6. Install new spring (A) on bolt. NOTE: Be certain flat surfaces on plates are on top. 7. Install plates (B) removed from old spring. If fertilizer is not at desired depth, check the following before changing the depth adjustment: The gauge wheel is in contact, but not pressing into the ground. Readjust down pressure spring if necessary. The dry fertilizer spout is centered over the trench. Reposition spout if necessary. The dry fertilizer spout height is not set correctly for dry soil or windy conditions. Move spout downward until it is approximately 15 mm (5/8 in.) above the trench. In wet ground conditions, help prevent plugging by positioning spout upward until it is approximately 25 mm (1 in.) above the trench. |
