This is our largest model with strength to match. Cutting a massive 9.1 metres at once, large-scale farmers, plus aviation and military organisations, welcome its might.

This machine has every feature you need to deliver intensively at speed. It boasts our 225HP driveline for maximum power. And five rotors work 30 blades in our famous Starcut formation.

The monocoque design provides incredible strength coupled with sleek top and under decks. This reduces cleaning too as debris has nowhere to hide. You’ll look forward to hitching up the Stubble Master 930 HD.

  • Largest, top-end machine for intensive cutting.
  • Power forward with a 225HP driveline.
  • Performance boosting specification.
