I'm putting a 6hp Kaw FJ180-CS09 (the "09" denotes tapered shaft for "Blade Brake Control") engine on an older Toro Commercial deck. The problem is I don't have the BBC assembly to go with it. Does anyone know of a simple keyed & tapered blade hub (spacer/adapter) that matches the tapered crank shaft outputs on the FJ180 BBC engines ? ..something that allows bolting the blade directly to the end of the shaft - circumventing the need to hunt down one of those costly and troublesome BBC units ? I could make a simple bushing to adapt a normal blade hub, but I'd like to do it right. -thx The Toro 22178, Metro 21 and JD commercials used the -09 taper shaft BBC FJ180's ..if that's any help.
