Double-Disk Fertilizer Opener

Double-disk openers will perform in conventional and reduced tillage conditions. They are not recommended for no-till or double crop field conditions where the double-disk design limits penetration ability.

Both the liquid and dry fertilizer attachments use the double disk opener.

The openers will place the fertilizer from 50 to 125 mm (2 to 5 in.) off row center. The opener will place the fertilizer from 100 to 150 mm (4 to 6 in.) deep, depending on soil conditions. The disks are equipped with self-lubricating anti-friction bearings.

The double-disk opener can be adjusted to two positions for light or heavy soil conditions. For light soils, place the spring anchor bolt (A) at top of slot (B) and for heavy soils, place the spring anchor bolt at bottom of slot.

To change spring position, raise machine, loosen jam nut (C) and turn spring anchor bolt until spring is loose, move bolt to desired position and tighten bolt and jam nut securely.

IMPORTANT: Be certain the adjusting bolt jam nut NEVER bottoms against the housing. Bottoming this nut against the housing restricts the pivoting action of the bolt, resulting in premature spring and/or bolt failures.

Insert stop pin (D) in opener hole (E) on rows 8 and 9 with dry or liquid fertilizer to prevent interference between the fertilizer opener at maximum upward travel and the fertilizer transmission input shaft.

The opener can be locked in a raised position when the fertilizer attachment is not being used, or for storage.

To lock the opener, proceed as follows:

(Not Illustrated) Raise the planter and place blocks beneath the openers. Remove the stop pin.

Lower the planter carefully with the openers resting on the blocks and install stop pin in locking hole (A), which is normally hidden by the mounting bracket.
