iv Mighty Mule MM360 Installation Instructions
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 16 feet in length or weigh more
than 550 pounds (please see Technical Specications
on page 8). 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
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 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 16 feet or weighing
more than 550 pounds
• Slide gates
• Heavy duty or commercial uses
• Professional installation
Go to www.gtoaccess.com for a dealer or retailer near
you or call [phone] 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.

Clevis Pin
Hairpin Clip
Gate Bracket
Front Mount
Bushing
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 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
Disconnecting the Operator
1. Turn control box power switch OFF.
2. Remove hairpin clip, clevis pin, and bushing from
either the front or rear mounting point.
3. Remove the operator from the mount.
The gate can be opened and closed manually
when the operator is disconnected.
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.
Warnings in this manual are identied with
this warning symbol. The symbol identies
conditions that can result in damage to the operator or
its components, serious injury, or death.
Manually Opening and Closing Gate
Because Mighty Mule automatic gate operators are only part of the total gate operating system, it is the
responsibility of the installer and end user to ensure that the total system is safe for its intended use.
CAUTION
The gate will move freely and uncontrolled when the gate operator is removed from the gate. ONLY discon-
nect the operator when the control box power switch is OFF and the gate is NOT moving.
NOTE: Substitute a Pin Lock for the clevis pin on the front mount of the
gate operator to prevent unauthorized theft of the operator from the gate
(see accessory pages in back of this book).

Important Safety Information
I. Before Installation
1. Verify this operator is proper for the type and size of gate,
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 dam-
aged gate hardware prior to installation. A freely moving
gate will require less force to operate and will enhance the
performance of the entrapment protection 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 operation (see page 1).
4. The gate and operator installation must comply with any ap-
plicable local codes.
5. This gate operator is intended for vehicular gates only. A
separate entrance or gate must be installed for pedestrian use
(see page 6).
6. Always keep people and objects away from the gate and its
area of travel. No one should cross the path of a moving gate.
7. Identify all of the entrapment zones for the type of installa-
tion. An entrapment zone is an area around the automatic gate
system where a person or object could be caught that increase
the risk of injury. Entrapment zones must be eliminated,
guarded or protected.
8. When designing a system that will be entered from a highway
or main thoroughfare, make sure the gate system is placed far
enough from the road to prevent trafc congestion.
WARNING
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. Never let children operate or play with gate controls. Keep the remote
control away from children.
3. Always keep people and objects away from the gate. NO ONE
SHOULD CROSS THE PATH OF THE MOVING GATE.
4. Test the gate operator monthly. The gate MUST reverse on contact with
a rigid object or stop when an object activates the non-contact sensors.
After adjusting the force or the limit of travel, retest the gate operator.
Failure to adjust and retest the gate operator properly can increase the
risk of injury or death.
5. Use the manual/emergency release only when the gate is not moving.
6. KEEP GATES PROPERLY MAINTAINED. Read the
user’s manual. Have a qualied service person make repairs to
gate hardware.
7. The entrance is for vehicles only. Pedestrians must use sepa-
rate entrance.
8. 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.
9. SAVE THESE INSTRUCTIONS.

erty 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 ngers or hands could
be pinched.
3. Devices such as contact sensors (sensing
edges) and non contact sensors (photo beams)
provide additional protection against vehicular
damage.
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.

Mighty Mule MM360 Installation Instructions 5
Important Safety Information
For the Installer and End User
Mighty Mule gate operators utilize Dual Sense Tech-
nology™ entrapment protection. Dual Sense Technol-
ogy™ is built 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 lead-
ing 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
blocked or impeded by building
structures, natural landscaping or similar
objects.
Entrapment Alarm
The Mighty Mule 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.

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 12 volt automotive/marine battery must be charged by either connecting the
transformer (included) or solar panel kit to the control board.
• The transformer is designed for indoor use. If the transformer can be plugged only into an
outside electrical outlet, a weatherproof cover/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 5
watts solar charging power to charge the battery. Refer to the Solar Panel and Gate Activity
chart below.
• All low voltage wire used with the Mighty Mule Gate Opener must be 16 gauge, dual
conductor, stranded, direct burial wire. Do not run more than 1000 ft. of wire.
Solar Panel and Gate Activity Chart
The table and map illustrate the maximum number of gate cycles to expect per day in a particular area
when using from 5 to 30 watts of solar charging power prior to the battery depleting to a state where the
unit will not function. The figures shown are for winter (minimum sunlight) and do not account for the use
of any accessory items.
Accessories connected to
your system will draw additional power
from the battery and will require additional
solar panels. A deep cycle marine battery is
recommended for solar and/or high traffic
applications.
NOTE: UP to 250 ft. of 16 gauge dual
conductor, stranded, direct burial wire may
be used to allow installation of solar panels in
direct sunlight.

2. Check Direction of Gate Swing
The Mighty Mule Gate Opener is designed for PULL-TO-OPEN installations. PUSH-TO-OPEN installations require a
Push-To-Open bracket [FM148, not included]. Push-to-Open Installation Instructions begin on page 32.
3. Prepare the Gate
• 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 arcs without
binding or dragging on the ground.
• Note that a gate over 250 lbs. should have ball
bearing hinges with grease fittings.
• The gate post should be secured in the ground with
concrete so it will minimize twist or flex when the
opener is activated.
• Make sure there is a stable area for mounting the gate bracket (this may require the addition of a horizontal or vertical
cross member).

Installation Overview for Pull-To-Open Gates
PUSH-TO-OPEN installation instructions begin on page 32.
The diagram shown below is an example of a pull-to-open installation on a chain link fence and single gate. Mounting
the opener on a masonry column may require special procedures. Furthermore, if you have a push-to-open gate,
you will need to purchase a push-to-open bracket [FM148] to properly configure your system. See Push to Open
Installation on page 32 before proceeding.

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.

14 Mighty Mule MM360 Installation Instructions
Installation of Mounting Hardware
We recommend you position the opener near the centerline of the gate to keep the gate from twisting and flexing
and to avoid back splash from rain water.
The Post Bracket Assembly
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.
On wood posts, place a metal plate or washer
(not supplied) between the nuts and the post
to prevent the thrust of the opener from pulling
the bolts and washers out of the wood.
The post pivot bracket may not be necessary
on posts larger than 6" in diameter. 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.

Install Post Bracket Assembly and Gate Bracket
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.
Step 1
Insert the 3/8" x 2" bolt through
the center hole of the post
brackets and post pivot
bracket as shown. Fasten a
3/8" washer, 3/8" lock washer
and 3/8" nut on the end of the
bolt. DO NOT overtighten
the nut because the post
pivot bracket will have to be
adjusted later.
Step 2
Attach post bracket assembly and gate bracket to the opener with the clevis pins and bushings. Secure the
clevis pins with hairpin clips.

NOTE: The following steps
are intended for pull-to-open
gate installations. If you are
mounting your opener on a
push-to-open gate (e.g., a gate
on a sloped driveway) you will
need to purchase a FM148. Also,
see Push-to-Open Installation
beginning on page 32.

Step 4
When you feel that you have the best position for the post pivot bracket in the open position, insert the 5/16" 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 2 inches of clearance or the gate opener is binding on the post pivot bracket, remove the 5/16" bolt and
readjust the pivot bracket until you can achieve these important clearances. Reinstall the bolt and related hardware as
shown in Step 1.
With the post pivot bracket in the optimum position for clearance and freedom of movement while maintaining 19 inches
or less on the stroke. 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.
If you are mounting to a post or column larger than 8" or you can not achieve the mentioned clearances, you can:
1) eliminate the post pivot to try and achieve the proper clearances.
2) install the unit as a push to open (bracket not included).
3) re-hang the gate within 4" inches of the back corner of the column.
NOTE: Re-hanging the gate, depending on the construction of a column, may require additional expertise and tools/
materials.
IMPORTANT:While determining the mounting point for the post pivot bracket assembly, be sure that the position allows
for minimum 2 inches of clearance between the gate and the opener in both the open and closed positions, as shown in
the diagrams below. This clearance will give the opener the most efficient leverage point for opening and closing the gate
and more importantly provides the least possible pinch area.
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.
