Hi prd,

Oh dear- I have messed up. Thank you so much for advising on this.
There are a few shims and washers left over so I should be fine for those thank you.
Will fix it Saturday and advise.

Difficult to get pics of cutter clutch as I hadn't cleaned it up underneath yet. The previous owners grass still had it all clogged up.
Will get to that as well.
Thanks again for your help prd.
