- Updated design and styling
- Decreased horsepower and fuel requirements due to lighter weight1
- Easier serviceability with modular-design cutterbar
- Impeller, urethane or V-10 conditioners
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.
Conditioner types include:
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.
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.
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.
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.
An advantage John Deere has over most competitors is that the mower-conditioners will transport directly behind the tractor at the same width as its cut. Operators can transition from road to field configuration and back again quickly and easily.
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).
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:
Sized to the width of the harvesting equipment or spread wide to allow for maximum exposure
John Deere mower-conditioners allow you to customise windrows to match your needs.
Adjustable swath boards help direct crop coming through the conditioner assembly, providing a quick adjustment to windrow width.
C300, C350 and C400 Mower-Conditioner models come standard with forming vanes on the swath board (not available on C450 and C500 models). 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 customise windrow formation to match crop conditions.
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.
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.
