MOTOR for AutoTrickler/AutoThrowThis stepper motor is compatible with an AutoTrickler AutoThrow of any version. If you have a problem and you motor isn't running correctly, the problem is most likely not the motor itself. The motors themselves fail very rarely and the problem is more likely the motor cable. Do not source a stepper motor from another vendor and try to use it with the AutoTrickler or AutoThrow. Using the wrong specification motor could damage the electronics.
