C500 Mower-Conditioner

C500 Center-Pivot Mower-Conditioner

The C500 Center-Pivot Mower-Conditioner from John Deere offers you the widest cut in the lineup. The 5-m (16.4-ft) wide platform is the center-pivot equivalent of the commercial-grade 500R Windrower Platform. The C500 is built to withstand the needs of custom operators and producers covering high acres in a season.

  • The C500 allows you to cut 10 percent more acres per day versus the C450
  • Four conditioner options – Impeller, V10 steel roll, urethane roll, or Tri-Lobe™ steel roll
  • Replace knives in a fraction of the time with quick-change knives
  • The C500 has an overshot cross auger that improves crop flow, providing optimal windrow formation:
  • Lifts blown down crop for a clean cut
  • Converges the crop and keeps it from stalling on the cutterbar to minimize recut
  • Converges the crop mat into the conditioning rolls for more consistent crimping

Cut more acres per season or cut the same acres in less time. The C500 improves productivity, helping you harvest more crop while the conditions are right.

Protect your crop with conditioner options to fit your needs

C400 Mower-Conditioner

Achieving the right conditioning action can significantly reduce dry down time. That means less time needed to cure, maintaining optimum feed values, and preventing leaf loss in legumes. Hay and forage producers have a wide variety of crops and conditions. That’s why John Deere mower-conditioners offer four different conditioners.

  • Conditioning reduces the time required for dry down
  • Multiple conditioner options match a wide variety of crop types
  • Faster dry down can increase nutrients retained in harvested crops
  • Suitable for traditional dry hay or haylage operations

Conditioner types include:

The Super Conditioner. Hay Conditioning Dries Faster and is Resilient

  • Impeller – ideal for light-stemmed grasses and alfalfa that respond well to scuffing of the stems
  • Urethane – a soft roll that provides excellent performance in legumes and grasses
  • V10 steel – increased crimping for faster dry down and improved wear life
  • Tri-Lobe™ conditioner – a premium, patented roll system that uses a chevron design to crimp and crush

Reduced maintenance and proven cutterbar reliability with 5-year coverage

John Deere cutterbar with individual modules

John Deere’s patented design cutterbar is made from individual, diagonal-cut modules, making serviceability easy. Each module can be removed for service individually, leaving the remaining cutterbar modules attached to the frame.

  • Nodular iron modules are highly resistant to impact damage
  • Large, heavy-duty idler gears reduce driveline speed and wear
  • Shear hub protection minimizes cost and decreases repair time in the field
  • Gauge shoes provide accurate control of cut height and protect cutterbar
  • Low-profile cutterbar allows the operator to cut at a flatter angle for improved cut quality and reduced wear on components
  • Common oil bath keeps internal components lubricated and reduce oil-level checkpoints

Because John Deere is confident in the reliability, every mower conditioner includes a 5-year warranty on cutterbar components. This gives you peace of mind knowing that if you do experience a warrantable failure, your machine is backed through your experienced, local John Deere dealer.

Shear hub

Each cutting disk is attached to a shearhub (driver) on the splined pinion gear. Power to the disk is interrupted when the driver shears to protect the internal components of the cutterbar. Damage is limited to exposed components and does not require disassembly of the cutting modules.

  • Reduces damage to the cutterbar and driveline components
  • Improved uptime with limited disassembly required

Gauge shoe

The gauge shoe setting determines the height of the crop stubble, but also prevents the majority of the cutterbar from being in constant contact with abrasive soils and rocks. The S250, S300, S350, C300, C350, and C400 have three height adjustments on the gauge shoe. The C450 and C500 come from the factory with six adjustments. Through service attachments, gauge shoe extensions are available to increase the number of adjustments if there is a need for higher stubble height.

Save time with quick-change knives

Quick-change knives

Having sharp knives on your machine is critical to harvesting all your crop and leaving a clean-cut field. Changing dull or bent knives is no longer a time-consuming job with the John Deere quick-change knife (QCK) system. There are no worries about having an impact or air compressor to change out the bolts. Simply insert the QCK tool into the disk and press down. The knives can be swapped out in seconds.

  • Reduce time to change knives by more than 50 percent over the bolted system
  • Base equipment for every John Deere mower conditioner
  • Kits are available to retrofit most 600, 800, and 900 Series Mower-Conditioners

Quickly prepare the mower-conditioner for transport

C400 in transport

An advantage John Deere has over most competitors is that the mower-conditioners transport directly behind the tractor at nearly the same width as its cut. Operators can transition from road to field configuration and back again quickly and easily.

  • Quickly move between fields when road transport is required
  • Minimize transport dimensions for improved narrow road transport

Side-pull model in transport position

Side-pull models (S250, S300, and S350) have the tongue positioned in the center of the frame and drivelines that enter from the top to improve transport width.

The C450 also has provisions to allow end-wise transport if you already have a dedicated transport cart. After backing the machine onto the cart and securing it, the tongue can be positioned parallel with the cutting head, allowing it to be towed by the tractor at under 2.8 m (9.2 ft).

Minimize dry down time with proper windrow formation

C400 windrow formation

Windrow formation is the final step of mower-conditioner functionality. Proper windrow formation is critical to reducing dry down times for dry hay and haylage or providing consistent chopping speeds and cut lengths for forage harvesting applications.

Characteristics of a quality windrow include:

  • Consistent volume of crop throughout the windrow
  • No clumping of material that can lead to inconsistent dry down
  • Square shoulder and even edges

Sized to the width of the harvesting equipment or spread wide to allow for maximum exposure

John Deere mower-conditioners allow you to customize windrows to match your needs.

  • Crop quality is maintained for higher feed value.
  • Windrow width can be matched to harvesting equipment.
  • Spread crop wide to maximize exposure (up to 337.8 cm [133 in.] with a properly equipped C400), further reducing dry down times.

S models. swath board adjustment

C models. swath board adjustment

Adjustable swath boards help direct crop coming through the conditioner assembly, providing a quick adjustment to windrow width.

  • No tools required for easy in-field adjustments
  • Used to make large adjustments to windrow width

Forming vanes mounted to swath board

0 Series Mower-Conditioners come standard with forming vanes on the swath board when available. Previously referred to as a wide swath kit, the forming vanes allow the mower-conditioner to increase windrow widths up to 25 percent and can be used to further customize windrow formation to match crop conditions.

  • Install all vanes directing crop flow outward to provide the widest windrow and fastest curing
  • Use vanes to direct heavy crop flow for more even distribution and consistent drying
  • When not in use, forming vanes can be stored on the machine for easy access

C400 wide windrow

The C400 produced the widest windrow when tested against a competitive machine, providing a windrow of conditioned alfalfa that was over 337.8 cm (133 in.). This was over 84 percent of the cut width for the C400 compared to 72 percent for the competition.

C500 narrow forming shield position

C500 wide forming shield position

Forming shields allow fine-tuning of the windrow width. This can allow you to easily match the windrow to your tractor’s tire spacing and prevent driving on cut and conditioned crop.

  • No tools required for easy in-field adjustments
  • Allow the operator to fine-tune the windrow width to match equipment and dry-down needs
  • Operator can easily set windrow width as required because of changes in crop type, conditions, and operating speed

R500 Rotary Platform

Oval disks with free-swinging knives

  • Reversible knives double the useful life
  • Located at the front of the cutterbar for ease of serviceability
  • Knives are identical, making servicing simple
  • Disks are made from high strength austempered steel, a heat-treating process that ensures the steel is thoroughly and evenly tempered for good wear characteristics
  • Cutting disks rotate toward the center of the platform except for disks 3 and 8, which rotate away from center. The paired rotation of disks 3 and 8 feed crop into the cross auger and help form more uniform edges of the windrow.

Wear caps

  • Wear caps are installed on each end of the cutting disks (except on the end disks where crop accelerators are used) to increase the wear life of the cutting disks and knife bolt nuts.
  • Wear caps are open on the end to prevent debris from packing in close to the nut, making hardware and knives easier to change.

Crop accelerators

Crop accelerator

mower, conditioner, c500, mower-conditioner
  • Crop accelerators are added to disks 1, 4, 7, and 10. Accelerators on disks 4 and 7 help to move crop from the diverging area between disks 3-4 and 7-8 and into the conditioning rolls.
  • Wear can be determined when a hole becomes visible in the end or the top of the accelerator and replacement is needed (performance may deteriorate before a hole is visible).
  • The one-piece design includes a heat-treated steel wear cap that protects the knife bolt nut and the end of the cutting disk.

Rotary strippers

Rotary stripper

  • Rotary strippers are bolted to the bottom of the inner converging drum on both the left side and right side of the platform.
  • Rotary strippers improve crop flow and convergence to the conditioner and minimize crop recirculation, improving windrow formation and crop quality.
  • Relocating the stripper to the converging drum provides increased wear life of the converging drum and less buildup of dirt and mud on the cutterbar, delivering lower cost of operation and increased uptime.
  • Rotary strippers are made from high-strength, austempered steel for improved wear life.

Easily change out and service the modular-designed cutterbar

The John Deere-patented-design cutterbar is made from individual, diagonal-cut modules. Servicing the modules is easy; the diagonally cut module design allows the modules to be removed individually while leaving the cutterbar attached to the frame. Idler gears transmit power through the cutterbar, increasing life of the platform and improving uptime.

Diagonal-cut modules

Cutterbar module

  • Removing seven bolts (two on each side of the module and three at the rear of the frame) enables a module to be removed from the cutterbar.
  • A rubber ring seals each module to the other and enables a common oil reservoir throughout the cutterbar.
  • The modules are made of high-strength, nodular iron castings.

Drive components

  • Each module consists of two idler gears and one drive gear. The large-diameter idler gears transmit power from module to module. The idler gears turn at a relatively slow speed for added durability.
  • A smaller-diameter pinion drive gear is used only to power the cutting disk. Power is not transmitted from one cutting disk to another except through the large- diameter idler gears.
  • Cutterbar modules are interchangeable across the entire cutterbar. Disk rotation is reversible and determined by the quill position (A) when assembling the disk module to the cutterbar. In some conditions, cutting performance can be improved through reversing individual disk rotation.

Maximize performance in varying crops with a choice of conditioners

The R400 and R500 Rotary Platforms offer choices of conditioners to meet producer needs. Varying crop types require different conditioners to deliver maximum performance in terms of window formation, cut quality, and drydown time.

Urethane conditioning rolls

  • The urethane roll conditioner works well in legumes, especially alfalfa and most all-grass crops. In general, roll conditioners are better suited for thick- stemmed, cane-type, and taller grasses more than 1.5-m (5-ft) tall.
  • Molded urethane rolls are formed by a cool molding process that does not distort or warp the steel core of the roll, ensuring the rolls are arrow straight and cylindrical, so they can be accurately spaced close together for uniform conditioning along the length of the roll.
  • The intermittent, recessed-cleat design gives more crimping edges for greater pressure per square inch, which results in superior conditioning and faster crop drying.

An adjustable swath board is included with the urethane conditioner roll option.

Free-swinging impeller

Pre-loaded tine impeller

The free-swinging impeller is available only on the R400 Rotary Platform. The pre-loaded tine impeller is only available on the R500 Rotary Platform.

The impeller conditioner works well in grass crops and legumes such as alfalfa. The V-shaped impeller tines produce a scuffing action by pushing crop against the adjustable conditioning hood, which helps remove the waxy surface of the stem to allow for faster evaporation of moisture. It is not recommended to use this conditioner with crops that are 1.5 m (5 ft) or taller.

The adjustable conditioner hood allows the operator to increase or decrease the distance between the hood and impeller tines. A tighter clearance provides more aggressive conditioning, while a wider setting allows for a higher volume of crop or less aggressive conditioning for use in legumes. The impeller rotor speed can also be adjusted by changing drive belt routing.

mower, conditioner, c500, mower-conditioner

The R400 has free-swinging impeller tines to help prevent damage to the conditioner if rocks or other solid objects are struck, reducing maintenance in adverse conditions. The R500 has a pre-loaded tine impeller with 162 tines. Tines are individually replaceable as needed for wear or breakage. Machines should never be operated with missing or broken tines, as it can cause an imbalance and vibration leading to damage.

  • 870 rpm – ideal for grasses
  • 630 rpm – suggested setting for legume crops
  • Increased impeller speed in taller crops may help reduce wrapping of rolls

V-10 steel conditioning rolls

Close-up of V-10 steel conditioning rolls

  • The V-10 steel conditioner rolls feature 10 angled flutes arranged in a chevron pattern, or V-pattern, along the length of the steel core.
  • Steel rolls offer improved wear life over urethane rolls, particularly in adverse crop conditions.

Advantages of the V-10 conditioner roll over the previous straight-flute design include:

  • Deep intermeshing angles for positive feeding and uniform conditioning throughout the entire length of the rolls
  • crimping edges for improved conditioning
  • Improved feeding
  • Improved windrow formation

An adjustable swath board is included with the V-10 steel conditioner roll option.

Replaceable end shafts

  • The shafts on the Tri-Lobe rolls are steel forgings that are then machined. These precision parts have minimal runout, which means the rolls themselves rotate precisely around their axis.
  • This precision enables the rolls to be adjusted to a minimum clearance for consistent conditioning along the length of the rolls.
  • The machined, forged roll ends are bolted into the core of the Tri-Lobe steel roll. In the event a roll end is damaged, the entire roll does not need to be replaced. Each shaft can be replaced individually, resulting in lower repair costs.
  • For serviceability, each roll end has two threaded holes so bolts can be used to pull the shafts from the steel core of the roll.

An adjustable swath board is included with Tri-Lobe conditioner option.

Tri-Lobe™ steel conditioning rolls

mower, conditioner, c500, mower-conditioner

Tri-Lobe steel conditioning rolls

Close-up of Tri-Lobe steel conditioning rolls

Tri-Lobe steel conditioning rolls are only available on the R500 Platform.

  • Tri-Lobe steel conditioning rolls have three intermeshing chevron lobes to crush the length of the stem for improved conditioning and faster drydown. The rolls are manufactured using a patented process.
  • The steel material increases wear life, especially in abrasive crops or soil conditions. Durability is a distinct advantage compared to other crusher-style rolls made of rubber or urethane. The chevron design of the rolls gives positive feeding and improved crop flow.
  • These rolls are well-suited for use in alfalfa where reduced curing time results in less bleaching of the crop. In heavy, thick-stemmed crops, such as sudan or sudex, the steel construction of the rolls does a very good job of breaking up the nodes on the stems to improve dry down.

Uniform windrow formation provided by frame, swathboard, and forming shields

The R400 and R500 Platforms deliver the latest advancements in windrow formation and uniformity from John Deere. Even, uniform windrows are critical to reducing drydown times for dry hay and providing consistent chopping speeds and cut lengths for forage harvesting applications.

Angled frame

Angled frame

  • The R400 and R500 features an angled frame to help merge the crop into the forming shields.
  • Merging crop directly behind the conditioning rolls provides a smoother transition to the forming shield, creating a more uniform windrow.
  • The swathboard is critical to windrow formation as it controls the angle at which the crop contacts the forming shields.
  • The welded pipe connecting the adjustment arm to the swathboard provides rigidity, preventing the swath board from bouncing and causing bunching in the windrow.

Forming shield

Forming shield adjustment

Forming shield attachment

  • Forming shields are easily adjusted to control the material flow, allowing the operator to match the windrow width to the harvesting requirements.
  • The windrow width is adjustable, without the use of tools, from a narrow windrow to a wide, fast-drying swath:
  • 4 cm (36 in.) up to 216 cm (85 in.)
  • NOTE: The windrow width depends on the crop conditions and type of conditioner.

Fixed fluff board

Fixed fluff board

  • The fluff board at the rear of the forming shields is fixed in the ideal position to deliver optimal performance in all crop conditions.

Quickly adjust rotary header settings with TouchSet™ technology

Adjustment to the rotary header can be made from the cab if TouchSet is ordered on the R500. You can adjust the formation shields and swath flap on the go.

Windrow width adjustments

To perform windrow width adjustments previously, you had to crawl under the machine to loosen and adjust the forming shields.

Adjust the swath flap from the display

Adjust the forming shield from the display

With TouchSet, the operator can select and adjust the swath flap and forming shield settings easily right from the display.

TouchSet is not compatible with the R400. It is compatible with the R500 equipped with any conditioner except for the impeller.

Windrow formation shield actuators

Customize a preset for a field or crop

TouchSet comes with a preset library of different crops to select while cutting. The crop selection automatically adjusts the header for that particular crop. You can also customize your own preset for a particular field and/or cutting. This allows you to quickly adjust the swath flap, forming shields, head tilt, and cutterbar speed.

Even crop flow from the edges with the overshot cross auger

The overshot cross auger delivers increased performance in windrow formation and cut quality. Improved crop flow from the edges of the platform toward the center provides an even flow into the conditioner, creating more uniform windrows. Additionally, crop is lifted off the cutterbar faster for improved cut quality in downed crops and reduced crop recut.

Improved crop flow from edges

  • The overshot cross auger features cupped flighting with a long pitch. The cupped shape makes the auger more aggressive in pulling crop from the edges of the platform and the converging drums.
  • Moving more crop from the edges of the platform toward the center delivers increased windrow uniformity, helping to reduce drydown time.

Reduced recut

Reduced recut

  • The center flutes of the cross auger have an aggressive edge to help lift crop off the cutterbar and feed it faster into the conditioner. This improves crop quality in reducing the potential for crop recut.
  • Moving crop faster into the conditioning rolls increases the overall capacity of the platform, enabling faster cutting speeds in heavier crop and more acres cut in a day.

Quick and easy serviceability with lightweight doors and replaceable top sheets

Lightweight plastic doors and bolted top sheets make service quick and easy.

Lightweight plastic doors

  • Lightweight plastic doors provide resistance to rock damage and are easier to open than original metal doors.
  • Bolted top sheets replace an original welded design and can be removed for increased accessibility or replaced in case of rock damage.
