TO MAXIMISE WEED CONTROL
• Full ground disturbance starts at 63.5mm (2.5 inches). • Adjustment should be made to compensate for disc wear and concavity. • To improve weed control and for better soil disturbance. • Adjust lateral disc positioning. • Ensure machine is traveling in line. • Increase depth to cut. • Replace discs. • Cross working at 15 degrees off line gives better leveling and trash clearance.
BLOCKING IN EXCESSIVE TRASH
• Lower rear discs gang to drive better in soil. • Adjust angle of lift soil deflector to allow greater flow.
• Try reducing speed slightly. CLOGGING IN WET SOILS
• Raise working depth. • Raise front discs. • Give soil more time to dry out.
