded down. In this case, the seat belt should never be
worn.
WARNING
To minimize chance of injury or death from rollover:
Keep ROPS in the raised and locked position and use the seat belt.
Never operate machine on a slope with the ROPS folded down (lowered position).
There is no rollover protection when the ROPS is in the lowered position.
Lower the ROPS only when absolutely necessary.
Drive slowly and carefully. Raise the ROPS as soon as clearance permits. Read and follow slope
operation instructions and warnings.
Do not wear seat belt when the ROPS is in the lowered position.
WARNING
Always pull from the tractor hitch. Do not attach chains or ropes to the ROPS for pulling purposes, as
the machine can tip backwards.
Always fasten seat belt during operation of the machine (mower equipped with ROPS in “raised/up”
position).

ANTI-SCALP WHEELS (See Figure 7)
Anti-scalp wheel kits are standard on Greenworks Commercial units. These anti-scalp wheels
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).

•Remove the neutral bypass from its original location and install it to the motor. Operate one or both
of the knobs on the motor, as needed.
•Rotate the neutral bypass knobsclockwise to release drive brakes; counterclockwise to engage.
• Install the neutral bypass knob(s) back to its/their original location after completing maintenance.
WARNING
Never drive mower with the neutral bypass knob working. Always install the neutral bypass knob to
the original position before driving! Failure to re-install the knob could cause serious damage to your
mower and void mower warranty!

OPERATING YOUR LAWN MOWER
STARTING YOUR MOWER
WARNING
Seat belt must be fastened while operating a mower equipped with ROPS in the raised and secured
position. Do not wear the seat belt when the ROPS is in the lowered position.
•With key inserted, turn master power ignition switch on by rotating key clockwise to the ON position.
•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.
•Pull right and left drive control levers inward until stops are contacted.
•Pull up on deck blades ON/OFF switch to start cutting blades for mowing. NOTE: only engage blades
when drive control levers are in the NEUTURAL position! NEVER engage blades when moving!!
•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.
STOPPING YOUR MOWER
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.
• Return drive control levers to the Neutral/Park brake position.
• Push down on deck blades ON/OFF to turn off the blades.
• Push drive control levers outward into park brake position.
• Rotate key in Master Power Ignition Switch counterclockwise to the OFF position.
DRIVING THE MOWER (See Figure 10)
After starting the traction drive system, engage the steering control levers and steer as follows:
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.

OPERATING YOUR LAWN MOWER
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. (See Figure 10)
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.
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.
IMPORTANT
Rapid movement of steering control levers is not recommended as damage to the electrical
system components may occur.
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.
STEERING CONTROL LEVER ADJUSTMENT (See Figure 11)
The steering control levers can be adjusted for operator comfort. By loosening the cap screws that attaches
the upper control lever to the lower lever,the upper control lever can be pivoted to fit the operator’s
personal preference. The steering control levers should be adjusted so that they align with each other when
in the neutral position.
