G'day Mr Beefy,

As far as I know back then the engineers at the factory, they just built two machines:

The front-engine model (The Tractor)

The rear-engine model (The Mini / Mini-Mow)

The "Javelin" was just a name they slapped on.

This manual I think covers most of your model https://outdoorking-forum.com.au/fo...mber/624/filename/MiniTractor5and8HP.pdf
