Durability and Flexibility

Maximized Profit

Modular Design

The fully encased modules provide superior hillside lubrication compared to competitive systems. This system contains any failure internally within a module as there is no free-flowing oil between each.

Shock Protection

Each module is protected from damage by an external shear hub located under the disc and on top of the module. The hub is designed to take the damage from a severe impact. Repair is fast and convenient by simply removing a few bolts and replacing the hub. There is no need to open the module exposing the lubricants to chaff and debris.

Added Durability

A simplified drive system with fewer parts and larger gears, bearings and interconnecting shafts creates added durability in the DC3 disc mower conditioners.

3-Year Warranty

All DC3 mower conditioner cutterbars are backed by a three-year warranty. This warranty covers all internal drive components.

Quick-Change Knives

For the ultimate in convenience, all DC3 mower conditioners are equipped with quick-change knives. Simply use the provided tool to change knives in seconds. Spend more time mowing and less time with maintenance.

Knife Options

Every field and every cutting has its own challenges. To fine tune your cut, several knife options are available to meet any condition. Options include various degrees of twist, serrations and a knife for rocky fields.

Cutterbar Tilt

All DC3 mower conditioners include hydraulic cutterbar tilt. Make changes to your cutting height without tools by simply repositioning a pin in the cylinder. As the tilt is built into the lift circuit an additional hydraulic remotes is not needed. DC3 mower conditioners require only two remotes on the tractor to operate.

Cleaner, Closer Cuts

The low-profile cutterbar with wide discs cut closer and cleaner to encourage faster crop regrowth.

Counter-Rotating Discs

More counter-rotating discs provide efficient crop feeding into the conditioners.

Efficient Crop Flow

The design of the cutterbar allows for reduced crop travel between cutterbar and conditioners, minimizing plugging. The driveshaft is on the left end only, for reduced clutter and cost.

Co-Rotating Disc Eliminated

The larger diameter discs allows for the elimination of co-rotating discs on the 13' models and allowing for only one set on the 16' models.

Center-Pivot Models DC133 and DC163

Long-Lasting Durability

The cutterbar on the DC3 series center pivot mower conditioners features a combination of larger disc diameters and wider conditioning systems that allow a short and smooth transition of crop flow to the conditioning system for improved windrow consistency in tall crops.

The larger, heavier discs allow for greater shock protection and lower cutting heights at a reduced angle for consistent cut height without scalloping.

The innovative cutterbar design aids in the elimination of co-rotating discs from the 13’ model and one set from the 16’ model.

Cutterbar Access

Easy Access

The Case IH Disc Mower Conditioners are designed to keep you running longer. Easily access the cutterbar to make adjustments or repairs.

Bi-Fold Doors

Unlike the competition, the bi-fold poly doors on the DC133 and DC163 provide full access to the cutterbar and its components. The poly construction resists dents from foreign objects to keep the machine looking better longer.
Single-Piece Hood

The single-piece hood on the DC93 and DC103 lifts and locks for full access to the cutterbar. A poly insert protects the hood from impact from foreign objects. The right-hand shield also lifts for access to the cutterbar end and to narrow the unit for road transport.

Conditioners

Best-in-Class Conditioning

The wider conditioners on the Case IH Disc Mower Conditioner series allows for a thinner crop mat, leading to uniform conditioning and greater sun exposure to the wider swath for faster dry down. There is almost a 1-to-1 cut width to conditioner ratio on the DC103 and DC 133 models. The torsion-bar roll-pressure design applies equal force to the conditioning rolls for greater consistency.

Easy Adjustments

The torsion bar design has a single point of adjustment to fine-tune the roll pressure. No tools are needed to quickly adjust the roll pressure to provide the ideal conditioning of your crop.
Rubber-on-Rubber

For thorough conditioning of leafy crops, the chevron rubber rolls provide full-stem crimping and cracking while delicately handling the leaves. Constructed with high-wear rubber for years of life. Rubber rolls are available on all models.
Steel-on-Steel

Chevron steel-on-steel conditioning rolls offer long life and durability in abrasive soils or rocky conditions. The chevron pattern provides aggressive full-stem crimping — a true advantage in cane-type crops and high-volume grasses. Steel rolls are available on the DC103, DC133 and DC163.
Flail Conditioning

The Case IH flail system provides a scuffing action on the stem, removing the waxy outer layer for faster dry-down in grass. The semi-swinging design ensures the crop is released at the optimum position to create fast drying, uniform windrows. Available on all models.

Hitches

Maximum Turning Performance

Choose either the drawbar swivel hitch or two-point swivel hitch and get maximum turning performance with zero driveline wrap-up. PTO power is transferred from the front swivel gearbox to a second swivel gearbox at the rear of the tongue that maintains perfect alignment of the driveshaft to the cutterbar gearbox.

Drawbar Swivel Hitch

Available as a standard option on the DC133 and DC163 and an additional option on the DC103.
Two-Point Swivel Hitch

Available as a standard option on the DC133 and DC163 and an additional option on the DC103.
Clevis Hitch

A simple clevis hitch is standard on the DC93 and DC103

Adjustments

No Tool Adjustments

Several systems on the disc mower conditioners can be adjusted without tools, letting you get into the field faster.

Windrow Formation- Swathgate and forming shields are easily adjusted without tools. Spread wide or narrow to fit your needs
Conditioning Roll Pressure- A single point of adjustment fine tunes the roll pressure
Knife Maintenance- The provided tool allows you to change the quick-change knives in seconds
Cutting Height- Repositioning a pin in the hydraulic tilt cylinder changes the cutting height

Testimonial

Case IH DC Series Disc Mower Conditioner Crushes the Competition

“We’ve had two Case IH Disc Mower Conditioners and they just do a great job. The adjustments are simpler than with competitive models. You set the machine on the ground with your hydraulics and go. The red machines are simple, reliable and easy to deal with. In the past, we ran competitive equipment, but the Case IH DC Series is far and away a better machine.”
