Thank you for purchasing a Mighty Mule® 200 E-Z Gate Opener—GTO's "do-it-yourself" automatic gate
opener! When correctly installed and properly used, your Mighty Mule® E-Z Gate Opener will give you
many years of reliable service. Please read the following information and watch the enclosed video to
ensure you have the correct system for your particular needs. Furthermore, this manual and the video will
enable you to properly install your Mighty Mule® E-Z Gate Opener.
The Mighty Mule® 200 E-Z Gate Opener is designed for installation on a pull-to-open single leaf gate
(gates that open intothe property). The gate must not exceed 12 feet and 300 pounds (please see Technical Specifications on page 10). The Mighty Mule® E-Z Gate Opener can be used on vinyl, aluminum, chain
link, farm tube, and wrought iron gates. Use on solid gates is not recommended. Solid surface gates have
a high resistance to the wind.
Use on solid (surface) gates is not recommended. Solid surface gates have a high
resistance to the wind. If the wind is strong enough, the opener will obstruct and
stop, blow fuses, or may damage the equipment.
The Mighty Mule® E-Z Gate Opener accommodates extra transmitters, digital keypads, solar panels,
push buttons, automatic gate locks, and other access control products. These optional accessories (see the enclosed Mighty Mule® Accessory Catalog) are available at most stores. Your store should be able to
special order any accessory not in stock. If your store cannot special order accessories, please call the
GTO Sales Department (800-543-GATE).
The Mighty Mule® E-Z Gate Opener features adjustable obstruction sensing. This safety feature
makes the gate stop and reverse direction within 2 seconds when it comes in contact with an obstruction.
MIN is the factory setting; meaning the gate will exert the minimum force on an obstruction before it stops
and reverses direction.
The Mighty Mule® E-Z Gate Opener also has an adjustable auto-close feature. After the gate reaches
the fully open position, it can be set to remain open up to 120 seconds before automatically closing.
Pressing the transmitter button at any time after the gate opens fully will cause it to close immediately.
OFF is the factory setting; meaning the gate will stay open until you press the transmitter (or keypad, etc.)
again.

Hairpin Clip
Gate Bracket
Front Mount
Bushing
Because automatic gate openers produce high levels of force, consumers need to know the potential
hazards associated with improperly designed, installed, and maintained automated gate opener systems.
Keep in mind that the gate opener is just one component of the total gate operating system. Each
component must work in unison to provide the consumer with convenience, security, and safety.
This manual contains various safety precautions and warnings for the consumer. Because there are many
possible applications of the gate opener, the safety precautions and warnings contained in this manual
cannot be completely exhaustive in nature. They do, however, provide an overview of the safe design,
installation, and use of this product. CAREFULLY READ AND FOLLOW ALL SAFETY PRECAUTIONS,
WARNINGS, AND INSTALLATION INSTRUCTIONS TO ENSURE THE SAFE SYSTEM DESIGN,
INSTALLATION, AND USE OF THIS PRODUCT.
Precautions and warnings in this manual are identified with this warning symbol. The symbol
identifies conditions that can result in damage to the opener or its components, serious injury, or death.
Because GTO automatic gate openers are only part of the total gate operating system, it is the
responsibility of the consumer to ensure that the total system is safe for its intended use.
To Manually Open and Close the
Gate, Follow the Procedure Below:
CAUTION: The gate will move freely and uncontrolled when the gate opener
is removed from the gate. ONLY disconnect the opener when the opener power
switch is OFF and the gate is NOT moving.
Disconnecting the Opener
1. Turn opener power switch OFF.
2. Remove hairpin clip, clevis pin, and
bushing from the front mounting point.
3. Remove the opener from the mount.
The gate can be opened and closed
manually when the opener is disconnected.
IMPORTANT: NEVER allow opener arm to hang
by the front mount - it will break from the arm weight.
CAUTION: Because the Mighty Mule gate opener
is battery powered, disconnect the opener ONLY when the
power switch on the opener is turned OFF. Unplugging the
transformer does not turn power to the opener OFF.
NOTE: Substitute a Pin Lock (FM133) for the clevis pin on
the front mount only of the gate opener to prevent unauthorized
removal of the opener from the gate
(see Accessory Catalog).

For The Consumer
WARNING: To reduce the risk of injury or death:
1. READ AND FOLLOW ALL INSTRUCTIONS. Failure to meet the requirements set forth in the instruction
manual could cause severe injury and/or death, for which the manufacturer cannot be held responsible.
2. When designing a system that will be entered from a highway or main thoroughfare, make sure the
system is placed far enough from the road to prevent traffic congestion.
3. The gate must be installed in a location that provides adequate clearance between it and adjacent
structures when opening and closing to reduce the risk of entrapment. Swinging gates must not open
into public access areas.
4. The gate and gate opener installation must comply with any applicable local codes.
I. Before Installation
1. Verify this opener is proper for the type and size of gate, its frequency of use and the proper class rating.
2. Make sure the gate has been properly installed and swings freely in both directions. Repair or replace
all worn or damaged gate hardware prior to installation. A freely moving gate will require less force to
operate and will enhance the performance of the opener and safety devices used with the system.
3. Review the operation of the system to become familiar with its safety features. Understand how to
disconnect the opener for manual gate operation (see page 1).
4. This gate opener is intended for vehicular gates ONLY. A separate entrance or gate must be installed
for pedestrian use (see page 6).
5. Always keep people and objects away from the gate and its area of travel. NO ONE SHOULD CROSS
THE PATH OF A MOVING GATE.
6. Pay close attention to the diagram below and be aware of these areas at all times.

Zone 2 – between the gate and the gate post.
Zone 3 – the path of the gate.
Zone 4 – the space between the gate in the open position and any object such as a wall, fence, tree, etc.
Zone 5 – pinch points between the opener and gate.
II. During Installation
1. Install the gate opener on the inside of the property and fence line. DO NOT install an opener on the
outside of the gate where the public has access to it.
2. Be careful with moving parts and avoid close proximity to areas where fingers or hands could be pinched.
3. Devices such as contact sensors (safety edges) and non contact sensors (photo beams) provide
additional protection against entrapment.
4. If push buttons or key switches are installed, they should be within sight of the gate, yet located at least
10 feet from any moving part of the gate (see diagram below). Never install any control device where a
user will be tempted to reach through the gate to activate the gate opener.
5. Do not activate your gate opener unless you can see it and can determine that its area of travel is clear of
people, pets, or other obstructions. Watch the gate through its entire movement.
6. Secure outdoor or easily accessed gate opener controls in order to prohibit unauthorized use of the gate.

IMPORTANT SAFETY INSTRUCTIONS
III. After Installation
1. Attach the warning signs (included) to each side of the gate to alert the public of auto matic gate
operation. It is your responsibility to post warning signs on both sides of your gate. If any of these signs
or warning decals become damaged, illegible or missing, replace them immediately. Contact GTO for
free replacements.
2. The gate is automatic and could move at any time, posing a serious risk of entrapment. No one should
be in contact with an activated gate when it is moving or stationary.
3. Do not attempt to drive into the gate area while the gate is moving; wait until the gate comes to a
complete stop.
4. Do not attempt to "beat the gate" while the gate is closing. This is extremely dangerous.
5. Do not allow children or pets near your gate. Never let children operate or play with gate controls.
Keep the remote controls away from children and unauthorized users; store controls where children and
unauthorized users do not have access to them.
6. KEEP GATE AND GATE OPENER PROPERLY MAINTAINED. Always turn power to opener OFF before
performing any maintenance. Regularly grease the gate hinges. Clean the push-pull tube with a soft, dry
cloth and apply silicone spray to it at least once per month.
7. To operate this equipment safely, YOU must know how to disconnect the opener for manual gate
operation (see page 1). If you have read the instructions and still do not understand how to disconnect
the opener, contact the GTO Service Department.
8. Disconnect the opener ONLY when the power is TURNED OFF and the gate is NOT moving.
9. Make arrangements with local fire and law enforcement for emergency access.
10. Distribute and discuss copies of the IMPORTANT SAFETY INSTRUCTIONS section of this manual with
all persons authorized to use your gate.
11. IMPORTANT: Save these safety instructions. Make sure everyone who
is using or will be around the gate and gate opener are aware of the
dangers associated with automated gates. In the event you sell the
property with the gate opener or sell the gate opener, provide a copy
of these safety instructions to the new owner.

Secondary Means of Protection Against
Entrapment
As specified by Gate Opener Safety Standard, UL 325 (30A.1.1), automatic gate openers shall have
an inherent entrapment sensing system, and shall have provisions for, or be supplied with, at least one
independent secondary means to protect against entrapment. The Mighty Mule® utilizes Type A, an
inherent (i.e., built-in) entrapment sensing system as the primary type of entrapment protection. Also, the
Mighty Mule® has provisions for the connection of Type B2 protection to be used as the secondary type
of entrapment protection, if desired.
1. For gate openers utilizing a contact sensor (e.g., safety edge sensor– Type B2) in accordance with UL
325 (51.8.4 [i]):
A. One or more contact sensors shall be located at the leading edge, bottom edge, and post edge,
both inside and outside of a vehicular swing gate system.
B. A hard wired contact sensor shall be located and its wiring arranged so that the communication
between the sensor and the gate opener is not subjected to mechanical damage.
C. A wireless contact sensor such as one that transmits radio frequency (RF) signals to the gate
opener for entrapment protection functions shall be located where the transmission of the signals are
not obstructed or impeded by building structures, natural landscaping or similar obstruction. A wireless
contact sensor shall function under the intended end-use conditions.
ENTRAPMENT ALARM (UL 325; 30A.1.1A)
The Mighty Mule® E-Z Gate Opener is designed to stop and reverse within 2 seconds when the
gate comes in contact with an obstruction. Additionally, these openers are equipped with an audio entrapment alarm which will activate if the unit obstructs twice while opening or closing. This alarm
will sound for a period of 5 minutes, or until the opener receives an intended signal from a hard wired
entry/exit source (e.g. push button control or keypad) and the gate returns to a fully open or fully closed
position. Turning the power switch on the control box OFF and back ON will also deactivate the alarm.
Wireless controls such as transmitters and wireless keypads will not deactivate the alarm.

Required Safety Precautions for Gates
Install Warning Signs
Warning signs alert people of automatic gate operation and are required when installing the Mighty Mule®
E-Z Gate Opener. Furthermore, a walk-through gate must be installed if pedestrian traffic is expected near
the vehicular gate. We recommend using the GTO Bulldog Pedestrian Gate Lock (Call the GTO Sales Department) for controlled access.
Entrapment Protection
GTO’s inherent obstruction settings, even when properly adjusted, may not be sensitive enough to
prevent bodily injury in some circumstances. For this reason, safety devices such as safety edge
sensors (or photoelectric sensors), which stop and reverse gate direction upon sensing an obstruction,
are suggested for enhanced protection against entrapment.
Warning Signs
The warning signs (at right) must
be installed on both sides of the
gate (see page 7 for details).

The gate must be plumb, level, and swing freely
on its hinges. Wheels must not be attached to
the gate. The gate must move throughout its arc
without binding or dragging on the ground.
Note that gates over 250 lb.. should have ball
bearing hinges with grease fittings.
The fence post should be no larger than 6" in
diameter and must be secured in the ground
with concrete so it will minimize twist or ex
when the opener is activated. We recommend
you position the opener near the centerline
of the gate to keep the gate from twisting and
exing and to avoid backsplash from rain water.
The addition of a horizontal or vertical cross
member (if one is not already in place) to provide
a stable area for mounting the gate bracket is
also important.

IMPORTANT: To achieve optimum leverage for the gate opener and ensure long trouble free service, the
gate opener needs to be installed within the following perameters.
The diagram below shows the optium position for gate opener arm in relation to the gate in the open and
close positions.
Be sure the position of the gate opener and brackets allows for 1 inch of
clearance between the gate and the opener in both the open and closed
position, at the same time maintaining a maximum distance of 13 inches
from the end of the opener arm to the gate bracket with the gate in the
closed position.
If the gate post is larger
than 6 inches the Post Pivot
Bracket can be removed and
the center hole of the Post
Bracket can be the mounting
point for the gate opener.

The position of the post bracket determines the leverage and efficiency of the opener. The post bracket
position also sets the clearance between the opener and gate in the open and closed positions.
The curved design of the post bracket
works well for installations on round and
square fence posts. Because the post
bracket carries the entire thrust of the
active opener, bolts that completely
penetrate the fence post must be used.
On wooden posts, place a metal plate or
washer (not supplied) between the nuts
and the fence post to prevent the thrust
of the opener from pulling the bolts and
washers out of the wood.
NOTE: A fence post smaller than 6" in
diameter or 6" square should be made
of metal instead of wood so that it will
remain stable while the opener is moving the gate.
NOTE: The post pivot bracket may not need to be used on post larger than 6" in diameter.
IMPORTANT:
We recommend using a mufer clamp, wood, or metal (not included) to reinforce thin walled tube gates or
wood to reinforce panel gates as shown. These reinforcement methods will prevent damage to the opener
and gate when the opener is installed. Additional hardware may be needed depending on the installation.

Insert the 3/8" x 11/2"
bolt through the center
hole of the post brackets
and post pivot bracket
as shown. Fasten a 3/8"
washer and 3/8" lock nut
on the end of the bolt.
DO NOT overtighten the
lock nut because the
post pivot bracket will
have to be adjusted later.
REMINDER:
The following steps are
intended for pull-to-open
gate installations only.
Step 2
Attach post bracket assembly to the rear mount of the opener with a clevis pin and a 3/8" washer. Secure
the clevis pin with a hairpin clip. Attach gate bracket to the front mount of the opener with a clevis pin and a
3/8" bushing. Secure the clevis pin with a hairpin clip
Step 3
With the gate in the open position (up to 110º from its closed position), and the opener fully retracted,
adjust the post bracket assembly and gate bracket until the opener is level. While holding the opener level,
use C-clamps to temporarily keep the post bracket assembly and gate bracket in their respective positions
on the fence post and gate.

position allows for minimum 1 inch of clearance between the gate and the opener in both the open and
closed positions, as well as maintaining the maximum 13" distance explained in the gate installation overview
earlier. This position will give the opener the most efficient leverage point for opening and closing the gate
and more importantly provides the least possible pinch area.
Step 4
After verifying that you have the best position for the post pivot bracket in the open position, insert the
5/16" x 1-1/2" bolt through the aligned holes of the post bracket and post pivot bracket to hold it in place.
Remove the clevis pin from the front mount and while supporting the gate opener, swing the gate and gate
opener to the closed position. With the gate and gate opener in the closed position check the clearance
and be sure that the gate opener is not binding at the post pivot bracket.
If you don't have 1 inch of clearance, the gate opener is binding on the post pivot bracket, or you don't
have 13' or less from the front mount to the gate bracket in the closed position, remove the 5/16" x 1-1/2"
bolt and readjust the pivot bracket until you can achieve these important clearances and distance.
With the post pivot bracket in the optimum position for clearance and freedom of movement, reattach
the opener to the gate bracket in the open position and recheck the gate opener level and make sure the
brackets are clamped securely.
TIP: Turning the pivot bracket over gives
more hole alignment options for the post
pivot bracket assembly. You can also move
the entire post pivot bracket assembly to
different positions on the gate post to help
achieve the proper clearances.

and adjust the post bracket assembly if necessary.
Installation of the Closed Position Stop
The Mighty Mule® Gate Opener firmly holds the gate in the closed position using the
positive stop plate. The positive stop helps stabilize the gate leaf in the closed position.
To further enhance the stability and security of your gate, install the optional
Mighty Mule® Automatic Gate Lock (seeAccessory Catalog).
Step 10
Remove hairpin, clevis pin, and bushing from
front mount and close the gate (remember to
support opener). Fasten the closed position stop
plate to the end of the gate frame on the gate
centerline, but do not tighten it completely. Slide
the stop plate toward the fence post until they
touch (see illustration). Once you have moved
the stop plate to the correct position, tighten its
hardware completely.
Use the appropriate hardware for your type of
gate (use U-bolts or a mufer clamp if you have
a tube or chain link gate). This hardware is NOT
provided.

mounting the control box check
the checklist below to be sure
that you have completed the
important installation steps.
CHECK LIST
• The gate is plumb, level, and swings smoothly on its hinges.
• A plate or support was added for the gate bracket (if necessary).
• The opener is level and mounted on the centerline of the gate.
• The closed position stop plate is installed in place.
Mounting the Control Box
• Unravel the coiled up power cable attached to the control box and opener.
• Mount control box at a location that achieves optimal receiver/transmitter range.
• The top of the fence is an acceptable location for mounting the control box.
• If necessary, attach a backing piece of wood when mounting the control box to a metal fence.
• Leave enough slack in the cable for gate operator movement.

Powering Options: Transformer or Solar
IMPORTANT
• The Mighty Mule 200 is designed and intended for use with a 12 Volt automotive or marine type
battery. The battery must be placed inside a weatherproof case and located within 6 feet of the
opener arm. The 8 foot harness supplied connects the battery to the opener arm.
• The battery charge is maintained by the 18 Volt transformer included or by using optional solar
panel(s). The transformer orsolar panel is connected to the opener arm control board using
low voltage, 16 gauge, dual conductor, multi-stranded, direct burial wire (RB509) (see the
Accessory Catalog).
• All low voltage wire used with the Mighty Mule® Gate Opener must be 16 gauge dual
conductor, multi-stranded, direct burial wire (see page 22 and the Accessory Catalog). Do not
run more than 1000 feet of wire.
• The transformer is designed and intended for indoor use. If the transformer can be plugged
only into an outside electrical outlet, a weatherproof cover or housing (available at local
electrical supply stores) must be used.
• If your gate is more than 1000 ft. from an ac power source, you will need to use at least one 5
watt Solar Panel to charge the battery (see Accessory Catalog). Refer to the Solar Panels and
Gate Activity chart below.
NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT THE SAME TIME
– it will damage the control board –

IMPORTANT: Make sure the power switch on the control box is in the
OFF position.
Step 2
Place the 12 Volt automotive or marine type battery and its
weatherproof case within 6 feet of the fence post where the opener arm
is mounted.
Step 3
Attach the battery wires provided, to the terminals of the battery. Take
care to attach the BLACK wire to the NEGATIVE terminal and the RED
wire to the POSITIVE terminal. Reverse connection will cause damage
to the control board.
Connecting the Transformer
IMPORTANT: Use either transformer
or solar panel. DO NOT connect both
transformer and solar panels to the opener
control board at the same time. It will
damage the control board.
Step 1
Make sure the power switch is OFF before
proceeding to the next step.
Step 2
Select the electrical outlet where you will
plug the transformer. Measure the distance
from this outlet to the control box following
the path where the wire will be laid. After
you have measured how much wire is
needed, cut the wire to the appropriate
length.
Step 3
Lay the measured length of low voltage
wire in a trench following a path from the
selected electrical outlet to the control box.
Wires coming up from the ground should
be run through PVC conduit to protect them
from lawn mower blades, weed eaters, and
grazing animals. Be sure to bury the wire
laid in the trench.

IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE
The only wire acceptable for use with GTO products is 16 gauge multi-stranded, low voltage,
PVC sheathed wire. This particular gauge enables the transformer to provide an adequate
charge through the control board to the battery at distances up to 1000 ft.
DO NOT use telephone wire or solid core wire. Unlike multi-stranded wire, these types of wire
are inadequate for use with your gate opener system.
NEVER splice wires together. Splicing permits corrosion and seriously degrades the wire's
ability to carry an adequate current.

Note: Must have a transmitter that operates the gate. If not see 'Setting Your
Personal Transmitter Code' on page 26.
Your Mighty Mule 200 has two Limit Settings
1.OPEN Limit setting: (Gate in the OPEN POSITION / FACTORY SET &
NOT ADJUSTABLE) The open limit setting is the fully open position.
2.CLOSED Limit setting: The CLOSED Limit setting (gate in the
CLOSED POSITION) To achieve optimum closed position, you are
required to complete the following FIVE STEPS:
Step 1
With the gate in the fully open position (arm fully retracted), slide the ON/OFF switch on the control box
to the OFF position. If gate is not open, use the transmitter to put the gate into the fully open position,
then slide the ON/OFF switch on the control box to the OFF position.
Step 2
Press and hold the hand held transmitter button while sliding the ON/OFF switch to the ON position.
Continue to hold the transmitter’s button until the alarm sounds (3-5 seconds). The unit is now in the
‘LEARN LIMIT’ mode. (In this mode the unit will run only when the transmitter is held down. The
gate will stop when the transmitter’s button is released. The gate will alternate its running direction each
time the button is pressed.)
Step 3
Press and hold the transmitter’s button to close the gate. Prepare to release the transmitter’s button
when the gate reaches the desired closed position. (Note: Use the transmitter to ‘fine-tune’ the closed
position of the gate. Make sure the last running state is in the closing direction). The gate is now at the
desired closed position limit.
Step 4
Press & hold the transmitter to run the gate open
uninterrupted all the way to the full open limit. If the
gate stops prior to reaching the open limit position,
bring the gate back to the desired closed position
and repeat steps 2 and 3. (Note: If the gate stops and
reverses while the transmitter is held down, the ‘STALL
FORCE’ adjustment may be set too low. Turn ‘STALL
FORCE’ pot clockwise and repeat steps 2-3)
Step 5
Once the gate reaches the open position limit you
will hear a single beep from the alarm confirming
that the closed position limit is ‘learned’. The unit will

IMPORTANT: For safety reasons the obstruction setting
or Stall Force on the Mighty Mule® control
board comes from the factory set at MIN
(minimum). In many gate installations this
setting will need to be adjusted to overcome
the weight and size of the gates.
The Stall Force potentiometer on the
control board operates like a volume
control on a radio. It controls the
obstruction sensitivity (or the amount
of force the opener will apply to an
obstruction) before it automatically stops
and reverses direction for approximately
two (2) seconds.
Use a small slotted screwdriver to turn the
arrow in the center of the potentiometer. Adjust
the sensitivity from the MINIMUM position where
the gate operates without obstructing from its own
weight or the wind conditions in your area.
NOTE: You may need to increase the stall force in cold
weather due to increased resistance from gate hinges.
ALWAYS KEEP SAFETY AT THE TOP OF YOUR LIST
WHEN ADJUSTING OR
SERVICING YOUR AUTOMATIC GATE OPENER!
Setting Auto-Close Time
CLOSE TIME (auto close timer): Determines
how long the gate will remain open before it
automatically closes. The limits are OFF and

Setting Your Personal Transmitter Code
All GTO transmitters are set to a standard code at the factory and are
ready to operate your Mighty Mule® Gate Opener
®
. For your safety and
security, however, we strongly recommend that you replace the factory
setting with your own personal code. Follow the directions below:
1. Remove the Transmitter Cover
On the back of the transmitter use a small phillips head screw driver
to remove the two screws on the sides of the visor clip and separate
the front cover from the transmitter. With the front cover removed,
the battery and the DIP switches will be exposed. To set a new code,
use a small screwdriver to move the switches.
2. Set the Transmitter DIP Switches
There are nine (9) transmitter DIP switches; each can be placed in three
different positions (+, 0, –). DO NOT set all the switches in the same
position, such as all +, all 0, or all –. Once the DIP switches have been
set to a personal code, replace and close the access cover.
WARNING: No other adjustments should be made inside the transmitter.
3. “Learn” the New Code to Control Board Memory
A. Slide the ON/OFF switch to the OFF position.
B. Press and hold the hand held transmitter
button while sliding the ON/OFF switch
to the ON position.
C. Continue to hold the transmitter's button
until the alarm sounds (3-5 seconds).
D. Release the transmitter's button. The new
transmitter code is 'learned'.
E. Verify that the transmitter operates the gate.
NOTE: It is NOT necessary to remove the cover
of the control box to 'learn' the new transmitter
code.

IF THIS OPENER WILL BE USED WITH GATES THAT ARE MOUNTED ON
MASONRY, BRICK, OR ROCK (etc.) COLUMNS:
READ THE FOLLOWING CAREFULLY BEFORE PROCEEDING
A. The simplest solution is to install the opener in a push-to-open configuration (requires Push-To-Open
Bracket, see Accessory Catalog). The minimum clearance is easier to achieve and clearance is no
longer a problem, since the opener will be pushing the gate away from the column instead of pulling it
toward the column. It is recommended that you place a steel plate between the opener mounting
brackets and masonry surface for additional strength.
B. If a push-to-open installation is impossible due to traffic hazards, terrain, etc., another option is to re-
hang the gate. You may hang it on a post, either in the center of the column or at the back corner, or
move the gate to the back corner of the columns.
C. The most difficult solution is to cut a notch in the column to accommodate the opener and power cable.
This job is NOT for the inexperienced!
