Thanks for that mickattwo, It’s handy to know another model with 22mm shaft when looking for rotor/tines. The F400 came with wheels but both thinner parts that separate are rusted out, I’m in no hurry for wheels so I will look out for some about the sales. I could bolt on or weld a suitable wheel to the drive centres from the old wheels. Took note of the bored bar could be another option.
