   A - Depth Adjusting Handle

   Position each depth adjusting handle (A) at desired seed depth. With left-hand pin of depth adjusting handle (A) positioned in LOWEST hole and right-hand pin positioned in NEXT TO LOWEST hole, seed depth will be approximately 25 mm (1 in.). Each handle position changes the depth approximately 8 mm (5/16 in.). When adjusting seed depth, start with low opener down-pressure and gradually increase until desired penetration is reached. Generally the press wheel should carry some pressure. When opener hits a clod or high spot, wheel may temporarily lose pressure, but preset pressure will hold opener against soil surface.

2. IMPORTANT: Avoid machine damage. Initially, use low opener down-pressure and increase as necessary.

   Lower the openers while moving forward. Stop without raising openers.

3. Check to see if gauge wheel arms are up against depth adjusting handles.

4. NOTE: DO NOT use more down-pressure than required to maintain desired depth.

   NOTE: If openers over tire tracks are not penetrating soil adequately, adjust them individually. See ADJUSTING INDIVIDUAL OPENER DOWN-PRESSURE in this section.

   Adjust opener down-pressure as necessary until gauge wheel arms are against depth adjusting handles.

5. Check seed depth again, once the wheel arms are against the depth adjusting handles.
