John Deere's 2600 Series Disks offer different blade options for soil penetration and residue sizing.
    Cone blade
   
    Solid-spherical blade
   
    Cutout-spherical blade
   | Blade type | Cone blades (John Deere exclusive)  | 
      Solid-spherical blades | Cutout-spherical blades | 
| Recommended application | 
       
  | 
      
       
  | 
      
       
  | 
     
| Recommended soil type | Heavy soils | Light to medium soils | Heavy to medium soils | 
| Benefits | Move soil and reside freely, but also increase draft requirements | Better control of soil than cone blades since less sensitive to over speeding | Chopping or trapping residue | 
| Penetration | Penetrate well at a 20-degree gang angle, but best at a 22-degree gang angle | Penetrate best at a 20-degree gang angle | Penetration is excellent with a cutout blade | 
NOTE: Cone blades not recommended in rocky conditions.
The 2620 General Purpose Disk comes equipped with front and rear solid-spherical disk blades with 185-mm (7.25-in.) or 230-mm (9-in.) spacing. The primary blade size is 560 mm (22 in.) x 4.5 mm (0.177 in.)
 Available blade options for the 2620 are listed below.
    185-mm (7.25-in.) blade spacing
   
    230-mm (9-in.) blade spacing
   185-mm (7.25-in.) spacing, front and rear
230-mm (9-in.) spacing, front and rear
NOTE:
    Number 1 edge (outside bevel, outside grind)
   
    Number 10 edge (inside bevel, outside grind)
   
    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.
    Residue management
   As crop yields increase, so does the amount of residue after harvest. The John Deere 2620 Disk enables producers to prepare soil for planting.
Utilize the residue calculator to identity the optimal residue management solution to meet the customer’s needs.
    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.
