This listing is for a flywheel fan.  It was removed from a Craftsman 15.5hp 42 inch lawn tractor model #917.272350 with a Briggs and Stratton model #282H07-0231-E1 engine.  The tractor pictured is the one this part was removed from.  It may fit other models as well.  Please confirm that this part will fit your mower before purchase.  It is in nice condition.  Payment by within 2 days of purchase.  I will combine shipping on multiple purchases when possible.  If you are looking for a part that I don't have listed please ask, I might have one.  Thanks for looking!
