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.
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.
An adjustable swath board is included with the urethane conditioner roll option.
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.
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.
Advantages of the V-10 conditioner roll over the previous straight-flute design include:
An adjustable swath board is included with the V-10 steel conditioner roll option.
Tri-Lobe steel conditioning rolls are only available on the R500 Platform.
An adjustable swath board is included with Tri-Lobe conditioner option.
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.
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.
To perform windrow width adjustments previously, you had to crawl under the machine to loosen and adjust the forming shields.
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.
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.
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.
Lightweight plastic doors and bolted top sheets make service quick and easy.
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.
