CAUTION: Always close the opener lock-up valve before servicing machine. If a hydraulic failure should occur while you are under machine, the openers would fall rapidly and cause severe injury or death to you or others.

Raising gauge wheel lowers seed depth for deeper planting; lowering gauge wheel raises seed depth for shallow planting.

Seed depth adjustment range is approximately 13 mm (0.51 in.) to 90 mm (3.54 in.) from deep (A) to shallow (B) settings. Generally, the second slot from the bottom end of adjustment range (25 mm; 1 in. seed depth) is used as a starting point. Each adjustment slot changes seed depth in 6.35 mm (0.25 in.) increments.

NOTE: Heavy field residue or worn disk blades may require use of a deeper setting to achieve desired seed placement.

To Adjust:

Pull handle (C) up, turn 45° and position in desired slot.
