Ideal for farmers and contractors who need a compact machine, the Stubble Master 500 provides a perfect balance.

Cutting five metres in one pass, it charges through your stubble – three rotors each handling six blades. Clever angles flare the material and promote faster decomposition.

Stubble Master boasts a monocoque structure. With an enhanced weight to strength ratio, it absorbs impact while improving fuel efficiency.

  • A compact workhorse to support farmers and contractors.
  • Angled blades speed up decomposition.
  • Easy cleaning thanks to flat upper (and under) deck.
