Brilliant
Gadge!
I knew a 'farm boy' would know this!
Yes, sorry, the fingers were static. The sickle bar reciprocated.
I would like to add something on the
Whirlwind using sickle bar knife segments.
This is so true - and it seemed so logical. I guess the blades could have been
reversed as well.
However, I currently believe the British Hayter was the 'grand-daddy' of the
slasher mowers that influenced Australian designs.
The
Hayter rotaries - walk behind and tractor mounted sold here from
the early fifties (possibly before). These used sickle bar blades,
and
Whirlwinds were good Hayter copies.
