Lock scrapers in rigid position to prevent excessive blade wear when you work in light, dry soil. Or, set the scrapers in the self-adjusting position and peel away sticky soil. Either way, these scrapers direct soil and residue backward, rather than up toward the gangs where it can interfere with disking action. If you don't need the advantages of combination scrapers, you can choose optional rigid scrapers. Extra-long triple lips on the inner race team with a wide seal between the outer race and flange.
Bearings are greasable for long life.
Optional bearing-wear guards are recommended to reduce flange wear when you work in abrasive soil or need to disk deep. They are not recommended in rocky soil. Continuous-weld spools add protection. And the spool end caps match the blades to help prevent rocks from catching between blades. Gang angles are adjustable so you can match needs.
