Please Read This First!

Thank you for purchasing a Mighty Mule® 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 DVD will 

enable you to properly install your Mighty Mule® E-Z 

Gate Opener. 

The Mighty Mule® E-Z Gate Opener 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® E-Z Gate 

Opener 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® E-Z Gate Opener can 

be used on vinyl, aluminum, chain link, farm tube, 

and wrought iron gates. Use on solid (wood) 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. 

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.

PLEASE 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

Systems line of gate openers and accessories. Our

overview of the installation procedure. You must read the installation manual for detailed  

instructions on gate opener safety and proper use of the gate opener.
