Rated 5 out of 5 by from Makes life easier Bought it a month ago and it helps. My father is 82 and no longer needs to get down to open the gate.

Rated 5 out of 5 by from Really Nice I bought this automatic gate opener so my wife and I wouldn't have to get out our vehicles to open the gate and then get out to close it. It was relatively easy to install. We also bought the solar panel so we could charge a deep cycle battery to power the gate. Great investment.

Can your guests physically open the gate without a button? How does that work?

Asked by: Adrianna
Hi Adrianna, the only way to open the gate is either using a remote, keypad or push button control. You can also install a vehicle sensor but that will open when a large metal object drives through the sensor's path.

I have 2 questions. 1 does the transformer operate the opener without having a battery? I am looking at using this within 20 ft of a 110 power source and could bury the 12 volt wire.  2 how fast does a 12 ft gate open/ close?gpritch

Asked by: gpritch
gpritch, Thank you for posting your questions. The transformer is to be used in non solar panel applications, it will continually charge the gate openers battery (not included in this kit). A battery is required for operation, we recommend a 12V Automotive or Marine Type Battery that produces a minimum of 250 cold cranking amps (CCA). The approximate gate opening/closing time (90º) is 18 seconds. Thank you!

Would I be able to use the remote to open the gate from the house, which is about 300 ft. from the gate, such as when visitors are at the gate and I'm in the house or work shed?

Asked by: Gatekeeper too
Hi, our remotes are only rated for 100 ft. line of site. But some applications in rural areas without interference there is a possibility you could be farther from 100 ft. and be able to open the gate. If your remote does not work, we offer the Mighty Mule Push Button Control (Model # FM132) that is wired directly into the control board and can be wired up to 1000 ft. away from the gate.

Installed the opener with no problems but the gate opens on it's own for no apparent reason!!! Any suggestions for adjustments? We are not located on a major road but there are large trucks that do pass through once in a while.

Can you buy an extra remote, so my husband and I can both have a way to open the gate?

Asked by: Hawk211
Yes, you can add additional remotes for any of our operators. The part number for the remote is an FM135.

How is the battery charged if you do not use solar panel?

Asked by: Theresa Robinson
Hi, all of our Mighty Mule Gate Openers include a transformer (Model # RB570) that is used to plug into an outlet and charge the battery. If you do use the included transformer, we do not include the wire needed to wire the transformer to the control board. We recommend using 16 gauge, multi-stranded, dual conductor, low voltage wire that is UV treated & PVC coated that can be used for the transformer and our accessories. We offer this wire in three sizes: 100 ft. (Model # RB509-100), 250 ft. (Model # RB509-250), 500 ft. (Model # RB509-500) or 1000 ft. (Model # RB509).
