The very best in rotary mulching technology has been packed into the Stubble Master 500 to deliver exceptional output and performance at a compact five metre cutting width.

Targeted at modern farming practices and contract professionals demanding high levels of chop quality the machine benefits from Spearhead’s unique six-blade HD6 cutting system as standard which; when coupled with the efficient delta wing design of the cutting deck provides a cut and spread of the highest standard.

Most notable is the flat upper deck surface that allows much easier cleaning. This beneficial feature is not however at a cost as the flat underside cutting deck is also maintained through an innovative monocoque style deck design.

The Stubble Master 500 features three rotors each with heavy duty blade holders and a combination of robust ‘angled’ 12 millimetre thick spring steel blades and flat upper blades to deliver a mulched finish.
