LATERAL FRONT DISC GANG POSITIONING

The Disc positioning system is used for maximum soil disturbance, reduced ridging and weed control. Adjustment can also be made to compensate for disc wear. ADJUSTMENT PROCEDURE *NB - Be sure machine is tracking in line before attempting to make this adjustment. See pg 28 • Start with factory settings. Pg 30 • To remove any ridges, test run at normal operating speed and stop quickly. • Check for ridges of undug soil. Follow ridges into machine and identify which direction to adjust (see diagrams on this page). • Only adjust front sideways in small increments ½” or 12mm • Re-check in hard soils as jump arms tend to flex more.
