I have been looking for the 'gator' type blades for my FW15 and have had no luck. I'm not interested in true mulching blades, just want some with teeth on the trailing edge to help shred leaves this fall. I've tried Oregon Gator Blades, Fisher Barton Eliminators and Ballard Rippers and none of the those make them for the FW15. If anyone has any idea where I might find a pair, it would be greatly appreciated. Thanks in advance.
