Here is the reply from Tow-N-Mow:
"It is not one of ours, although a similar concept. Our early ones were
green, however the deck was much the same as our current shape.
"Our slashers are made in Geelong and have locally machined components.

"We manufacture small volumes of very high quality slashers.
"Please see our webpage for further information or feel free to call the
office if you have any questions.
Kind regards"
Courteous of them to reply so quickly, but I'm bewildered by how the two types of slasher could be a "similar concept", except you tow them and they are self-powered with rotary cutters.
