2623 Three- and Five-Section Tandem Disks

Ground-engaging components on 2623

Three-section disk in transport

The John Deere 2600 Series offer three disk models that provide a wide range of variety for all tillage applications.

John Deere's 2600 Series Disks offer different blade options for soil penetration and residue sizing.

Cone blade

Solid-spherical blade

Cutout-spherical blade

NOTE: Cone blades not recommended in rocky conditions.

Disk blade options

• Disk blades compatible with 2620 Disk
• Disk blades compatible with 2623 Disk
• Disk blades compatible with 2625 Disk

The 2623 Dual-Purpose Disk comes equipped with front solid- or cutout-spherical blades and rear solid spherical disk blades with 230-mm (9-in.) spacing. The base blade size is 610 mm x 5 mm (24 in. x 0.197 in.).

Available blade options for the 2623 are listed below.

230-mm (9-in.) blade spacing

230-mm (9-in.) spacing, front and rear

• Good for seedbed preparation/chemical incorporation in medium to heavy soils
• Works well in primary tillage in light to medium soils
• Provides good residue-handling capability

NOTE:

• The number 1 edge has a beefier profile and is best for rocky conditions.
• The number 10 edge has a narrower profile and should work well in most non-rock conditions.
• Rear main and wing gangs are tapered with one blade 51 mm (2 in.) smaller than the primary blade.
• Integral furrow filler blades are included with all rear wing gangs which are 102 mm (4 in.) smaller than the primary blade.
• Front outer gangs have a taper that is 51 mm (2 in.) smaller than the primary blade, except for 560-mm (22-in.) disk blades.
• The John Deere 2623 offers customers a rollable blade option. Rollable disk blades support the
  edge-rolling practices that are commonly used. These blades can be rolled to restore the edge sharpness for customers needing a better penetrating blade.
• The special boron-composite material is capable of enduring the edge-rolling techniques without jeopardizing blade edge durability and longevity. John Deere does not recommend rolling disk blades that do not have this rollable designation.

50-mm (2-in.) disk gang bolts

Gang tension system

John Deere's 2600 Series Disks provide an innovative approach to tension disk gang bolts. 

Hydraulic fore-aft leveling

Hydraulic fore-aft leveling comes as standard equipment with John Deere's 2600 Series Disks. Operators can level the disk from the comfort of the tractor cab.

Sealed maintenance-free bearings (front view)

Sealed maintenance-free bearings (bottom view)

John Deere’s 2600 Series Disks feature a sealed maintenance-free bearing. A high-density polymer liner allows the bearing to dynamically align the shaft in rough field conditions. The bearing and high-density polymer liner sit inside cast housing. This cast housing was designed for strength and reliability as well as a built-in bearing wear guard.

These bearings increase productivity by reducing the amount of time needed to service the disk before operation and allowing customers to spend more time in the field.

As crop yields increase, so does the amount of residue after harvest. The John Deere 2623 Disk provides operators with a disk that can be set to prepare a seedbed for planting or set to bury and size tough residue in primary tillage applications.

Spring pack

Spring pack

John Deere’s mechanical wing control helps producers keep their frames level for five-section disks. Mechanical wing control is included in base equipment for all five-section 2600 Series Disks.

With this feature, a large spring is placed in the wing frame on each side of the disk. As the pivot point in the wing starts to raise, the spring presses against that point to keep the disk level through tough field conditions.

The red circles below illustrate the area of the disk where the large spring is place in the wing frame.

Mechanical wing control

John Deere’s mechanical wing control is an industry-exclusive feature. A five-section disk without mechanical wing control can show up to 75-mm (3-in.) of depth inconsistency across the wing frame.
