The Stubble Master 1210 is a true ‘beast’ extending to 12.1 metre cutting width to deliver the world’s highest output rotary mulching machine suitable for the most demanding arable, aviation and military markets.

Targeted at modern farming practices, controlled traffic farming and large areas where output is of paramount importance the Stubble Master 1210 allows the effective covering of over 120 hectares per day.

The 1210 goes wider with an increase in rotors with seven heavy duty carriers again fitted with a combination of robust ‘angled’ 12mm thick spring steel blades and flat upper blades to ensure mulch quality.

Transport dimensions are maintained within the legal requirements with the machine folding down via an innovative folding mechanism that ensures that the outer wing folds over completely within itself to sit nicely on a robust stowing cradle..
