Hey thanks for the reply's.

I've watched the vids on taking the reel and bed knife out so that shouldn't be a drama to get them out and off to the sharpeners.
I don't get long to tinker with the mower before the Mrs works out that I've slipped into the garage ahah. Then mentioning the parts I need haha.. she'll lucky I didn't buy a brand new one.. So I'll get the parts and a sharpen when it's safe to do so haha.
I did the test that was suggested and when I pulled the lead the clutch body did have a bit of a wobble in it and isn't spinning true.
Probably have to look at replacing that?
cheers Trev
