MM260 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). The gate must not exceed 

12 feet in length or weigh more than 300 pounds 

(please see Technical Specifications on page x). 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 (800-543-4283).

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 12 feet or weighing 

more than 300 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.
