DRIVE
• Low friction screw drive (linear actuator) rated for -5 ºF to +160 ºF (-19 ºC to +88.8 ºC).
• Powered by a 12 Vdc motor with integral case hardened steel gear reducer. Motor speed reduced to 270 rpm.
• Maximum opening arc of 110º. Approximate 90º opening time is 18 to 20 seconds, depending on weight of gate.
POWER
• 12 Volt, 1.2 Amp hour sealed lead acid battery. The charging circuit built in to the Mighty Mule 250 is designed for
the GTO battery. To avoid possible damage to the Mighty Mule 250 and the battery, ONLY use GTO replacement
batteries.
