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]. Push-to-Open Installation Instructions begin on page 31.
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).
