Depending on the model, single-disk or double-disk frame-mounted fertilizer openers options are available to meet a wide range of operating conditions. The single-disk frame-mounted fertilizer opener is the most robust and versatile of the two frame-mounted options. 
 
There are two designs of frame-mounted single disk fertilizer openers available for planters today:
  • One design mounts to rigid frame or folding planters and utilizes a steel upper arm for secure mounting.  This style opener is shown in the right-hand picture above and has been available for a number of years. 
  • The second design of frame-mounted single-disk openers is strictly for 7-in. x 7-in. frames and is for use on the 1770NT, 1770NT CCSTM, and 1790 Planters (excluding the 24Row20). This design incorporates a longer curved upper casting and is shown in the left-hand picture above.
 
Single-disk fertilizer openers feature a gauge wheel to:
  • Gauge fertilizer application depth
  • Minimize soil disruption

The frame-mounted, single-disk opener has the ability to be locked up in the raised position on 1790 Split-Row Planters. This eliminates excessive wear to the openers when planting soybeans with a 1790 and the openers are not utilized. There are two bundles required for updating 1790 Split-Row Planters. One bundle is used for the center frame section and the other bundle is for wing sections. 

The frame-mounted, single-disk opener cannot be locked up in the raised position on 1770NT Planters due to frame tube and opener contact. The steel opener for rigid or folding planters (non-NT) can be raised somewhat by screwing up the spring assembly but cannot be completely raised from the soil. 

NOTES:

1) Single-disk openers on 8Row30 1750 frames are limited to placement of 3 in. to 6 in. off the row on rows 4 and 5. 
2) Single-disk opener is not recommended for loose, soft soil conditions unless equipped with cast spout. 
3) Single-disk opener has optional heavy-duty spring A50733 (Parts) if more down force is needed in tough no-till conditions. 
4) Double-disk opener is not compatible with frame-mounted coulter.
NOTE: Order number of opener bundles to match number of planter row units, i.e. 4Row 1750 Planter requires four BA91211 double-disk openers or two BA91212 single-disk openers. (The only exception is for front-fold planters. Correct quantity of opener bundles is shown in parenthesis after the bundle number in notes below.)
