When you go into a greenhouse and hear the high pitched squeal of fan belts, you are listening to the sound of dollars being sucked out of the house. Manually keeping belts tight is a never ending job- an automatic belt tightener is absolutely necessary.
The bottom line? Saving on your electric bill and reduced maintenance (no more belts to tighten) for a very small capital outlay.
