Coulter Option Delivers High Speed and Low Disturbance


Case IH is equipping its Nutri-Placer 930 fertilizer applicator with new high-speed, low disturbance coulters the company claims will help the unit provide a superior field finish at speeds up to 11 mph.

At that speed, Case IH says operators can cover 510 acres in a 12-hour day for increased productivity, lower tractor hours and reduced fuel consumption. The new-look Nutri-Placer 930 made its debut at the 2017 National Farm Machinery Show in Louisville, Kentucky, last month.

In this video, Dave Long, Case IH’s fertilizer applications marketing manager, explains that the enhanced row unit found on the Nutri-Placer 930 fertilizer applicator – with high-speed, low disturbance coulters – is designed to maximize productivity and crop nutrient uptake.

Long adds that the new 22.6-inch single-coulter-blade design is key to a uniform field finish. It effectively cuts through residue with minimal disturbance, leading to improved soil and moisture retention that helps properly seal nutrients and reduce run-off. A four-degree blade angle opens a precise slot for accurate nutrient placement. Other features include:

  • A cast iron spring-loaded knife with carbide inserts for extended wear and protection of fertilizer tubes.
  • A wiper wheel that holds soil in place while the coulter opens a slot. It also eliminates soil and residue build-up on the coulter blade.
  • The closing system relies on the SharkTooth blade and walking tandem press wheel to firm the soil as the Nutri-Placer runs through the field. No-tools-required spring down force pressure and pivot range adjustments make changes quick and easy.
