G'day Max
This brings back memories of very unusual mowers.
The Everyman reels are best known; the Hercules rotary gets little mention.

Not too many makers were doing larger domestic rotaries in the late 1950s / early 1960s.
The Alex Grahame 21" Automower springs to mind; then the 20" A-V Hercules.

The surprise for me was your finding the patent for the Adaptamatic.!
I will see if I can get that into the History Record. Fantastic! - and we have
inventor names - Cyril Clifford Fogg and Harold Patrick Sinclair.
[Cyril and Harold are not popular names today grin]

Many thanks - again - for adding to the record on AUS lawnmowers.

I attach a significant ad on the Hercules' release.
Note the 'Teflex cantilever cutter bar' on the Hercules ...
meaning that bar blade holder (in your images) appears original!

Cheers
