When starting, stopping, or adjusting throttle, stand
at least 30 feet to the side of the unit and wheels. DO
NOT put hands, feet, or loose material on wheels or
unit when unit is running.
THROWN HAZARD WARNING! When mowing do not
stand in front of the cutting deck at any time. Do not
point the front of mower at the operator or any other
person while the cutting blades are moving. All
persons must remain 200 feet from the open front
deck of the mower while blades are turning.
When mowing, the operator and all other persons
should remain at least 30 feet to the side or back of
the mower, and at least 200 feet from the front of
the mower.
DO NOT stand on machine while the engine is

Operating Conditions
Lightning can cause severe injury or death. If
lightning is seen or thunder is heard in the area,
DO NOT operate the machine, seek shelter.
ALWAYS check overhead and side clearances
carefully before operation.
Watch for traffic when operating near or crossing
roadways.
Clear the area of objects such as rocks, wire, toys,
etc., which could be thrown by the blades.

8
Check for weak spots on docks, ramps, or floors.
Avoid uneven work areas and rough terrain. Stay
alert for hidden hazards or traffic.
Use care when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.
Dust, smoke, fog, etc., can reduce vision and cause
an accident.
Operate machine only in daylight or good artificial
light.
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 traverse the slope with
adequate traction, or if you feel uneasy about it,
DO NOT mow it.
DO NOT operate on slopes of more than 35 degrees.
The operator and any observers MUST NOT stand
directly below the mower in case the mower were to
slide or roll over. While a rollover is rare, it is
possible in certain conditions. The machine is very
heavy and if it were to roll over a person, it would
likely result in severe injury or death.
When mowing a slope, the best position is at the top
of the slope, looking down at the mower. Certain
situations may require the operator to be at the
bottom of the slope. When in this position, all
persons must be at least 30 feet to the side of the
mower at all times. If the mower must cross the
path of any person downhill from the machine, those
persons should be on level ground, at least 30 feet
back from where the hill transitions above
10 degrees.
If operating from the side or bottom of a slope, the
operator must be aware of what is at the top of the
slope and beyond. There may be steep drop-offs,
bystanders, or other hazardous terrain. The
operator must be able to control the area that is not
within direct sightlines, so that people are not able
to approach the machine without the operator
knowing.
Watch for holes, ruts, bumps, rocks, or other
hidden
objects. Uneven terrain could overturn the machine.
Tall grass can hide obstacles.
It is NOT RECOMMENDED to mow on moist or wet
grass. Tires
may lose traction causing a loss of
control. If the tires lose traction, disengage the
blade(s) and proceed slowly straight down the slope.
Keep all movements on the slope
slow and gradual .
DO NOT make sudden changes in speed or direction,
which could cause the machine to roll over.
DO NOT park on a slope unless absolutely necessary.
When parking on a slope, ALWAYS chock or block
wheels. ALWAYS set parking brake.
Choose a low ground speed to better maintain
traction.
USE CAUTION when mowing 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.
DO NOT bypass transmission or allow transmission
to free-wheel when on a slope.
Fuel
To avoid personal injury or property damage, use
extreme care in handling gasoline. Gasoline is
extremely flammable and the vapors are explosive.
Fuel used should be 87 octane or higher.
RC Mowers recommends 91 octane. See engine
manual for further details.
Ethanol blends must not exceed 10% ethanol.
Higher ethanol content may cause your machine to
run hotter and damage your engine.
Replace fuel cap securely and clean up spilled fuel
before starting engine.
Extinguish all cigarettes, cigars, pipes, and other
sources of ignition.
Use only an approved gasoline container.
NEVER store the machine or fuel container where
there is an open flame, spark, or pilot light such as
on a water or space heater or other appliances.
NEVER fill containers inside a vehicle or on a truck
or trailer bed with a plastic liner.
ALWAYS place containers on the ground away from
your vehicle before filling.
NEVER fuel the machine indoors.
NEVER remove gas cap or add fuel with the engine
running. Allow engine to cool before fueling.
Fuel is highly flammable and its vapors are
explosive. Handle with care. Use only an approved

9
gasoline container with an appropriately sized
dispensing spout.
NO smoking, NO sparks, NO flames.
Remove gas-powered equipment from the trailer
and refuel it on the ground. If this is not possible,
then refuel such equipment with a portable
container, rather than from a gasoline dispenser
nozzle.
Keep the nozzle in contact with the rim of the fuel
tank or container opening at all times until the
fueling is complete. DO NOT use a nozzle lock-open
device.
NEVER overfill fuel tank. Replace gas cap and
tighten securely.
If fuel is spilled on clothing, change clothing
immediately.
Towing/Transporting
Follow the manufacturer’s recommendations for
weight limits for towed equipment and
towing on
slopes.
Ensure fuel tank switch is turned to off position prior
to transport.
NEVER allow children or others in or on towed
equipment.
Only load or unload machine utilizing ramps and/or
trailer equipment rated for at least 1,500 lbs.
Do not transport machine without at least two (2) tie
downs rated for at least 2,000 pounds each.
Tow only with a machine that has a hitch designed
for towing. DO NOT attach towed equipment except
at the hitch point.
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.
Accessories
Use only recommended attachments that are
appropriate to your machine and can be used safely
in your application.
Follow the manufacturer’s recommendation
for
wheel weights or counterweights.
Check the discharge guard frequently and replace
with the manufacturer’s recommended parts when
necessary.
Batteries
Do not jump start mower. Transmitter electronics
may be destroyed.
DO NOT attach external power sources without a
functioning battery installed.
Avoid electric shock. Objects contacting
both battery
terminals at the same time may
result in injury and
unit damage.
DO NOT
reverse battery connections. Reverse
connections may result in sparks which can cause
serious injury. ALWAYS connect positive (+) lead of
charger to positive (+) terminal, and negative (-) lead
to negative (-) terminal.
ALWAYS disconnect negative (-) cable FIRST and
positive (+) cable SECOND. ALWAYS connect positive
(+) cable FIRST, and negative (-) cable SECOND.
Explosive gases from battery can cause death or
serious injury. Poisonous battery fluid contains
sulfuric acid and its contact with skin, eyes or
clothing can cause severe chemical burns.
No flames, No sparks, No smoking near battery.
ALWAYS wear safety glasses and protective gear
near battery. Use insulated tools.
ALWAYS keep batteries out of reach of children.
Battery posts, terminals, and related accessories
contain lead and lead compounds; chemicals known
to the state of California to cause cancer and
reproductive harm. Wash hands after handling.
Service
The use of non-genuine replacement parts or
accessories could adversely affect machine
operation and safety.
Do not change engine governor setting or over-
speed the engine.
Maintain or replace safety and instruction labels as
necessary.
NEVER lower cutting deck unless a positive
mechanical lock is used.
Keep unit free of debris. Clean up oil or fuel spills.
ALWAYS block wheels and know all jack stands are
strong and secure and will hold the weight of unit
during maintenance.
Do not perform work on the machine before wheels
are blocked from rolling, and brake is applied.
NEVER attempt to make any adjustments to unit
while engine is running (except where specifically
indicated). Stop engine, remove key and spark plug
wire, and wait for all moving parts to stop before
servicing or cleaning.
Allow engine to cool before servicing.

10
Release any pneumatic or hydraulic pressure from
components slowly.
ALWAYS keep body and hands away from pin holes
or nozzles which eject hydraulic fluid under
pressure.
Foreign fluid, such as hydraulic fluid, injected into
body can result in gangrene. Such fluid must be
surgically removed within a few hours by a doctor
familiar with this form of injury.
Moving parts can cut or amputate fingers or a hand.
On multiblade mowers, rotation of one blade will
cause all blades to rotate.
NEVER weld or straighten mower blades.
Do not change blades on the machine until wheels
are blocked, key is out, and controller is off.
Mower blades are sharp. Wrap the blade or wear
gloves and use extra caution when servicing them.

REMOTE CONTROL SYSTEM
The Remote Control (RC) System consists of:
• Radio transmitter (controller)
• Radio receiver (inside machine)
• Linear actuators (2)
• Inclinometer
• Optional equipment (such as Gate interface
tools).

14
RADIO TRANSMITTER
The transmitter (see Figure 10)is equipped with a
joystick, pushbuttons, and toggle switches for the
various functions. It runs on a 3.7V rechargeable
battery. The CAN port on the side of the transmitter
is used to charge the internal battery.
Figure 10
Enable Button
The ENABLE button is a built-in safety feature. By
default, the mower will not drive and will not engage
the PTO until the ENABLE button is pressed.
The system will remain in enable mode as long as
there is joystick movement. If no joystick movement
is detected for 10 seconds, the system will time out
and deactivate enable mode. The operator must
press the ENABLE button to reactivate the joystick
and PTO functions.
PTO Toggle
WARNING: Avoid Injury
NEVER approach the machine with the PTO
toggle in the on position.
The PTO toggle switch turns the mower blades on or
off. The PTO switch will turn on the blades only when
in enable mode. If the PTO switch is on when the
ENABLE button is pushed, the system will ignore the
PTO switch. The operator must toggle the PTO switch
off and back on to turn on the PTO.
The PTO can be turned off by the toggle switch or
pressing the E-STOP button on the transmitter.
The PTO will automatically turn off when enable
mode is deactivated (i.e., after 10 seconds of no
joystick input).
When the E-STOP is pressed down on the
transmitter: both red and green lights will alternate
flashing for a few seconds and then go off once the
shut-down sequence is complete.
The red MACHINE WARNING indicator (left side near
HORN) provides operating error codes by blinking a
number of times followed by a brief pause.
Transmitter Error Codes
Number of Blinks
Machine Warning
Light
Type of Error
1 The parking brake is on.
2 Low oil pressure detected for 20 sec.
3 Machine battery voltage low (<10.4VDC)
4 Machine at same angle too long
5 Machine exceeding maximum
operation angle of 53 degrees
6 Rollover detected (machine over
70 degrees)
Continuous Low oil pressure for more than 40 sec.
Battery
When the battery is new, the run time of the
transmitter will be shorter until it has gone through
several discharge/charge cycles. After the initial few
cycles, the unit typically provides 20 or more hours of
run time before a recharge is needed.
The temperature that the battery is exposed to
affects performance and useful life. To maximize
battery life, keep the battery within the following
limits:
• Charging: –4 to +86 °F
• Operating: –20 to +122 °F
• Storing: –4 to +86 °F (lower is better)
The transmitter will go to sleep irrespective of
receiver status after 20 minutes (by default) if none of
the switches or buttons are pressed.
Battery Charging
The transmitter is designed with a smart battery
charger. The battery can be charged by plugging the
DC cigarette charger or optional AC wall charger
(minimum 2A at 12.6VDC) into the charging port. Red

15
and green lights near the charging port of the
transmitter indicate the status of the charger:
• Red light indicates battery is charging
• Green light indicates battery is fully charged.
Low Oil Pressure
The machine is capable of detecting a low oil
pressure condition. This feature only activates after
the start button is pressed. If the start button is
pressed and the engine does not start, the RC system
may be detecting a low oil condition and begin the
warning sequence outlined below.
Low oil pressure detected:
• After 20 seconds: the machine warning light
blinks two times, the horn will sound for
1 second every 4 seconds.
• After 40 seconds: the machine warning light
stays on continuously, the horn will sound for
5 seconds continuously and the machine will
shut down.
INCLINOMETER (MACHINE ANGLE)
The machine has a built-in inclinometer which
constantly measures the machine tilt angle in all
directions. This safety device provides operator
feedback, machine protection, and automatic
shutdown when certain hazardous conditions are
detected.
If the machine inclinometer measures an angle
of 30 degrees in one direction for more than
10 minutes, the machine warning light blinks
4 times. After 13 minutes it will turn on the horn for
2 seconds every 30 seconds. After 20 minutes it
will go to E-stop mode. If the angle goes under
30 degrees or switches direction for at least
5 seconds, the system returns to normal. This
function is to protect the engine from excessive run
time in a single orientation.
If the machine inclinometer measures an angle of
53 degrees or more, the machine warning light blinks
5 times, the horn will sound for 3 seconds every 10
seconds, and the PTO will automatically turn off.
Once the angle goes under 53 degrees for
more than 5 seconds, the system returns to normal.
This function is intended to warn and inhibit the
operator when attempting to climb beyond the ability
of the machine.
If the machine inclinometer measures an angle of
70 degrees or more (i.e., a rollover accident), the PTO
and engine will automatically turn off. The machine
warning light blinks 6 times and the horn will sound
continuously for 30 seconds. Pushing the
E-STOP down on the transmitter will stop the horn.
This function is intended to shut down the machine
and warn the operator and any bystanders of
imminent danger should a rollover incident occur.
RADIO RECEIVER
The system’s radio receiver (see Figure 11)
communicates with the transmitter and directly
controls the functions on the mower unit. It includes
a port for RS-232 communication for system
diagnostics.
Figure 11
Each of the outputs from the receiver module is
designed with built-in short circuit and overload
protection. The outputs can also detect a no-load or
broken wire condition.
When activated (or turned on), the ON/OFF outputs
will indicate an error if a short is detected. When NOT
activated, the ON/OFF outputs will indicate an error if
the item is disconnected or has a broken wire. The
actuator outputs will detect either a no-load or short
condition when activated by the joystick.
These error conditions are indicated by the red LED
light.
