G'day Max, many thanks for that info.

I'll just mosey-on outside and do some exercise. Here it will
be my favourite "kick-a-few-things" I will do this with great gusto.
I will be humming Armstrong's 'What a Wonderful World ...
[Okay. did that, burnt some energy. and have calmed down...]
The only good thing about this episode was the humorous posts
by members made here.
Many thank to
Max for that link.
Unfortunately, I never made a complaint.
That it was said/claimed that this mower had HD parts is total BS.
Thanks
Gadge for the humourous take on band names. Brilliant.
Thanks to all for a great topic!
