I have a chance to pick up a 12-14 but have no idea what the value is. Looks to be in working condition. Three phase, 5 or 7.5 motor. (can't find a info plate but it is BIG ) I have a 3 hp TEFC motor, 1 phase that I could put on it. Would that be enough motor for 12 or 14 inch blades? Thank for your input on these questions.
