NOTE: “NR” indicates this size
and weight combination is not
recommended for the
Mighty Mule 660.
NOTE: Ball bearing hinges
should be used on all gates
weighing over 250 lb.
To determine the number of cycles the gate operator will perform using solar panels (see page 23).
* An operation cycle is one full opening and closing of the gate.
These specications are subject to change without notice.
DRIVE
• Low friction screw drive (linear actuator) rated for -5 ºF to
+160 ºF (-20 ºC to +71 ºC). Use of heater bands on arm and
control box will enhance performance in extreme cold tempera-
tures.
• Powered by a 12 V motor with integral case hardened steel
gear reducer. Motor speed reduced to 260 rpm. Generates 680
ft. lb. of torque at 12 V.
• Maximum opening arc of 110º. Approximate opening time
(90º): 20 seconds, depending on weight of gate.
POWER
• The system is powered by a 12 Vdc, 7.0 Ah, sealed,
rechargeable acid battery.
• Battery charge is maintained by a 120 Vac, 18 Vac output trans-
former. One lade-style control board fuse is rated for 15 A.
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.
• OPTIONAL: Battery charge is maintained by GTO Solar Panel
Charger Kit (5 Watt minimum).
CONTROL
• The Mighty Mule 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).
• 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.
• Operator length with push-pull tube fully retracted is
40-1/4” mounting point to mounting point. Max stroke 20”.
• Adjustable auto-close timer (3 to 120 s), and Dual Sense Tech-
nology Stall Force.
• Power terminal block accommodates a transformer or solar
panels. NOTE: Do not use solar panel and transformer at
the same time.
• DIP switches simplify setup of gate operator.
• Accessory terminal block fully compatible with push
button controls, digital keypads, loops, etc.
• Control board allows connection of edge sensors and photo-
electric sensors.
• Audio entrapment alarm sounds if unit encounters an
obstruction twice while opening or closing.
OPERATIONAL CAPACITY
• The Gate Capacity Chart shows approximate cycles, per day,
you could achieve prior to the battery depleting to a state where
the unit will not function. This chart reects a Mighty Mule
Automatic Gate Opener when charging with a transformer.
Actual cycles may vary slightly depending upon the type and
condition of gate and installation.
