Item Information

The Mighty Mule RCK660 Automatic Gate Opener Rancher Combo Kit includes everything you need for a single swing gate opener installation. This easy to install battery operated low voltage system comes with an MM660 heavy-duty swing gate operator which can handle gates up to 18 ft. long or up to 850 lb. This gate opener can open a wide variety of gates from chain link and tube gates to wrought iron or ornamental gates. As long as your gate is level, plumb and swings freely on good hinges your gate opener should be easy to install in 2-4 hours. In addition to the single swing gate opener this kit includes a keypad and a total of four remote transmitters. No power at your gate? No problem! Just add a Mighty Mule solar panel (FM121 or FM123) to work your gate opener in most remote locations.

Mighty Mule RCK660 Automatic Gate Opener Rancher Combo Kit is rated 4.3 out of 5 by 35.
Rated 3 out of 5 by from Mighty mule! Well, this is the 2nd Mighty Mule open e on this gate. I have previously replaced: batteries, control boards and wireless re, I will see how this opener fares. Easy to install, but, we will see how it lasts. O have found mighty mule to be a little finicky...but the price is right. I like the approach of making it a "lot" including a couple openers and a keypad.

Rated 5 out of 5 by from I bought the 660 mighty mule great opener. Bought it, installation was very self explained. Main thing you have to have a very sturdy support post (in cement). This opener worked even after it sat in flood waters for five days.

I already have a single gate opener installed but we are wanting to extend our opening. Can I buy another single opener and sync them together to open and close both gates or should I just buy a dual gate package?

Asked by: Vickkie14
Vickkie14, Thank you for taking the time to post your question. We recommend you purchase a dual gate opener for your installation site. You would not be able to get 2 single gate openers to sync together correctly, to open in sync as they should. Thank you!

What is the operating frequency of the transmitters and receivers. My present system (that needs to be replaced) requires 300 MHz. Will they work with the RCK660?

Asked by: HLYSYS
HI, our remotes operate off of 318 MHz, but this kit does include 4 Mighty Mule remotes.

It rains a lot in olympia wa . how does the mule handle that ?

Asked by: tmac8320
Hi, our gate openers are meant to be used out doors and are designed to withstand the elements. If it rains a lot in your area, you may want t use the included transformer that can be plugged into a power source as opposed to using a solar panel to charge the battery.
