Different blade options for soil penetration and residue sizing

John Deere's 2630 Series Disks offer different blade options for soil penetration and residue sizing.

Solid-spherical blade

Cutout-spherical blade

Blade type	Solid-spherical blades	Cutout-spherical blades
Recommended application	Primary tillage Secondary tillage	Primary tillage
Recommended soil type	Light to medium soils	Heavy to medium soils
Benefits	Better control of soil than cone blades since less sensitive to over speeding	Chopping or trapping residue
Penetration	Penetrate best at a 20-degree gang angle	Penetration is excellent with a cutout blade

Disk blade options

230-mm (9-in.) blade spacing available for 2633 Disk

The 2633 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 2633 are listed below.

230-mm (9-in.) blade spacing

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

Good for seedbed preparation and 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 2633 offers producers 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 producers needing a better penetrating blade.
The special boron-composite material can endure 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.

Gang tension system

John Deere's 2630 Series Disks provide an innovative approach to tension disk gang bolts.

Variety of residue managing solutions available

Residue management

As crop yields increase, so does the amount of residue after harvest. The John Deere 2633 and 2635 Disks provide 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.

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 2630 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 in the following image illustrate the area of the disk where the large spring is placed in the wing frame.

Mechanical wing control

John Deere 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.

Extended-life bearings improve productivity

John Deere 2630 Series Disks and Vertical Tillage Implements feature extended-life bearings. These more durable and reliable bearings allow producers to customize bearing maintenance for specific growing conditions and soil types.

The flange-mounted bearing and sealing system features improved contamination resistance. The advanced seal material is highly resistant to wear and damage caused by abrasive soils and other crop materials. The design of these is more durable and reliable than previous bearings.

The design of this bearing system allows for dynamic self-alignment to the gang bolt, as opposed to trunnion-mounted bearings that have limited alignment capability. This system features additional freedom of movement, accommodating a wider variety of field conditions. The bearing system has been designed to decrease stress and fatigue on the inner rolling surfaces, supporting extended bearing life.

The bearing and seal design allows for a limited, seasonal maintenance interval to minimize downtime. They also allow producers to customize the maintenance for specific growing conditions and soil types. The multi-lipped sealing system cannot be damaged by frequent greasing. It allows bearings to accept grease within the bearing as well as provide grease to the outer bearing surface to eliminate wear between the bearing and housing. With this design, the bearings can accept grease even if misaligned to the housing.

Multiple enhancements made to 2630 Series Disks

2630 Disk in the field

The 2630 Series Disks offer multiple upgrades and additional items as options versus the 2620 Series Disks to enhance the machine. Check out the following video to see more about the 2630 Series Disks.

Extended-life bearings

John Deere 2630 Series Disks and Vertical Tillage Implements feature extended-life bearings. These more durable and reliable bearings allow producers to customize bearing maintenance for specific growing conditions and soil type.

TruSet™ side-to-side feature

John Deere TruSet system is featured in base equipment for the 2630 Series Disks and Vertical Tillage Implements. TruSet side-to-side is also available and features individual section leveling.

Knife-edge hydraulic rolling basket

The hydraulic rolling basket is offered with a round bar or knife-edge. The knife-edge is best for heavier, wet soil, and can be used in rocky conditions.

Radial tires

The 2630 Series Disks and Vertical Tillage Implements feature radial tires for the mainframes in base equipment. Radial tires are available as an option on the wing frame and stabilizer wheels. These tires are designed to offer longer wear life and help minimize compaction with a wider plate and lower inflation pressures.

Stabilizer wheels

Producers can choose either mechanical stabilizer wheels or TruSet hydraulic stabilizer wheels as an option. Stabilizer wheels help to maintain a consistent, level depth and are recommended for operation on rolling ground. The mechanical stabilizer wheels can be manually adjusted with a turnbuckle. TruSet with side-to-side leveling capabilities also enables operators to control the TruSet hydraulic stabilizer wheels from the cab while on the go.
