Thanks for that Darryl, I didnt realise that 22 was the model. I will mesure the deck tonight to work out the width, it is only a little one though, Whitch is proving hard to find a disk i can adapt to, I'll keep diging though.
I'm going to make something up to suit the fuel cap for now, I imagine it will be a while till the right one presents itself.
Grumpy, The Lawncub has the same one (its the non-painted pic) however in some pictures I have of other lawn cubs, there was a straight through one used, i think the pictures are up in the lawn cub's thread.
