Different blade options for soil penetration and residue sizing

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	Primary tillage Aggressive disking	Primary tillage Secondary tillage	Primary tillage
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.

Disk blade options

185-mm (7.25-in.) and 230-mm (9-in.) blade spacing available for 2620 Disk

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

Ideal for seedbed preparation and chemical incorporation
Provides limited residue-handling capability
Works best in light to medium soils

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 22-in. disk blades.

Easily tension disk gang bolts

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 enables operators to level disks from tractor cab

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 improve productivity

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.

Variety of residue managing solutions available

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.

Mechanical wing control increases frame levelness for five-section disks

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.
