    Gate Opener Buying Guide

    To determine what type of automatic gate opener is right for you, ask yourself the following questions, and then refer to the chart below:

    • Do you have a single or dual gate?
    • Does your gate swing or slide? If your gate slides, contact your local Tractor Supply Co. store and ask about special ordering a sliding gate opener.
    • Does your gate swing into or away from your property?
    • How long is each gate leaf?
    • How much does each gate leaf weigh?
    • Is your gate within 1000 ft. of an 110V AC power source? If not, you will need to consider purchasing a solar panel to power your gate opener.
    • If your gate is longer than 18 ft. or weighs more than 850 lbs. per leaf; ask a team member at your local Tractor Supply Co. store about special ordering an automatic gate opener that can accommodate your gate type.

    Other Supplies You May Need for Installing a Mighty Mule Automatic Gate Opener

    Here are some other materials you may need for installing your Mighty Mule Gate Opener:

    • Low voltage wire (RB509) (16 gauge, multi- stranded, dual conductor, direct burial). Wire length depends on which accessories are used and the distance between the transformer power supply and the gate. [1000 ft. (304 m) max.]
    • If your gate is more than 1000 ft. (304 m) away from an 110V AC power source, Mighty Mule Solar Panels must be used to trickle charge the battery. The FM350, FM500 and FM502 are solar compatible.
    • If your gate opens out from your property, you need to purchase or special order a "push-to-open" bracket (FM148) through your retailer. Call 1-800-543-1236 for technical support. (dual gates require 2 brackets).
    • If you have thin walled tube or panel gates, you will need to reinforce them. See diagrams below for tips on reinforcing these types of gates.
    • Depending on the type of gates, a horizontal cross member or mounting plate may be needed to mount the opener arm and gate bracket to the gate.
    • Your gate must be in good working order, firmly hung on well seated fence post, and swing freely and evenly. This operator will not work on gates with wheels or gates that drag on the ground.
    • Gates weighing more than 250 lbs. (111.4 kg) require ball bearing hinges (not provided by Mighty Mule).
    • Gate post greater than 8” (20.3 cm) thick will require longer bolts than those provided to mount gate brackets to post. (Rule of thumb, gate post thickness plus two more inches.)
    • Gate post less than 4 inches will require reinforcement hardware; large metal washers or steel plates for each side of the post.
    • Masonry column installation may require special procedures.
    • Tools such as a power drill, open end wrenches: 3/8", 7/16", 1/2", and 9/16", 3/8" drill bit, hacksaw or heavy duty bolt cutters, slotted (flat bladed) screwdriver, Phillips head screwdriver, tape measure, level, wire strippers, and C-Clamps — (small, medium, and large)
