8 Mighty Mule MM360 Installation Instructions 
MIGHTY MULE 360 GATE OPENER
_____________________________________  
DRIVE 
 _____________________________________
  •  Low friction screw drive (linear actuator) rated for -5 °F to +160 °F (-20 °C to +71 °C). 
  •  Powered by a 12 V motor with integral case hardened steel gear reducer. Motor speed reduced to 260 rpm. 
  •  Maximum opening arc of 110°. Approximate opening time (90°): 18 seconds, depending on weight of gate.
_____________________________________
 POWER 
 _____________________________________
  •  The system is powered by a 12 Vdc automotive or marine battery. 
  •  Battery charge is maintained by a 120 Vac, 18 Vac output transformer (40 VA) through the GTO control board or 
by optional GTO Solar Panels; the panel should generate minimum of 5 Watts at 300 mA. IMPORTANT: Never 
use both transformer and solar panel— this will damage the battery and control board.
  •  One (1) blade-style 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.

 CONTROL 
 _____________________________________
  •  GTO DIP switches are set for single leaf, pull-to-open gate installations. DIP switches can be adjusted to 
accommodate push-to-open gates.
  •  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 RF Receiver tuned to 318 MHz. 
  •  Opener length with push-pull tube fully retracted is 37 
1
/4", mounting point to mounting point. Maximum stroke 
 is 19".
  •  Adjustable auto-close timer (OFF to 3–120 seconds), and Dual Sense Technology stall force.
  •  Power terminal block accommodates a transformer or solar panels.
  •  Accessory terminal block fully compatible with all Mighty Mule access controls.
  •  Control board allows connection of edge sensors and photoelectric 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 12 Volt battery 
depleting to a state where the unit will not function. This chart reflects a Mighty Mule Automatic Gate Opener when 
charging with a transformer and 12 Volt battery. Actual cycles may vary slightly depending upon the type and 
condition of gate and installation.
    NOTE: BALL BEARING HINGES SHOULD BE USED ON ALL GATES WEIGHING OVER 250 LBS.
    To determine the number of cycles the gate opener will perform using solar panels (see page 9)
* These specifications 
are subject to change 
without notice.
An operation cycle is 
one full opening and 
closing of the gate.
