Always maintain a safe distance from people and pets when mowing.
Always stop machine if someone enters the area.
Avoid injury. Keep area clear of bystanders when engaging deck blade switch.
Always operate machine in daylight or with adequate working lights.
Follow daily and weekly checklists, making sure electrical connections are secured and
bolts are tightened. Always observe traffic laws while driving machine from
one location to another. Watch for traffic when operating near or crossing roadways.
Always be alert for hazards such as rocks, metal objects and other debris which may be
thrown or entangled by mower blades. Watch out for holes or deep depressions.
Inspect area to be mowed for hazards such as rocks, metal objects and other debris which
may be thrown or entangled by mower blades. Remove these objects before mowing.
Always inspect machine for damage after striking a foreign object. If damage is found,
repair machine immediately. Be sure to stop on level ground, disengage deck blade
switch, place drive control bars in neutral position, turn key to OFF position,
remove key and disconnect battery cables by pulling inward on RED battery quick disconnect handle in battery
box compartment! Always wear adequate ear protection, such as earplugs, when operating this
equipment as prolonged exposure to uncomfortable or loud noises can cause impairment
or loss of hearing. Do not wear radios or music headphones while operating the machinery.
Safe operation requires your full attention.
Do not operate the equipment while wearing sandals, tennis shoes, sneakers, shorts or
any type of loose fitting clothing. Long hair, loose clothing or jewelry may get tangled in
moving parts. Always wear long pants, safety glasses, ear protection and safety shoes when
operating this machine.
Always wear safety goggles or safety glasses with side shields when operating the mower.
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.
When moving in reverse, SLOWLY pull right and left Drive Control Levers rearward and avoid sudden
movement. Rapid movement of the Drive Control Levers in either direction
could result in a reaction of the machine that can cause serious injury.
Never operate a poorly maintained machine.
Never attempt high speed maneuvering, especially in crowded, congested areas or on slopes.
Never allow persons to operate this machine without proper instruction or allow children to
operate machine. Allow only responsible adults who have read and understand
these instructions to operate this machine.
Never put hands or feet under any part of the machine while it is running.
Never carry passengers.
Never direct discharged material toward anyone. Avoid discharging material against
a wall or obstruction. Material may ricochet back toward the operator. Always disengage
the blades and wait for them to stop before crossing gravel drives, walks or roads.
Always keep clear of the mower blades and attachments during their operation.
Turn off blades when not mowing.
10
Slow down before turning.
Turn the key to the OFF position, remove key and disconnect battery cables by pulling inward on RED battery
quick disconnect handle in battery box compartment before removing the grass catcher or unclogging the
discharge chute. Never clear the discharge chute with the machine running. Turn
the key to the OFF position, remove key, and make sure the blades have stopped before cleaning.
Use a stick to clear a plugged discharge area. Never use your hand!
Do not operate the machine while under the influence of alcohol or drugs.
Exercise caution when loading or unloading the machine onto a trailer or truck.
Data indicates that operators, age 60 years and above, are involved in a large percentage
of mower-related injuries. These operators should evaluate their ability to
operate the mower safely enough to protect themselves and others from serious injury.
If any attachment or additional weight is mounted on the rear or side of the unit (depending on
model), any rapid movement in either direction could result in a reaction of the machine
that can cause serious injury.
Clean flammable material from machine. Prevent
fires by keeping battery compartment, deck and operator’s
station clean of accumulated trash, grass clippings,
and other debris.
Using a ramp
Use extreme caution when loading and unloading a unit onto a truck or trailer with a ramp.
Use only a single, full width ramp; do not use individual ramps for each side of the unit.
Having a full width ramp 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. When on a ramp avoid sudden acceleration.
NOTE: To lock deck height in highest position for travel 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 next pull rearward on Deck
Height Locking Handle with other hand; proceed to lower Deck Height Adjustment Handle to desired
height. **See Fig.14 Page 19**
Slope operation (see page 12A)
Slopes are a major factor in loss-of-control and tip-over
accidents, which can result in severe injury or death. All
slopes require extra caution. If you cannot back up the slope
or if you feel uneasy on it; do not mow it. REMINDER: Only
operate on slopes of 15 degrees or less.
Use extreme caution when operating on slopes.
• Be extremely careful changing directions on a slope.
Slow down.
• Do not operate where the machine could slip or tip.
• Turn slowly
• Turn on the most level part of the slope
• To maximize traction, it is better to turn the front of the
machine uphill, rather than downhill. If drive tires lose
traction, steering control is lost which could cause
serious injury or death.
• If it becomes necessary to turn downhill, turn slowly
and gradually.
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, 3.05 meters)
away from drop-offs, retaining walls, drainage ditches,
11
embankments, water, and other types of hazards to avoid
a wheel dropping over the edge or to avoid the ground
from breaking away. This will reduce the risk of the
machine suddenly rolling over causing 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
and serious injury or death.
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.
Do not try to stabilize the machine by putting your foot
on the ground.
If the mower’s tires lose traction when operating on
slopes, disengage the deck blade switch, place the drive control levers
in the neutral position, and 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 Mean Green 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, page 12A 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; i.e. holes, ruts, washouts
3. Mounds of dirt
4. Soil type; i.e. sand, loose dirt, gravel, clay
5. Grass type, density, and height
6. Extremely dry conditions of grass
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 3.05 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
12
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:
1. Water; i.e. lake, river
2. Cliffs, retaining walls
3. Roads, highways
4. Buildings
5. Rocks
These are just a few examples of situations when caution
must be used when operating on a slope. There are
many other possibilities too numerous to mention. Just
remember to always exercise extreme caution when operating
on any slope.
Children
Tragic accidents can occur if the operator is not alert to 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.
Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended.
Always disengage deck blade switch & turn key to OFF position and
remove key. Keep children out of the mowing area and under the watchful care of
a responsible adult other than the operator. Be alert and turn the machine off if children enter the area. Before and
while backing, look behind and down for small children.
Never carry children, even with the blades 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. Never allow children to operate the machine.
Use care when approaching blind corners, shrubs, trees, the end of a fence or
other objects that may obscure vision. Never allow children or others in or on towed equipment.

4. Rotate key in Master Power Ignition Switch counter clockwise to the OFF position.
Driving the 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 drive control levers in either
direction could result in a reaction of the machine that
can cause serious injury.
After turning master key to ON position:
To go forward, push both Drive Control Levers forward an equal distance
To go in reverse, pull both Drive Control Levers rearward an equal distance
To turn left, move the right Drive Control Lever farther
forward from neutral than the left Drive Control Lever.
To turn right, move the left Drive Control Lever farther
forward from neutral than the right Drive Control Lever.
Zero radius turn, move one Drive Control Lever forward
and the other Drive Control Lever back of neutral. This will
allow the drive wheels to counter-rotate.
To stop or decrease speed: To stop, move both Drive Control Levers to
neutral, middle position.
When going forward and want to decrease speed,
pull back gently on both Drive Control Levers. When going in reverse and want to
decrease speed, push forward gently on Drive Control Levers.
For an emergency stop:
Release both Drive Control Levers. This will disengage drives, blades and engage brakes.
Any sudden movement could cause the front of the mower to come off of the ground resulting in
possible loss of control causing serious injury or death.
Turn the master ignition key to the OFF position. This will shut
down the traction drive system and the deck blade system.
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 Drive Control Levers
is not recommended as damage to the electric system components
may occur.
To increase speed, increase the Drive Control Levers distance
from neutral. The farther forward the Drive Control Levers are
from neutral, the faster the machine will travel forward. The
farther back the Drive Control Levers are from neutral, the faster
the machine will go in reverse. Also changing the Drive Speed Control Knob (Fig.3F Page9)
will increase or decrease the speeds of mower in forward, reverse and turning.

EXECUTING AN END-OF ROW ZERO TURN
Your Stand On Mower’s unique ability
to turn in place allows you to turn around at
the end of a cutting row rather than having
to stop and Y-turn before starting a new
row.
To execute a left end-of row zero turn:
1. Slow down at the end of the row.
2. Move the RIGHT drive control
lever forward slightly while
moving the LEFT drive control
lever back to center and then
slightly back from center.
3. Begin mowing forward again.
THIS TECHNIQUE TURNS THE MOWER
LEFT AND SLIGHTLY OVERLAPS THE ROW
JUST CUT – ELIMINATING THE NEED TO
BACK UP AND RE-CUT MISSED GRASS.
Remember: The more you practice, the
better your control of the stand on
mower!

Operating suggestions
DANGER: Prior to operating the mower 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 normal
speed operation. An inexperienced operator should not
mow on slopes or on uneven terrain and should always mow
in Slow Drive Speed.
WARNING: If you lose steering control while operating
the machine on a slope, release both Drive Control Levers. This will disengage drives and blades and engage
the brakes. Turn key to OFF position.
Call your Mean Green Mower Dealer to resolve problem before continuing to operate.
WARNING: The unit’s steering control levers are
very responsive: Easy does it! For smooth operation,
move controls slowly, avoid sudden movement. 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 over-steer and
lose control. Slow-moving, slow speed practice maneuvers are
recommended to become familiar with these characteristics before attempting high 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
which 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 blade switch
in the disengaged position, place steering control
levers in the neutral position and turn key to the
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. Wear gloves
when handling blades. Always check for blade damage if mower strikes a rock, a
branch or another foreign object during mowing!
Direct grass discharge to right (with side discharge models),
away from un-mown area. Select a mowing pattern that directs grass discharge
towards the outside, not towards center, of mowing area. Generally, this
means using a pattern utilizing left turns because side discharge
is to right. In any case, avoid throwing grass discharge onto
un-mowed area because grass is then mowed “twice”. Mowing
16
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; 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.
WARNING: Never direct discharge of material from
mower deck towards bystanders. Do not operate the
mower without the discharge chute (Fig.4D)(with side discharge models).

Anti-scalp wheels (Fig.15)
Anti-scalp wheel kits are standard on Mean Green Mower 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, in 1/2”
increments, using the different axle mount holes in the wheel mount bracket. (if applicable on model)

Regular 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 order the correct parts manual for your unit.
Remain alert for unusual noises, they could be signaling a
problem. Visually inspect the machine for any abnormal wear or
damage. A good time to detect potential problems is while
performing scheduled maintenance service. Correcting the
problem as quickly as possible is the best insurance.
Daily inspect mower for grass clippings and wire and string
tangles. The underside of the mower deck may collect a buildup
of grass clippings and dirt, especially when grass is wet or
has high moisture content. This build-up will harden, restricting
blade and air movement and will probably show a poorer quality
of cutting. Therefore it should be removed routinely.
To do this it will be necessary to raise and block the deck,
using jack stands or blocks, in the full up position and scrape the
build-up from underneath.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled personnel.
Consult Mean Green Mower Dealer when assistance is needed.
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. Call your Mean Green Mower Dealer for assistance.

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 which 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.
DANGER: Never work with blades while key is in

Mower blade removal
Use a 9/16” wrench or socket to remove the 3/8” cap screw
holding the blade to the motor shaft from underneath. It may be
necessary to use a 1-1/4” channel lock pliers to keep the blade adapter from
turning while removing blade cap screw.
NOTE: 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.
Spin the blade slowly, blade 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.
Mower blade installation
Do not re-use spindle bolts which have stripped, worn or
undercut threads.
Make sure that the blade adapter is seated properly on the
blade motor shaft before tightening the blade cap screw. Use a 9/16”
socket with a torque wrench to re-attach the blade to the
motor shaft from underneath. It will be necessary to use a 1-1/4”
channel lock pliers to keep the blade adapter from turning. Torque cap
screws on motor shafts to 50 foot-pounds (67.8 Nm) when
reinstalling blades.
IMPORTANT: The blade sail (curved part) must be pointing
upward toward the inside of the deck to ensure proper cutting.
IMPORTANT: When mounting blades, rotate them after
installation to ensure blade tips do not touch each other or sides

(Fig.10)
IMPORTANT: ALWAYS LEAVE BATTERY COVER
IN THE OPEN POSITION THROUGHOUT CHARGING TIME. NEVER CHARGE WHEN CLOSED!!
5. Allow 1-12 hours for a full battery charge (depending on battery charger option).
The green light indicates batteries are Fully Charged OR the red LED indicator will read 0.00
Amps. Leaving batteries on charger longer than 12 hours does not harm the batteries. The charger will
not overcharge batteries.
6. When ready to use mower again after charging, always turn charger OFF before
disconnecting charger from mower. Disconnect charger cord from wall outlet then from the mower.
7. Close back battery cover. (Fig. 8A pg.27) Note: Be sure charger is positioned where
air can flow unrestricted into and out of charger.
Charging Recommendations:
WARNING: Do not smoke while servicing the batteries.
WARNING: Always wear safety glasses and protective
clothing near battery. Use insulated tools.
1. Lithium Modules do not develop a memory and need not be fully discharged before recharging. 2. Over the
winter season, when mower is not used regularly, the charger can
be kept plugged into the mower to maintain a full charge on the batteries. Batteries left
uncharged will slowly discharge. Before initial use each spring season, be sure batteries have
a full charge before mowing. 3. If charger is not left plugged in, the batteries should be
fully charged every 30 days to maintain battery life. 4. When charging, be sure charger cooling
fan inlet and outlet are not blocked.

Battery Storage
To maximize battery life it is best to fully charge batteries shortly after each use. The Mean Green Mower charger
is designed to remain plugged into the vehicle and turned ON during storage. If the charger remains on and
connected, it will automatically maintain the charge level of the battery pack. All batteries self-discharge over
time. NOTE: If the mower cannot remain plugged in and on charger then it is required that the battery
pack be charged for a minimum of 12 hours every 30 days. Failure to maintain the battery charge level will
void the battery warranty.
TROUBLESHOOTING
SYMPTOMS & PROBABLE CAUSES
SUGGESTED REMEDIES
FOR ANY ELECTRICAL PROBLEMS
****RESET Mower Electronics by Switching Ignition Key to OFF position for approximately 5
seconds & then back to ON position.******
Mower blades stop while mowing
When battery voltage becomes low, the mower blades will stop, although the drive
motors will continue to run enabling driver to continue to drive unit. When the batteries
discharge to this point they require recharging. The unit should immediately be
returned to the battery charging area and the unit connected to the battery
charger.
Uneven cutting height
The blade(s) are not sharp. Sharpen the blades.
A cutting blade(s) is/are bent. Install new cutting blade(s).
The deck is not level - Contact your Mean Green Products Dealer.
The underside of the deck is dirty. Clean the underside of the deck.
Tires improperly inflated. Adjust air pressure to proper psi (see pg.23)
31
A blade spindle is bent. Contact your Mean Green Products Dealer.
Loss of deck operation
The deck fails to operate with fully charged batteries.
RESET Mower Electronics by Switching Ignition Key to OFF position for approximately
5 seconds & then back to ON position. If this does not remedy the problem - Contact
your Mean Green Mower Dealer.
Mower will not start
Check that key is in the ON position.
Check all battery connections in back battery compartment.
Make sure batteries are charged.
Check to see that ALL circuit breakers are not tripped.
Mower blades stop due to low charge & mower will not move
Turn blades off, turn key to OFF position, wait approximately 5 seconds and then back
to ON(this resets computer)
If manual operation is needed to return to charging station or to move mower without
battery power, pull both Emergency Drive Brake Release Levers INWARD to release
drive brakes (located behind electronics bay cover and operator knee cushion and at
the end of each drive motor (2 each levers SEE Page 20 Fig.6A & 6B) and push or
tow mower slowly.
