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 edgesImproved 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 dry down time.

Reduced recutReduced 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.


John Deere value:

  • Increased overall platform capacity
  • Improved cut quality in down and lodged crops
  • More uniform crop flow into conditioner creates uniform windrows and reduced dry down time
  • Improved crop quality through reduced crop recut
  • Cross auger speed sensor monitors slip and alerts operator of potential plugging
  • Windrow uniformity reduces wet spots and potential for mold spots in bale



Choice of conditioners

The 500R offers choices of conditioners to meet customer needs. Varying crop types require different conditioners to deliver maximum performance in terms of window formation, cut quality, and dry down time.

Urethane conditioning rollsUrethane 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.

Close-up of V-10 steel conditioning rollsClose-up of V-10 steel conditioning rolls

The V-10 steel conditioner rolls feature 10 angled flutes arranged in a chevron, 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 are as follows:

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

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

Tri-Lobe steel conditioning rollsTri-Lobe steel conditioning rolls
Close-up of Tri-Lobe steel conditioning rollsClose-up of Tri-Lobe steel conditioning rolls

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.

Replaceable end shaftsReplaceable 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.


John Deere value:



Cost of operation

  • Three choices of conditioning options maximize performance in multiple crop types
  • Chevron pattern improves crop flow through conditioner and delivers consistent windrower formation
  • Steel rolls offer longer wear life
  • Tri-Lobe conditioner features bolt on replaceable roll ends

Rotary cutterbar components

The cutterbar consists of large oval disks with free-swinging knives. The knives are designed to retract when striking solid objects, reducing the potential for damage and delivering increased uptime. Wear caps, crop accelerators, and strippers deliver improved platform performance and lowered cost of operation in improving component wear life.

Oval disks with free-swinging knivesOval disks with free-swinging knives

Knives are reversible to double the useful life and are removed and replaced at the front of the cutterbar for ease of serviceability.


All cutting discs and knives are identical, making servicing simple and reducing the number of different service parts to have on hand for replacement.


The discs are computer-designed to maximize wear life and deliver ideal cutting performance. The discs 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 discs rotate toward the center of the platform with the exception of the #3 and #8 discs, which rotate away from center. The paired rotation of the #3 and #8 discs feed crop into the cross auger and help form more uniform edges of the windrow.

Wear capsWear 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.

Made of austempered heat-treated ductile steel.

Crop acceleratorCrop accelerator

Crop accelerators are added to discs 1, 4, 7, and 10. Accelerators on discs 4 and 7 help to help move crop from the diverging area between discs 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 disc.


Made of austempered heat-treated ductile steel.

Rotary stripper 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.


John Deere value:





Cost of operation

  • Computer-designed discs for ideal cutting performance
  • Crop accelerators and rotary strippers improve crop flow and windrow formation
  • Common knives and discs across cutterbar simplify servicing
  • Wear caps protect knife bolt from wear, increasing serviceability
  • Reversible knives double useful life and lower cost of replacement
  • Austempered steel increases life of wear components
  • Rotary strippers increase wear life of converging drum

Uniform windrow formation

The 500R platform delivers John Deere’s latest advancements in windrow formation and uniformity. Even, uniform windrows are critical to reducing dry-down times for dry hay and providing consistent chopping speeds and cut lengths for forage harvesting applications.

Angled frameAngled frame

The 500R 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 adjustment Forming shield adjustment
Forming shield attachmentForming 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:

  • 91.4 cm (36 in.) up to 216 cm (85 in.)

NOTE: The windrow width depends on the crop conditions and type of conditioner.


Attaching the forming shields to the platform is simple. The shields hang on a cantilevered bolt with spacer and are held in place with a single bolt.

Fixed fluff boardFixed 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.


John Deere value:




  • Angled frame into forming shield improves crop velocity and delivers windrow consistency
  • Rigid swathboard mounting structure reduces bouncing and improves windrow formation
  • Simplified forming shield attachment for easy hookup
  • Fixed fluff board eliminates adjustment point

Modular-design 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.

Cutterbar moduleCutterbar 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.

Cutterbar drive components Cutterbar 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. Disc rotation is reversible and determined by the quill position (A) when assembling disc module to the cutterbar. In some conditions, cutting performance can be improved through reversing individual disc rotation.


John Deere value:





Cost of operation

  • Ability to change disc rotation to affect performance in certain crop conditions
  • Diagonally cut, individual modules allow for replacement without dissembling entire cutterbar
  • Reduced wear of slower turning idler gears that transfer power through cutterbar increase durability
  • Interchangeable modules across entire cutterbar reduce cost of stocking replacement parts
