The Mighty Mule®
350 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 (FM148), 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 8
feet and 550 pounds or exceed 16 feet and 150 pounds . 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
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 p,orque at 12 V.
Maximum opening arc of 110º. Approximate opening
time (90º): 18 seconds, depending on weight of gate
The system is powered by a 12 Vdc automotive or marine
Battery charge is maintained by a 120 Vac, 18 Vac output
transformer [rectified to 14.5 Vdc (40 VA) through the
GTO control board] or by optional GTO Solar Panels [the panel
should generate minimum of 5 W at 300 mA]. A
diode on the control board prevents battery discharge.
IMPORTANT: Never use both transformer and solar panel - this
will damage the battery and control board.
One (1) blade-style control board fuse is rated for 15
NOTE: The transformer should not be directly connected to any
battery. Do not replace fuses
with higher ampere rated fuses; doing so will void your warranty
and may damage your control board.
GTO microprocessor-based control board is set for single
leaf, pull-to-open gate installations. DIP switches can be
adjusted to accommodate an optional kit for push-to-open gates
(see Accessory Catalog).
Control board has temperature compensated circuits.
A circuit on the control board regulates charging.
"Sleep draw" is 25 mA; "active draw" is
2 to 5 A.
Auto-memorization of digital transmitter code.
GTO remote-mounted RF receiver tuned to 318 MHz.
Opener length with push-pull tube fully retracted is
371/4", mounting point to mounting point.
Adjustable auto-close timer (OFF to 120 s), and obstruction
Power terminal bock accommodates a transformer or solar
DIP switches simplify setup of gate opener.
Accessory terminal block fully compatible with all
Mighty Mule access controls.
Control board allows connection of safety edge sensors
and photoelectric sensors.
Audio entrapment alarm sounds if unit encounters an
obstruction twice while opening or closing.
The Gate Capacity Chart shows approximate cycles, per
day, you can expect from the Mighty Mule 350 Automatic
Gate Opener when powered with a transformer. Actual cycles may
vary slightly depending upon the type and condition
of gate and installation.
