10 Mighty Mule MM360 Installation Instructions 
2. Check Direction of Gate Swing
The Mighty Mule Gate Opener is designed for PULL-TO-OPEN installations. PUSH-TO-OPEN installations require a 
Push-To-Open bracket [FM148, not included]. Push-to-Open Installation Instructions begin on page 32.
3. Prepare the Gate
• The gate must be plumb, level, and swing freely on its 
hinges.
• Wheels must NOT be attached to the gate. 
• The gate must move throughout its arcs without 
binding or dragging on the ground. 
• Note that a gate over 250 lbs. should have ball 
bearing hinges with grease fittings.
• The gate post should be secured in the ground with 
concrete so it will minimize twist or flex when the 
opener is activated. 
• Make sure there is a stable area for mounting the gate bracket (this may require the addition of a horizontal or vertical 
cross member).

Gate Grounding (recommended)
•  Shorter wire (6 AWG) is better, 1 to 2 feet recommended.
•  Bolt ring terminal at end of cable 4 - 6 inches above ground level.

NOTE: No grounding system absolutely protects against lightning 
strikes. If installed correctly, a grounding system will help minimize 
damage to your gate opener.
