Sumo Strake

The Sumo Strake, a stubble rake designed to do more than your average lightweight straw rake.
The tungsten carbide tips, mounted on a powerful flat spring tine, used at speeds of up to 30kph are able to create a superior mix of soil and trash to get rogue seeds (including blackgrass) to chit.
The Strake also spreads chaff and chopped straw enabling less problems with the next pass, making drilling, cultivating or ploughing easier.
