Hello Buniper and HT6
I do want to say something here.
HT6 is quite perceptive in that this does record Aussie ingenuity.
This is a classic example of that.
My guess is that this is a 1960s modification of a 1950s machine.
Chris, it's great that you have seen the historical value in this.
This post now forms part of the provenance for this unique mower.
It needs to be preserved as is (in my view).
Cheers
