Thanks for those details Max.
I'm OK with pulling things apart, only times I've had problems is when some ditz has used red Loctite or similar, but a bit of heat fixes that.
Last time that happened I nearly flipped an old Toyota Corolla onto its roof trying to undo a front wheel hub nut with a length of steam pipe and a three foot breaker bar with a 1 inch drive socket.
As said the carrier is firmly mounted now and the rest of the mower will probably fail before the boss/carrier connection does.
If necessary there's the remains of a Toro in a shed which has a tapered end on the drive shaft which fits into a boss with sensibly designed bar locating tangs, might have a go at tapering the end of this Corvette shaft if I can't find an easy replacement for this two eared thing.
