The GTO RB741 Mighty Mule Gate Opener Remote (also known as Mighty Mule FM135) is a single-button transmitter designed to operate compatible GTO/PRO and Mighty Mule automatic driveway gate openers. Ideal as a replacement or spare remote, it provides convenient in-vehicle control for residential swing and slide gate systems and can also be used in light commercial settings. It pairs directly with most GTO/Mighty Mule control boards and can be added to other operator brands when used with the GTO RB709U universal receiver, making it a popular upgrade for mixed-system sites.
This transmitter operates on 318 MHz and is powered by a standard 12 V A23 alkaline battery. Programming is quick via the gate opener’s learn button on the control board—no dip switches required—allowing multiple remotes to be enrolled for single- or dual-gate operators. For best performance, program the remote at the control box and verify operation with the gate in full view. Compatible with a wide range of Mighty Mule and GTO/PRO models, this remote is a dependable replacement part for everyday use. For safety, keep transmitters out of reach of children and only activate the gate when the path is clear.
Compatible with GTO, Mighty Mule and Linear Pro Access gates and receivers that use 9 three position switches at 318 mhz. Contact Moving Up Garage Door Company to verify compatibility.
