It all starts with the ductile iron-cast shank. Ductile iron casting is a unique high-tech process that produces a single-piece row-unit shank that replaces the traditional 13-piece welded shank.
The properties of ductile iron castings are such that they deflect without bending, withstand great impact without cracking, and can be machined to close tolerances for precise alignment of mating components--perfect properties for a row-unit shank.
A ductile iron-cast shank is a foundation of higher quality and higher strength for a John Deere row unit.

Ductile iron casting of the row-unit shank and head assembly provides a row unit that is 25 percent stronger than welded row units.
Got rocky fields? The cast shank of the XP row unit is 50 percent stronger in a frontal impact situation. In tough no-till conditions, the increase of 7.5 lb of row-unit weight will assist the Tru-Vee™ openers in soil penetration.
In addition to strength, the cast shank also promotes better alignment of all row-unit components. The one-piece casting with its machined surfaces eliminates the variable tolerances associated with welded assemblies. Properly aligned components not only function better in the field, they also have a longer wear life.
The lower portion of the XP ductile iron shank incorporates a bayonet-style mount for the seed tube guard, offering greater ease of service. Simply slide the guard onto the bayonet mount with a quick twist and lock to attach the guard. Once the opener blades are in place, the seed tube guard is in position, ready for the seed tube.
