Please Read This First!
Thank you for purchasing a Mighty Mule Gate
Operator—GTO's "do-it-yourself" automatic gate
operator! When correctly installed and properly used,
your Mighty Mule Gate Operator 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 DVD will
enable you to properly install your Mighty Mule Gate
Operator.
The Mighty Mule Gate Operator is designed for
installation on a pull-to-open single leaf gate (gates
that open into the property). By purchasing an
accessory bracket, the Mighty Mule Gate Operator can
accommodate a push-to-open single leaf gate (gates
that open out from the property). The gate must not
exceed 18 feet in length and weigh more than 350
pounds or exceed 8 feet in length and weigh more
than 850 pounds (please see Technical Specifications
on page 9). The Mighty Mule Gate Operator can be
used on vinyl, aluminum, chain link, farm tube, and
wrought iron gates. 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 operator will obstruct and stop.
The Mighty Mule Gate Operator 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 Mighty Mule Sales
Department (800-543-GATE).
The Mighty Mule Gate Operator features Dual Sense
Technology™. This feature makes the gate stop and
reverse direction when it comes in contact with an
obstruction. This is factory set to the most sensitive
setting and must to be adjusted during installation.
The Mighty Mule Gate Operator 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.
NOTE—If your application requires any of the
following:
• Swing gates longer than 18 feet or weighing
more than 850 pounds
• Slide gates
• Heavy duty or commercial uses
• Professional installation
Go to www.gtoaccess.com for a dealer or retailer near
you or call (800) 543-4283 for information about our
Linear PRO Access professional line of gate operators
and accessories. Our Sales Department will be glad to
give you the name and phone number of a Linear PRO
Access dealer near you.
BEFORE YOU BEGIN TO INSTALL YOUR AUTOMATIC GATE OPERATOR:
watch the enclosed video and read these instructions carefully and completely
to become familiar with all parts and installation steps. The video is only designed as an
overview of the installation procedure. You must read the installation manual for detailed
instructions on gate operator safety and proper use of the gate operator.
ii Mighty Mule FM462 Installation Instructions
Important Safety Information
Because automatic gate operators produce high levels
of force, consumers need to know the potential hazards
associated with improperly designed, installed, and
maintained automated gate operator systems. Keep in
mind that the gate operator is just one component
of the total gate operating system. Each component
must work in unison to provide the end user with
convenience, security, and safety.
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.
This manual contains various safety precautions and
warnings for the installer end user. Because there
are many possible applications of the gate operator,
the safety precautions and warnings contained in
Warnings in this manual are identified with
this warning symbol. The symbol identifies
conditions that can result in damage to the operator or
its components, serious injury, or death.
Because Mighty Mule automatic gate operators are only part of the total gate operating system, it is the
responsibility of the installer or end user to ensure that the total system is safe for its intended use.
Manually Opening and Closing Gate

far enough from the road to prevent traffic congestion.
I. Before Installation
4. This gate operator is intended for vehicular gates
ONLY. A separate entrance or gate must be
installed for pedestrian use (see page 7).
1. Verify this operator is proper for the type and size of
gate, its frequency of use and class of the gate system.
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 operator and safety
devices used with the system (see page 10).
3. Review the operation of the system to become familiar
with its safety features. Understand how to disconnect
the operator for manual gate
operations (see page 2).
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 potential entrapment zones at all times.
7. Identify all of the entrapment zones for the type of
installation. An entrapment zone is an area around the
automatic gate system where a person or object could
be caught that increases the risk of injury. Entrapment
zones must be eliminated or protected with entrapment
protection devices such as photo beams or sensing edges
that connect to the gate operator.

Entrapment Zones are shown in the diagrams on page 3:
Zone 1 – leading edge of the gate and the fence post.
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 operator and gate.
II. During Installation
1. Install the gate operator on the inside of the property and fence line. DO NOT install an operator
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 (sensing
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, 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 operator.
5. Do not activate your gate operator 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 operator
controls in order to prohibit unauthorized use of
the gate.

Important Safety Information
For the Installer and End User
III. After Installation
1. Attach the warning signs (included) to each side
of the gate to alert the public of automatic gate
operation. It is your responsibility to post warning
signs on both sides of your gate. If any of these
signs or warning decals becomes damaged,
illegible, or missing, replace them immediately.
Contact GTO for free replacements.
2. The gate is automatic and could move at any
time, posing serious risk of entrapment. No one
should be in contact with the 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 control away from
children and unauthorized users; store controls
where children and unauthorized users do not
have access to them.
6. KEEP GATES PROPERLY MAINTAINED.
Always turn power to operator OFF before
performing any maintenance. Clean the
push-pull tube with a soft, dry cloth and apply
silicone spray to it at least once per month.
7. Service the gate and gate operator regularly.
Lubricate hinges, spray push pull tube with high
quality silicone spray monthly and replace the
battery every 2-3 years.
vi Mighty Mule FM462 Installation Instructions
8. To operate this equipment safely, YOU must
know how to disconnect the operator for manual

can be obtained by downloading one from the
Mighty Mule® web site (www.mightymule.
com), by contacting GTO, at 3121 Hartsfield
Road, Tallahassee, Florida 32303 or by calling 1-800-543-4283 and requesting a duplicate
copy. One will be provided to you for a nominal fee.
Important Safety Information
For the Installer and End User
Mighty Mule gate operators utilize Dual Sense Technology™ entrapment protection. Dual Sense Technology™ is build into every Mighty Mule and provides
redundant methods of entrapment protection for open
and close gate directions.
In addition to Dual Sense Technology, every Mighty
Mule gate controller has provisions for the connection
of additional obstruction detection devices such as
sensing edges and photo beams.
These devices may be located where there is an
increased risk of obstruction. Refer to the diagram
below.
One or more edge sensors may be located at the leading edge, bottom edge, and post edge, both inside and
outside of a vehicular swing gate system.
Wiring to sensors must be located and arranged so the
wiring between the sensor and the gate operator is not
subjected to mechanical damage.
A wireless sensor such as one that
transmits radio frequency (RF) signals to the gate
operator for obstruction protection functions shall be
located where the transmission of the signals is not
obstructed or impeded by building
structures, natural landscaping or similar
obstruction.

Entrapment Protection
Mighty Mules’s build in Dual Sense Technology™ entrapment protection, even when properly adjusted, may not be sensitive enough to prevent bodily injury in some circumstances. For this reason, devices such as sensing edges (or photoelectric sensors), which stop and reverse gate direction upon sensing an obstruction, are required for enhanced protection
against entrapment.
Entrapment Alarm
The Mighty Mule 562 Automatic Gate Operator is designed to stop and reverse the gate when the gate comes in contact
with an obstruction. Additionally, these operators 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 operator 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.

Important Safety Information
Installing Warning SIgns and Pedestrian Gates
Warning signs alert people of automatic gate operation and are required when installing Mighty Mule Automatic
Gate Operators. A minimum of two WARNING SIGNS must be installed in the area of the gate. Each sign is to be
visible by persons located on the side of the gate on which the placard is installed.
The operator is intended for installation only on gates used for vehicles. Pedestrians must be supplied with a separate access opening. The pedestrian access opening shall be designed to promote pedestrian usage. Locate the gate
such that persons will not come in contact with the vehicular gate during the entire path of travel of the vehicular
gate.
We recommend using the GTO Bulldog Pedestrian Gate Lock (Call the GTO Sales Department at 800-543-4283)
for controlled access.

Before You Begin
1. Determine Charging Options for Battery: Transformer OR Solar
NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT THE SAME TIME!
It will damage the control board!
IMPORTANT
• The battery charge is maintained by the 14 Volt transformer included OR optional solar panel(s). The transformer
OR solar panel is connected to the control board using low voltage, 16 gauge, dual conductor, stranded, direct
burial wire [RB509] (page 26).
• All low voltage wire used with the Mighty Mule Gate Opener must be 16 gauge dual conductor, stranded, direct
burial wire.
• The transformer is intended for indoor use. If the transformer can only be plugged into an outside electrical
outlet, a weatherproof cover or housing must be used.
• If your gate is more than 1000' from an AC power source, you will need to use a solar panel charging kit
(minimum 10 watts). Refer to the Solar Panels and Gate Activity Chart below.

3. Prepare the Gates
• Gates must be plumb, level, and swing freely on their hinges.
• Wheels must NOT be attached to the gates.
• The gates must move throughout their arcs without binding or dragging on the ground.
• Note that gates over 250 lb. should have ball bearing hinges with grease fittings.
• The gate post should be be secured in the ground with concrete so it will minimize twist or flex when the opener
is activated.
• 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.
• Trench the driveway in order to lay PVC conduit for the second opener power cable (see illustration on page 6).

• Low voltage wire [RB509] will be needed to run from the transformer to the opener control board; length
depends upon the distance between the transformer power supply and the control box. (Page 14 & 26)
• If your gate is more than 1000' away from an AC power source you will need to use at least one 10 Watt solar
panel [FM123] or two 5 Watt panels (FM121) to charge the 12 Volt battery. (Page 2 & 26)
• PVC conduit for protecting wiring. (Page 6)
• Push-To-Open Brackets [FM148] are required if gates open out from property. (Page 3 & 26)

IMPORTANT: To achieve the most efficient
leverage for the gate opener and ensure long
trouble free service, the gate opener needs to
be installed within the following parameters.
The diagram at left shows the optimum
position for gate opener arm in relation to
the gate in the open and closed positions.
Be sure the position of the gate opener and
brackets allows for 1" 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" from the end of the
retracted opener arm to the gate bracket with
the gate in the closed position.

Installation of the FIRST Gate Opener
IMPORTANT: Determine which side of the driveway you will mount the control box. From this point on, the gate and
gate opener on the same side as the control box will be referred to as the FIRST gate and gate opener. The gate and
gate opener on the opposite side of the driveway from the control box will be referred to as the SECOND gate and gate
opener.
We recommend you position the opener near the centerline of the gate to keep the gate from twisting and flexing
and to avoid backsplash from rain water.
The Post Bracket Assembly
Wooden Post Metal Plate
The position of the post bracket assembly
determines the leverage and efficiency of the
opener. The post bracket assembly position
also sets the clearance between the opener
and the gate in the open and closed positions.
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 must
completely penetrate the post.

The post pivot bracket may not be necessary on posts larger than 6" in diameter (see page 6). Fence posts smaller
than 6" in diameter or 6" square should be made of metal instead of wood to remain stable while the opener is moving
the gate.
Reinforcing Gates for the Gate Brackets
We recommend using a muffler clamp, wood, or metal, 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. Additional hardware may be
needed depending on the installation.

Be sure the position of the gate opener and
brackets allows for 1" of clearance between
the gate and the opener in both the open
and closed position, while at the same time
maintaining a maximum distance of 13"
from the end of the retracted opener arm to
the gate bracket with the gate in the closed

opener the most efficient leverage point for
operation and provides the least possible
pinch area
Step 6
After verifying that you have the best position
for the post pivot bracket in the open position,
insert the 5/16" x 11/2" 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. Again,
check the clearance and be sure that the gate
opener is not binding at the post pivot bracket.

Install the SECOND gate opener and hardware on the second gate following the same procedures as the FIRST gate
opener and hardware ("Installing Post Bracket Assembly and Gate Bracket" Steps 1–10).
NOTE: The power cable for the Second Opener should be run in PVC conduit under the driveway to protect it from
damage due to lawnmowers, heavy equipment, etc. (See illustration on page 6.) NEVER SPLICE opener arm power
cables. This will cause performance problems and may damage the opener.

Install the Closed Position Stop Plates
The closed position stop plate is attached to the FIRST gate to help stabilize the gate leaf in the closed position. An
optional low profile ground stop, when used with the closed position stop plate, provides a secure point for the SECOND
gate to close against.
To further enhance the stability and security of your gate, install a Mighty Mule Automatic Gate Lock [FM143] page 26).If
you will be using the Mighty Mule Gate Lock with your gate opener system, the closed position ground stop is required.
For Pull-to-Open systems, install the closed position stop plates on the inside of the gates.

NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT THE SAME TIME!
IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE:
• The only wire acceptable for use with GTO products is 16 gauge stranded, low voltage, direct burial wire. This
particular gauge enables the transformer to provide an adequate charge through the control board to the battery
at distances up to 1000'.
• DO NOT use telephone wire or solid core wire. Unlike 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.
Step 1
Make sure the power switch is OFF.
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 (up to 1000').

Adjust the Stall Force Setting
The Stall Force potentiometer controls the the amount of force the
opener will apply against an obstruction before it stops and reverses
direction within two seconds.
IMPORTANT: The Stall Force setting will need to be adjusted to
compensate for the weight and size of your gates. For safety reasons,
use the lowest possible setting to operate the gate.
The Stall Force potentiometer on the control board operates like a
volume control on a radio. Use a small flat blade screwdriver to turn the
arrow in the center of the potentiometer. Adjust the sensitivity from the
MINIMUM position just to the point where the gates operate smoothly
without obstructing from their own weight or wind conditions.

Push-To-Open Installation Instructions
PUSH-TO-OPEN gates open out from the property (opener arms extend to open). Push-To-Open Brackets are required
for this type of installation, one for each gate [FM148] page 26. In a Push-To-Open installation, the opener is installed
while the gate is in the closed position and the opener fully retracted.
Swinging gates MUST NEVER open into public access areas!
Step 1: Read "Installation of the Gate Opener" on page 7.
Step 2: Determining The Mounting Position of The Post Bracket Assembly
A. Insert the 3/8" x 11/2" bolt through the center hole of the post
brackets and post pivot bracket. Secure with a 3/8" washer
and 3/8" lock nut. DO NOT overtighten the lock nut (the post
pivot bracket will have to be adjusted later). 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.
B. With the gate in the closed position (up to 110º from its open
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.
IMPORTANT: Be sure the position of the gate opener and
brackets allows for 1" of clearance between the gate and the
opener in both the open and closed position, while at the same
time maintaining a maximum distance of 13" from the end of
the opener arm to the gate bracket with the gate in the open
position. This mounting position will give the opener the most
efficient leverage point for operation and provides the least
possible pinch area.
C. After verifying that you have the best position for the post
pivot bracket in the closed position, insert the 5/16" x 11/2" 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 open position. Again, check the
clearance and be sure that the gate opener is not binding at
the post pivot bracket.
IMPORTANT: If you don't have the required clearance, or if
the gate opener is binding, remove the 5/16" x 11/2" bolt and
readjust the post pivot bracket. TIP: Turn the post pivot bracket
over for more hole alignment options.

D. When the post pivot bracket assembly is in the optimum
position, reattach the opener to the gate bracket (gate in the
closed position); recheck the gate opener level; make sure the brackets are clamped securely. Mark reference
points for bolt holes on the post through middle of post bracket slots. Mark reference points for bolt holes on the
gate cross member through middle of gate bracket slots. After marking your reference points, remove the opener
and brackets from the post and gate.
E.Drill 3/8" holes through post as marked. Fasten post bracket assembly to the post using two 3/8" x 8" bolts,
washers and lock nuts. You must use bolts that completely penetrate the post. Drill 3/8" holes through the
gate cross member as marked. Mount gate bracket using two 3/8" x 2 3/4" bolts, washers, and lock nuts.

Step 9: Set the Open Position Limit (Push-to-Open)
Push-To-Open Jumper
The CLOSED limit is when the opener is fully retracted and the gate is
in the closed position. The closed limit setting can only be adjusted by moving the gate bracket. To acheive the optimum
open position, you must adjust the OPEN Limit setting:
A. If not already ON slide the ON/OFF switch on the Control Box to the ON position and make sure the arms are in
the CLOSED POSITION (fully retracted).
B. Press and HOLD the FIRST Opener OPEN button on the control board and be prepared to RELEASE the button
when the gates reached the desired open position/limit. Use the JOG OPEN and CLOSE buttons to "fine tune"
the gate position if neccessary.
C. Press and HOLD the SECOND Opener

Solar Panel Instructions
NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT THE SAME TIME!
It will damage the control board!
IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE:
• The only wire acceptable for use with GTO products is 16 gauge stranded, low voltage, PVC sheathed wire. This
particular gauge enables the solar panel to provide an adequate charge through the control board to the battery
at distances up to 250'.
• DO NOT use telephone wire or solid core wire. Unlike stranded wire, these types of wire are inadequate for use
with your gate opener system.
