Thanks Bonnar_Bloke and Jack,

I thought that the appeal of all these mowers gaining traction in the past few years would have yielded more manufacturers getting these types of spares into the marketplace.

I will continue to hunt around and maybe hit up some businesses to see what is viable. Otherwise I will just have to get inventive in knocking something up myself. I do have one that is worn but haven't had a chance to see if it grabs when running yet :-)
