The Best Mighty Mule Gate Opener of 2020 Reviewed

The weather is bad – terrible, really. But you have to get out of your car to open the gate to your property so you can drive in. Wouldn’t it be great if you could open that gate without going out into the cold or the wet? You can with a Mighty Mule gate opener that automatically opens the gate for you from the comfort of your car or truck.

For pretty much the same reasons as you have a garage door opener, you should have a swing gate opener too. Mighty Mule makes some of the best in the market. We’ll take a look at four models here that are designed for single swing gates. (Mighty Mule does make openers for other styles of gates too.)

Common Gate Opener Features

Before we look at the individual models of each Mighty Mule gate opener, let’s take a peek at the features that are the same for all of them.

We already mentioned the most important item which is that these are single swing gate openers. Related to that is the fact that these openers all pull your gate inward, towards your property.

Other models can handle dual gates and push-to-open gates.

Each gate opener has adjustable obstruction sensing safety feature which allows it to stop and reverse direction within 2 seconds of contact with any significant obstruction.

Mighty Mule openers have an auto-close feature that you can adjust or turn off. It allows you to set the gate to remain open for up to 2 minutes time. If you don’t want to wait for the auto-close to kick in, you can press the button on the remote a second time to shut the gate immediately.

For most of these Mighty Mule gate openers, you will need to purchase (assuming you don’t already have one) a 12 volt battery. This can be either a standard automotive or a marine type battery. You’ll need to house this battery in a weather-proof case within six feet of your gate.


#1: Mighty Mule MM260 Light Duty Single Swing Gate Opener (Best Value – All Purpose)

What makes the Mighty Mule MM260 a “light duty” opener is the size and weight of the gate it can handle. The maximum length of your gate can only be 12 feet, or the weight can only be up to 300 pounds.

In the package, you get the following items.

  • Mounting hardware
  • Transformer
  • Transmitter
  • Installation manual and DVD
  • Opener arm
  • Control box with built-in receiver

If you have trouble installing any of these gate openers yourself, Mighty Mule has a great customer service department – available any time of day or night – that can help you along the way.


#2: Mighty Mule MM271 Automatic Single Swing Gate Opener (Best For All Gate Types)

Like the MM260, the Mighty Mule MM271 opener is another light duty device. (It seems that all the MM2xx models are light duty machines.) As such, your gate must again be 12 feet long or weigh 300 pounds at most.

Mighty Mule suggests that these openers are “perfect for all single gate types including ornamental, chain link, tube, panel, vinyl, and wood.” So this would be a great match no matter what style of single swing gate you own.

The MM260, this MM271, and the MM371 below are all backed by Mighty Mule’s 12 month warranty. You can contact Mighty Mule at any time during your first year of ownership regarding problems and for technical support.

The MM271 gate opener is “solar capable”, meaning you can add Mighty Mule’s 10-watt solar panel (Model #FM123) for help in keeping the battery charged.

In this package, Mighty Mule gives you the following.

  • MM271 Gate Operator
  • Remote with Visor Clip
  • AC Transformer
  • Mounting Hardware
  • Instruction Manual

#3: Mighty Mule MM371W Automatic Single Swing Gate Opener (Best Open & Close Speeds)

The MM371W gate opener is similar to the MM271 in that you get the same types of items in the package.

  • MM371W Gate Operator
  • Remote with Visor Clip
  • AC Transformer
  • Mounting Hardware
  • Instruction Manual

There are several significant differences though. First, you can have a gate that is up to 16 feet long or that weighs up to 550 pounds. Both of these measurements greatly increase your options, if you’re installing a gate for the first time. (Note that there is no requirement that your gate must meet these maximum measurements. It can be smaller.)

Even at this medium-duty level, you still need to supply your own 12V battery separately.

With the addition of the MMS100 Wireless Connectivity Kit, you can control your gate opener from anywhere using the smart phone app. We assume that the “W” in the model name refers to this wireless capability.

Also, by adding the same #FM123 solar kit mentioned above, you can take advantage of the sun’s power to charge your battery.

With the MM371W, you also get Mighty Mule’s 12-month warranty and technical support.


#4: Mighty Mule MM571W Heavy Duty Smart Gate Opener (Best Overall – Smart Machine)

The MM571W is near the top of the line for Mighty Mule single swing gate openers. It can handle a gate that measures up to 18 feet long or weighs up to 850 pounds.

If you add the appropriate kits, you can make this opener wireless and use the phone app as well as solar powered. (The kits are the same as the ones we told you about earlier.)

An additional benefit at this level is that Mighty Mule extends their warranty from 12 to 18 months. This is a reflection of the higher quality of the MM571W gate opener.

A final extra is that Mighty Mule includes a 12 volt battery, so you don’t have to locate one on your own. This bonus is reflected in the list of packaged components below.

  • MM571W Gate Opener
  • Remote with Visor Clip
  • 12 Volt Battery
  • Additional Backup Battery Box
  • Mounting Hardware
  • Instruction Manual

Final Verdict about the Mighty Mule Openers

All of these gate openers are sturdy, well-made machines. Which one you decide to get will largely depend on the size of your gate – either its length or weight or both.

Beyond that, if there is a special feature you want, such as the wireless capability (which can work from up to half a mile away), you may have to step up a level to acquire it.

Most current users are satisfied with their purchase of a Mighty Mule. Those few that aren’t probably should have done a little more research like you’ve just done.
