Adjust Unit Mounted Double Disk Fertilizer Opener

IMPORTANT: Verify fertilizer opener offset on every row before operating the planter. Improperly placed fertilizer has the potential to cause crop injury, depending on fertilizer product and application rate. Discuss fertilizer placement with the fertilizer supplier to determine the optimum offset for the rate and product applied.

Double-disk unit mounted openers perform in conventional, reduced, and light no-till conditions but are not recommended for double crop or tough no-till conditions. The double disk design limits penetration in tough no-till or double crop conditions. Single disk openers are better suited to no-till conditions.
