How does the GTO Automatic
Gate Operator work?
Do GTO gate operators have soft start and soft
Yes, the Mighty Mule automatic gate opener series
FM500 and the GTO PRO professional grade gate
operators GTO PRO SW-2000XL, SW-2500, SW-3000XL,
SW-4000XL series and all have this advanced
feature. This will prolong the life of gate
hardware and gate operators.
How does the gate close?
Mighty Mule and GTO PRO Automatic Gate Operators
are fully capable of adjustable programming
to allow for the gate to close automatically
after reaching its fully opened position. If
you wish to have the gate close sooner than
that, push the button on the GTO entry transmitter
to activate the gate.
What happens if the gate hits something while
it is in motion?
The GTO Automatic Gate Operators have a built-in
safety obstruction sensor that once activated,
causes the gate to stop and reverse its direction
(much like a garage door opener). The sensitivity
for this safety feature is fully adjustable.
What if I DON'T want my GTO automatic gate
operator to close automatically?
To disable this feature, open the control box
and turn the dial until the 'auto close' is
off. On Mighty Mule series 500 and GTO/PRO SW-2000XL,
SW-2500, SW-3000XL and SW-4000XL series use
the dip switch
Will GTO's automatic gate operator hold the
gate tightly closed?
Depending on the length and type of gate, there
is a possibility that the end of the gate can
flex enough to allow a person or an animal to
enter. For maximum stability and additional
security, the GTO Automatic Gate Lock should
Can I lock my gate?
Yes. GTO's Automatic Gate Lock will lock the
gate and has a manual key as well.
Do you carry an automatic lock that is for
Yes. GTO has a product that will do just that.
It is called the Bulldog Pedestrian Gate Lock.
It does not require a gate operator to lock
a "walk-thru" gate. It can utilize
additional accessories such as digital keypads
for added security. It is wonderful for areas
around pools or daycare centers that need to
restrict pedestrian traffic.
Can I manually open the gate after I have installed
my GTO automatic gate operator?
Yes. All low voltage systems such as the Mighty
Mule automatic gate openers series FM350, FM500
and the professional grade gate operators series
GTO PRO SW-2000XL, SW-2500, SW-3000XL and SW-4000XL
series, in which the opener arm is mounted with
clevis pins. By removing the pin and clip at
either end, the opener can be removed and the
gate opened manually.
Can anyone remove my GTO automatic gate operator
by removing the clevis pins?
Yes. However, to avoid theft, add the Pin Lock
accessory on the front end of the swing gate
operator to ensure that only the homeowner can
unlock and release the opener. For adding pin
locks to slide gates and for more details contact

Transmitters and Receivers
Can I open my garage door opener with my GTO
Garage door openers use a different radio frequency
than the GTO Automatic Gate Openers do. If you
want your GTO entry transmitter to activate
both, you can purchase a special GTO garage
door receiver. The GTO garage door receiver
has the same frequency as the GTO Automatic
Gate Operator. If your gate and garage are within
close range of each other and you wish to have
one transmitter to do it all, then you can purchase
a two or three button GTO entry transmitter
that will operate the openers separately.
Can I open my GTO automatic gate operator from
my house with my GTO transmitter?
The normal operating range of the GTO entry
transmitter is 50 ft. to 100 ft. However, because
it uses a radio frequency and is subject to
interference by weather conditions, topography,
outside interference, etc., the actual range
may vary. If your house is within 1000 ft. of
your gate, you can place a second set of low
voltage wires in the ground at the same time
you are running wire for the transformer and
connect it to an unlit Push Button inside the
house. At the control box simply connect the
wires to the accessory terminal block.
Can anyone with a GTO transmitter be able to
open my gate?
Not if you personalize your transmitter code.
Every GTO entry transmitter comes with identical
factory settings, but you can personalize your
code by repositioning the dip switches inside
the GTO entry transmitter.
Can anyone open my GTO gate operator without
my GTO entry transmitter?
GTO offers a weatherproof Digital Keypad accessory
(for wired or wireless applications) which can
be mounted on a post near the gate. The keypad
can be programmed with up to 15 different entry
codes for use by family members, delivery personnel,
employees, etc. An additional security feature
is the ability to change only one code at a
time. For example, you can give a delivery person
an entry code and then that particular code
can be changed or eliminated after the delivery,
without affecting the other codes.
How does climate affect the
operation of an GTO gate operator?
GTO's Automatic Gate Openers are currently
in use from the Arctic to the Amazon. Because
of the battery's design, extreme cold may cause
it to operate a little slower than under normal
conditions and may malfuction. Therefore, in
extreme cold temperatures, we recommend use
of optional battery heater part # FM316 (Not
for use in solar powered applications)
Does lightning affect the GTO automatic gate
No electrical device can withstand a direct
lightning hit. However, GTO Automatic Gate Operators
have built-in ground paths on the control board
designed to diffuse mild static charges created
Just how are GTO and Mighty Mule automatic
gate operators powered?
All low voltage (DC) GTO and Mighty Mule automatic
gate operators are operated by a 12 volt, 7.0
amp-hour battery which also provides battery
backup during a power outage.
How many times will the GTO automatic gate
operator activate during a power outage?
On the average, a fully charged 12 volt, 7.0
amp-hour battery, will provide fifty (50) cycles
during a power outage. The number of cycles
may vary depending on factors such as the type
and size of gate, number of added accessories,
and weather conditions.
Can you install more than one battery into
the control box?
Yes, the Mighty Mule FM500 series and the GTO
PRO series SW-2000XL, SW-2500, SW-3000XL and
SW-4000XL have larger control boxes and are
pre wired for the optional second battery. This
is especially important for solar applications
for increased backup power supply.
Just how are GTO's batteries charged?
Each of GTO's (DC powered) Automatic Gate Openers
comes with a transformer that plugs into any
110/120 electrical outlet and provides a trickle
charge to the battery. The transformer is connected
to the control box with up to 1000 ft. of GTO's
16 gauge, multi-stranded, dual conductor, direct
burial, low voltage wire (not provided). If
there is not a standard outlet within 1000 ft.
of the control box, the battery charge can be
maintained with optional solar panel(s). If
an outlet is located outside, the transformer
should be placed inside a weatherproof electrical
box and connected to the control box with GTO
low voltage wire.
