FEATURES
INTERNAL BASKET SCRAPERS
The internal basket scraper allows for a uniform field finish in wet conditions because the baskets do not need to be raised out of ground to avoid plugging and can stay in the ground 100 percent of the time. The basket scraper is standard on 2730 Combination Rippers ordered with knife-edge baskets. Field install kits are available for existing units.

VARIETY OF WORKING AND TRANSPORT WIDTHS AVAILABLE TO MEET PRODUCER NEEDS
The 2730 Combination Ripper is available in five machine configurations:
7S24 seven-standard rigid frame with 610-mm (24-in.) spacing
9S24 nine-standard rigid frame with 610-mm (24-in.) spacing
9S24 nine-standard folding frame with 610-mm (24-in.) spacing
11S24 11-standard folding frame with 610-mm (24-in.) spacing
13S24 13-standard folding frame with 610-mm (24-in.) spacing

The ability to set the true width of the 2730 into the track spacing setting on the GreenStar display delivers a 6 percent increase in productivity, allowing the operator to cover more acres in the same amount of time versus the competition. The true width is achieved through additional disk blades along with their tapered design to ensure consistent coverage and a level finish across the entire tillage pass.

MULTIFUNCTIONAL IMPLEMENT FOR SINGLE-PASS PRIMARY TILLAGE
The 2730 is a combination ripper that integrates four operational areas into one system. These four areas consist of disk blades, ripper shanks, rear closing disks, and finishing attachments. The ability to customize these components quickly, conveniently, and independently offers reduced cost of operation and maximum productivity.

The disk blades eliminate the need for multiple residue sizing passes into one single pass that reduces surface residue levels by 60 to 80 percent. The 2730s ability to mix and bury more residue leads to faster soil warming in the spring all while reducing negative impacts of disease and insect pressure.

The ripper shanks accomplish full hardpan fracture across the entire soil profile with their 610-mm (24-in.) spacing to create a porous air and water environment for root development. Along with the ripper shanks side-to-side spacing, it also features a 1270-mm (50-in.) fore-aft spacing that improves residue disbursement and contributes to the machines nearly plug-proof performance.

With TruSet or manual adjustment, the operator can set this system to leave a uniformly mounded profile covering each ripper track, or it can be adjusted to obtain a smooth, level surface ideal for minimum preparation for the next springs seedbed. With the walking tandem action, the closing system can follow the contour of the ground and eliminate plugs leading to a more consistent finish.

To achieve optimal field levelness and clod sizing, the operator can control the finishing attachment with in-cab, hydraulic controls. The finishing attachments can be set to constant down pressure, float, or in wet field conditions, rise completely out of the ground. This ensures the seedbed is best prepared for the least amount of pre-plant seedbed tillage passes before planting.

Typical percentage of residue cover remaining from the 2730 Combination Ripper is listed in the table below. These percentages do not consider variables such as the conditions of the residue, speed, and soil type.

TRUSET PROVIDES PRECISE DEPTH AND PRESSURE CONTROL FROM THE CAB ON THE GO
In just six seconds, 2730 Combination Ripper operators can manage their changing field conditions by making on-the-go adjustments for the entire implement from the tractor cab. TruSet enables users to adjust depths for the disks, rippers, and closing disks, and adjust the pressure on the active hydraulic rolling baskets all while covering acres.

As conditions change throughout the field, operators running the 2730 with TruSet can quickly and efficiently respond to varying soils, compacted areas, heavier residue, and moisture. Making customized adjustments that respond to these agronomic factors help customers maximize their yield potential.

Adjusting the 2730 Combination Ripper with TruSet can be done up to 200 times faster than the manual adjustment process using single-point depth control and cylinder stops. With short windows to perform tillage work, that critical time savings could be the difference in getting fields worked or not.

Operators no longer must sacrifice machine performance by deciding to forgo manual adjustments throughout the field. At the touch of a button, TruSet users can quickly respond to changing conditions such as running deeper over end rows or shallower on hilltops and lighter soils. TruSet users can optimize their 2730 depth adjustments to maximize tractor performance for more efficient fuel use, and lower overall operating costs.

TruSet also add precision to tillage operations. The system offers depth accuracy of 2.5 mm (0.1 in.) and more than doubles the number of depth setting increments on the 2730 Combination Ripper. This finite level of control enables 2730 operators to create the ideal soil structure, and evenly size and distribute residue for maximum yield potential.

HYDRAULICALLY ADJUSTABLE 660-MM (26-IN.) DISK BLADES
The 2730's large 660-mm (26-in.) disk blades are hydraulically adjustable and are set in a tandem-type configuration. The disks are available in either individual disk blades or gang-type configuration. The front and rear blades are set at an 18-degree angle on either 460-mm (18-in.) spacing for individual or 280-mm (11-in.) spacing for gang to provide an aggressive disking action.

The disks can be adjusted in-cab to be raised completely out of the ground or lowered to a maximum in-ground depth of 203 mm (8 in.). The disk blades operate in constant down-pressure, and the optimal operating depth can be set from the cab with TruSet or manually using stop collars on the hydraulic cylinder. The ability to independently adjust the front disks based on varying conditions allows the operator to optimize desired residue sizing and mixing.

The larger disks are designed of high-quality steel and made from a manufacturing process for extended performance provide the following benefits:
Size and bury residue
Level the soil profile
Mix the surface residue
Give full-width tillage up to 200 mm (8 in.) deep
Reduce blade wear

WALK-OVER TANDEM WHEELS OFFER MAXIMUM SUPPORT, STABILITY, AND FLOTATION
Walk-Over tandem wheels with larger tire options offer maximum support, stability, and flotation in the field. The staggered wheel design provides additional room for residue flow and obstacles all while providing a consistent working depth in uneven ground.

The Walk-Over tandem mainframe wheels come equipped with 57-mm (2.25-in.) plug-in spindles and eight-bolt hubs on the seven-standard models configured with VF320/70R15 mainframe tires, and 79-mm (3.125-in.) plug-in spindles and ten-bolt hubs on the seven-, nine-, 11-, and 13-standard models configured with either the 445/50R22.5 or 550/45-22.5 mainframe tires. The 11- and 13-standard models feature an active-hydraulic wing wheel to ensure a consistent operating depth with uniform leveling. These active-hydraulic wing wheels allow the 2730 machine to better follow the contour of the land versus rigid-mounted wing wheels on competitive models.

FORE-AFT RIPPER SHANK SPACING DELIVERS IMPROVED RESIDUE FLOW
The 2730 delivers improved residue flow by increasing the overall frame length and underframe clearance along with the fore-aft spacing of the ripper shanks.

The 1270-mm (50-in.) fore-aft spacing maximizes residue disbursement, and 953 mm (37.5 in.) of underframe clearance contributes to the machine's nearly plug-proof performance. The 2730 features 610-mm (24-in.) side-to-side spacing that accomplishes full hardpan fracture across the entire soil profile to create a porous air and water environment for root development and plant nutrient uptake.

MAINTENANCE-FREE COMPONENTS REDUCE DOWNTIME
Sealed, maintenance-free individual hub bearings on the 2730 Combination Ripper results in reduced downtime for the operator.

The sealed hub bearings increase productivity by reducing the amount of time needed to service the 2730 before operation and allowing operators to spend more of their valuable time in the field. The maintenance-free bearings have been extensively field tested to stand up in tough conditions, providing longer bearing life and reduced wear.

The 2730 employs a high-density polymer liner that allows the bearings to dynamically align the shaft in rough field conditions. The cast-bearing housing also allows for additional protection with the bearing wear guard built-in, which leads to increased reliability.

The 2730 features 78 percent fewer grease points than major competitors resulting in less, time-extensive maintenance and improving field productivity by up to 3 ha (7.5 acres) per day.

ACHIEVE DESIRED FIELD FINISH WITH HYDRAULICALLY ADJUSTABLE FINISHING ATTACHMENTS
The 2730 comes equipped with the optional hydraulically adjustable finishing attachments to achieve the desired field finish. The hydraulic rolling baskets can be set to three hydraulically controlled positions from the comfort of the cab. The heavy-duty coil tine harrow is rigid mounted to the frame and depth adjustments are made according to the rear closing disk system. Based on field finish needs, the 2730 less harrow option is also available.

The finishing attachments come in a knife-edge or coil tine configuration and prepares field for a reduced amount of secondary tillage passes before planting. Below are the benefits of each attachment:
Knife edge better option in heavier, wet soils. Recommended basket for rocky soil types.
Heavy-duty coil tine harrow preferred finishing attachment in heavy, poorly drained soils.

The rolling baskets can be hydraulically set to three different operating positions based on field conditions:
Down pressure a gauge on the front of the 2730 allows operators to set basket down pressure to ensure constant ground contact. Down pressure also allows for better sizing of slabs, clods, and root balls and will leave a level soil profile.
Float the baskets can be put in the float position using the selective control valve (SCV) on the tractor. This allows the weight of the basket to roll over the ground.
Raised the baskets can be lifted off the ground when encountering a wet area of the field to help eliminate any chance of plugging.

The active hydraulic down-pressure system allows the operator to increase the down pressure on finishing attachments up to 8274 kPa (1200 psi). Adjustments are made with a dial located next to the gauge. Down pressure should be set using the gauge and operated from the cab.
