The very best in rotary mulching technology has been packed into the Stubble Master 500, a premium five metre cutting width machine targeted at high output farmers and contract professionals demanding high levels of quality and performance.

The shaft driven machine benefits from Spearhead’s unique six-blade Starcut blade system as standard which; when coupled with the efficient delta wing design of the cutting deck provides a chop and spread of the highest standard.

Much of the appeal of the Stubble Master 500 is that it has been built without any compromise, mirroring many of the principles seen in the machines much larger in size in the same range.

Featuring three rotors, each with heavy duty blade holders and six robust 13 millimetre thick spring steel blades – three high lift and three flat for extra mulching, the machine is capable of leaving a flail type finish to support a more efficient harvest operation and an improved yield.
