The XP row units from John Deere continue the tradition of superior performance in the field. The XP row unit will provide extra performance, extra productivity, and extra precision while providing extra profitability to the grower's bottom line.

At first glance, the XP row unit looks much like the MaxEmerge Plus row unit it replaced. The functional components appear to be the same, but they are not.

For the XP row unit, we took the field-proven design of the John Deere row unit and applied advanced manufacturing technology and world-class testing techniques to design a planter row unit that has increased strength and longer-wearing parts, plus is easier to service.

 
Ductile iron-cast shank

The shank of the row unit is the foundation of planter performance. All ground-engaging functions of the row unit radiate from it.

The shank must be a pillar of strength and must not bend or twist under load. The perfect seed furrow, precision seed spacing, and alignment of the closing systems all depend on the row-unit shank being rock solid. The row-unit shank must have the strength to plant in all field conditions, acre after acre, year after year.

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.
 

The row-unit head is also designed using the ductile iron-casting process. The row-unit head provides the mating joint between the row-unit parallel arms and the row-unit shank. It is also the upper attaching point for the seed meter and seed hopper. 

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.

Tru-Vee opener blades and bearings

Tru-Vee opener blades and bearings

One of the trademark capabilities of John Deere planters has always been the ability of the Tru-Vee openers to provide a perfect seed furrow acre after acre in all types of field conditions.

The XP row unit builds on this tradition with components that offer a longer wear life and reduced maintenance time, and provide value to the grower in reduced cost of ownership over the life of the planter.

The thickness of the Tru-Vee opener blades was increased from 3.0 mm to 3.5 mm with the introduction of the XP row units. This increased opener blade thickness will provide 20 percent longer wear life.
 
The XP row unit also provides better Tru-Vee opener bearings for longer life. The single-row bearing has been replaced with a double-row ball bearing, which provides up to three times the wear life.

To complete the world-class Tru-Vee opener assembly, the rivets that secure the bearing and hub to the opener blade are nearly twice as strong as previous rivets.
Depth adjustment on XP row unit

John Deere planters provide consistent seed depth control in all field conditions. Depth control is a function of the Tru-Vee openers, the downforce system, and the gauge wheel assembly.

The gauge wheel itself is made of durable nylon composition with a concave profile. This profile gently firms the sides of the seed furrow, ensuring a well-defined trench. The concavity also reduces rocks and residue being picked up and thrown onto the drive chains and row units, and helps to prevent rooster tailing of soil.

The bolt-through design utilizes an open bearing in the gauge wheel that allows an attaching bolt to pass through the wheel to the threaded hole in the gauge wheel arm. This simple bolt-through design provides for a positive attachment of the gauge wheel to the gauge wheel arm and allows quick removal of the gauge wheel for service.

Adjustability of the row unit is critical to good performance. XP row units are the most user-friendly, adjustable units in the industry.

  • More available downforce options than any row unit in the industry
  • Single downforce springs, non-adjustable, 90 lb of downforce
  • Double downforce springs, non-adjustable, 180 lb of downforce
  • Adjustable heavy-duty downforce, four settings, 0 lb, 125 lb, 250 lb, and 400 lb of downforce
  • Pneumatic downforce, infinitely variable from 0 lb to 400 lb of downforce

Rubber tire closing systems are used for most conventional, minimum-till, and no-till planting conditions. The spacing between the wheels is adjustable so the closing system can meet the needs of those who want to plant small seeds at shallow depths.

The wheels can also be staggered fore and aft to enhance residue flow. Four levels of spring force are available and are easily set with the integrated T-handle adjustment. A lower force spring can be obtained from parts, if a lower amount of force is required. 

Additional closing wheel options include:
  • Cast closing wheels, for tough to close conditions
  • Disk closing, for shallow planting depths
  • Drag closing, for crust-and-bake conditions
  • Closing wheel frame less wheels, for growers desiring to use aftermarket closing wheels
