Thank you SO MUCH Grumpy!
The info you have provided is invaluable.

Looks like I have my work cut out for a while checking that everything is as it should be.

It's a pity about the paint job which looks a bit more bodgy in real life than it does in the pictures. My main concern at the moment though is to get it functioning as well as possible so I produce a schmick lawn! ...maybe a proper restoration further down the track

When it comes to grinding the blades, can you point me in the right direction in SA?
