Installation Guide
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 Specications 
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
