John Deere 2330 mulch finisher

Three-section configuration

Five-section configuration

At 16-km/h (10-mph) working speeds, the 2330 Mulch Finisher can cover up to 27.5 ha (68 acres) per hour enabling producers to size their implements for their unique productivity and agronomic needs.

The 2330 is available in sizes ranging from 6.6 to 17.2 m (21 ft, 9 in. to 56 ft, 3 in.). Horsepower requirements range from 24.5 to 34.2 kW/m (10 to 14 hp-ft), depending on the soil, depth, and speed.

T-hitch with Level-Lift turnbuckle

Level-Lift turnbuckle

The Level-Lift hitch ensures a level operation through all operating depths. It also provides consistent gang and sweep depth fore to aft for thorough seedbed preparation. This quick, easy adjustment ensures a flat seedbed floor and level soil profile for planting.

The combination of the disk gang, sweep, and harrow functions promotes consistent and uniform chemical placement and mixing. The T-hitch enables easy turnbuckle adjustment for fast tractor changeover and quick implement leveling fore to aft.

The heavy-duty T-hitch allows for tighter turning, decreasing the number of headlands required for quick turns on the end. The T-hitch also houses the hoses and wiring harness, protecting them from crop and incidental tire contact.

Low-concavity disk blades

Disks engaged on 2330

The producer can work ground faster with the 508-mm x 5-mm (20-in. x 0.197-in.) low-concavity disk blades and outside blades tapered to 457 mm (18 in.) on the 2330 Mulch Finisher"

• Allows aggressive cutting action
• Minimizes ridging

Blades are spaced 184-mm (7.25-in.) apart and are fixed at an 8-degree gang angle:

• Results in effective slicing in heavy residue
• Moves the soil inward toward the center of the implement for a level seedbed

C-spring cushion gangs help protect against rocks and other obstructions in the field. Dura-Flexâ„¢ (3+1) bearings are standard equipment:

• Triple lip on the inner race and a wide seal between the outer race and flange prevents soil from entering between the bearings and flanges, and helps retain lubrication in the bearings
• Greaseable for long life

All disk gangs feature combination rigid/self-adjusting scrapers as standard equipment:

• Prevent soil buildup on inside of disk blades
• Adjustable to compensate for wear
• Self-adjusting operation—the spring tension helps hold the scrapers against the disk blade in sticky soil conditions

Engaged disk gangs add to the stability of the implement at higher ground speeds for consistent working depth in uneven ground.

• Allow for good weed kill and tilling
• Provide excellent chemical incorporation

229-mm (9-in.) spacing

Thanks to an updated frame design that enables true 229-mm (9-in.) split-the-middle shank spacing, the 2330 Mulch Finishers can maintain consistent depth and evenly cover the field to achieve an optimal seedbed while flowing residue and managing weeds.

Seedbed preparation

Even at high speeds and in tough field conditions, the TruPositionâ„¢ C-shanks with 91 kg (200 lb) of trip force minimize side-to-side movement and provide the operator better control of the soil profile for improved leveling capabilities.

These shanks provide a full tillage cut across the entire width of the implement. The shanks stay firmly planted in tough soils without quickly relieving. As a result, the soil is mixed completely and streaks are reduced. This helps producers maximize their productivity and create flat seedbeds for smooth planter operation and consistent seed depth.

Weed management

The even 229-mm (9-in.) split-the-middle shank spacing enables the 2330 Mulch Finisher to minimize the potential of remaining strips of weeds that survive the tillage pass. With a mulch finisher pass just prior to planting/seeding, the crop can emerge into a weed-free field that gives it the best chance to reach canopy ahead of the weeds.

If some weeds emerge and a post-emergence herbicide is needed, weeds should be smaller and easier to control. As a result, the mulch finisher pass helps keep weed management costs under control and helps preserve crop yield potential.

TruPosition standards

TruPosition standard components

Producers are working ground at faster speeds and in tighter soil conditions, requiring more from standards and frames.

The 91-kg (200-lb) trip TruPosition standards include:

• Heat-treated mounting bracket
• Cast pivot assembly with front stop
• 19-mm x 45-mm x 610-mm (3/4 x 1-3/4 x 24-in.) C-shank, retained by a bolt through the casting and U-bolt—ensures consistent sweep depth, level seedbeds in all secondary conditions, and thoroughly incorporated chemicals
• 610-mm (24-in.) underframe clearance provides extra room for excellent residue flow on 229-mm (9-in.) spacing
• 254-mm (10-in.) trip height (at shank) clears rocks and obstacles
• Replaceable split-tension sleeve and chrome bushing extend life of standard and implement

These standards provide 91 kg (200 lb) of trip force and enable producers to maintain a consistent sweep depth. A combination of spring pressure and pivot casting geometry minimizes side-to-side movement and provides the ultimate in soil profile and seedbed.

Bolt-on and knock-on sweep options are available to customize the 2330 Mulch Finisher to perform well in a variety of field conditions.

The John Deere high-productivity sweep options are recommended for the high-working-speed market and perform best at speeds of 11-16 km/h (7-10 mph). With a low profile and curved wing shape, the high-productivity sweeps provide low draft and consistent penetration while easily getting through tough and heavy residue. Compared to Tru-Width sweeps, high-productivity sweeps are designed to exert less draft and retain their shape for longer wear life so producers can stay productive in the field longer.

The high-productivity sweeps for the John Deere 2330 Mulch Finisher come in a 254-mm (10-in.) width, both in the bolt-on and the knock-on Perma-Loc version. They fit all 47-degree standards with 44-mm (1.75-in.) hole spacing and 11 mm (0.4375 in.) that currently take Tru-Width sweeps, both John Deere and other makes.

Bolt-on sweeps

Tru-Width sweep

High-productivity sweep

254-mm (10-in.) Tru-Width sweeps are optional on mulch finishers with 229-mm (9-in.) shank spacing.

The Tru-Width design offers the following benefits:

• Maintains full cutting width and point through the life of the sweep
• Gives greater wear life and improved performance over regular sweeps
• Provides superior scouring and penetration
• Works soil well for level seedbed and good seed-to-soil contact
• Gives excellent chemical incorporation
• Wears evenly and pulls easily
• Replacement without charge if breakage occurs before appreciable wear

Knock-on sweeps

Perma-Loc sweep

High-productivity Perma-Loc sweep

Perma-Loc utilizes a self-tightening ratcheting system for easy installation. Indentations formed in the sweep stem provide the spring clip with a locking surface. The adapter edge, sweep, and spring all act together to tightly lock the sweep to the shank. The operator simply pushes the sweep on by hand to the first notch (audible click). As the resistance is increased (ground engagement), the sweep progressively wedges tighter. The mounting design minimizes lost sweeps and wear on adapter.

Utilizing the removal tool to depress the spring through the stem access opening and a tap with a hammer easily releases the sweep from the adapter and spring.

Perma-Loc sweeps have the advantage of using a Tru-Width design for penetration, residue flow, and long life. The proven 47-degree sweep angle minimizes soil slabbing yet promotes soil movement. The narrow stem enhances excellent soil and residue flow. Stem geometry ensures soil flow over the spring access opening, effectively separating and lifting flow to a point higher on the shank. The force of soil flow is reduced on the shank, improving shank life.

The Perma-Loc system is standard equipment and consists of the following:

• Adapter
• Spring hardware
• Sweep
• Removal tool (separate option on field cultivators)

Tru-Width sweeps with the Perma-Loc adapter can seamlessly move the high-productivity sweeps.

The high-productivity sweeps use the current Perma-Loc adapter for 47-degree curved standard, N237614.

Depending on agronomic needs, producers have a choice of six rear harrow options included in the ProFinish Leveling System on the 2330 Mulch Finisher.

Rear hitch

A substantial rear hitch is available to give the 2330 the versatility to pull other tow-behind attachments. The rear hitch includes:

• Rectangular tube construction
• Telescoping hitch
• Serviceable drawbar
• 453-kg (1000-lb) tongue weight rating
• 13,000 gross vehicle weight (GVW) rating for five-section machines; 10,000 gross vehicle weight (GVW) rating for three-section machines
• Wiring harness for transport lights
