Mid Row Banders® or Mid Row Shanks™
Which Option is Right for Me?

The iconic Mid Row Bander® Fertilizer Applicator and the Mid Row Shank™III Fertilizer Applicator are leading options for one-pass seeding with each option having both their strengths and their challenges. These should be carefully considered by Producers when configuring the ideal one-pass system that will best meet their conditions and practices.
Like the MRB® Fertilizer Application System, the Mid Row Shank™ Fertilizer Application System is a viable option for Operators wanting to apply nitrogen and/or sulfur between every other seed row.
Operators interested in the MRS™III option should consider the following important factors when determining which option to select:

Field Residue
  • Mid Row Bander® Fertilizer Applicators employ a large coulter disk to cut through the residue and soil to incorporate fertilizer; this cutting action will help residue flow through the seed openers minimizing plugging.
  • Mid Row Shank™III Fertilizer Applicators are designed and arranged on the drill to optimize its ability to clear field residue, however, they cannot cut through managed field residue like the MRB®III can. With the MRS™III, extra care must be taken to ensure that field residue is properly managed, especially in heavy straw seasons.
  • The MRS™III is virtually maintenance-free, with no routine adjustments or greasing requirements.
  • The coulter hub of the MRB®III requires periodic greasing and the floating scraper must be adjusted to ensure ideal operation as the coulter wears.
  • Trip tension, as well as the "park" feature when not required, are set the same for both the MRB® and MRS™ Fertilizer Applicator options.
Field Finish
  • The downward cutting action of the MRB®III coulter creates a narrow furrow to place fertilizer and the retainer tine holds the soil down to help keep the soil structure intact as the disk moves through the soil. In addition, the seed openers maintain a consistent seed depth as the soil structure is more intact.
  • Narrow openers are utilized for Mid Row Shank™ Systems, but disturbance is still greater, resulting in a rougher seedbed, greater exposure to moisture loss, and, as well, the increased loose soil may require reducing your operating speed to prevent "stepping", or soil from a back seed row flowing onto the front seed row next to it.
Depth Adjustment
  • Depth adjustment on the MRB®III is relatively easy - plastic shims are added or removed to achieve the desired operating depth.
  • The Mid Row Shank™ Openers are adjusted by loosening and removing bolts on each assembly, so the MRS™ are not as convenient to set. The correct operating depth of the MRS is more critical than with MRBs as operating the MRS too deep will create excessive soil disruption.
  • 3335QDA drills with PLX™ openers, equipped with the AccuSet™ on-the-go depth adjust system allows Operators to change the depth of the MRB® or MRS™ fertilizer applicators independent of the seed openers.
  • The coulters of the MRB®III Openers act as keel, helping the drill to stay true behind the tractor.
  • Drills equipped with MRS™III Openers are not more prone to skewing than any other all-shank implement, but may be more evident as the shanks are mounted ahead of the seed openers.
