PART SIX 2016 Update - BASE & BLADE DESIGN
The full page advertisement (Part 1 above) makes a feature of the suction lift
design that causes grass and leaves to be sucked up and pulverized into a fine
fertilising mulch

Unlike the skirtless toecutter bases, the Rawco chassis base has a deep skirt -
essential to mulching mowers - in combination with short fluted blades for higher
tip speed and lift. The other ingredient is a restrictive rear discharge port,
which enables the mulching blade to re-cut grass clippings.

Because the Rawco had a rigid blade system, I think this machine was probably
fitted with a shock absorbing spring clutch in the round flange on the blade holder.

The alloy chassis appears to be a quality casting, and the fully enclosed
engine cowling gives the Rawco a modern streamlined style. To me, it is clear
that Wisely's Rawco was probably inspired by the British Rotorscythe County
(as were the Australian Ogden Rotamatic and Malvin). Of significance is that
all the Australian machines were manufactured in Melbourne. I do not believe
that is a coincidence at all.

Again, a sincere thank you to Bob for supplying the record with
such great photos of a significant - and rare - Australian mower.
